Ingredients & Substitutions

What’s special about this Air Fried Crispy Onion recipe is how such humble, everyday ingredients can transform into something truly spectacular. Each ingredient is selected for maximum flavor and texture—simplicity at its absolute best, with endless room for little twists if you’d like.

Yellow Onions (2 medium to large): Classic yellow onions hit the sweet spot for both flavor and texture, turning deliciously crisp as they cook. You can substitute with red onions for a bolder bite and more dramatic color.
Cooking Oil (1 tablespoon): A touch of neutral oil (like vegetable, canola, or even avocado oil) helps the onions crisp up beautifully—no heavy or greasy finish here! Olive oil can work in a pinch, but keep in mind it will add its own subtle flavor.

How to Make Air Fried Crispy Onion

Step 1: Slice and Separate

Start by peeling your onions and slicing them into even, thin rings. The thinner you go, the crispier the end result! Gently use your fingers to separate each layer into individual onion rings or strips—this helps each strand get maximum crisp for that authentic Air Fried Crispy Onion texture.

Step 2: Toss with Oil

Drizzle your prepared onions with a tablespoon of oil, then use your hands to toss and coat every piece lightly but thoroughly. Don’t be tempted to skimp or overload here—this tiny bit of oil is just right to turn the onions golden and crunchy during air frying.

Step 3: The Two-Stage Air Fry

Arrange the oiled onions in your air fryer basket in a mostly even layer. Cook first at 300°F for 10 minutes, pausing at the halfway mark to give everything a gentle mix—this helps them cook evenly. Next, drop the temperature to 240°F and continue air frying (gently mixing every 5 minutes) for another 15–18 minutes, until your Air Fried Crispy Onion is irresistibly brown and crunchy. Keep an eye out near the end, as crispness can happen fast!

How to Serve Air Fried Crispy Onion

Garnishes

For maximum flair, sprinkle these Air Fried Crispy Onions over everything from creamy green bean casseroles and mashed potatoes to hearty soups or even a loaded avocado toast. A fresh sprinkle of chopped parsley or chives on top adds a bright contrast and a little extra pop.

Side Dishes

They’re unbeatable on burgers, scattered over salads, tucked inside sandwiches, or even alongside a comforting main like baked chicken or roasted vegetables. For a true treat, mix these into your favorite mac and cheese or stir them into a rice pilaf for an instant upgrade.

Creative Ways to Present

Try piling your Air Fried Crispy Onion high on a rustic wooden serving board for people to grab as a snack, or use them as a crunchy “edge” around small ramekins of dip at your next gathering. You can even sprinkle them over homemade pizzas or blend them into savory trail mixes—honestly, the sky’s the limit!

Make Ahead and Storage

Storing Leftovers

If you somehow manage not to eat the whole batch at once, let your Air Fried Crispy Onion cool completely, then transfer them to an airtight container. They’ll keep crunchy on the countertop for up to three days—if your house is anything like mine, though, they rarely last that long!

Freezing

For longer storage, you can freeze your crispy onions. Spread them out on a tray and freeze until solid, then pop into a freezer bag. Re-toast in the air fryer for a couple minutes to revive their crunch—perfect for prepping ahead for holidays or big family dinners.

Reheating

When you’re ready to bring those leftovers back to life, just pop them in your air fryer at 300°F for 2–3 minutes. They’ll crisp right up again, as good as fresh—no sogginess, no sad onions here! Avoid microwaving, as it can make them chewy instead of crispy.

FAQs

Can I use red onions instead of yellow for Air Fried Crispy Onion?

Absolutely! Red onions work well and offer a bolder color and slightly sweeter, more pungent flavor. Just know they may turn out a little darker, which can look beautiful in salads and atop roasted vegetables.
Is it possible to make Air Fried Crispy Onion without oil?

You can skip the oil for an oil-free version, but keep in mind the onions may not get quite as evenly golden or crunchy. Even a small amount (just a tablespoon!) really makes a difference in achieving that perfect crisp.
Why do I have to stir the onions during air frying?

Frequent gentle mixing ensures the onions cook evenly and no bits get burnt or soggy. It’s the best way to make sure every strand gets that coveted crunch!
Can I double or triple this Air Fried Crispy Onion recipe?

You sure can—just make sure not to overcrowd your air fryer basket. Work in batches for the crispiest results, and remember to increase air frying time slightly if you’re cooking more at once.

Give these Air Fried Crispy Onions a try and watch as a simple onion turns into your new favorite kitchen secret. They’re impossibly crunchy, deeply flavorful, and so easy to make—one batch and you’ll never go back to store-bought!
