Hi, I’m Brittany, and I don’t like onions…unless they’re fried onions, or in this case air-fried onions!

Yep, that’s right: Your favorite holiday topping can now be made (pretty) healthy with the help of our new favorite kitchen gadget.

Air-fried onions.  Yea, you’re gonna like this one.

Do you have an air fryer yet?!?!  We got ours as a gift from a good friend and have been looooving it!

We’ve made air fried tofu, taquitos, french fries, croutons, ravioli! We’ve even put vegan jerky to the test.

Basically, whatever you would like to eat deep-fried can just as easily be made in the air-fryer with all the deliciousness but muuuuch less oil…or no oil at all, whatever your fancy!

And now, we’re adding air-fried onions to that list.

What are French fried onions?

For those of you aren’t familiar with the term, french fried onions are those crispy little wisps of deliciousness that typically top green bean casseroles and the like on your holiday table.

Now you know what I’m talking about, right?  They’re the best.

But unfortunately, like most deep-fried things, they are addictive yet pretty heavy on the tummy.  They are for me at least.

So, when T made a quick version in the air fryer a few months ago with all the taste but none of that heavy bloated feeling, I knew we had to share it here on the blog!

And the recipe we’re sharing with you guys today is pretty killer: easy to make, delicious, and rather healthy compared to their oil-laden counterparts.  Win-win-win!!

How to Make Air-Fried Onions

First, you’ll slice your onion thinly and soak them in plain non-dairy milk for at least 10 minutes. I’ve found this simple step is CRUCIAL for an awesome texture.

Next, you’ll whisk up some all-purpose flour (or gluten-free all-purpose for our GF friends) with a bit of salt + pepper.

We kept the flavor combo pretty basic here, but, as always, feel free to get creative. Here’s another great use for our Copycat Red Robin Seasoning or Homemade Chili Seasoning!

Now, it’s time to coat those soaked onions in your flour mixture! You’ll have a LOT of onion slices, so you may need to do this in batches. Toss ’em til they’re evenly coated and add them to the basket of your air fryer.

NOTE: We used an air fryer like this for this recipe. It has a basket that pulls out from the front of the air fryer. If you have a different kind of air fryer, you may need to adjust the method we outline below. Something to be aware of!

Finally, air fry those babies until they’re crispy and golden and just pure heavenly goodness.

How to Use Air-Fried Onions

First and foremost: GREEN. BEAN. CASSEROLES. Healthier holidays never tasted so good! 🙂

SALADS! As far as I’m concerned, every salad needs to have that crunchy element. These air-fried onions fit the bill beautifully. Personally, I adore them in our Vegan Caesar Salad.

Topping ALL the soups, stews, and chilis – like our Hearty Vegan Chili or Cozy Chicken(less) Stew.

A hearty flavorful dip topped with these crunchy strips of HEAVEN = the way to my heart. The first two recipes that come to mind are our Dairy-Free Tahini Feta Dip and Hot Walnut Sausage Dip. It would also be KILLER on some taco layer dip.

Of course, you can always eat them straight outta the air-fryer too. That’s perhaps my favorite way to eat these crispy vegan air-fried onions.

Let your creativity run wild; everything tastes better with these crispy swirls of yumminess on top!

  1. Add the onions to a shallow dish or bowl and pour the soy milk over them until they are just covered. Let soak for at least 10 minutes.
  2. While the onions soak, grab a mixing bowl. To it, add the flour, sea salt, and black pepper. Whisk until combined.
  3. Remove the onions from the almond milk. You can save this to add to soups or other savory dishes later. Toss your onions with the flour mixture, one small batch at a time to get a nice coating.
  4. Lightly spray the air-fryer basket and the flour-coated onions with oil. Add the onions to the basket and place in the air fryer.
  5. Cook the onions at 350F for 30-35 minutes, stopping to shake the basket every 5-10 minutes. Depending on the size of your onion and air fryer, you may want to do this in two batches.
  6. Remove the onions from the air fryer and let cool before eating. Use them to top all your holiday dishes like mashed potatoes, green bean casserole, and basically your entire life!


NOTE: Not all air fryers are the same, so the cooking time may need to be adjusted slightly. You do want to be sure you're using an air fryer with a fryer basket. We use and love this one by Cook's Essentials.

    1. Hi, Carly! We haven't tested this recipe in an oven, but I'm sure if you adjusted the time / temperature a bit, it would work! I'd think you'd also want to flip them halfway through.
  1. I made these according to the directions but it took less than half the time and they taste a little burnt. They are super crispy though.
  2. Ugh ok so like WoW!!!! 🤯 lol. This was a total disaster for me. I did everything according to the recipe down to measuring and leveling and measuring out teaspoons. But what I had when I opened my air fryer was a pretty wildly looking flour mess. I mean.....thank God everyone is in bed and this was just something I tried with one or two onions bc my hubby bought way too many veggies at the farmers market yesterday. I, just glad it wasn’t supper. So here is what I think the problem is. Idk when this recipe was put out....I need to check the date, but they are forever updating appliances as quickly as they are updating electronics it seems. So, I think it’s just a matter of the device people are using. I, am using the “power air fryer oven” that was an infomercial. It was advertised shortly after the “power grill “ .....I know I’m missing something there. But I first bought the grill. Was very impressed so I then bought the air fryer. But this particular air fryer does not have a “basket” as I seen you keep referring to. It has “racks” and layers of like 6 where I can slide the metal racks in and out of. It also has a rotisserie device in it and can do dehydration as well as the air frying etc. So when I opened up the air fryer after the recommended time, (and I also followed the recipe to the tee), what I had was a lot of very floury onions. They were not doughy or wet or soggy which was cool. But there was nothing appealing about them. I couldn’t, nor would I even try to, serve them to my dogs. But,,,,,,,I totally am NOT suggesting this was a crappy recipe. I seriously just think it is the device that was used. I know that with the proper device this would have turned out great. And that’s why I went ahead and tried to do it. So please don’t take offense to what I am saying, bc I totally think this would have been awesome. Again,,,,on the right machine. Sooooo.....I say all that to say this....,,I modified it and I tried it on another setting but still used ur advice on the seasonings. Well kinda. Lol. I added garlic powder and some Adobe. But Idk if they even came out ok bc they are still in the air fryer. So fingers crossed 🤞 and hoping to not waste no food. Be aware that not all air fryers are the same and they all don’t do the same Thing. Read the entire recipe BEFORE u start cutting up food. Bc God knows we don’t need to be wasting food. 🙏💯
    1. Hi, Julie! Wow, that sounds like quite a kitchen adventure. I'm sorry to hear you had trouble with the recipe, but that is a great point about using different air fryers. I just added a note to the recipe card about this. Thanks for pointing it out!
  3. Wow that Julie girl really knows what she’s talking about. 🤫👌🤨🤭😂👍💯👌✌️❤️
  4. How long will the onions stay crispy? Can I save them for later/multiple meals? Thanks I'm looking forward to trying out this recipe!
    1. Hi, Liv, we find they last about five days...if they don't all get eaten by then. You can always also just pop them back in the air-fryer or oven to warm them and re-crisp a bit.
  5. I made this the other night and they were great, but I did spray the batch with olive oil. I’m sure they would be sucky and dry/floury without? Hence Julies rant? Simple fix. yay or nay?
  6. Made these to go with an awesome white bean dip that used one of my bro’s home grown and smoked chipotle. Perfect seasoning! No basket fryer - I was lucky enough to have my oven replaced and purchased a Frigidaire double wall unit with built in air fryer (thank you home warranty - it has a bread proofing setting too!). Still getting used to it and I rather went to the side of over toasty! Notes have been made and 6 minutes is the timing for this model.
    1. Thanks for letting us know, Linda. (And others with that same model.) Also, I don't know which I'm more fascinated by: the oven with a bread proofing setting or homegrown, smoked chipotles!
  7. Just made these for a green bean casserole— absolutely incredible!! Thank you for coming up with and sharing this amazing recipe!! :)
