Step 1: Cut the Onion
- Peel the onion, leaving the root end intact.
- Place the onion root-side down on a cutting board.
- Starting about ½ inch (1 cm) from the root, make four evenly spaced cuts down to the board.
- Cut each quarter into 3–4 sections to create 12–16 petals.
- Gently separate the petals with your fingers.
Step 2: Prepare the Coating
- In a shallow bowl, combine the flour, paprika, garlic powder, onion powder, cayenne (if using), salt, and black pepper.
- In another bowl, whisk together the eggs and milk.
Step 3: Coat the Onion
- Dust the onion thoroughly with the flour mixture, making sure to coat between all the petals.
- Dip the onion into the egg mixture, allowing it to seep into the layers.
- Coat again with the seasoned flour, covering every petal for maximum crispiness.
Step 4: Air Fry
- Preheat the air fryer to 375°F (190°C) for 3–5 minutes.
- Lightly spray the onion with cooking spray or brush with olive oil.
- Place the onion in the air fryer basket, root-side down.
- Air fry for 18–22 minutes, or until the petals are golden brown and crispy.
Step 5: Serve
Carefully remove the blooming onion from the air fryer and let it cool for 2–3 minutes before serving.
