I mean what don’t I use these babies for? Always in my fridge to dice or slice and give every recipe not only added flavor but texture too. Air fry longer for more tender and char or just a bit to soften slightly, up to you. Give them a whirl and let us know what you think.

What Types of Onions to Use

Yellow is the most common, they are often referred to as all-purpose onions. You can bake, smoke, saute, or dice them up and add them to things like meatloaf. I choose those most often myself to make these fried onions the healthy way.

Helpful Tips

Note that when you slice the onion they need to all be the same width (or as close to it as possible). The thinner they are the softer and browner they will get in a shorter amount of time. Thicker seems better in our opinion as they do shrink a bit.

You can see here how large we made them. Then you’ll want to pick each large piece up and separate them so each piece can get coated with olive oil and seasonings. Throw these into a bowl and get the rest of your items out. Preheating your air fryer is always a good idea to make them golden brown at the end. 5 minutes will do the trick.

How Long to Air Fry Onions

Using the amount I suggest below, yellow or white, they will take about 15 minutes. If you have 2 rather large sizes you may need to add more than advised below in my recipe card. And there are a bunch of varieties and colors out there, red onions will take a bit longer since they are firmer in nature so when cooking onions of this variety you’d need to increase the timing to about 20 minutes still flipping often.

How to Season

To clarify what I mean by them glistening in the bowl, you can see what I mean here ensuring every piece is coated with oil. This coating also helps the seasonings to stick well, and to soften nicely. To add flavor I like to add some Old Bay, garlic powder and/or salt and pepper.

We make these thinly sliced onions for on top of our Instant Pot hamburgers all the time. These are not coated with anything like a blooming onion or onion rings are. They are naked essentially and meant to be a side dish or topping.

Breaded Onions in Air Fryer (Option)

If you want to make the crispy onions, like the crunchy kind, follow our crispy fried onions recipe. Those are lightly battered so you will get more of an onion ring texture of sorts.

What would you use air fryer onion for or with? Our favorite is atop burgers but or when making air fryer fajitas. There are so many other ideas out there though.
