Onion rings are one invention that no one regrets. With their crispy exterior and mouth-watering interior, you’re not alone if you often get carried away and make too many in one batch.

However, if you’re worried about whether reheated onion rings could ever have the same texture, appearance, or taste as freshly made ones, you’re in luck!

As long as you know how to reheat onion rings using an appropriate method, you can restore their original glory and serve them again another day.

There are three most commonly used methods for reheating onion rings: the oven, the air fryer, and the microwave. Here’s what you need to know.

Warming up onion rings

The tricky part is figuring out how to reheat onion rings without them getting soggy because when they get squashy, they taste bad and start falling apart as well.

Still, you can employ the following three ways to get reheated onion rings.

Reheating onion rings in the oven

One of the best ways to reheat onion rings is in the oven or a toaster oven. Ovens ensure that your onion rings stay crispy and don’t collect too much moisture, resulting in sogginess.

Preheat your oven to 350 degrees Fahrenheit.
Place the onion rings in an oven-safe dish and cover the dish with aluminum foil.
Once the oven is preheated, you can place the dish of onion rings inside for around 10 to 15 minutes. Keep checking on them to ensure that they aren’t turning brown or getting burned at the edges.
Once heated, don’t let the onion rings go back to room temperature because heating them again may cause them to crumble. Eat them when they’re still reasonably warm.

Reheat onion rings in an air fryer

Another great way to reheat onions rings, and while keeping them as crispy as they originally were, is by heating them with an air fryer.Here’s how you do it:

First, add a coating of cooking spray to the onion rings to ensure that they are heating evenly and thoroughly.
Next, turn your air fryer up to 350 degrees Fahrenheit and place the onion rings in the basket for around 10 minutes. Like you would with the oven, you will have to flip the onion rings after five minutes, so all sides get an equal amount of heat.
Cold onion rings lose their color a little when they’re kept in the refrigerator. You’ll know that your onion rings are ready to take out of the air fryer when some of their original golden brown color returns. They should also feel crispy.

Reheating onion rings in a pan/skillet

You may have already wondered: Can you reheat onion rings in a pan and get them to stay crispy at the same time? The answer is yes, that is if you know how to do it properly. It’s the most commonly used way to reheat them.

It’s a similar process to when you fried them the first time if you made them yourself, but you don’t have to spend the same amount of time because they’re already cooked.

First, make sure the oil in the pan is heated before placing the onion rings inside. It’s preferable to use vegetable oil, as it works better with higher heat levels.
Next, place the onion rings in the pan for a couple of minutes.
You should also flip them over and allow them to heat up equally on both sides without burning them.
To remove the excess oil, you should place the rings on a paper towel after taking them out of the pan and let them sit for a couple of minutes until they’re warm enough to eat.
Remember, your onion rings have already been fried once, so you don’t have to wait for them to brown further. They’ll only end up getting burned.

Instead, please keep them in the pan only long enough to reach an adequate temperature before taking them out. At most, you’ll notice that the color looks fresher than when they were in the refrigerator.

Reheating onion rings in the microwave

It’s better not to reheat onion rings in the microwave, as it does take away from their crispy texture and can make them moist and crumbly. Fried food usually doesn’t fare well in the microwave when it comes to reheating it, so you should only use the microwave if none of the other options are available to you.Keep in mind that if you do reheat the onion rings in the microwave, they’ll be warm but will retain none of their original taste or appeal.

How to reheat frozen onion rings

When you have onion rings that have been in the freezer, you can use an oven to reheat them.

For this, you’ll have to preheat the oven to 400 degrees Fahrenheit and cover the onion rings in oil before placing them on a baking sheet.
It would also help if you seasoned them again for better results. Make sure they’re placed far enough apart for all of them to receive equal amounts of heat. You might also want to flip them over and rotate them for better heat distribution.
You can bake them in the oven for around eight to 10 minutes after covering them with a sheet of aluminum foil.

Tips from the pros

It’s important to remember that you should only reheat as many as you need and consume them before they go cold again when you reheat frozen onion rings.When onion rings have been reheated before, they will not have the same taste or be crispy again if you reheat them for a second time. You also won’t be able to store them back in the freezer after they’ve already thawed out once because they’ll start to fall apart.

The bottom line

By now, you must have a clear idea of which methods you can use when warming up onion rings. Remember to keep a careful eye on any signs of burning and eat them before they cool down again. As long as you follow the steps provided, it would be best if you ended up with crispy, great-tasting reheated onion rings that look as good as fresh ones.
