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

Slice the onions into rings and separate them.

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

Dip each onion ring into the flour mixture, then into the buttermilk, and finally coat with breadcrumbs.

Place the coated onion rings in a single layer in the air fryer basket.

Drizzle olive oil over the onion rings.

Cook the onion rings in the air fryer for 10-12 minutes, flipping halfway through, until golden brown and crispy.

Remove from the air fryer and let cool slightly before serving.
