Black Pepper Beef, Mushroom & Green Bean Stir-Fry – A 25-Minute Weeknight Winner

I still remember the first time I made a black pepper beef stir-fry that actually tasted like the ones from my favorite Chinatown spot in New York. I was standing in my tiny Manhattan kitchen, a block of beef sirloin on the cutting board, and a bag of green beans from the Union Square farmers market sitting next to the stove. This black pepper beef stir-fry with mushrooms and green beans is the recipe I wish I had back then — it’s the one I’ve perfected over years of testing, tweaking, and tasting. The coarsely ground black pepper gives it this bold, fragrant kick that pairs so beautifully with the earthy mushrooms and those bright, snappy green beans. Every time I make it, I think of my mother’s kitchen in Morocco, where she’d grind spices by hand and tell me that the secret to any great dish is layering flavor with intention. That same principle is at the heart of this easy beef stir-fry — quick enough for a Tuesday night, but impressive enough to serve friends.

Let me paint the picture for you: tender slices of beef sirloin, each one coated in a glossy, savory-black pepper sauce that clings like it belongs there. The mushrooms — I love using cremini or baby bella — get golden and almost meaty as they caramelize in the hot wok. And the green beans? They stay crisp and bright, with little charred spots from the high heat that add a subtle smokiness. The sauce itself is a beautiful balance of salty soy sauce, rich oyster sauce, and warm beef broth, all tied together with a touch of sugar and plenty of coarsely ground black pepper. It’s the kind of dish that makes you want to scoop up every last drop with steamed rice. The aroma alone — garlic hitting hot oil, beef searing, pepper blooming — will have everyone wandering into the kitchen asking what’s for dinner.

What sets this beef and mushroom stir-fry apart from others is the technique. I spent years training at Le Cordon Bleu in Paris, where I learned that the little things — a proper marinade, the right cut of beef, the order in which you cook each component — make all the difference. In this recipe, I use a simple cornstarch-and-soy marinade that tenderizes the beef and helps the sauce cling to every piece. I also cook the green beans and mushrooms separately before combining everything, a trick that ensures each vegetable retains its own texture and personality. And the black pepper? I use freshly and coarsely ground Tellicherry peppercorns — the same ones I buy from a spice shop in the West Village — because that fresh, citrusy heat is truly irreplaceable. One common mistake I see home cooks make is overcrowding the wok, which causes everything to steam instead of sear. I’ll show you exactly how to avoid that. 💡 mia’s Pro Tip: Let the beef come to room temperature for 10 minutes after marinating — it sears more evenly and stays tender.

Why This Black Pepper Beef Stir-Fry Recipe Is the Best

The Flavor Secret. This is not just another Asian beef and green beans recipe — it’s a carefully built layering of savory, peppery, and subtly sweet notes. The coarsely ground black pepper is the star here, but it’s supported by a soy-cornstarch marinade that does double duty: tenderizing the beef and creating a sauce that coats every ingredient like velvet. I learned this balance during my time in Paris, where the chefs emphasized that a great sauce should never overwhelm — it should elevate. The oyster sauce adds that deep umami richness, while the sugar rounds out the edges. Every bite is harmonious, with the pepper providing a gentle warmth that lingers without overpowering.

Perfected Texture. Texture is where so many stir-fries fall short, and it’s the one thing I obsess over. The beef in this easy beef stir-fry is sliced thin against the grain and marinated with cornstarch, which creates a protective coating that keeps it silky and tender even under high heat. The green beans are cooked just long enough to stay crisp-tender with a slight char, and the mushrooms are seared undisturbed so they develop a deep golden crust. Cooking each component separately — then combining them at the end — ensures every ingredient retains its own distinct texture. This is a non-negotiable technique I picked up from my Paris training, and it’s the reason this stir-fry tastes like it came from a restaurant kitchen.

Foolproof & Fast. From prep to plate, this stir-fry takes just 25 minutes — and that includes the 10-minute marinade. I’ve designed the steps to be logical and forgiving: the marinade does the work for you, the high heat does the rest, and the sauce comes together in the pan in under two minutes. Whether you’re a seasoned cook or a busy parent looking for a quick dinner, this recipe delivers consistent results. The ingredient list is short and uses mostly pantry staples, and I’ve tested every substitution so you know exactly what works. This is the kind of recipe you’ll commit to memory — and your family will request it again and again.

Black Pepper Beef Stir-Fry Ingredients

I pick up my green beans from the Union Square farmers market when they’re in season — those slender, bright French haricots verts are my weakness. The mushrooms I grab from the Asian grocery on Mott Street, where they have the freshest creminis and sometimes even shiitakes. And the beef? I always look for sirloin or flank steak from the butcher counter at my local market. There’s something grounding about choosing each ingredient with care — it reminds me of shopping in the medina in Morocco with my mother, where every spice and vegetable had a story.

Ingredients List

• 8 oz beef sirloin, thinly sliced against the grain
• 2 tbsp soy sauce
• 1 tbsp cornstarch
• 1 tsp black pepper, coarsely ground (preferably Tellicherry)
• 2 tbsp vegetable oil, divided
• 8 oz green beans, trimmed and halved
• 8 oz mushrooms, sliced (cremini, baby bella, or shiitake)
• 3 cloves garlic, minced
• 1 tbsp oyster sauce
• 1/4 cup beef broth
• 1 tsp sugar
• 1/2 tsp red pepper flakes (optional — for heat lovers)

Ingredient Spotlight

Beef Sirloin. This cut is lean, tender, and affordable — ideal for quick stir-frying. Look for slices about 1/4-inch thick, and always cut against the grain to shorten the muscle fibers. If sirloin isn’t available, flank steak or skirt steak are excellent substitutes; just be sure to slice them thin. The marinade with cornstarch and soy sauce helps break down the proteins, ensuring the beef stays juicy even under high heat. I’ve tested this with chicken thighs and extra-firm tofu too — both work beautifully, though cooking times vary slightly.

Green Beans. Fresh green beans provide that essential crisp-tender bite and a pop of color. I prefer slender beans because they cook faster and have a more delicate texture. When you stir-fry them over high heat, they develop little charred spots that add a subtle smokiness to the dish. If fresh green beans aren’t available, frozen whole green beans work well — just thaw and pat them dry before cooking to avoid steaming. Avoid canned green beans, as they’re too soft to hold up in a stir-fry.

Mushrooms. Cremini or baby bella mushrooms are my go-to for this beef and mushroom stir-fry — they have a deep, earthy flavor and a firm texture that sears beautifully. Shiitake mushrooms add an even more intense umami note, especially the dried ones (rehydrated and sliced). The key is to cook them undisturbed for the first minute so they develop a golden crust. If you’re not a mushroom fan, you can substitute bell peppers or snow peas, though the flavor profile will shift slightly.

Black Pepper. This is the hero of the dish. I use Tellicherry peppercorns from a spice shop in the West Village and grind them coarsely in a mortar and pestle — the aroma is citrusy, floral, and intensely warm. Pre-ground black pepper won’t give you the same fresh punch, so I highly recommend grinding your own. The coarsely ground texture also creates little bursts of heat as you eat, which is part of what makes this black pepper beef stir-fry so addictive.

How to Make Black Pepper Beef Stir-Fry — Step-by-Step

Trust me when I say this is one of the most forgiving and rewarding stir-fries you’ll ever make. Each step builds on the last, and as long as you keep your heat high and your wok hot, you’re on the path to a truly memorable meal.

Step 1: Marinate the Beef

In a medium bowl, combine the thinly sliced beef sirloin with soy sauce, cornstarch, and coarsely ground black pepper. Toss well with your hands or a spatula until every slice is evenly coated. Set aside for 10 minutes at room temperature. This short marinade is enough to tenderize the beef and create a silky coating that will help the sauce cling to each piece. The cornstarch also creates a light crust during searing, which adds texture and locks in moisture.

💡 mia’s Pro Tip: Don’t skip the 10-minute rest. If you’re in a rush, even 5 minutes helps — but 10 minutes allows the cornstarch to fully hydrate and the soy sauce to penetrate the meat. This is the same technique I used in Paris for velvetting beef, and it’s the single most important step for tender results.

Step 2: Stir-Fry the Green Beans

Heat 1 tablespoon of vegetable oil in a wok or large skillet over high heat until shimmering. Add the trimmed and halved green beans in a single layer if possible. Stir-fry for 2 minutes, tossing occasionally, until they turn bright green and develop slight char marks. Use a slotted spoon or tongs to transfer them to a plate and set aside. Cooking them first ensures they stay crisp-tender and don’t release water into the other ingredients later.

⚠️ Common Mistake to Avoid: Overcrowding the pan. If your wok or skillet isn’t large enough, cook the green beans in two batches. When too many beans hit the pan at once, the temperature drops and they steam instead of sear. You want that vibrant green color with charred edges — not pale, limp beans.

Step 3: Sear the Beef

Add the remaining 1 tablespoon of oil to the wok and heat until it’s nearly smoking. Arrange the marinated beef in a single layer — work in batches if needed. Let it sear undisturbed for 1 to 2 minutes, until a deep brown crust forms on the bottom. Flip and cook for another 1 to 2 minutes on the second side. Transfer the beef to the plate with the green beans. Searing in batches ensures the beef browns rather than steams, which is essential for that rich, savory flavor.

💡 mia’s Pro Tip: Use a pair of tongs to flip the beef slices individually. It takes an extra 30 seconds but ensures every piece gets that beautiful caramelized crust. The fond (browned bits) left in the wok is pure flavor — don’t wipe it out!

Step 4: Cook the Mushrooms

Add the sliced mushrooms to the wok (no extra oil needed — the residual oil from the beef is enough). Let them cook undisturbed for 1 minute so they release their moisture and start browning. Then stir-fry for 2 minutes, tossing occasionally, until they’re golden and tender. Add the minced garlic and cook for 30 seconds, stirring constantly, until fragrant. The undisturbed first minute is the key to getting those deep golden edges that make mushrooms so satisfying.

⚠️ Common Mistake to Avoid: Stirring the mushrooms too soon. If you toss them immediately, they release their water and start steaming instead of browning. Patience is everything here — let them sit, let them sizzle, and you’ll be rewarded with mushrooms that taste almost meaty.

Step 5: Combine and Sauce

Return the green beans and beef to the wok along with any accumulated juices. Pour in the oyster sauce, beef broth, sugar, and red pepper flakes if using. Toss everything together over high heat for 1 to 2 minutes, until the sauce thickens and coats each ingredient evenly. The cornstarch from the marinade will help the sauce come together quickly. You should see a glossy sheen on the beef and vegetables — that’s how you know it’s ready.

💡 mia’s Pro Tip: If the sauce seems too thin, mix 1 teaspoon of cornstarch with 2 teaspoons of cold water and stir it in. Let it bubble for 30 seconds — it will thicken instantly. This is a classic French technique called a “slurry” that I often use to adjust sauces at the last minute.

Step 6: Serve

Serve immediately over steamed rice. Garnish with a sprinkle of extra coarsely ground black pepper and a few sliced green onions if you have them. The dish is at its absolute best right off the heat — the sauce is glossy, the beef is tender, and the vegetables are vibrant. Don’t let it sit too long, as the green beans will continue to soften and the sauce will absorb into the rice.

⚠️ Common Mistake to Avoid: Letting the finished dish sit in the wok off the heat. The residual heat will overcook the beef and make the green beans limp. Transfer everything to a serving platter immediately, or better yet, serve it straight from the wok to the table.

Serving & Presentation

This Asian beef and green beans stir-fry is a complete meal when served over steamed jasmine rice, but it also pairs beautifully with noodles or even cauliflower rice for a lighter option. I love to plate it family-style in a large shallow bowl, with the beef and vegetables mounded in the center and a sprinkle of extra coarsely ground black pepper on top. A few thinly sliced green onions or a handful of fresh cilantro leaves add a bright, fresh finish that contrasts with the rich, peppery sauce. For an extra touch, I sometimes add a wedge of lime on the side — a quick squeeze brightens the whole dish and cuts through the umami.

When I serve this to friends in my Brooklyn apartment, I always set out a small bowl of chili crisp or sambal oelek for those who want more heat. It’s a habit I picked up from my mother, who always served her tagines with a tray of condiments so everyone could customize their plate. This stir-fry is naturally balanced as written, but a little extra heat or acidity never hurts. I also like to pair it with a simple cucumber salad dressed with rice vinegar and sesame oil — the cool, crunchy contrast is a perfect match for the warm, savory stir-fry.

For a truly memorable presentation, serve the stir-fry in a warm ceramic bowl and garnish with toasted sesame seeds and a drizzle of chili oil. The visual contrast of the dark beef, golden mushrooms, bright green beans, and white rice is stunning. I learned the importance of plating in Paris, where even a simple dish was served with intention. This is weeknight cooking, yes — but that doesn’t mean it can’t look beautiful.

Make-Ahead, Storage & Reheating

This easy beef stir-fry is at its absolute best fresh off the wok, but I know life gets busy. In my New York schedule, I often prep the ingredients ahead of time to make dinner even faster. Here’s how I do it: I slice the beef, trim the green beans, and slice the mushrooms up to a day in advance, keeping each in separate containers in the fridge. The marinade can be mixed in a bowl and tossed with the beef just before cooking. This cuts the active prep time to under 5 minutes when you’re ready to cook.

When reheating leftovers, the most important thing is to avoid the microwave — it tends to make the beef tough and the green beans soggy. Instead, reheat in a hot wok or large skillet over high heat. Add a tablespoon of beef broth or water to help revive the sauce, and toss constantly for about 2 minutes until everything is heated through. The high heat will restore some of the original texture to the beef and vegetables. I’ve learned this trick after many late-night leftover experiments in my NYC kitchen, and it truly makes a difference. If you’re meal-prepping, I recommend cooking the rice fresh and storing the stir-fry separately — then combining them just before eating.

Variations & Easy Swaps

One of the things I love most about this black pepper beef stir-fry is how adaptable it is. Whether you’re cooking for dietary restrictions, using what’s in your fridge, or just craving something different, there’s a variation here for you. I’ve tested each of these in my own kitchen, and they all deliver that same satisfying balance of savory, peppery, and fresh.

Spicy Sichuan Variation

For those who love bold, fiery flavors, this variation is a game-changer. Add 1 tablespoon of doubanjiang (fermented chili bean paste) along with the oyster sauce, and toss in 1 teaspoon of Sichuan peppercorns (lightly crushed) when you add the garlic. The doubanjiang brings a deep, fermented heat, while the Sichuan peppercorns add that signature numbing tingle that makes the dish so addictive. I discovered this combination during a trip to Flushing, Queens, and it’s been a favorite ever since. The black pepper still shines through, but it’s now part of a much more complex heat profile. Serve with extra steamed rice to balance the spice.

Gluten-Free Version

Making this beef and mushroom stir-fry gluten-free is straightforward and doesn’t compromise flavor. Swap the soy sauce for tamari (which is naturally gluten-free and has a similar taste), and use a gluten-free oyster sauce — many brands are available now, or you can substitute with a mix of mushroom stir-fry sauce and a splash of fish sauce. The cornstarch is already gluten-free, and all the vegetables are naturally safe. I tested this version for a friend with celiac disease, and she said it was the best stir-fry she’d had in years. The key is to check your beef broth label too, as some brands contain gluten. Everything else in the recipe is naturally gluten-free.

Spring Vegetable Twist

When spring arrives and the farmers market is overflowing with fresh produce, I love swapping the green beans for asparagus or sugar snap peas. Asparagus should be trimmed and cut into 2-inch pieces; snap peas can be left whole. Both cook in about the same time as green beans — 2 to 3 minutes over high heat. I also add a cup of snow peas for extra crunch and sweetness. This version feels lighter and brighter, perfect for warmer weather. The black pepper sauce complements the delicate flavors of spring vegetables beautifully — I often add a teaspoon of fresh ginger along with the garlic for an extra layer of warmth. It’s a reminder that this recipe is a template you can adapt to any season.

Black Pepper Beef Stir-Fry Quick, Flavorful, and Perfect for Dinner

I still remember the first time I made black pepper beef stir-fry in my tiny New York City apartment — it was a Tuesday, I was exhausted from a long shift at the restaurant, and I craved something quick, bold, and deeply satisfying. Growing up in Morocco, my mother always taught me that the best meals come together in a single pan, with layers of spice and warmth that hug you from the inside. When I moved to Paris for culinary school, I learned to respect the precision of French sauces, but I never forgot that Moroccan home‑cooking truth: a little heat, a little sweetness, and a lot of love can turn simple ingredients into something unforgettable. This quick beef stir-fry recipe brings all of that together — tender strips of beef, vibrant bell peppers, and a glossy black pepper sauce that hits every note.

Picture this: the sizzle as beef hits a screaming hot wok, the fragrant burst of garlic and ginger, the way the sauce clings to each slice like a velvety coat. Freshly ground black pepper adds a warm, floral kick that’s miles away from the dusty stuff in a shaker. The onions soften just enough to sweeten the pan, and the bell peppers keep a satisfying crunch. Every bite is a balance of savory, sweet, and peppery heat — a dish that feels both comforting and exciting, perfect for a weeknight when you need dinner on the table fast but refuse to compromise on flavor.

My version stands out because I use a classic French technique — a quick marinade with cornstarch and soy sauce — to guarantee the beef stays silky and never tough. Then I finish with a touch of oyster sauce and brown sugar, a trick I picked up from a street‑food stall in Paris’s 13th arrondissement. The result is an easy pepper beef dinner that tastes like it took hours, but actually comes together in just 25 minutes. I’ve tested it a dozen times, and I promise you: follow these steps, and you’ll never order takeout again. 💡 mia’s Pro Tip: Always slice the beef against the grain for maximum tenderness. And don’t skip the cornstarch — it creates a delicate crust that locks in juices.

Why This Black Pepper Beef Stir-Fry Recipe Is the Best

The Flavor Secret — I grew up watching my mother toast whole spices in a dry pan before grinding them. That same principle lives here: freshly cracked black peppercorns, not pre‑ground. The aroma is intoxicating, with citrusy and piney notes that elevate the entire dish. Combined with a balanced sauce of soy, oyster, and a whisper of brown sugar, every mouthful hits that sweet‑savory‑spicy trifecta. For an extra layer, I sometimes add a splash of Chinese black vinegar — a trick from my Paris chef days that brightens the sauce without overpowering it.

Perfected Texture — The biggest challenge with stir‑fry is preventing rubbery beef. The solution is a quick velvetizing technique: a thin cornstarch coating seals in moisture, and cooking over high heat for only a minute per side ensures a tender, almost buttery bite. I also cook the beef in batches — overcrowding the pan lowers the temperature and steams the meat instead of searing it. This is the kind of detail I teach my culinary students in NYC, and it makes all the difference between a good stir‑fry and a great one.

Foolproof & Fast — This beef stir-fry dinner is designed for even the most hectic weeknights. Every ingredient is available at any US grocery store, and the steps are straightforward. No obscure techniques, no long marinades. The whole process takes 25 minutes, and you only need one wok or skillet. I’ve had absolute beginners make this recipe and text me photos with “I can’t believe I cooked this!” That’s the joy of a well‑tested recipe — it gives you confidence and a delicious meal in return.

Black Pepper Beef Stir-Fry Ingredients

I shop for my produce at the Union Square Greenmarket in NYC, where the bell peppers are so sweet they practically taste like candy. For the beef, I head to a butcher in Chinatown who always slices it perfectly against the grain. But honestly, even supermarket ingredients work beautifully here — the technique does the heavy lifting.

Ingredients List

• 1 lb beef sirloin, thinly sliced against the grain
• 2 tablespoons soy sauce
• 1 tablespoon cornstarch
• 1 teaspoon freshly ground black pepper (plus more for garnish)
• 2 tablespoons vegetable oil (or avocado oil)
• 1 red bell pepper, sliced into strips
• 1 green bell pepper, sliced into strips
• 1 medium onion, sliced
• 3 cloves garlic, minced
• 1 tablespoon oyster sauce
• 1 tablespoon brown sugar (packed)
• ½ cup beef broth (low‑sodium)
• 1 teaspoon sesame oil
• Green onions, sliced for garnish

Ingredient Spotlight

Beef Sirloin — This cut is lean, tender, and affordable. Look for bright red meat with even marbling. If you can’t get sirloin, flank steak or ribeye work well — just slice very thin against the grain. For a budget option, try top round; it’s a little tougher, so marinate an extra 10 minutes.

Freshly Ground Black Pepper — Whole peppercorns have a complex flavor that fades quickly once ground. I crack mine just before using — it makes the dish pop. If you only have pre‑ground, add an extra ½ teaspoon to compensate for lost intensity.

Oyster Sauce — This is the umami backbone. It adds a subtle sweetness and depth that soy sauce alone can’t provide. Vegetarian? Use mushroom stir‑fry sauce or hoisin with a splash of soy. But the real deal is best.

How to Make Black Pepper Beef Stir-Fry — Step-by-Step

Let’s get that wok screaming hot! This recipe moves fast, so have all your ingredients prepped and within reach. You’ve got this.

Step 1: Marinate the Beef

In a medium bowl, combine the sliced beef, soy sauce, cornstarch, and freshly ground black pepper. Toss until every strip is coated. Let it rest for 10 minutes — this helps tenderize and season the meat. Don’t skip the cornstarch; it’s the secret to that silky texture.

💡 mia’s Pro Tip: For extra tender beef, add 1 tablespoon of water or a splash of Shaoxing wine to the marinade. The liquid helps the cornstarch penetrate the meat fibers better.

Step 2: Sear the Beef

Heat 1 tablespoon of vegetable oil in a wok or large skillet over high heat until it shimmers. Add the beef in a single layer — don’t crowd the pan. Let it sear undisturbed for 1 minute, then stir‑fry for another 1–2 minutes until browned but still pink inside. Remove beef to a plate.

⚠️ Common Mistake to Avoid: Overcrowding! If the beef steams instead of searing, it will be tough. Cook in two batches if necessary.

Step 3: Stir-Fry the Vegetables

Add the remaining 1 tablespoon of oil to the wok. Toss in the bell peppers, onion, and garlic. Stir‑fry over high heat for 2 minutes — you want them crisp‑tender, not limp. The edges should start to char slightly for that smoky wok hei flavor.

💡 mia’s Pro Tip: If your wok is too dry, add a splash of water to create steam and help the peppers cook evenly. But don’t overdo it — you want dry heat to maintain the char.

Step 4: Make the Sauce

In a small bowl, whisk together oyster sauce, brown sugar, and beef broth until the sugar dissolves. Pour the mixture into the wok with the vegetables. Let it bubble for about 30 seconds.

⚠️ Common Mistake to Avoid: Adding the sauce before the vegetables are cooked. The sauce needs to reduce slightly to cling to the beef, so give the veggies a head start.

Step 5: Combine and Finish

Return the seared beef to the wok, along with any accumulated juices. Drizzle with sesame oil and toss everything together for about 1 minute, until the sauce thickens and coats every piece. The beef should be warm, the vegetables still vibrant, and the sauce glossy.

💡 mia’s Pro Tip: Taste and adjust seasoning — a pinch more black pepper at the end adds a fresh punch. Garnish with sliced green onions and serve immediately over steamed rice.

Serving & Presentation

In my home, we serve this black pepper beef stir-fry family‑style, piled high on a platter with a mound of fluffy jasmine rice on the side. The green onions add a fresh pop of color that makes the dish look restaurant‑worthy. For a touch of elegance, I sometimes sprinkle toasted sesame seeds over the top — a little trick from my pastry days in Paris.

Pair it with a simple cucumber salad dressed with rice vinegar and a pinch of chili flakes to cut the richness. Or, if you’re like me after a long day, just steam some frozen edamame and call it a meal. My NYC friends love this with a side of crispy spring rolls from our local Chinese takeout — a perfect fusion of homemade and neighborhood favorites.

Make-Ahead, Storage & Reheating

This quick beef stir-fry recipe is one of my go‑to meal prep dishes. I often double the batch on Sunday, then portion it into containers for busy weeknights when I know I’ll be running from the subway to the stove. The key is to undercook the vegetables slightly so they stay crisp after reheating.

I prefer reheating in a skillet over medium‑high heat — it restores some of the wok char that the microwave kills. If you must use a microwave, cover the dish with a damp paper towel and heat in 30‑second bursts to avoid drying out the beef. The sauce may thicken overnight; a little broth or water loosens it right up.

Variations & Easy Swaps

Spicy Szechuan Variation

For those who crave fire, this is my favorite twist. Add 1 teaspoon of red pepper flakes and 1 teaspoon of crushed Szechuan peppercorns along with the garlic in Step 3. The Szechuan peppercorns bring a numbing, citrusy tingle that makes the black pepper sing. It reminds me of the bustling night markets in Paris’s Chinatown — a perfect fusion of Chinese heat and French finesse.

Chicken or Tofu Swap

If you’re out of beef or feeding a mixed crowd, thinly sliced chicken breast works beautifully — just marinate the same way and cook until no longer pink. For a plant‑based version, press a block of extra‑firm tofu, cube it, toss with cornstarch and soy sauce, and pan‑fry until crisp. The sauce clings to tofu just as well as it does to beef. I tested this at a dinner party and my vegetarian friends said it was the best tofu they’d ever had.

Low‑Carb / Keto Option

When I’m feeling light after a weekend of NYC brunching, I swap the brown sugar for a monk fruit sweetener (Lakanto works great) and serve the stir‑fry over cauliflower rice instead of jasmine. The dish stays just as satisfying — the pepper and umami are so bold you won’t miss a thing. Even my kids eat it without complaint.
