Preheat the air fryer to 350°F
Preheating your air fryer is a crucial step in the cooking process. By preheating your air fryer to 350°F, you ensure that your onion rings cook evenly. This is especially important when cooking frozen foods. Preheating your air fryer also helps to reduce the overall cooking time and promotes the development of a crispy texture.
To preheat your air fryer to 350°F, start by turning on your air fryer and setting the desired temperature. Allow the air fryer to heat up for a few minutes until it reaches 350°F. Most air fryers will have a temperature indicator light or a digital display that will notify you when the desired temperature is reached. Refer to your air fryer's user manual for specific instructions regarding preheating and temperature settings.
While the air fryer is preheating, you can prepare your onion rings. Peel and slice the onions into 2-inch rounds, then separate them to create individual onion rings. It is important to ensure that the onion rings are in a single layer, without overlapping, to promote even cooking. If you are using frozen onion rings, simply take them out of the freezer and have them ready for cooking.
Once your air fryer reaches 350°F, you can carefully place the onion rings into the air fryer basket. Depending on the size of your air fryer, you may need to cook the onion rings in batches to avoid overcrowding. Lightly spray the onion rings with cooking spray or your preferred oil spray to enhance crispness and prevent sticking.
By preheating your air fryer to 350°F, you create the ideal environment for cooking onion rings. This temperature allows the onion rings to cook thoroughly and attain the desired crispness. Remember to refer to your specific air fryer's instructions for preheating guidelines and always exercise caution when handling hot appliances.

Use frozen onion rings
Cooking frozen onion rings in an air fryer is a quick and easy way to get crispy and delicious onion rings. It is much quicker than baking them in the oven and is also healthier than deep-frying.
To cook frozen onion rings in an air fryer, start by preheating your air fryer. Preheating allows your air fryer to cook more evenly. Set your air fryer to its highest temperature setting, between 400 and 450 degrees Fahrenheit, and preheat for 2 to 3 minutes.
Once preheated, place your desired amount of frozen onion rings into the air fryer basket. Make sure not to overcrowd the basket, as this will prevent the onion rings from cooking evenly and may cause them to stick together. Layer the onion rings in a single layer, with minimal overlap. For best results, spray the onion rings with a light coating of vegetable, olive, or avocado oil using an oil mister or EVO Oil Sprayer. This will help to enhance the crispiness of the onion rings.
Close the air fryer and cook the onion rings for 8 to 12 minutes at a temperature between 350 and 400 degrees Fahrenheit. For lower temperatures, consider cooking for a longer duration, and vice versa. Shake or flip the onion rings halfway through the cooking process to ensure even cooking and browning.
Once the onion rings have reached your desired level of crispness, remove them from the air fryer and serve immediately. Enjoy your crispy, golden-brown onion rings as a side dish or appetizer!

Bread the onion rings
To bread the onion rings, you'll need to first slice the onions into 1/2-inch-thick slices and separate them into rings. Next, you'll need to prepare three separate mixtures: flour, egg, and breadcrumbs. The flour can be combined with seasonings like garlic powder, onion powder, salt, cayenne, pepper, and seasoning salt. The egg can be whisked with a bit of milk. For the breadcrumbs, panko crumbs are recommended for a crispy texture.
Now, you're ready to start breading the onion rings. Dip each onion ring first into the flour, ensuring it's fully coated. Then, dip it into the egg mixture, followed by another dip into the flour. Finally, dip the onion ring back into the egg mixture and then coat it with the breadcrumb mixture. Repeat this process for all the onion rings, placing them on a tray in a single layer as you go.
Some recipes suggest double-dipping the onion rings in the flour and egg mixtures for an extra-thick coating. You can also freeze the onion rings for about 10 minutes after flouring them to help the egg wash adhere better. If you want a lighter coating, you can skip the second dip in the flour and egg mixtures.
Once all your onion rings are breaded, they're ready to be cooked in the air fryer!
