Air Fryer Onion Rings
Air Fryer Onion Rings
Onion rings are a diner and drive-in staple: onion sliced into rounds, separated into rings, breaded, and fried until the coating turns crisp and golden around a soft, sweet center. This version uses an air fryer instead of a pot of hot oil, with a light mist of oil standing in for the oil bath.
The coating is a standard three-stage breading — seasoned flour, then egg, then panko — which sets up more reliably in an air fryer than a wet batter does. Buttermilk worked into the egg wash strengthens the coating and helps it brown, so a quick double-dip is the natural way to build a thicker crust.
Sweet onions like Vidalia or Walla Walla make a milder, sweeter ring; a regular yellow onion gives more of the sharp bite associated with classic fried rings. Either one crisps up the same way, so it mostly comes down to preference.
Crowding the basket is the one mistake that ruins the texture — the rings need room and airflow to crisp instead of steam, so work in batches. Serve them hot, straight out of the air fryer, with a dipping sauce like BBQ, tartar, or a ketchup-based fry sauce.
Ingredients
Serves 4 as a side or appetizer
The onions
- 2 large onions (about 450 g total), sweet (Vidalia or Walla Walla) or yellow, sliced into 1.5 cm rings, separated
The breading
- 65 g all-purpose flour
- 1 tsp seasoned salt (or ½ tsp kosher salt, plus extra garlic powder)
- ½ tsp garlic powder
- ½ tsp onion powder, optional
- ⅛ tsp cayenne pepper, optional
- 2 large eggs
- 80 ml buttermilk, optional, for a double-dip that improves adhesion and browning
- 75 g panko breadcrumbs
- 1 tbsp olive oil (or vegetable oil), for the panko
- oil spray, for the basket and tops
- fine sea salt, to finish
To serve
- BBQ sauce, tartar sauce, ketchup, or fry sauce, for serving
Directions
The onions
Cut the onions crosswise into ½ in (1.5 cm) rounds, then push the rounds apart so you end up with separate rings rather than solid slices.
The breading
Set up three shallow bowls. In the first, stir together the flour, seasoned salt, garlic powder, onion powder, and cayenne if using. In the second, beat the eggs — whisk in the buttermilk here too, if you’re doing the double-dip. In the third, toss the panko with the tablespoon of oil so the crumbs pick up some color as they cook.
Working one ring at a time, dredge it in the seasoned flour and tap off anything loose, dip it in the egg, then press it into the panko so the crumbs stick all over. For a sturdier coat that browns more evenly, double-dip instead: flour, egg, flour again, egg again, then panko.
To cook
Preheat the air fryer to 360°F (180°C) and mist the basket with oil. Lay the breaded rings in a single layer with space between them — crowding traps steam and stops the coating from crisping, so work in batches rather than piling the rings on top of each other. Mist the tops of the rings lightly with oil too; that mist is what drives the browning in an air fryer.
Air-fry for 8 to 10 minutes, until the coating is golden and crisp. Most rings don’t need flipping, but turn them over halfway through if your air fryer tends to brown unevenly.
To serve
Sprinkle each batch with a pinch of fine sea salt as it comes out. If you’re cooking in multiple batches, warm the earlier ones back through in the air fryer for a minute or two once the last batch is done, then serve everything together, hot, with your dipping sauce of choice.
Notes
For a pub-style beer-batter coat instead of the standard breading: whisk seasoned flour with ¾ tsp baking soda, then stir in one beaten egg and 1 cup (240 ml) beer to make a thin batter. Dip the rings straight into the batter, then into breadcrumbs, and air-fry a touch hotter and shorter than the standard breading, watching for drips of batter in the basket.
Cooked rings freeze well for up to two months. Reheat straight from frozen in the air fryer until hot and crisp again.
