How To Reheat Onion Rings

Onion rings are the ultimate fast-food appetizer, as popular and ubiquitous on menus as French fries. It is one of the most popular sides to have with burgers and hot dogs and is a common feature on most American menus.

As much as I love onion rings, I have never brought home leftovers because I assumed they will be soggy and unappetizing. But I have discovered a number of great ways to revitalize onion rings that taste as good as new even days later. Whether store-bought or homemade, there are plenty of great options to choose from to reheat onion rings.

How To Reheat Onion Rings in the Oven

Heating onion rings in the oven is one of the best ways to give these delicious appetizers a fresh life. Onion rings heated using this method retain their crunch and texture.

1. Preheat the oven to 350 degrees F.
2. Place the onion rings on a lined baking tray.
3. Spritz a little oil on them. You can also add some flavoring if you want like garlic powder, paprika, Parmesan, or any other spice of your choice.
4. Place in the oven and heat the onion rings for 3-5 minutes.
5. Take out and dab with paper towels to remove any excess oil.
6. Serve immediately with your favorite dip.

The oven is the best way to reheat onion rings. The biggest upside is that the onions get heated evenly and retain their crunch without getting soft and soggy. The downside of course is that it is a little bit time-consuming, but the end result makes it worth the extra effort.

Quick tip: Do not cover the onion rings with foil in the oven as this makes them soggy.

How To Reheat Onion Rings in a Toaster Oven

This is another simple way to reheat onion rings, similar to the oven with minimal fuss and mess.

1. Preheat the oven to 350 degrees F.
2. Give the onion rings a quick blast in the microwave, just around 10 seconds, to get them warmed up.
3. Place the onions on a lined baking tray.
4. Heat the onions for 5 to 6 minutes.
5. Remove once it has become crisp and serve immediately.

The one thing to keep in mind is that while this is an easy way to reheat onion rings, it can be a hit or miss. There is a good chance to overcook them, but it is relatively mess-free and quick to make.

How To Reheat Onion Rings in the Microwave

This is the quickest way to reheat onion rings but also the least satisfying. But it is pretty straightforward and easy, and you can have hot onion rings in a jiffy.

As easy and quick as the microwave is, reheating onion rings in it is a huge failure. The biggest problem is that the onion rings come out hot but limp and soggy. The onion rings go from crisp and crunchy to lifeless and unappetizing. And as soon as the onion rings cool down, they get chewy.

The air fryer makes the onion rings nice and crunchy giving them a delightful crispness. It is definitely easier to use and prep than the oven and toaster oven with a crisper, crunchier result. Having said that, it is easy to burn the onion rings in the air fryer so watch out. You can keep checking in to see the texture and crispness.

How To Reheat Onion Rings in a Deep Fryer

This is another tried and tested method of reheating onion rings, while the results are fairly satisfying, there is a lot more oil and grease to deal with.

1. Heat up your deep fryer till the oil reaches a temperature of 350 degrees F.
2. Place the onion rings in the deep fryer basket and immerse them in the hot oil for 2-4 seconds.
3. Take the onion rings out and drain the excess oil and dab with paper towels.

Reheating onion rings in the deep fryer gives them a nice crunch and an appetizing dark golden-brown hue. Besides the obvious mess you get with using oil, the onion rings also tend to get extra oil if left even a second longer in the deep fryer. As the onion rings are already cooked, they just need a quick dip in the oil, so don’t let them soak in the oil. If left too long the onions shrivel up because of the heat and the onion rings get heavy and soggy instead of light and crispy.

How To Reheat Onion Rings in a Skillet

This is another quick way to refresh cold onion rings that makes them warm and crispy.

3. Then flip them over and heat them on the other side.
4. Take off heat and dab with a paper towel to remove excess oil.
5. Serve hot.

Reheating onion rings in the skillet is not only quick and easy but also maintains the taste and texture of the onion rings. Don’t be heavy-handed with the oil, or else you may end up with dense, and soggy onion rings. The right amount of oil gives the onion rings just some extra crispness and color. Also, the onion rings need to be flipped else you will end up with one side burnt. Also, if you heat on high flame the onion rings stick to the pan and start burning, so keep an eye out.
