A Flavorful Solution: Reheat Onion Rings to Perfection in an Air Fryer

How to Reheat Onion Rings in Air Fryer: A Complete Guide


Onion rings are a delicious snack that can sometimes lose their crispiness when reheated. Fortunately, with the help of an air fryer, you can easily revive the crispy texture and delightful taste of your leftover onion rings. In this guide, we will walk you through step-by-step instructions on how to reheat onion rings in an air fryer.

Why Use an Air Fryer?

Using an air fryer is not only convenient but also ensures that your onion rings remain crispy without excess oil or grease. The hot circulating air inside the appliance helps retain the original crunch while evenly reheating them from all sides.

The Step-by-Step Process:

Step 1: Preheat Your Air Fryer

Before starting, it’s important to preheat your air fryer for optimal results. Set the temperature between 350°F (175°C) and 400°F (200°C) depending on your preference and allow it to heat up for about five minutes.

Step 2: Arrange Onion Rings

While waiting for your air fryer to preheat, take out your leftover onion rings from the refrigerator or freezer. Lay them out in a single layer on a wire rack or directly in the basket of the air fryer.

Step 3: Spritz Some Oil (Optional)

To enhance crispiness, lightly spritz some cooking oil onto both sides of each onion ring using a cooking spray bottle if desired. This step is optional as onions already contain natural moisture which aids in retaining some level of crispness during reheating.


Olive oil or vegetable oil spray works well.
– Avoid saturating the onion rings with oil, as this may lead to a greasy outcome.

Step 4: Reheat in the Air Fryer

Place the wire rack or basket with the onion rings into the preheated air fryer. Allow them to cook for approximately three to five minutes, depending on their initial temperature and desired level of crispness.


– For already thawed onion rings, aim for three minutes.
– If reheating frozen onion rings, increase the time to five minutes or until they reach your preferred level of crunchiness.

Step 5: Shake and Flip

After a couple of minutes in the air fryer, pause and carefully shake or flip each onion ring using tongs. This helps ensure even reheating and prevents any side from becoming overly crispy.

Step 6: Continue Reheating (If Needed)

If you feel that your onion rings require additional crisping, simply continue cooking them in one-minute intervals until achieving your desired texture. Keep an eye on them during this process to prevent burning.

Tips for Serving Reheated Onion Rings

1. Serve Immediately

Once fully reheated, remove the onion rings from the air fryer immediately. Enjoying them while they are still hot ensures maximum taste and crunchiness.

2. Pair with Dipping Sauces

Enhance your dining experience by serving freshly reheated onion rings alongside various dipping sauces such as ketchup, spicy mayo, ranch dressing, or chipotle sauce. These condiments complement perfectly with their crispy exterior and savory flavor.

In Conclusion

Reheating leftover onion rings in an air fryer is a fantastic way to revive their deliciousness without sacrificing their original crispy texture. By following the step-by-step process outlined in this guide, you can enjoy piping hot and perfectly crispy onion rings anytime. So, don’t let those leftovers go to waste – fire up your air fryer and indulge in this delightful snack!
