The Best Ways To Reheat Onion Rings 

While fried food is really easy to reheat, it can also go very wrong if you don’t do it the right way. In fact, reheating onion rings with the wrong method could make them soggy and very unpleasant.

If you have leftover onion rings from a previous meal, and you plan to reheat them the next day, you can let them rest in the fridge for the night in an airtight container.

Keep in mind that you can only reheat onion rings once, so if you don’t plan on eating all of them at once, only take out of the fridge the amount you need and leave the rest in the container.

You can keep fried onion rings in the fridge for up to 3 days, but we would recommend you don’t go beyond the first 24 hours. Freezing fried food is not a good idea either, so make sure to consume all of your onion rings within the time limit.

If you really need to freeze them, put them into a freezer-safe bag and make sure they do not overlap each other. Of course, before reheating frozen onion rings you need to defrost them. You can use the fridge or the defrost option of your microwave for that.

You can reheat shredded onion rings on your stovetop, or you can use your oven/toaster or air fryer. Each method requires a different process, so we’re going to go through each one in detail.

How to reheat onion rings in a toaster oven 

If you deem your traditional oven too big for the job or if you just want to save something on your energy bills, the toaster oven is a good alternative to reheat breaded onion rings.

  4. Place the baking tray on the top rack, so that the onion rings are elevated, since during reheating they’re gonna produce oil that could make them soggy at the bottom.
  5. Keep the temperature at 350 degrees and set the cooking time to 6-7 minutes.
  6. Check on the onion rings every couple of minutes and flip them regularly so that they can be evenly reheated.
  7. The results of using a toaster oven are very similar to those of the oven, so you can take your onion rings out once they’re golden brown and crispy, and serve them right away.

How to reheat onion rings in a skillet 

You may think that letting your oven or air fryer do all the work is the easiest way to reheat leftover onion rings, but using a skillet is actually the quickest and simplest way to achieve good results.

It doesn’t take much cooking knowledge to reheat onion rings on the stove, so don’t worry, you can achieve great results even if you’re a first-time cook. All you need is a pan and a bit of frying oil because with this method you’re actually frying the onion rings again.

Here are the steps to reheat onion rings in a skillet:

  1. Place a pan of suitable size on the stove on medium heat.
  2. When the pan is warmed up, add the frying oil. Don’t exaggerate but be generous, because if the onion rings don’t have enough oil, they will burn. Ideally, the level of the frying oil should be high enough to soak ⅓ of the onion ring (placed flat).
  3. Once the oil is heated, add the onion rings. If the oil is at the right temperature, it should start frizzling as soon as you put them in.
  4. Move them around frequently and flip them regularly, so that the entire body of each ring has been fully dipped in the oil.
  5. When the onion rings are golden and crispy, they’re ready to eat. It should take just a few minutes (less than 5 if the oil is well heated).
  6. Place a few pieces of paper towel on a soup plate and place the onion rings on the paper, so the extra oil is well-absorbed before you serve them.

While this isn’t exactly reheating as much as it’s cooking them all over again, it’s probably one of the best ways to get onion rings that are crispy and full of flavor.
