Crispy bread crumb coating and a wet batter come together to make this diner classic. Combined with a tangy sauce, it's the perfect onion ring combination.

Instructions
Slice the onions into ½-inch thick rounds. Separate the rings and set aside.
Prepare three shallow bowls. In the first, add flour with salt, pepper, and garlic powder. In the second, whisk eggs with milk. In the third, add panko breadcrumbs.
Dredge each onion ring in flour, shaking off excess. Dip into the egg mixture, then coat thoroughly with breadcrumbs.
Place coated rings in a single layer in the air fryer basket. Do not overlap.
Lightly spray the tops with cooking spray. Cook at 375°F for 8–10 minutes, flipping halfway through, until golden and crisp.
Remove and serve immediately while hot and crunchy.
Notes
Substitutions and Variations
Use gluten-free flour and breadcrumbs for a gluten-free version.
Substitute buttermilk for milk for extra tang.
Add paprika or cayenne for heat.
Use crushed cornflakes instead of panko for a different texture.
Recipe Tips
Work in batches to avoid overcrowding the basket.
Spray lightly but evenly for better browning.
Flip carefully with tongs to prevent coating loss.
For extra crunch, double-dip in egg and breadcrumbs.
