Peel each small onion and trim the tops and root ends, leaving the base intact. Cut down to create petal-like sections.

In a medium bowl, combine all-purpose flour, paprika, garlic powder, salt, and black pepper. Whisk until blended.

In a separate bowl, whisk together the eggs and buttermilk until smooth.

Dip each onion in the flour mixture, then the egg mixture, and finally roll it in breadcrumbs.

Preheat the air fryer to 375°F (190°C) for about 5 minutes. Spray the onions with cooking spray and air fry for 15-20 minutes.

Carefully remove from the air fryer and serve warm with dipping sauces.
