    ⭐ Onions in Air Fryer Benefits

    Why make onions in the air fryer? Here are a few reasons for you:

    • Fast: You can sauté onions in the air fryer in only 12 minutes! Adding a few more minutes at a lower temp will give you a little caramelization. Caramelizing onions on the stovetop can take 45-60 minutes, so this is a huge time saver.
    • Hands off: Unlike when you cook onions on the stove, you only need to stir once when making air fried onions! Your hands will be free to make other parts of the meal.
    • Easy clean up: Sometimes food sticks to even non-stick skillets and seasoned cast iron. If you don’t like scrubbing pans, air frying is the way to go.
    • Special diets: This simple air fryer recipe is vegan, low carb, and gluten free. Just about everyone can eat air fryer onions!
    • Delicious: Did I mention how tasty these are? I could seriously eat these onions right off the air fryer tray.

    🥘 Air Fryer Onions Ingredients

    To make onions in an air fryer, you need the following ingredients:

    • One sweet onion (8 ounces/227 grams)
    • One tablespoon avocado oil (or your favorite cooking oil)
    • Salt (I prefer smoked salt)
    ingredients onions air fryer

    I’m keeping it simple with just salt for seasoning. However, mix things up with whatever seasonings you prefer. Italian seasoning, garlic powder, onion powder, black pepper, and Everything Bagel seasoning are some ideas to get you started.

    The one thing I’d avoid is seasoning blends with added sugar. Sugar will alter the cooking time of your onions, making them easier to burn.

    Speaking of cooking time, the amount of onions you use in this recipe is important. Using less onions will lead to a faster cooking time. You can use yellow onions or white onions, but I recommend sweet onions, as they caramelize the best.

    You’ll also want to have a good knife, a bowl, and an air fryer for this recipe. I use a 10-Quart Kalorik Digital Air Fryer Oven.

    The Ninja Foodi, Philips, Nuwave, Pampered Chef, Actifry, Instant Pot Vortex, Cosori, Breville, and other air fryers can air fry onions. Cooking times may need to be adjusted depending on the air fryer you use. Keep a close eye on the food whenever you try a new air fryer recipe for great results every time!

    🔪 How to Air Fry Onions

    We need to begin by slicing an onion. To slice onions, first cut off the blossom end and the stem end. Make a shallow cut in the onion from end to end and peel it.

    Cut the onion in half and then slice it into thin half-moons. You want the slices to be about ⅛-inch (0.3 cm) thick.

    Put the onions in a bowl, drizzle with oil, and sprinkle with salt. Spread the onions out in an air fryer basket or on an air fryer tray. As we sweat the onions, they’re going to shrink down, so no worries that they’re overlapping.

    If you have an air fryer oven, you should put the tray in the middle of the air fryer. Now it’s time to learn how to cook down onions!

    ️⏲️ Cooking Time and Temperature

    How long to cook onions in the air fryer? What temperature to air fry onions? Air fry onions for a total of 12 minutes at 350 degrees Fahrenheit (177C). Stir the onions after 10 minutes of cooking. This will give you lightly sauteed onions.

    air fryer sauteed onions

    For golden brown onions, next turn the air fryer heat down to 300F (149C) and air fry 5-10 minutes more. After 10 minutes, my caramelized onions were just starting to get crispy. You could make crispy onions by making the air frying time a little longer.

    Note that these aren’t just like the onions caramelized on the stove. The onions get crispy faster with the rapidly moving dry heat of the air fryer. Air frying isn’t the best method when you want to cook something over a long period and have it stay moist.

    ️🌡️ Leftovers

    Air fryer onions keep in a covered container in the refrigerator for up to 3-4 days. Note that leftover crispy onions may get soggy, so just make what you need.

    💭 Expert Tips from a Dietitian

    This is a level 1 recipe (may help support fat loss). I like to think of these as a healthier version of shoestring onions or crispy fried onions.

    Normally, crispy onions contain a lot of oil and often white flour. They can end up packing a lot of calories into a tiny portion. Crunchy fried onions from the store are what is called an ultra-processed food.

    This recipe is allergy-friendly because we’ve skipped the refined flour. However, like store crispy onions, most of the calories in this recipe actually come from oil. (Onions with no oil only provide 4 calories per tablespoon.)

    Luckily, you don’t need to follow an oil free diet to lose weight. People sometimes forget that the white vegetables (even if cooked in a little oil) count as healthy options too. Onions, like many veggies, provide phytonutrients that may benefit your health.

    Plus, onions are so flavorful! Aromatic onions are present in so many recipes because of the layer of flavor they add to foods.

    If you’re having trouble including enough veggies in your diet, why not start with onions? They’re nutritious, low calorie, inexpensive, widely available, and delicious!

    How to make a blooming onion air fryer recipe?

    I haven't tried it, but this air fryer blooming onion recipe from Stay Snatched looks amazing. If you have an extra sweet onion around, you may want to make it next!

    How to air fry onions with no oil?

    Though you can technically make air fryer onions without oil, they don’t tend to turn out well. The oil helps keep the onion from drying out too early and burning. Oil-free onions that are half burnt and half raw aren’t on anyone’s menu.

    How to cook a whole onion in the air fryer?

    I’ve seen recipes claiming you can cook a whole onion in the air fryer. However, some say the onion won’t get soft. Unless you’re cooking whole pearl onions, I’d stick to air frying chopped onions or sliced onions.

    How long can you store crispy fried onions without a freezer or fridge?

    Air fryer crispy fried onions should not be left out at room temperature for more than 2 hours. These onions have not had moisture removed as thoroughly as the ones from the store. This means they’re more likely to go bad if not refrigerated.

    How do you dehydrate onions in an air fryer?

    You can make air fryer dehydrated onions using the lowest temperature setting on your air fryer. Though they’ll take less time than using a food dehydrator, you’ll need to stir the onions far more often. Also, the air fryer can only dehydrate a very small batch of onions at a time.
