Indulge in the irresistible crunch of homemade crispy onion rings made in your dash air fryer. Slice onions into rings, dip them in a mixture of flour, spices, and buttermilk, then coat with breadcrumbs. Air fry until golden brown and enjoy the perfect balance of crispy coating and tender onion. These onion rings are a great addition to burgers, sandwiches, or as a standalone appetizer.
