These super-crispy, baked onion rings are a dead ringer (pun intended) for the deep-fried variety. A touch of cayenne adds nice heat. Slicing the onions into thin rings and baking them in a single layer on a large pan are the two key secrets to achieving a crispy texture. If you don't have a baking pan large enough to hold the onion rings, simply use 2 pans and switch their positions in the oven after you turn the onions rings. Pair them with a juicy lettuce-wrapped turkey or lean beef burger and serve as a meal or serve them as a party app at your next get together.


Cooking spray

3 spray(s)

Cornflake crumbs

1 cup(s)

Egg whites

1 large

1% low fat milk


All-purpose flour

¼ cup(s)

Onion powder

¾ tsp

Table salt

½ tsp, or to taste

Cayenne pepper

tsp, or to taste


1 large, yellow, sliced into 1/4-inch-thick rounds, separated into rings


  1. Preheat oven to 450°F. Coat a large, rimmed baking sheet with cooking spray.
  2. Spread cornflake crumbs on a large plate. In a shallow bowl or pie plate, whisk together egg white, milk, flour, onion powder, salt and cayenne pepper until blended.
  3. In batches, dip onion rings in egg mixture (letting excess drip off) and then dredge in cornflake crumbs, turning to coat both sides; place in a single layer on prepared pan.
  4. Coat onion rings with cooking spray and bake, turning once, until onion rings are golden brown, about 12 minutes; sprinkle with additional salt and pepper before serving, if desired. Yields about 8 onion rings per serving.
