Create crispy and delicious onion rings using your Gourmia air fryer and food processor. Use the food processor's slicing attachment to cut onions into rings. In a separate bowl, prepare a batter using flour, buttermilk, and spices. Dip the onion rings into the batter, then place them in the air fryer basket. Cook until they turn golden brown and crispy. Serve the homemade onion rings as a delightful side dish or snack.
