Cook Air Fryer Onion Rings (Homemade) Like This

Step 1: Prepare the Onion
Start by peeling the large sweet onion. Cut it into thick slices, about ½ inch wide, and then separate the slices into rings. Aim for uniformity to ensure even cooking.
Step 2: Soak in Buttermilk
In a mixing bowl, pour the 3 cups of buttermilk over the onion rings, ensuring they are fully submerged. Let them soak for at least 30 minutes. This step is crucial as it tenderizes the onions and enhances their flavor.
Step 3: Make the Coating
In another mixing bowl, combine the 1 cup of breadcrumbs, ½ cup of cornmeal, ½ cup of flour, and 2 tablespoons of Cajun seasoning. Mix well until everything is evenly distributed.
Step 4: Prepare the Egg Whites
In a separate bowl, whisk the ¼ cup of egg whites until slightly frothy. This will help the coating adhere to the onion rings.
Step 5: Dredge the Onion Rings
Remove the soaked onion rings from the buttermilk and let the excess drip off. Dip each ring first into the egg whites, ensuring it’s coated, then dredge it in the breadcrumb mixture, pressing lightly to adhere. Repeat this for all onion rings.
Step 6: Preheat the Air Fryer
Preheat your air fryer to 375°F (190°C) for about 5 minutes. This ensures that the onion rings begin to cook immediately, resulting in a crispier finish.
Step 7: Air Fry the Onion Rings
Spray the air fryer basket with oil spray to prevent sticking. Arrange the onion rings in a single layer, making sure they don’t overlap. Lightly spray the tops with oil. Cook for 10-12 minutes or until golden brown and crispy, flipping them halfway through the cooking time for even crisping.
Step 8: Serve and Enjoy!
Once cooked, carefully remove the onion rings from the air fryer. Serve them hot with your favorite dipping sauces—think ranch, ketchup, or spicy aioli. Enjoy your homemade crispy goodness!
Substitutions by Diet

- Gluten-Free: Use gluten-free breadcrumbs and flour.
- Dairy-Free: Substitute buttermilk with a non-dairy milk mixed with a tablespoon of vinegar or lemon juice.
- Lower Carb: Use almond flour instead of all-purpose flour and omit breadcrumbs.
- Spice Level: Adjust the Cajun seasoning to your preference or use a mild seasoning blend for a less spicy option.
Insider Tips
- For the crispiest onion rings, make sure they are not overcrowded in the air fryer basket. Cook in batches if necessary.
- Letting the onion rings rest for a few minutes after frying will enhance their crunchiness.
- Experiment with different seasonings to find your perfect flavor combination—garlic powder and smoked paprika can be great additions!
- For added flavor, marinate the onion rings in buttermilk overnight for an even richer taste.
Keep It Fresh: Storage Guide
These Air Fryer Onion Rings (Homemade) are best enjoyed fresh. However, if you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. To reheat, place them back in the air fryer at 350°F (175°C) for about 5 minutes to regain their crispiness. Avoid reheating in the microwave, as they may become soggy.
Popular Questions
Can I make these onion rings ahead of time?
Yes! You can prepare the onion rings up to the point of air frying. Assemble and coat them, then store them in the fridge for a few hours or overnight before cooking.
What other vegetables can I use in the air fryer?
Feel free to try other vegetables like zucchini, eggplant, or even mushrooms! Just adjust the cooking time as needed based on the thickness of the slices.
How do I know when the onion rings are done?
The onion rings are done when they are golden brown and crispy. Keep an eye on them, as cooking times may vary between different air fryer models.
Can I freeze the onion rings?
Yes, you can freeze them before cooking. Place the coated onion rings on a baking sheet in a single layer and freeze until solid. Once frozen, transfer them to a freezer bag. When ready to cook, air fry them straight from frozen, adding a couple of extra minutes to the cooking time.
