Step 1

Prep & Slice: Start by preparing your onions. I slice them in half circles, about ¼ inch thick. You can slice them in whichever shape you like, just make sure the slices are large enough not to fall through the holes of the air fryer basket. The half-circle shape usually works great.

Step 2

Season: Then, toss them in olive oil and season with salt and pepper. I also use a pinch of All-Purpose seasoning.

Step 3

Air fry: Place the onions in an even layer in the air fryer basket in the preheated air fryer to 390°F (or 195°C). Do not overcrowd the basket.

Step 4

How long: Cook for 10 minutes, turning or shaking halfway through. Feel free to turn more than once. I think it is always a good idea to take a peek at how the onions are cooking and to determine if further time is needed.

Step 5

Flip, turn, and cook more if needed: After 10 minutes, check that they’re golden brown and crispy on both sides. If not, shake them again and continue cooking for a few more minutes until desired crispiness is achieved. I usually cook for another 2-3 minutes. So total of 13 minutes for my liking.

Step 6

Enjoy: When done, remove from the air fryer and serve as desired! These delicious red onions can be served as a side dish or used in salads or sandwiches for added flavor. You can also experiment with different seasonings such as garlic powder or smoked paprika for extra flavor!
