In a shallow dish, combine the flour, garlic powder, onion powder, and salt.

In another shallow dish, lightly beat the eggs.

Place the panko breadcrumbs in a third shallow dish.

Dry the onion rings with a paper towel. Dip each ring first in the flour mixture, then in the beaten eggs, and finally coat with the panko breadcrumbs so the coating sticks well.

Preheat the air fryer to 370°F. Lightly spray the air fryer basket with cooking oil spray. Place the onion rings in a single layer and cook for 8 to 12 minutes, turning halfway through if needed, until golden brown and crispy.

Carefully remove the onion rings with a spatula and serve warm, either on their own or with your favorite healthy dipping sauce.
