Crispy Air Fryer Onion Rings

Create crispy, flavorful onion rings that are a healthier alternative to deep frying with this easy recipe for Air Fryer Onion Rings. Thick, sweet onions are dipped in buttermilk, double-dredged in flour and egg, and coated with panko breadcrumbs for a light, crunchy finish. These homemade onion rings make a perfect side for burgers or a crowd-pleasing game-day appetizer.

Years ago I worked at a local Sonic in my hometown in Oklahoma, where one of the chores was hand-breading onion rings. Sitting in the back doing that tedious work taught me the best technique for coating onions evenly. I now use that same method to make a lighter version in the air fryer. The result is golden, crisp onion rings with much less oil than the fried version—without sacrificing texture or flavor.

Ingredients

• Sweet onion – choose a large Vidalia or Walla Walla for the most tender, mildly sweet rings.
• All-purpose flour – for the dry dredge.
• Cornstarch – helps the coating adhere and adds extra crispiness.
• Seasoned salt and garlic powder – for flavoring the flour mix.
• Eggs – combined with buttermilk for the wet dip.
• Buttermilk – its thickness and mild acidity help the coating cling and improve flavor.
• Panko breadcrumbs – gives a light, crunchy exterior; substitute gluten-free panko if needed.

1. Slice the onion: Peel and slice your onion into ½-inch thick rounds, then separate into individual rings.
2. Set up a breading station: In one shallow bowl combine the flour, cornstarch, 1 teaspoon seasoned salt and garlic powder. In a second bowl whisk the eggs with the buttermilk. In a third bowl place the panko breadcrumbs and season with the remaining teaspoon of seasoned salt.
3. Bread the onion rings: Dip each ring first into the egg-and-buttermilk mixture, then dredge in the flour mix, return it to the egg mixture, and finally coat with panko. Press gently so the panko adheres well. Continue until all rings are coated.
4. Preheat your air fryer: Heat to 350°F (175°C).
5. Air fry: Arrange the rings in a single layer in the air fryer basket with a bit of space around each ring to allow air circulation. Spray lightly with cooking oil spray. Cook 12–15 minutes, until the coating is golden and crisp. There’s no need to flip; flipping risks knocking off the breading.

Recipe tips

• Cook in batches: You’ll likely need 2–3 batches depending on the size of your air fryer. Keep finished rings on a wire rack while the others cook—this preserves crispness.
• Use one hand for wet, one hand for dry: When breading, this prevents clumping and keeps the breading station tidy.
• Smaller rings can go inside larger ones: It’s fine to nest smaller rings in the center of larger ones as long as air can still circulate between pieces.
• Gluten-free option: Substitute a gluten-free flour blend or rice flour and use gluten-free panko breadcrumbs.
• Flavor variations: Swap the seasoned salt for ranch seasoning, fry seasoning, or a touch of Cajun seasoning for a spicier kick.

How to make them in the oven

If you don’t have an air fryer, use your oven. Preheat to 425°F (220°C). Place the battered onion rings on a wire rack over a foil-lined baking sheet, spray lightly with cooking oil, and bake 15–18 minutes or until golden and crisp. If your oven has a convection setting, use it for the best crisping.

Storage and reheating

This recipe yields about 18 onion rings. Store uncooked, breaded rings in a freezer-safe container for up to 3 months. Cook them from frozen in the air fryer at 350°F, adding about 2 minutes to the cook time (approximately 14–17 minutes total).

Leftover cooked rings keep in an airtight container in the refrigerator for up to 5 days. Reheat in the air fryer at 400°F for 2–3 minutes to restore crispiness.

Tools for this recipe

• Air fryer (at least a medium-size basket)
• Wire cooling rack and baking sheet
• Three shallow bowls for the breading station
• Kitchen tongs or a slotted spatula
• Cooking oil spray

What to serve them with

These onion rings work well as an appetizer with dipping sauces like ketchup, barbecue sauce, ranch, chipotle mayo, or a creamy burger sauce. They’re also an ideal side for burgers, fried chicken, pulled pork sandwiches, and other casual mains.
