Crunchy and flavorful onion rings can be easily made in your PowerXL Air Fryer with the help of a food processor. Slice onions using the food processor's slicing attachment, dip them in a batter made with flour, buttermilk, and spices, and air fry until they are crispy and golden. Serve them as a side dish or as a tasty topping for burgers and sandwiches.
