Step 1: Prepare the Onions

1. Peel the onions and trim the root end slightly so they can sit flat, but keep the root intact to hold the onion together.
2. Cut the onion into quarters or 8-10 segments, depending on how “bloomed” you want them, without slicing all the way through the root. Gently spread the onion petals apart.

Step 2: Make the Seasoned Flour Mixture

3. In a large bowl, combine flour, paprika, garlic powder, salt, and black pepper. Mix well. This seasoning blend will add flavor and help create that crispy coating.

Step 3: Prepare the Egg Wash

4. In another bowl, whisk together the eggs and buttermilk until smooth. The buttermilk adds a tangy taste and helps the flour coating stick to the onion.

Step 4: Coat the Onions

5. Dip each onion into the flour mixture, making sure the petals are well-coated. Shake off any excess.
6. Next, dip the onion into the buttermilk mixture, ensuring it’s coated evenly inside and out.
7. Return the onion to the flour mixture for a second coat to get it extra crispy.

Step 5: Preheat the Air Fryer

8. Preheat your air fryer to 375°F (190°C) for about 3 minutes. This ensures the onions cook evenly and become golden brown.

Step 6: Air Fry the Blooming Onions

9. Lightly spray the air fryer basket with cooking spray. Place the coated onions in the basket, leaving space between them so they can crisp properly.
10. Spray the onions lightly with more cooking spray to help with browning.
11. Air fry at 375°F (190°C) for 12-15 minutes, or until the onions are golden and crispy. Flip halfway through for even cooking if necessary.
