A Cozy Twist on Comfort Food: Low-Carb Bacon Cheeseburger Casserole

There’s something about the sizzle of bacon and the melty embrace of cheese that feels like a warm hug on a busy weeknight. I’ll admit, I used to think low-carb meals meant sacrificing flavor—until this casserole changed my mind. It all started one rainy evening when my family was craving cheeseburgers, but I wanted something hearty without the carb-heavy bun. What emerged from the oven was pure magic: layers of savory ground beef, crispy bacon, and gooey cheese, all baked into a dish that satisfied every craving. Now, it’s a staple in our home, and I’m thrilled to share it with you.

Gather Your Ingredients

This recipe is all about simple, wholesome ingredients that pack a punch of flavor. Here’s what you’ll need:

1 lb ground beef – I prefer 80/20 for the perfect balance of juiciness, but leaner works too.

6 slices of thick-cut bacon – Because everything’s better with bacon, right?
1 small yellow onion, diced – For that classic burger flavor.
1 clove garlic, minced – A little goes a long way to deepen the taste.

1 cup shredded cheddar cheese – Sharp cheddar adds a lovely tang.
½ cup shredded mozzarella – For that irresistible stretchy melt.
¼ cup sugar-free ketchup – Trust me, you won’t miss the sugar.

1 tbsp yellow mustard – A must for that authentic burger vibe.
1 tsp Worcestershire sauce – The secret umami booster.
2 large eggs – They bind everything together beautifully.

½ cup heavy cream – Adds richness without carbs.
Salt and pepper to taste – Don’t skimp—season as you go!

Let’s Get Cooking

Now, let’s transform these ingredients into a dish that’ll have everyone asking for seconds. Here’s how to make it:

Preheat your oven to 350°F (175°C) and lightly grease a 9×9-inch baking dish. A little butter or non-stick spray does the trick.
Cook the bacon in a large skillet until crispy. Transfer to a paper towel-lined plate to drain, then crumble into bite-sized pieces. (Pro tip: Save that bacon grease—it’s gold for sautéing the onions!)
In the same skillet, sauté the diced onion in the bacon fat until soft and translucent, about 3-4 minutes. Add the garlic and cook for another 30 seconds, just until fragrant.

Add the ground beef to the skillet, breaking it up with a wooden spoon as it browns. Season generously with salt and pepper. Once fully cooked, drain any excess fat if needed.
Stir in the ketchup, mustard, and Worcestershire sauce, letting the flavors meld for a minute or two. Remove from heat and set aside.

At this point, your kitchen will smell like a dreamy burger joint—resist the urge to dig in just yet! We’re only halfway there, but the best part (the cheesy, bubbly finish) is still to come.
