Make crispy and flavorful onion rings in the PowerXL Air Fryer. Slice onions into rings, dip them in a mixture of flour, breadcrumbs, and your preferred seasonings. Preheat the air fryer to 375°F, then cook the onion rings for 8-10 minutes until golden and crispy. Serve them as a side dish or as a tasty topping for burgers and sandwiches.
