Instructions:

Peel onions and cut off the top. Cut into the onion to create petals, leaving the root intact.
In a bowl, mix flour, paprika, garlic powder, salt, and black pepper.
In another bowl, whisk together eggs and buttermilk.
Dip each onion into the flour mixture, then the egg mixture, and finally coat with breadcrumbs.
Preheat the air fryer to 375°F (190°C).
Spray onions with cooking spray and place them in the air fryer basket.
Air fry for 15-20 minutes, until golden brown and crispy.
Serve with your favorite dipping sauce.
