Ingredients in Air Fryer Crispy Onions

Here’s the beauty of it—just a handful of basic ingredients, and voilà, you’ve got crunchy perfection:

Onions: Sweet or yellow onions work best. Slice them thin for that delicate crunch. When they cook, they transform into golden, crispy goodness.

All-Purpose Flour: This helps create that signature crispy coating. It clings to the onions and fries up to a perfect crunch.

Cornstarch: Adds an extra layer of crispiness and helps prevent sogginess.

Seasonings: Think garlic powder, salt, pepper, and maybe a pinch of paprika. These bring flavor to every bite.

Oil Spray: A light spritz helps the onions crisp up in the air fryer without becoming greasy.

Instructions

Let’s dive into the steps to create this flavorful masterpiece:

Preheat Your Equipment: Set your air fryer to 375°F. This gives the onions the hot blast they need to get nice and crispy.

Combine Ingredients: In a large bowl, toss the sliced onions with flour, cornstarch, and your chosen seasonings. Make sure every strand is lightly coated.

Prepare Your Cooking Vessel: Lightly grease your air fryer basket with oil spray to keep everything from sticking.

Assemble the Dish: Spread the coated onion slices in an even layer in the basket. Don’t overcrowd—give them some space to breathe and crisp up.

Cook to Perfection: Air fry for about 12–15 minutes, shaking the basket every 5 minutes to ensure even browning. You’re looking for that golden-brown, crispy finish.

Finishing Touches: Let them cool for a few minutes—this helps them crisp up even more. And bonus: they smell amazing.

Serve and Enjoy: Pile them on anything and everything, or just eat them by the handful. No shame in that game.
