Begin by peeling the small onions and trimming the tops, leaving the root intact. Start a gentle downward cut to create the petal-like shape, ensuring not to slice through the base.

In a mixing bowl, combine all-purpose flour, paprika, garlic powder, salt, and black pepper. Stir well until thoroughly mixed.

In another bowl, whisk together the large eggs and buttermilk until smooth. This will be your binding agent.

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

Preheat your air fryer to 375°F (190°C) for about 5 minutes. Spray the coated onions with cooking spray and arrange them in the air fryer basket.

Cook for 15-20 minutes until golden brown and crispy.

Let the crispy mini blooming onions cool briefly before serving with various dipping sauces.
