Preheat your air fryer to 375°F (190°C).

Prepare the onions by peeling them, trimming the tops and bottoms.

Mix the dry ingredients in a bowl—combine the flour, paprika, garlic powder, onion powder, salt, and pepper.

Whisk the eggs in a separate bowl until fluffy.

Coat each onion by dipping it into the flour mixture, then into the egg mixture, and finally rolling it in the panko breadcrumbs.

Spray the air fryer basket lightly with cooking spray. Place the coated onions inside, taking care not to overcrowd them.

Air fry the onions for 10-12 minutes until they're golden brown.

Cool the onions slightly after cooking before serving them with your favorite dipping sauce.
