Air Fryer frozen onion rings are a quick and easy side dish or appetizer. Cooking frozen onion rings in the air fryer is much quicker and the onion rings turn out much crispier than baking them in the oven. Air fried frozen onion rings are also healthier than those cooked in a deep fryer.

I’m a huge fan of onion rings, but I don’t have the patience to make homemade onion rings. This is where frozen onion rings have come to the rescue.
I occasionally deep-fry onion rings but I generally prefer to bake them in the oven. But I discovered that air fryer frozen onion rings get crispier than baked ones.
Onion rings make for a great appetizer or they can be served as a side dish for hot dogs and hamburgers. I think they turn out even better than fast-food restaurant onion rings.
I’ve been busy trying out different foods in the air fryer and I’ve found that the air fryer is excellent for reheating frozen foods.
Tips for Success
For this recipe, I recommend that you preheat your air fryer. My Cosori has a preheat button that allows me to preheat the air fryer before putting in the food.
Don’t defrost the onion rings. Cook them straight from frozen.
I do cook many frozen foods at 400 degrees F but I like to use a lower temperature for these onion rings so they cook evenly. I’ve found that cooking them at high temperature results in an overcooked exterior and undercooked interior.
Keep the air fryer onion rings frozen until you’re ready to cook them.
Don’t fill the air fryer basket too high because the onions may not cook through. I find that I can fit half a bag of frozen onion rings at a time in my air fryer without crowding the onion rings.
I have a few different sizes of air fryers and find that some of them can fit more than others.
If you have one of those smaller air fryers, you may need to air fry the onion rings in a few batches. You can reheat the prior batches for 1-2 minutes at 350 degrees Fahrenheit if they cool down too much.
Every air fryer will vary. The first time you make frozen onion rings inside the air fryer, monitor and check on them 2 minutes before the cooking time is up. Adjust the recipe as needed in the future.
I’ve done it with and without oil. The air fried frozen onions get crispy even without oil but you can spray a little oil (olive oil, avocado oil, or vegetable oil) on the onion rings and the bottom of the basket to make the onion rings even crispier. Don’t use canned cooking spray but rather an oil mister.
Keep the onion rings as close to a single layer as you can in order to get perfectly crispy onion rings. There can be a bit of overlap.
Cook them for about 12 minutes at 350 degrees Fahrenheit, shaking them halfway through. Check on them about 10 minutes in, and take them out if you feel that they’re done.
Nathan’s frozen onion rings is my favorite brand. I find they are the best frozen onion rings for the air fryer. My next favorite brand of onion rings is Alexia onion rings. Other popular brands are Red Robin, and Ore Ida onion rings.
If they aren’t crisp enough, toss the onion rings and air fry them for an additional 2 to 3 minutes.
Store leftover onion rings in an airtight container. Reheat onion rings in the air fryer is easy. Air fry them for 2 minutes at 350 degrees Fahrenheit. You may need to spray the onion rings with a little bit of oil if you find that they’re not getting crisp enough.
