Onions, along with garlic, are my kitchen staples. They add deeper flavor to dishes and make them more savory. Crispy onions also add a nice crunch to creamier dishes. But I just hate burning all that oil, which smells of onions, and can be hardly used for much else. So I prefer to make crispy onions without deep frying them so that I can enjoy their flavor without having to deal with the extra calories.

One of the best things about making crispy onions without deep frying is that they come out just as delicious as if you had fried them. The key is using the right ingredients, cooking temperature and correct to prevent them from going soggy.

Can you make crispy onions win an air fryer or an oven?

Yes, absolutely! Traditionally onions for casseroles are made by deep frying, but with ovens and air fryers, the same crispiness can be achieved effortlessly.

Ingredients for Crispy Onions


Onions: I have used brown onions. These have brown skin and cream-colored flesh. They tend to be pungent, add a deeper flavor to dishes, and make them more savory. Slice them thin, so they get crispier when combined with oil, flour, and bread crumbs.

Salt & Pepper: For seasoning

Oil: Use a neutral-smelling oil like canola oil, sunflower oil, peanut oil, avocado oil, and rice bran oil, to name a few. These oils also have a high smoking point which makes them perfect for air frying or oven frying. You only need a tablespoon or two. Skip it if you would like to make this recipe fat-free.

Flour: I have used all-purpose flour, which is perfect for adding structure to your onions. It also helps onions to stick to the bread crumbs and creates a crispy coating. Please see Frequently Asked Questions for substitutes.

Bread Crumbs:  I have used Panko bread crumbs. These are Japanese-style bread crumbs, made from crustless white bread. White bread is coarsely ground and lightly baked to make the crumbs dry and flaky. As a result, your fried food gets an extra light and crunchier texture. 

Step-By-Step Method to make Crispy Onions Without Deep Frying (Oven Or Air Fryer)

1. In a large bowl, mix flour, Panko bread crumbs, salt and pepper. Mix well.

2. Slice onions into thin slices, and add oil.

3. Toss onions into the flour mixture, and coat well.

4. Place coated onions in a single layer on a baking tray and bake at 180C for 25 to 30 minutes

5. At about half way mark ( after 10-15 minutes) carefully toss the onions around with a tong or spatula. This will ensure that the onions at the back, closer to the oven fan, do not burn.

Once crispy golden, cool the onions completely before storing them in an air-tight container in the refrigerator.
