What You'll Learn

Preheat settings
If you choose to preheat your air fryer, the recommended temperature is 350 degrees Fahrenheit. This temperature is lower than the typical oven temperature for baking frozen onion rings, which is usually around 400 to 425 degrees Fahrenheit. By preheating at 350 degrees, you can avoid overheating and potentially burning the onion rings.
The duration for preheating your air fryer is typically around 3 minutes. This brief preheating time ensures that your onion rings cook evenly without spending too much time in the appliance. After preheating, you can proceed to place the frozen onion rings inside and adjust the temperature and timing according to your desired level of crispiness.
It is worth noting that different air fryer brands may have varying cooking times and temperatures. Therefore, it is always a good idea to refer to the specific instructions provided by the manufacturer of your air fryer. Additionally, the type of onion rings you choose, such as panko-crusted or battered, can also impact the ideal cooking temperature and duration. Panko-crusted onion rings, for example, tend to crisp up faster and may require a slightly lower temperature to avoid burning.

Cooking time and temperature
The cooking time and temperature for air fryer frozen onion rings can vary depending on the brand of onion rings and the model of the air fryer. It is recommended to follow the instructions on the packaging of the onion rings, adjusting the temperature and time as needed. Generally, it is advised to cook frozen foods at a slightly lower temperature than what is recommended for oven baking. For example, if the package recommends baking at 425 degrees Fahrenheit, the temperature can be reduced to 400 degrees Fahrenheit for the air fryer.
Some sources suggest preheating the air fryer to 350 degrees Fahrenheit for about 3 minutes before placing the onion rings in the basket. The onion rings should be spread out in a single layer, ensuring they do not overlap, and cooked for about 3 minutes. Then, flip the onion rings and continue cooking for another 3 minutes. For crispier onion rings, the temperature can be increased to 390 degrees Fahrenheit, and cooked for an additional 1-2 minutes.
Alternatively, some sources recommend cooking the onion rings at 400 degrees Fahrenheit for 8-10 minutes. Halfway through the cooking process, open the basket and flip the onion rings, continuing to cook until the desired crispness is achieved.
For those who prefer not to preheat their air fryer, the onion rings can be cooked at 400 degrees Fahrenheit for 5 minutes, moved around, and then cooked for an additional 5 minutes. This process can be repeated, cooking in 5-minute increments, for a total of 15 minutes or until the desired crispness is achieved.
It is important to note that cooking times may vary depending on the specific air fryer model, so adjustments may be necessary. Additionally, it is recommended to shake or stir the onion rings periodically during the cooking process to ensure even cooking.

Flipping and shaking
Flipping the Onion Rings:
- Halfway through the cooking process, open the air fryer basket.
- Use tongs to carefully flip each onion ring. This ensures that both sides of the onion rings cook evenly and get crispy.
- After flipping, continue cooking until the onion rings reach your desired level of crispness.
Shaking the Basket:
- In addition to flipping, it's recommended to shake the air fryer basket during cooking.
- To shake the basket, simply remove it from the air fryer and hold it firmly by the handle.
- Gently toss or stir the onion rings inside the basket to ensure they are evenly distributed and not stuck together.
- For optimal results, shake the basket every 3 minutes or halfway through the cooking time.
By combining flipping and shaking techniques, you can ensure that your frozen onion rings cook evenly and achieve a delicious, crispy texture. Remember to adjust the cooking time and temperature according to your specific air fryer model and your personal preferences for crispness.

Oil and non-stick spray
While cooking frozen onion rings in an air fryer, you can use oil or non-stick spray to make them crispier.
Oil
If you want to use oil, you can spray the onion rings with vegetable or olive oil using an EVO oil sprayer. You can use this at the beginning or in the middle of the cooking process. However, it is important to note that most frozen foods in the US already have oil cooked into them, so you may not need to add any extra oil.
Non-stick spray
If you prefer not to use oil, you can use a non-stick cooking spray on the onion rings. This will give them extra crispiness without the need for added oil. Simply spray the inside of the air fryer basket with the non-stick spray and then pour in the onion rings, spreading them out so they aren't piled on top of each other.
It is recommended to preheat your air fryer to ensure even cooking, especially when cooking from frozen. Preheat your air fryer to 350 degrees Fahrenheit for about 3 minutes. Then, place your desired amount of onion rings into the basket, spreading them out evenly.
Cooking times may vary depending on your air fryer and the desired crispness of your onion rings. A general guideline is to cook the onion rings for 8-12 minutes at 350-400 degrees Fahrenheit, flipping them halfway through the cooking process. For crispier onion rings, you can increase the temperature to 390-400 degrees Fahrenheit and cook for an additional 1-2 minutes.
So, whether you choose to use oil or non-stick spray, you can easily cook delicious and crispy frozen onion rings in your air fryer!

Reheating and storing
Leftover onion rings should be stored in an airtight container in the refrigerator. To reheat, place them in the air fryer at 400°F for 3-5 minutes. Shake or stir the onion rings, then cook for an additional 2-3 minutes or until warmed through. Reheating at a lower temperature ensures the onion rings get crispy without burning.
Alternatively, you can reheat frozen onion rings in the air fryer without defrosting them first. Preheat the air fryer to 350°F for about 3 minutes. Place the frozen onion rings in the air fryer basket and spread them out evenly. Air fry for approximately 3 minutes, then flip the onion rings and continue to air fry for another 3 minutes. For crispier onion rings, increase the temperature to 390°F and air fry for an additional 1-2 minutes.
It's important to note that the cooking time may vary depending on the brand of onion rings and the specific model of your air fryer. Some sources suggest cooking frozen onion rings at 400°F for 8-10 minutes, flipping them halfway through, and adjusting the cooking time based on your desired level of crispness. Others recommend cooking in 5-minute increments, stirring after each increment, and adjusting the cooking time as needed.
