Description

Crispy Blooming Onion in the air fryer is a fun, golden appetizer with bold seasoning and a spicy dipping sauce, perfect for sharing and made without the mess of deep frying.


Ingredients

  • 1 large sweet onion (Vidalia or similar)
  • 1 cup all-purpose flour
  • 2 eggs
  • 1/2 cup milk
  • 1 tsp paprika
  • 1 tsp garlic powder
  • 1 tsp onion powder
  • 1/4 tsp cayenne pepper (optional)
  • Salt and black pepper to taste
  • Cooking spray or oil spray

For the dipping sauce:

  • 1/4 cup mayonnaise
  • 2 tbsp ketchup
  • 1 tbsp prepared horseradish
  • 1/2 tsp paprika
  • 1/4 tsp garlic powder
  • Salt to taste

Instructions

  1. Peel onion and slice off the top (leave root intact). Cut onion downward into 12–16 sections, not cutting through the root, to form petals. Gently separate layers.
  2. In one bowl, mix flour, paprika, garlic powder, onion powder, cayenne, salt, and pepper. In another bowl, whisk eggs and milk.
  3. Dip onion into egg mixture, ensuring coverage between petals. Dredge in flour mixture. Repeat both steps if extra crispy is desired.
  4. Place onion in air fryer basket and spray generously with oil.
  5. Air fry at 350°F (175°C) for 20–25 minutes, spraying with more oil halfway through.
  6. While it cooks, mix dipping sauce ingredients in a small bowl.
  7. Once golden and crisp, remove onion and serve warm with the dipping sauce.

Notes

  • Soak onion in cold water for 30 minutes after cutting to help petals bloom.
  • Double-dipping in flour and egg creates a thicker crust.
  • Use gluten-free flour or almond flour for dietary needs.
  • Reheat leftovers in the air fryer for 5–7 minutes at 350°F.
