Easy Air Fryer Blooming Onion – Just Like a Restaurant

There’s something undeniably fun about ordering a blooming onion at a restaurant—that crispy, golden exterior, the tender layers inside, and that irresistible dipping sauce. But let’s be honest: deep-frying at home can feel messy, intimidating, and, well, a little greasy. That’s where your trusty air fryer comes in! This Easy Air Fryer Blooming Onion gives you all the crunch and flavor of the restaurant favorite, with way less oil and cleanup.

I’ll never forget the first time I tried making a blooming onion at home. It was for a game-day gathering, and I was determined to impress my friends. After a few failed attempts (let’s just say my knife skills needed work), I finally nailed it—and the air fryer made it shockingly simple. Now, it’s my go-to appetizer for parties, movie nights, or just when I’m craving something crispy and satisfying. The best part? No one will guess it’s not straight from a deep fryer!

Why You’ll Love This Air Fryer Blooming Onion

If you’re on the fence about trying this recipe, here’s why it’s a must-make:

• Healthier than deep-fried: Uses just a fraction of the oil.
• Same crispy texture: The air fryer gives that perfect crunch.
• Easy cleanup: No greasy stovetop or splatters.
• Impressive presentation: It’s a showstopper appetizer!

How to Make an Easy Air Fryer Blooming Onion

Ingredients You’ll Need

• 1 large sweet onion (like Vidalia)
• 1 cup buttermilk
• 1 cup all-purpose flour
• 1 tsp paprika
• 1 tsp garlic powder
• 1/2 tsp cayenne pepper (optional for heat)
• 1/2 tsp salt
• Cooking spray or olive oil

Step-by-Step Instructions

1. Prep the onion: Slice off the top (not the root end!), then make vertical cuts to create “petals.” Gently separate the layers.
2. Soak in buttermilk: This helps the coating stick and adds flavor.
3. Coat the onion: Mix flour and spices, then dredge the onion, ensuring every layer is covered.
4. Air fry: Spray with oil and cook at 375°F for 12–15 minutes, until golden and crispy.
5. Serve hot: Pair with your favorite dipping sauce!

Tips for the Perfect Blooming Onion

Want to make sure your blooming onion turns out flawless? Here are my tried-and-true tips:

• Use a sharp knife for clean cuts—dull blades can crush the onion.
• Don’t skip the buttermilk soak—it tenderizes and adds tang.
• Shake off excess flour to avoid clumping.
• Spritz lightly with oil for extra crispiness.

This blooming onion is fantastic on its own, but why stop there? Here are a few pairing ideas:

• Burgers or sandwiches: Serve alongside a juicy Air Fryer Turkey Burger.
• Salad: Balance the crunch with a fresh green salad.

There you have it—a restaurant-worthy blooming onion without the deep-fryer mess. Whether you’re hosting a party or just treating yourself, this recipe is sure to delight. The air fryer magic keeps it light yet indulgent, and the best part? You get to enjoy that satisfying crunch guilt-free. So grab an onion, fire up your air fryer, and get ready to impress!

Instructions

1. Prepare the Crust:

1. 1. Prepare the Onion: Peel the onion and cut about 1/2 inch off the top. Leave the root end intact.
2. 2. Make Cuts: Turn the onion root-side up. Starting 1/2 inch from the root, make vertical cuts downward all around the onion to create ‘petals.’ Gently spread the petals apart.
3. 3. Soak in Buttermilk: Place the onion in a bowl and pour buttermilk over it, ensuring it gets between the petals. Let soak for at least 30 minutes.
4. 4. Mix Dry Ingredients: In a separate bowl, combine flour, paprika, garlic powder, onion powder, cayenne, salt, and black pepper.
5. 5. Coat the Onion: Remove the onion from buttermilk, letting excess drip off. Dredge in the flour mixture, pressing gently to coat all petals thoroughly.
6. 6. Air Fry: Preheat air fryer to 375°F (190°C). Lightly spray the onion with cooking oil. Place in the air fryer basket and cook for 12-15 minutes until golden and crispy.
7. 7. Make the Sauce: While cooking, mix mayonnaise, ketchup, horseradish, paprika, garlic powder, and salt in a small bowl.
8. 8. Serve: Carefully remove the onion from the air fryer and serve immediately with dipping sauce.

Notes

For extra crispiness, spray the onion with oil halfway through cooking. If petals aren’t spreading easily, make deeper cuts next time. Works best with large, round onions.
