Best Air Fryer Onions Recipe

Air fryer onions are the bomb! To top on hamburgers, serve as a side dish or add meat and make fajitas for dinner. Perfectly tender with a wallop of flavor.

Air Fry Onion

I mean this is probably the cheapest recipe ever, and adds the most flavor at the same time. Use any type you want from yellow to white or even red. They are the best burger topping ever you can actually make sweeter similar to our caramelized onions.

Give them a whirl and let us know what you think.

I thought the idea was so simple and didn’t even share the instructions the first few times I made them. Then I thought others might appreciate the temp and time it took so they could try these themselves. So, here ya’ go!

Similar to sautéed onions but a lot less work, they soften up just as nicely. I fiddled around with the seasonings a bit until I got it just right. They were so good my husband and I ate them right out of the bowl!

• I will say straight up that I am not really an onion lover but oh my goodness I couldn’t keep my hands off these.
• You could use whichever type you like, I prefer yellow or white personally.

Note that the thicker the strips or onion slices are the less they will soften. 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 too. 5 minutes will do the trick.

Onions in air fryer

We used 2 medium to large onions. Of course there is a wide variety of sizes when it comes to these so the amount of olive oil will vary. Just make sure they all glisten meaning they’re coated and you’ve added enough.

If you have 2 rather large ones you may need to add more than advised below in my recipe card.

You can see here below what I mean by glistening in the bowl. It also helps the seasonings to stick well, and the oil allows them to soften nicely. They’ll brown a bit on the ends and the longer you cook them the browner they’ll get.

Flip every 5 minutes for about 15 minutes cooking time total and beyond that it is up to you. This timing was perfection when we were making sauteed onions for our hamburgers though.

• 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.
• If you want to make the crispy crunchy kind, follow our crispy French fried onions recipe.

Once you have your onion with oil on top add whatever seasons you like. Garlic powder is a great add in too. I’ve used Old Bay at times because it’s my go to choice and that’s yummy.

This is what we used this time when it was a real hit:

• Onions
• Garlic salt
• Olive oil
• Onion powder
• Pepper

For a quick hamburger topping this is great to throw together. You can make a huge batch if you have a lot of people over in no time. Keep drawer closed so they stay warm until ready to serve.

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.
