Can You Reheat Onion Rings? 

So yes, you can reheat onion rings.  

Can You Reheat Onion Rings?

The truth is you can reheat virtually any dish that has been refrigerated or frozen. It’s simply a matter of choosing the right appliance for the particular food you wish to reheat.  

In general, foods that have been breaded or fried are better when reheated in the oven or in an air fryer. Foods that have been grilled or baked are often best reheated when returned to the grill or the oven.  

When it comes to onion rings, I cannot help but think the best approach will be the air fryer.  

Quick, easy, and crispy.  

But let’s take a look at all of our options to be sure.  

Should You Reheat Onion Rings? 

Before we get into how to reheat onion rings, it’s important to consider whether you should.  

In terms of food safety and foodborne illnesses, you don’t really have anything to worry about when it comes to leftover breaded and fried onions.  

But it’s better to be safe than sorry, and you should always do your own research.  

I am including this piece from the BBC on what you need to know about reheating takeaways to help you in your investigation.    

How to Reheat Onion Rings in the Oven 

The oven may not be the fastest way to get your leftovers back on your plate, but reheating onion rings in the oven is likely one of the best ways to get them crispy because the last thing you want is soggy onion rings.  

  1. To get that heated, crispy effect, preheat your oven to 200 degrees Fahrenheit. That’s right. 200. We want to go low and slow.  
  2. Lay out your onion rings on a greased baking sheet, evenly spaced apart so they’re not touching.  
  3. Heat in the oven for about 10 minutes, checking to see if they’re heated through.  
  4. You can put them back in the oven for another 3-5 minutes if necessary.  
  5. Enjoy! 

How to Reheat Onion Rings in the Microwave 

Onion rings in the microwave are, in general, a bad idea.  

These appetizers are already prone to being soggy as leftovers, and the microwave will only add insult to injury.  But, if all you have to work with is the microwave, we’ll do our best! 

  1. Place your onion rings on a microwave-safe plate and cover them with a microwave-safe lid.  
  2. Heat in the microwave for 20 seconds at a time, checking each interval to be sure they are headed through. Do not overcook! 
  3. Serve and enjoy! 

How to Reheat Onion Rings in an Air Fryer 

Reheating onion rings in an air fryer is a cinch and will make you so glad you own this magical appliance.  

  1. Spray your air fryer basket with cooking spray.  
  2. Preheat the air fryer to 350 degrees Fahrenheit.  
  3. Place your onion rings in the air fryer basket, evenly spaced apart in a single layer.  
  4. Cook for 5 minutes and check that they are heated through.  
  5. If you need to, you can return them to the air fryer and cook for another minute or two.  
  6. Serve and enjoy! 

How to Reheat Onion Rings on a Grill 

You have a couple of options if you happen to be outside at your grill and want to reheat your leftover onion rings. The first method is as follows: 

  1. Wrap the onion rings in aluminum foil, like a basket, then cover them with more aluminum foil.  
  2. Place the wrapped onion rings over indirect heat on your grill and close the lid.  
  3. Allow them to heat for 10-15 minutes before checking to see if they are heated through.  

Your second option doesn’t require anything but the grill and some tongs for flipping: 

  1. Place the onion rings directly on the grill, but not over direct flame. 
  2. Flip them once or twice as they heat. This approach should only take a few minutes and will get you hot, crispy onion rings to enjoy with whatever else you are grilling.  

How to Reheat Onion Rings in a Toaster Oven 

If you’re working with a toaster oven, you are basically going to treat it like an oven.  

  1. Preheat the toaster oven to 200 degrees Fahrenheit.  
  2. Place your onion rings on a greased baking sheet, evenly spaced apart, and put the baking sheet in the oven for 15 minutes.  
  3. Check to see that the onion rings are heated through.  
  4. Serve and enjoy! 

How to Reheat Onion Rings in a Pan on the Stove 

Finally, you can always reheat your onion rings the same way they were cooked in the first place, in a frying pan! 

How To Reheat Onion Rings in a Pan on the Stove

  1. Heat cooking oil in a frying pan over medium heat. Olive oil is a favorite of mine because it is healthy and does not burn too hot or too quickly.  
  2. Place your onion rings, spaced out, in the hot oil and cook for a couple of minutes on each side. You are looking for them to crisp back up, which does not take long.  
  3. Serve and enjoy! 

WINNER – The Best Way to Reheat Onion Rings Is Using the Air Fryer

Thus, the best way to reheat onion rings is definitely in an air fryer.  

Hot, crispy, delicious, and quick. ‘Nuff said.
