Step 1: Slice the Onions. Peel and slice onions into thin rings, aiming for about ¼ inch thickness.

Step 2: Set Up Your Coating Station. Prepare three bowls: one with flour, one with a beaten egg, and one with your breadcrumb mixture.

Step 3: Coat the Onion Rings. Dip each onion ring in flour, then egg, and finally coat with breadcrumbs.

Step 4: Preheat the Air Fryer to 375°F (190°C) for 3-5 minutes for maximum crispiness.

Step 5: Arrange the Onion Rings in the air fryer basket, avoiding overcrowding and lightly spraying with olive oil.

Step 6: Air Fry for 8-10 minutes, flipping halfway through for even browning.

Step 7: Cool on a paper towel-lined plate to absorb excess oil, and serve immediately.
