Since you don’t want to eat them all yet, you save the rest for the next day. But wouldn’t it become soggy? Well, reheating is an option to still have that crispy and juicy experience on your palate. 

But how to reheat onion rings? How do you reheat it properly to have the full crispy experience? Well, worry not. Simply follow the steps I am going to show you, and you’ll have a crispy onion ring in no time!

Reheating Your Onion RIngs

Reheating your onion rings is a must to bring back their crispy texture. As long as you know how to reheat it, you serve your onion rings again for the next day. However, if not reheated properly, it would become soggy, squashy, and will taste bad. 

You need to find a proper balance to avoid that conclusion. The key to perfectly bring the crispiness back is medium heat and a frying pan, air fryer, or oven. Likewise, avoid using too much oil so that it won’t get greasy.

You need to take out the onion rings from the fridge 10-15 minutes before heating them. Otherwise, it would be hot on the outside but cold on the inside. With that said, here are the different ways to reheat your onion rings.

1.) How to Reheat using the Frying Pan

Using your frying pan is the simplest and the quickest way to have crispy onion rings, and here is how. For the frying pan, it is preferable to use a non-stick pan or a pre-seasoned frying pan. 

Firstly, add your room temperature onion rings to the frying pan. It’s fine if it isn’t heated beforehand because when the pan heats, so do will the onion ring. Make sure that the flame is at medium heat and the pan uncovered. Heat the onion rings for 3 minutes or more on each side. Keep in mind that the onion rings are already cooked once, so don’t cook it too long, or it will get burned.

Alternatively, you can add some oil to the pan to have a crispier texture, albeit a bit greasy. If you want to use oil, make sure to heat the oil first before putting in the onion rings. The more onion rings you have, the more oi you will need.

To keep the grease out, you can sit the onion rings first on a paper towel for a couple of minutes.

2.) Can I Reheat Onion Rings In Microwave?

Reheating onion rings on is unadvisable. Although the onion rings do warm a little, it still doesn’t have its iconic crispy texture. What you have instead is a warm but soggy and crumbly onion ring. 

Keep in mind that generally, fried foods do poorly on the microwave when reheating. Only use a microwave when you really have no options available for you. Microwaves do bring heat, yes, but none of their crispy texture is present. 

There are more do’s and donts to using a microwave, one of them is using steel on a microwave. So what happens if you happen to leave steel? For example, a spoon? To know more, check out What Happens If You Leave A Spoon In Microwave?

3.) Reheating On Oven or Toaster Oven

I would recommend reheating your onion rings the most on ovens or toaster ovens. Ovens or toaster ovens do a better job at heating the onion rings since the heat is distributed more evenly. Plus, ovens rarely collect moisture, making sogginess unlikely.

First, preheat your oven or toaster oven to 350 degrees Fahrenheit, or medium heat if your oven is not that accurate. Next, prepare your onion rings by placing them in an oven-safe dish and cover them in aluminum foil. 

Then, after preheating the oven, place the onion rings inside the oven for 10-15 minutes. Make sure to check them occasionally in case they are burning, Finally, after heating, eat them quickly before it turns cold. Otherwise, if they reach temperature, they would crumble. 

Using high heat is not recommended. If you use high heat, the outside is hot, but the inside is cold. So, allow it to take time to heat up on medium heat.

Reheating using an oven can come in different steps depending on which food is reheated. To learn more about reheating food, check out our article, How To Reheat Food in Oven The Right Way?

4.) How to Reheat Onion Rings In Air Fryer

Air fryers are great alternatives to using oven or toaster ovens. Air fryers act similarly to ovens, albeit in a much more concentrated way, which means quicker cooking! So in essence, the steps you will see are similar to the ovens. If you want to learn more about air fryers, check out this article, What Size of Air Fryer Is Right For You?

First, preheat your air fryer to 350 degrees Fahrenheit. Next, after preheating, put the onion rings on the basket and pop them into the air fryer for 5 minutes. After 5 minutes, flip it to have a more even cooking. After heating, serve immediately. 

If not eaten quickly and allowed to settle at room temperature, it will crumble. 


Onion rings are a delight to our palates, they are crispy and they make a great snack! Perhaps, you have too many onion rings and would like to save them for the next day. It would be a waste to not reheat them, no? So make sure to bring back their crispy texture! After all, nobody wants cold and soggy onion rings. 

Onion rings only last for 3 days, so make sure to reheat it before it expires. Do not reheat every batch of onion rings if possible. Only take what you need and reheat it. Reheating onion rings several times will only damage them.
