Peel the small onions and trim off the tops, leaving the root intact. Cut into the onions to create petal-like sections without slicing through the root. Rinse under cool water and let them dry on a paper towel.

In a mixing bowl, combine the all-purpose flour, paprika, garlic powder, salt, and black pepper. In another bowl, whisk together the eggs and buttermilk until smooth.

Dip each prepared onion first into the flour mixture, then into the egg mixture, followed by rolling in breadcrumbs.

Preheat your air fryer to 375°F (190°C). Place coated onions in a single layer and lightly spray with cooking spray.

Air fry the onions for 15 to 20 minutes, checking for doneness at the 10-minute mark. Adjust time as needed for your air fryer.

Carefully remove from the air fryer, let cool slightly, and serve immediately with your favorite dipping sauces.
