Crispy and flavorful, air-fried onion rings are a delightful snack or side dish that can be made with ease. Using an air fryer ensures that you get that perfect crunch without the excess oil, making it a healthier alternative to traditional deep-fried onion rings.
If you don't usually keep buttermilk in your fridge, you might need to pick some up at the supermarket. It's essential for giving the onion rings their tangy flavor and tender texture. Additionally, make sure you have breadcrumbs on hand, as they provide the necessary crunch.

Ingredients For Air Fried Onion Rings Recipe
Onions: Large onions are sliced into rings to form the base of the recipe.
All-purpose flour: Used to create the initial coating for the onion rings.
Baking powder: Helps the coating puff up slightly for a better texture.
Salt: Enhances the overall flavor of the onion rings.
Buttermilk: Adds tanginess and helps the coating adhere to the onions.
Breadcrumbs: Provides the crispy outer layer for the onion rings.
Paprika: Adds a mild spice and color to the coating.
Garlic powder: Infuses the coating with a savory garlic flavor.
Technique Tip for This Recipe
When coating the onion rings, ensure that you press the breadcrumbs mixture firmly onto the rings. This helps create a thicker, more even crust that will crisp up beautifully in the air fryer. Additionally, using panko breadcrumbs instead of regular breadcrumbs can yield an even crunchier texture.
Suggested Side Dishes
Alternative Ingredients
large onions - Substitute with shallots: Shallots have a milder and sweeter flavor, which can provide a different but pleasant taste for the onion rings.
all-purpose flour - Substitute with whole wheat flour: Whole wheat flour adds a nutty flavor and more fiber, making the onion rings slightly healthier.
baking powder - Substitute with baking soda: Use half the amount of baking soda as a substitute for baking powder, but add an acidic ingredient like vinegar or lemon juice to activate it.
salt - Substitute with soy sauce: Soy sauce can add a deeper umami flavor along with the saltiness, enhancing the overall taste of the onion rings.
buttermilk - Substitute with plain yogurt: Plain yogurt provides a similar tangy flavor and creamy texture, making it a good alternative to buttermilk.
breadcrumbs - Substitute with panko breadcrumbs: Panko breadcrumbs are lighter and crispier, which can give the onion rings a better crunch.
paprika - Substitute with cayenne pepper: Cayenne pepper adds a bit more heat and a similar smoky flavor, making it a good substitute for paprika.
garlic powder - Substitute with onion powder: Onion powder provides a similar depth of flavor and can complement the onion rings well.

How to Store or Freeze Your Onion Rings
Allow the onion rings to cool completely before storing. This prevents condensation, which can make them soggy.
Place the cooled onion rings in an airtight container. If stacking them, use parchment paper between layers to maintain their crispiness.
Store the container in the refrigerator for up to 3 days. Reheat in the air fryer at 375°F (190°C) for 3-5 minutes to restore their crunch.
For freezing, arrange the cooled onion rings on a baking sheet in a single layer. Freeze for 1-2 hours until solid.
Transfer the frozen onion rings to a freezer-safe bag or container. Label with the date and store for up to 2 months.
When ready to enjoy, reheat the frozen onion rings directly in the air fryer at 375°F (190°C) for 10-12 minutes, flipping halfway through, until heated through and crispy.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover onion rings on a baking sheet lined with parchment paper. Bake for 10-15 minutes, flipping halfway through, until they are heated through and crispy.
Use an air fryer to reheat the onion rings. Preheat the air fryer to 375°F (190°C). Arrange the rings in a single layer in the basket and cook for 3-5 minutes, shaking the basket halfway through to ensure even heating.
For a quick microwave method, place the onion rings on a microwave-safe plate lined with a paper towel. Microwave on high for 20-30 seconds. Note that this method may not retain the crispiness as well as the oven or air fryer.
If you have a toaster oven, preheat it to 350°F (175°C). Place the onion rings on the toaster oven tray and heat for 5-7 minutes, flipping halfway through, until they are hot and crispy.
For stovetop reheating, heat a non-stick skillet over medium heat. Add a small amount of olive oil or butter to the pan. Place the onion rings in the skillet and cook for 2-3 minutes on each side until they are heated through and crispy.
