How to Reheat Onion Rings in an Air Fryer

Reheating onion rings in an air fryer is an excellent way to restore their crispy, crunchy texture that can often be lost when reheated by other methods. The air fryer uses circulating hot air to evenly reheat and crisp up the onion rings without making them soggy or oily. Here’s the best way to bring back the freshness of leftover onion rings using an air fryer:

Instructions for Reheating Onion Rings

1. Preheat the Air Fryer

  • Start by preheating your air fryer to 350°F (about 175°C). Preheating helps to ensure that the onion rings will reheat evenly and become crispy more quickly.

2. Arrange the Onion Rings

  • Place the onion rings in the air fryer basket in a single layer. Ensure they are not overlapping to allow for optimal air circulation around each onion ring. This is key to achieving an even crispness. If you have a large number of onion rings, it may be necessary to reheat them in batches.

3. Reheat

  • Cook the onion rings for about 3-4 minutes. Given that air fryer models can vary in their heating elements and fan strength, it’s a good idea to check on the onion rings halfway through the reheating process.

4. Check for Crispiness

  • After the initial reheating time, check the onion rings for your desired level of crispiness. If they aren’t crispy enough, you can continue to reheat them in 1-minute increments, checking after each minute to avoid overcooking.

5. Serve Immediately

  • Once the onion rings have reached the perfect level of crispiness, carefully remove them from the air fryer and serve immediately. They are best enjoyed hot and crispy.

Tips for Best Results

  • Avoid Crowding: Crowding the air fryer basket can lead to uneven reheating and less crispy onion rings. It’s better to work in batches than to try to fit too many in at once.
  • Shaking the Basket: Gently shaking the basket halfway through the reheating process can help ensure the onion rings reheat evenly on all sides.
  • Adjusting Time as Needed: Depending on the thickness of the onion rings and your specific air fryer model, you might need to adjust the reheating time slightly. Start with less time and add more as needed.


Using an air fryer to reheat onion rings is a quick and effective method to enjoy this favorite snack as if it were freshly made. By following these simple steps, you ensure your onion rings are crispy on the outside and tender on the inside, making for a delightful treat any time you have leftovers.
