Air Fryer Crispy Onions | Low Fat Fried Onions to Use In Many Dishes
There’s something magical about crispy onions. That golden crunch adds a burst of flavor and texture to everything from salads and soups to burgers and casseroles. But let’s be honest—deep-frying onions at home can feel like a messy, greasy ordeal. Enter the air fryer! With just a fraction of the oil, you can achieve that same irresistible crispiness without the guilt (or the lingering smell of fried food in your kitchen).
I first discovered the joy of air-fried crispy onions when I was trying to lighten up my favorite green bean casserole recipe. Traditional fried onions were delicious, but I wanted a healthier alternative that still delivered that satisfying crunch. After a few experiments (and a couple of burnt batches—oops!), I landed on this foolproof method. Now, these low-fat crispy onions are a staple in my kitchen, and I know you’ll love them just as much!

How to Make Air Fryer Crispy Onions
This recipe couldn’t be simpler. All you need are a few basic ingredients and your trusty air fryer. Here’s how to get that perfect golden crunch every time.
Ingredients
- 1 large onion (yellow or white works best)
- 1 tbsp olive oil or avocado oil
- ½ tsp salt
- ¼ tsp black pepper (optional)
- ¼ tsp garlic powder (optional, for extra flavor)
Instructions
- Prep the Onions: Thinly slice the onion into rings or half-moons. A mandoline works great for even slices, but a sharp knife will do the trick too.
- Toss with Oil & Seasonings: In a bowl, gently toss the onion slices with oil, salt, and any additional seasonings until evenly coated.
- Air Fry: Spread the onions in a single layer in your air fryer basket (work in batches if needed). Cook at 375°F for 8–10 minutes, shaking the basket halfway through, until golden and crispy.
- Cool & Enjoy: Let the onions cool for a few minutes—they’ll crisp up even more as they sit. Use immediately or store in an airtight container for up to 3 days.

Frequently Asked Questions
Can I use red onions for crispy onions?
Yes! Red onions work, but they have a higher water content, so they may take slightly longer to crisp up.
How do I store leftover crispy onions?
Keep them in an airtight container at room temperature for up to 3 days. If they lose their crunch, pop them back in the air fryer for a minute or two.
Can I make these oil-free?
A light coating of oil helps with crispiness, but you can try using a spritz of cooking spray for an even lighter version.
Why are my onions burning?
If your air fryer runs hot, reduce the temperature to 350°F and check them frequently after the 5-minute mark.
Can I use frozen onions?
Fresh onions work best—frozen onions release too much moisture and won’t crisp up properly.
Are these crispy onions gluten-free?
Yes! This recipe is naturally gluten-free, but always check your seasonings if you have dietary restrictions.
Once you try making crispy onions in your air fryer, you’ll wonder why you ever bothered with the deep-fried version. They’re lighter, just as delicious, and so easy to whip up whenever a recipe (or a snack craving) calls for them. Whether you’re topping a cozy casserole or adding crunch to your weeknight dinner, these low-fat fried onions are sure to become a kitchen staple. Happy air frying!
