Enjoy crispy and flavorful onion rings made in the Instant Vortex Air Fryer. Slice onions into rings, then dip them in a mixture of flour, buttermilk, and spices. Coat the rings with breadcrumbs and place them in the air fryer basket. Cook at 375°F for 10-12 minutes until golden and crispy. Serve them as a side dish or as a topping for burgers and sandwiches.
