On a rimmed tray, mix the panko, garlic powder, onion powder, and salt. In a small shallow bowl, lightly beat the eggs. Place the flour in another small bowl.

Preheat the air fryer to 370°F.

Dip each onion ring into the flour, then tap to remove any excess flour. Dip it in the egg, coat with the panko mixture, and then place on a large plate.

Drizzle the onion rings with olive oil and transfer them to the air fryer basket, arranging them in a single layer with a little space around each ring. Don’t overcrowd the basket. Work in batches if necessary. Air fry for 8 to 11 minutes, or until golden brown and crisp. Repeat with any remaining onion rings. Serve with tartar sauce, if desired.
