How to Make an Air Fryer Blooming Onion

Don’t let the fancy look intimidate you! With a sharp knife and a little patience, you’ll master the technique in no time.

Ingredients You’ll Need

• 1 large sweet onion (like Vidalia)
• ½ cup all-purpose flour
• 1 tsp paprika
• 1 tsp garlic powder
• ½ tsp cayenne pepper (adjust to taste)
• 1 egg + 2 tbsp milk (for egg wash)
• Cooking spray or olive oil
• Salt to taste

Step-by-Step Instructions

1. Prep the onion: Trim the root end, peel, and cut ½-inch from the top. Place cut-side down and make vertical slices (about 12–16) without cutting through the root.
2. Coat the onion: Gently separate the petals. Dip in egg wash, then dredge in the seasoned flour mix, ensuring every layer is coated.
3. Air fry: Spritz with oil and air fry at 375°F for 12–15 minutes, shaking halfway, until golden and crispy.
4. Serve: Pair with spicy mayo or ranch dressing. Devour immediately!

Tips for the Perfect Blooming Onion

• Choose the right onion: Large, round onions with tight layers work best.
• Don’t rush the coating: Take time to flour each petal for maximum crispiness.
• Use a rack: Elevate the onion in the air fryer for even cooking.
• Double the dip: For extra crunch, repeat the egg wash and flour steps.

---

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. Turn the onion upside down (root side up). Using a sharp knife, make vertical cuts from the top down, stopping about 1/2 inch from the root to create ‘petals.’ Gently separate the layers.
3. 3. Soak the Onion: Place the onion in a bowl and cover with buttermilk. Let soak for at least 30 minutes (or up to 2 hours).
4. 4. Make the Coating: In a separate bowl, mix 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, ensuring all petals are coated. Shake off excess.
6. 6. Air Fry: Preheat air fryer to 375°F (190°C). Lightly spray the air fryer basket with oil. Place the onion root-side down in the basket and spray lightly with oil.
7. 7. Cook for 10-12 minutes until golden and crispy. Check halfway and respray if needed.
8. 8. Make the Sauce: While cooking, mix mayonnaise, ketchup, horseradish, paprika, garlic powder, salt, and pepper in a small bowl.
9. 9. Serve immediately with dipping sauce.

Notes

For extra crispiness, double-coat the onion by dipping it back in buttermilk and flour a second time. If petals stick together, gently separate after the first few minutes of cooking.
