Preheat the air fryer to 375°F.
In a shallow bowl, combine the salt, onion powder, garlic powder, pepper, and panko breadcrumbs.
¾ tsp salt, ½ tsp onion powder, ½ tsp garlic powder, ¼ tsp pepper, 1½ cups panko breadcrumbs
Beat the eggs in a bowl. Place the flour in a separate bowl.
2 eggs, ½ cup all purpose flour
Dredge each onion slice in the flour. Then, dip in the egg mixture, letting the excess liquid drip off. Finally, toss in the panko mixture until fully coated.
1 large onion
Spray the bottom of the air fryer basket with cooking spray. Place the onion rings in the basket in an even layer, leaving space between each piece. You will need to do this in batches.
Drizzle olive oil over the onion rings, or use an olive (or avocado) oil spray.
Air fry for 7-8 minutes until the onion rings are golden brown and crispy.
Serve with your favorite dipping sauce. Enjoy!
