Air Fryer Onion Rings are perfectly crispy. Because so little oil is used they are much healthier than deep-fried onion rings and they are much crispier than oven baked onion rings.
Combine flour, paprika, and 1/2 teaspoon of salt in a shallow bowl.
In a second shallow bowl, whisk together buttermilk and egg. Whisk in 1/4 cup of the flour mixture.
In a third shallow bowl, combine Panko crumbs, 1/2 teaspoon salt, and 2 tablespoons oil. Stir with a fork until the oil is evenly distributed.
Dredge onion rings in flour mixture, then dip them in buttermilk mixture and then dredge in Panko crumb mixture.
Place in Air Fryer basket. Cook them in 2 batches so you don't crowd them. Set Air Fryer to 400 degrees for 12 minutes. Turn them over halfway through and sprtiz them with oil.
