Make crispy and flavorful onion rings in your Instant Vortex Air Fryer. Slice onions into rings, dip them in a mixture of flour, buttermilk, and spices, then coat them with breadcrumbs. Place the onion rings in the air fryer basket and cook at 375°F for 10-12 minutes, flipping them halfway through. The result is crunchy and delicious onion rings that are much healthier than deep-fried ones.
