Wonderfully crisp and crunchy onion rings are an all-time fave with burgers. These stay crispy for up to an hour, so you have plenty of time to fire up the grill.


Cooking spray

6 spray(s)


¼ cup(s)


1 large egg(s), or 1/4 cup fat-free egg substitute

Low-fat buttermilk

½ cup(s)

All-purpose flour


Hot pepper sauce

1 tsp, or to taste

Table salt

¾ tsp


½ tsp

Panko breadcrumbs

1 cup(s)

Uncooked onion(s)

16 oz, 2 (1/2-pound) sweet onion variety, cut into 1/2-inch slices


  1. Spread cornstarch on sheet of wax paper. Beat egg in medium bowl. Whisk in buttermilk, flour, hot sauce, salt, and paprika until smooth. Spread panko on separate sheet of wax paper.
  2. Separate onion slices into rings, selecting 20 largest rings (reserve remaining rings for another use). Coat onion rings, 5 at a time, with cornstarch, using fork to turn. Using another fork, dip coated rings into batter, letting excess batter drip off. Coat onion rings with panko, turning with clean fork. Place on baking sheet in single layer. Repeat to coat remaining onion rings.
  3. Depending on air fryer settings, preheat 6- to 8-quart air fryer to 360°F or 370°F for 3 minutes. Lightly spray basket with nonstick spray. Place 10 rings in basket. Spray onions again and air fry 5 minutes. Turn rings over and spray. Air fry until crispy, 5 minutes longer. Repeat with remaining onion rings.
  4. Per serving: 5 onion rings.
