How to Make the Air Fryer Crispy Onions

Step 1: Prep Your Onions

Slice onions into thin rings and separate them gently.

Step 2: Season & Coat

Toss the onions with a light drizzle of olive oil (or cooking spray) and sprinkle with salt, pepper, and garlic powder. Coat evenly.

Step 3: Load the Air Fryer

Spread the onion slices in a single layer in the air fryer basket. Cook in batches if needed so they crisp up instead of steam.

Step 4: Air Fry Until Golden

Air fry at 360°F (180°C) for 8–10 minutes, shaking the basket halfway through. Add extra time in 1-minute bursts if you like them extra crispy.

Step 5: Cool & Enjoy

Transfer onions to a paper towel–lined plate. They’ll crisp up more as they cool. Use immediately as a topping or store for later.

Pro Tips for Making the Recipe

  • Slice Evenly: Uniform slices mean perfectly even crisping.
  • Don’t Overcrowd: Keep onions in a single layer for the best crunch.
  • Season Smart: Taste as you go—onions shrink as they cook, so start with a lighter hand on the salt.
  • Make Them Extra Golden: A quick extra spritz of oil before the last minute of cooking boosts crunch.

How to Serve

These crispy onions are flavor powerhouses! Try them on:

  • Soups like creamy mushroom or tomato basil.
  • Salads for an irresistible crunch.
  • Burgers, sandwiches, and wraps for extra flair.
  • Classic casseroles like green bean casserole or mac and cheese.

Make Ahead and Storage

Storing Leftovers

Keep cooled onions in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate in a sealed container.

Freezing

Not recommended—the onions lose their crisp once thawed.

Reheating

Pop them back in the air fryer for 2–3 minutes at 350°F to revive their crunch.

FAQs

Can I use red onions instead of yellow or white?
Yes! Red onions add a slightly sweeter, sharper bite and work wonderfully here.

Do I need to soak the onions before air frying?
Nope, no soaking required. Just slice, season, and crisp them right up.

Can I make these oil-free?
Absolutely. A light spray of cooking oil helps with browning, but you can skip it for an oil-free version—they’ll still crisp nicely.

How do I keep them from burning?
Keep a close eye after the 7-minute mark. Every air fryer is different, so give them a shake and adjust as needed.
