Can You Reheat Onion Rings?

Yes, you can! If done right, your onion rings will taste just as good!

Although onion rings are best served fresh out of the fryer, people have found ways to preserve their texture and taste through various reheating processes. You can re-fry them, put them in the oven, use an air fryer, or even a microwave!

How to Reheat Onion Rings – The Best Way

Although there are many ways you could reheat your onion rings, this one ranks best. Using a toaster oven/convection oven to reheat your onion rings will help you get the most out of your rings without affecting their taste. 

To reheat your onion rings in the oven, follow these simple steps:

  1. Preheat your oven to 350 degrees Fahrenheit.
  2. Wrap your onion rings in aluminum foil and place them on the baking sheet.
  3. Add some oil, garlic by=utter, or seasonings of your choice.
  4. Heat for 10-15 minutes, or until they’re nice and crispy.
  5. Serve your onion rings warm!

If using a toaster oven:

  1. First heat your onion rings in the microwave to get them warm. 10-30 seconds should do the trick.
  2. Pop your warm onion rings in the toaster oven at 350 degrees Fahrenheit, and heat for 5-6 minutes. Brush them with little oil if necessary.
  3. Your onion rings should be nice and crispy!

How to Reheat Onion Rings Using A Skillet

Using a pan or a skillet to reheat your onion rings is a great option for when you need that extra crunch. It also saves you a lot of time, and is extremely convenient! 

To heat reheat your onion rings in a pan:

  1. Firstly, add some oil to your pan. You can even choose to add your preferred seasonings or flavor in the oil to make it extra tasty!
  2. Check to see if your oil is hot, and then add your onion rings to it.
  3. Make sure you maintain the flame at medium-low. Since your onion rings have already been fried once, reheating them on high will burn them.
  4. Flip them halfway through.
  5. Once they’re done, take them out on a paper towel to drain excess oil, and serve hot!

Pro Tip- Do not add too much oil to the pan. We do not want to deep fry them. A tablespoon or two should do the trick!

How to Reheat Onion Rings Using An AirFryer

Air fryers are still relatively new in people’s list of appliances that are convenient for reheating food. Most people are barely aware of just how useful Air Fryers can be when it comes to reheating food.

So can you reheat onion rings using an air fryer? Absolutely! They turn out amazing too!

If you follow the next few steps right, you should have warm, crunchy, and delicious onion fries at your disposal every single time!

  2. Next, coat your onion rings with cooking spray on all sides. This will ensure even reheating and a crispy texture.
  3. Reheat at about 375 degrees Fahrenheit for 10-12 minutes. 
  4. Make sure you flip them halfway to avoid burning them.
  5. Your onion rings are ready to eat!

How to Reheat Onion Rings Using A Microwave

Can you reheat onion rings in the microwave? Yes. Should you? Nope. 

Yes, I know that microwaves have become our go-to appliance when it comes to reheating food. And it does wonders with some food items. But onion rings aren’t one of them!

Think about this for a moment. Crispy, golden edges. The sound they make when you break them apart. Soft, flavourful, juicy battered onion rings on the inside. That is the perfect vision of an onion ring, isn’t it?

But if you get them anywhere near a microwave, think of a sloppy, soggy mess that will fall apart in front of your eyes. THAT is what the microwave will do to your onion rings!

But what if you don’t have the time to properly heat your onion rings? Is there a way to use the microwave without completely ruining your onion rings? Well, yes.

I would still recommend you to turn to the microwave as your very last option. But when you do, follow this simple trick. Place a glass of water along with your onion rings in the microwave. Heat for 2-3 minutes. You’re done!

If the rings turn soggy, sear them on a pan for another minute. That should fix it!

Can You Reheat Frozen Onion Rings?

Yes! Onion rings are one of the few fried items that can be fried/baked ahead of time and flash-frozen individually. The next time you need them again, you can simply reheat them directly instead of having to thaw them!      

You can either freeze raw onion rings or partially fry them and re-fry them later! Anything works as long as you’re doing it right. This recipe by Food. also provides freezing instructions on how to prepare and store your onion rings ahead of time!

If you’re going to be reheating your frozen onion rings in the oven, simply place them on the baking sheet and rehat for 4-5 minutes more than you normally would. You can even use a microwave to first heat your frozen rings on the defrost setting, and then reheat them until crispy using your preferred method of reheating.
