Start by peeling the onions and cutting them into ¼-inch thick rings. Separate the rings gently, keeping larger ones intact.

In a large bowl, mix the flour, garlic powder, onion powder, paprika, salt, and black pepper.

In another bowl, pour the buttermilk. You can also add a pinch of salt here for extra flavor.

Place the breadcrumbs in a third bowl.

Take each onion ring and coat it in the flour mixture, shaking off any excess.

Dip the floured ring into the buttermilk, allowing any excess to drip off.

Finish by rolling the ring in the breadcrumbs, pressing gently to ensure they stick well. Repeat until all rings are breaded.

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

Arrange the onion rings in a single layer in the air fryer basket. Make sure not to overcrowd them, as this will affect the cooking.

Lightly spray the rings with cooking spray. This will help them become crispy.

Cook in the air fryer for about 10-12 minutes or until golden brown and crispy, flipping halfway through for even cooking.

Once cooked, remove the onion rings and place them on a paper towel to absorb any excess oil.
