Begin by peeling the small onions, removing the outer layers gently. Carefully cut into the onion from the top, creating petal-like sections while ensuring the root remains intact; rinse them lightly to remove any excess skin and pat dry.

In a mixing bowl, combine all-purpose flour, paprika, garlic powder, salt, and black pepper. Stir well until the dry ingredients are evenly mixed.

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

Begin coating each prepared onion by first dipping it into the flour mixture, then into the egg mixture, and finally roll in the breadcrumbs.

Preheat your air fryer to 375°F (190°C). Lightly spray the coated onions with cooking spray and arrange them in the air fryer basket. Cook for 15-20 minutes, or until golden brown.

Remove the Crispy Mini Blooming Onions from the air fryer and let them cool slightly. Serve warm with your favorite dipping sauces.
