Why You’ll Love These Crispy Air Fryer Onion Rings
Whenever I’m planning party snacks or a game day menu, these air fryer onion rings usually make an appearance. They’re gluten-free (a given in this house) and made in the air fryer, which means they cook up crisp without the need for deep frying.
I used to love a classic deep-fried onion ring from a pub or diner, but most of those batters aren’t gluten-free. So I set out to make a version at home that hits the same nostalgic notes.
Sweet onions that are soaked, dipped in a seasoned batter, and cooked in the air fryer until crisp and golden on the outside, and nice and soft on the inside. Homemade onion rings are a fun twist on a diner classic that’s easy to enjoy right from your own kitchen.
What You’ll Need
Here’s everything you’ll need for the layers of coating that make these homemade onion rings the crispiest ever. Scroll down to the recipe card for the full amounts and step-by-step instructions.
- Onions: You’ll need 1-2 large onions. I recommend Vidalia or Maui, or another sweet onion when making onion rings.
- Milk & Greek Yogurt: I soak my onions in a mixture of whole milk and Plain Greek yogurt before starting to help the flour and breadcrumb coating stick. You can also use buttermilk if you prefer or if you have it on hand – I just use the combo of milk and yogurt because I always have those ingredients in my fridge and don’t always have buttermilk.
- Gluten-Free Flour: Either gluten-free all-purpose, or a 1-to-1 gluten-free flour blend like Bob’s Red Mill. Because it’s just a coating and not a baking recipe, the brand or type of flour is not critical.
- Eggs: For the egg wash layer.
- Gluten Free Breadcrumbs: Avoid gluten free Panko breadcrumbs as these are too large and don’t form a nice, even coating (of course, if you’re not making gluten-free onion rings, you can go ahead and use regular Panko because it’s not quite as large!).
- Cornmeal: Cornmeal is gluten free and fills in the texture and flavor of the gluten-free breading.
- Parmesan Cheese: Grated parmesan adds loads of extra flavor to the breadcrumb coating.
- Seasoning: I season the onion ring breading with a mix of smoked paprika, onion powder, garlic powder, Kosher salt, and black pepper.
- Oil: For cooking. Aim to use olive oil or another cooking oil in a mister bottle for spraying, versus a nonstick cooking spray (certain chemicals in cooking sprays like PAM can damage the finish on your air fryer).
How to Make Gluten-Free Onion Rings in the Air Fryer
- Soak the onions: While you assemble the other ingredients, place the onion slices in a mixture of milk and Greek yogurt and pop this into the fridge to soak.
- Create your dipping station: Pour your flour into a shallow dish. Beat the eggs together in a second shallow bowl. Finally, combine the breading ingredients in a third dish and set these out on your counter or workspace.
- Coat: One at a time, lift an onion ring from the milk mixture. Dip the ring into the flour, followed by the egg, and lastly the breadcrumbs. Repeat with the rest of the onions, placing the coated rings onto a baking sheet. Make sure your onion rings are laid out in a single layer, and give them a generous spray with cooking oil as your air fryer preheats.
- Air fry onion rings: Once the air fryer is ready, give the basket a spritz as well before carefully placing the onion rings into the fryer. Work in batches and cook the rings for about 5 minutes per side, until the breadcrumb coating is golden and crispy.
- Serve and enjoy: Keep your finished onion rings covered to keep them warm until you’re ready to serve them. Serve as a side, appetizer, or with any of your favorite dipping sauces – keep reading for ideas!
Onion Rings Air Fryer Tips
- Set Aside Half of the Breadcrumbs: One thing I’ve noticed is that, depending on the number of onion rings I’m dunking and dredging, the breadcrumb mixture can become sticky after a while. One trick to keep the coating fresh is to set aside a portion of the seasoned breadcrumbs, so you can swap them out if the first bowlful becomes overly clumpy.
- Fry in Batches: When it comes to air frying, batches are gospel – be sure to cook your onion rings in a single layer, with minimal touching for the best, crispiest results.
- Cooking Times May Vary: Not all air fryers are the same, so pay attention to the cooking time, keeping in mind that it may vary between models.
- Add Spice: If you’re after another layer of spice in your breadcrumb coating, try adding in cayenne pepper or chili powder for extra heat!
- Don’t Forget to Spray: Giving the onion rings a spritz with oil as you turn them over halfway through cooking will ensure that the outside gets extra crispy.
How to Store and Reheat Extras
- Refrigerator – Store your leftover onion rings airtight in the fridge for up to 3-4 days.
- Freezer – You can freeze the cooked onion rings for easy reheating. Wait until the onion rings are fully cool, and then flash-freeze them in a single layer before transferring them to a freezer bag. They will be best if eaten within two months.
- Reheat – The best way to reheat onion rings is to toss them back into the air fryer for a few minutes at 370ºF, or until they’re good and crispy again. If you’ve frozen them, there’s no need to thaw. They may just need an extra couple of minutes to get hot and crunchy again.
Frequently Asked Questions
What Kind of Onions Are Best for Onion Rings?
The best onions for onion rings are sweet varieties like Vidalia, Maui, Walla Walla or Texas onions. Sweet onions are flatter and lack the pungent flavor of some other types of onions.
Can I Use Frozen Onion Rings?
If you’d prefer to hit fast-forward on your onion ring craving, you can use your air fryer to cook ready-made frozen onion rings. BUT, these usually have gluten in the coating, so you may have to avoid the frozen ones unless you can find gluten free onion rings.
If you can enjoy frozen onion rings safely, the cooking time is about the same! Place the frozen onion rings in the fryer and cook them at 400ºF for 15 minutes or so.
Can You Freeze Homemade Onion Rings?
You can also freeze your own homemade onion rings to reheat in the air fryer – the details are above, but briefly, let them cool, then freeze in a single layer before transferring to a plastic freezer bag or airtight container for longer storage.
Reheat your frozen onion rings in the air fryer straight from frozen (as you would with any store-bought version), for homemade onion rings, anytime!
What Air Fryer Should I Use?
You’ll want an air fryer with a nice, large, and deep basket to fit lots of onion rings! So I recommend one that has at least a 5.8-6 Qt capacity. I like and use the Cosori brand, and have an older model of the Cosori 12-in-1 Air Fryer, but the Cosori 9-in-1 Turbo Blaze is a great option too.
Make It a Meal
Is there any meal that isn’t made better by pairing it with onion rings?
- With bar-style favorites. Onion rings are a classic pub food, and I love to serve these with other classics like Air Fryer Hamburgers and Homemade Air Fryer French Fries.
- With dips for dunking. They’re also an easy and satisfying snack or appetizer to dip into sauces like Honey BBQ Sauce, Gluten Free Cheese Sauce, Bang Bang Sauce, and my favorite: Big Mac Sauce!
- Fun family dinner. You can also make onion rings into a meal with kid-friendly Gluten Free Air Fryer Chicken Tenders and veggies like Air Fryer Roasted Carrots, Bacon Green Beans, or Crisp Tender Air Fryer Asparagus.

- ½ cup grated parmesan cheese
- ½ tsp Kosher salt
- ½ tsp smoked paprika

Instructions
- Slice the top and bottom off of 1-2 large sweet onions, remove the outer skin, then slice into rings about 1/2-inch thick.
- Stir¾ cup milk and ¼ cup plain Greek yogurt together in a large bowl. Add the onion slices and let them soak in the refrigerator for 30 minutes to 1 hour.

- Remove one onion ring from the milk mixture and let any excess drip off, then coat in flour. Dip in the egg, and then in the breadcrumb mixture. Place on a baking sheet.
- Repeat with the remaining onion rings, spreading them out in a single layer separated so they don’t stick together. Spray the tops of the onion rings thoroughly with oil in a mister bottle for spraying, or cooking spray. Flip and spray them again.
- Preheat the air fryer to 370°F. Once it is preheated, coat the basket with cooking spray. Place onion rings in a single layer in the air fryer basket, and cook in batches at 375°F for 5 minutes. Flip and spray again with oil, then cook until golden brown and crispy on both sides, for another 3-5 minutes. Cooking time can vary based on the size of your onion rings and the model of your air fryer. This recipe was tested using a Cosori XL 5.8 quart air fryer. Cover to keep warm while cooking the remaining onion rings.

Can i bake these in my oven instead of an air fryer. I don’t have an air fryer. If yes, what are the instructions.
I have not tried the oven. The air fryer had the convection feature that give it the result more like something that’s been fried.
