How to Make Crispy Air Fryer Blooming Onion
Prepare the Onion: Start by slicing off the top of the large sweet onion, ensuring the root is still intact. This creates the blooming effect that makes this dish so charming!
Bloom the Petals: Gently separate the onion petals, being careful not to break them. Aim for about 16-20 petals to achieve that gorgeous bloom.
Mix the Coating: In a bowl, combine 1 cup of all-purpose flour, 1 tsp paprika, 1 tsp garlic powder, 1/2 tsp salt, 1/2 tsp black pepper, and optional 1/2 tsp cayenne pepper. This blend will bring amazing flavor!
Whisk the Wet Ingredients: In a second bowl, whisk together 2 eggs and 1/4 cup of milk until well combined. This wet mixture helps the flour coating stick to the onion.
Coat the Onion: Sprinkle the flour mixture over the onion, making sure to get in between the petals. Then, dip the onion into the egg mixture, followed by another generous coating of the flour mixture for extra crispiness.
Spray & Preheat: Spray the coated onion generously with cooking spray to ensure it gets that beautiful golden color. Preheat your air fryer to 375 °F (190 °C).
Air Fry the Onion: Place the blooming onion into the air fryer basket and cook for 12-15 minutes or until it s crispy and golden brown. Watch the petals carefully they should be tender when done!
Serve with Style: Remove the onion from the air fryer and serve immediately with your favorite dipping sauce. Enjoy the moment of amazement as you peel back the petals!
Optional: Try pairing it with a tangy ranch or zesty dipping sauce for an extra flavor boost!
