And the best part? They’re incredibly easy to make.

Why Make Crispy Onions in the Air Fryer?

Traditional fried onions require a pot of hot oil, careful temperature monitoring, and lots of cleanup. Air frying eliminates all of that while still creating beautifully crisp results.

Here’s why air fryer fried onions are a game changer:

  • Uses little to no oil
  • Much lighter than deep-fried
  • No greasy mess
  • Quick cooking time
  • Crispy texture without heaviness

If you already love your air fryer for quick dinners, this recipe proves it’s also perfect for crunchy toppings.

Ingredients

  • 2 large yellow onions, thinly sliced
  • 1–2 teaspoons olive oil spray
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • ½ teaspoon garlic powder
  • ¼ teaspoon smoked paprika (optional)

Choosing the Right Onion

Yellow onions are ideal because they:

  • Caramelize beautifully
  • Have balanced sweetness
  • Crisp well in the air fryer

You can also use white onions for sharper flavor or red onions for a slightly sweeter, colorful variation.

How to Slice Onions for Maximum Crispiness

The key to perfect low oil onion crisps is thin, even slicing.

  • Aim for about ⅛-inch thick slices
  • Use a sharp knife or mandoline
  • Separate the onion rings before seasoning

Thinner slices crisp better and cook more evenly.

Instructions

  1. Preheat your air fryer to 350°F (175°C).
  2. Slice onions thinly and separate into individual rings.
  3. Place onions in a large bowl and lightly spray with olive oil. Toss gently.
  4. Sprinkle salt, pepper, garlic powder, and paprika over onions. Toss again to distribute evenly.
  5. Spread onions in a single layer in the air fryer basket. Avoid overcrowding. Work in batches if needed.
  6. Air fry for 12–18 minutes, shaking the basket every 4–5 minutes.
  7. Watch closely during the last few minutes to prevent burning.
  8. Remove once golden brown and crisp.
  9. Let cool completely — they will crisp up even more as they cool.
