Start by preheating your air fryer to 375°F (190°C). This step ensures that the onion rings cook evenly and become wonderfully crispy.
While the air fryer is preheating, take your frozen onion rings and arrange them in a single layer in the air fryer basket. Make sure they are not overlapping to allow proper air circulation.
For that extra crispy texture, lightly spray the onion rings with cooking spray or use a pastry brush to apply a thin coat of oil. This step helps in achieving that golden crunch.
Slide the basket into the preheated air fryer and set the cooking time to about 8-10 minutes. Cooking times may vary slightly depending on your air fryer model, so keep an eye on them.
About halfway through the cooking time, pause the air fryer and carefully flip the onion rings. This ensures that both sides cook evenly and become crispy.
Keep an eye on the onion rings as they cook. When they turn a beautiful golden brown and appear crispy, they're ready to be enjoyed.
Once your frozen onion rings are perfectly crispy, remove them from the air fryer basket, and let them cool for a minute. Then, serve them hot with your favorite dipping sauces.
