Introduction
Crispy Mini Blooming Onions cooked in an air fryer are a delicious and healthier twist on a classic appetizer. These bite-sized onion blossoms are perfectly seasoned, crunchy, and ideal for sharing or enjoying as a snack.

Ingredients
- 4 small onions
- 1 cup all-purpose flour
- 1 teaspoon paprika
- 1 teaspoon garlic powder
- 1 teaspoon salt
- ½ teaspoon black pepper
- 2 large eggs
- 1 cup buttermilk
- 1 cup breadcrumbs
- Cooking spray
Instructions
- Step 1: Peel the onions and trim off the tops. Carefully cut each onion to create petals, leaving the root end intact to hold the petals together.
- Step 2: In a bowl, combine the flour, paprika, garlic powder, salt, and black pepper to make the seasoned flour mixture. For extra spice, you can add a pinch of cayenne pepper.
- Step 3: In another bowl, whisk together the eggs and buttermilk until smooth to create the egg wash.
- Step 4: Dip each onion first into the seasoned flour, coating all petals, then into the egg mixture, and finally thoroughly coat with breadcrumbs.
- Step 5: Preheat the air fryer to 375°F (190°C). Lightly spray each coated onion with cooking spray to help achieve crispiness.
- Step 6: Arrange the onions in the air fryer basket without overcrowding and air fry for 15-20 minutes until golden brown and crispy.
Tips & Variations
- Use panko breadcrumbs for an extra crunchy texture.
- Try adding Parmesan cheese to the breadcrumb mixture for a cheesy flavor boost.
- If you prefer a spicier dish, increase the amount of paprika or add cayenne pepper to the flour mixture.
- Make sure the onions are dry before coating to help the batter adhere better.
Storage
Store any leftover crispy blooming onions in an airtight container in the refrigerator for up to 2 days. Reheat them in the air fryer at 350°F (175°C) for 3-5 minutes to restore crispiness. Avoid microwaving as it may make them soggy.

FAQs
Can I use regular milk instead of buttermilk?
Yes, you can substitute regular milk mixed with a tablespoon of lemon juice or vinegar to mimic buttermilk’s acidity, which helps tenderize the onions and improve coating adherence.
How do I prevent the onion petals from falling apart?
Be careful to leave the root end intact when cutting the petals. This acts like a hinge to hold the onion together while cooking. Also, handle the onions gently during the coating process.
