First, preheat the air fryer to 360 degrees Fahrenheit for 3 minutes.
Now, layer half of the frozen onion rings bag into the basket in a single layer. You need to make sure they are not layered on top of each other, or you will be left with uneven onion rings.
Lightly spray the onion rings with cooking oil for extra crispiness.
Next, cook the onion rings in the air fryer for 8 to 10 minutes at 400 degrees Fahrenheit. Open the basket and flip the onion rings with silicone-tipped tongs, halfway through the time. Continue cooking them until you get the desired crispiness.
Remove them from the basket and go for another batch of onion rings in the air fryer.
Once done, serve them with your favorite dipping sauce. Enjoy!
Notes
Do not stack onion rings in the air fryer basket. It can result in inconsistent taste and uneven texture, which may not be appealing in the end.
Please note that not all air fryers are the same. Hence, you may need to adjust the cooking time and temperature depending on your specific model. What I would suggest is that you go in multiple batches and it can give you an idea about what might work best for your air fryer.
Always spray non-stick cooking oil on the onion rings, as it will give you consistent texture and even taste. It will also help you with easy cleaning.
Adding a parchment paper will also help you with quick cleaning afterward. It usually catches the drip and juices from the bottom of the air fryer basket, leaving you with minimal work.
