Fortunately, this just isn’t true! There are many options for reheating french fries that can be almost as good as the originals, if not just as good.  

Don’t believe me? This article will help you figure out how to reheat french fries that can still taste amazing, and which ways might not be so great.  

Can You Reheat French Fries?  

Of course! Almost any food can be reheated. The question is whether that reheated food will be good or even edible. It also often comes down to which method you use.  


Reheating french fries is possible

For example, foods that have been breaded or deep fried are often best reheated in an oven or an air fryer while foods that have been grilled or baked are usually better when reheated in the oven or on the grill.  

Our experience tells us that french fries are probably best reheated either in the oven or in an air fryer, but let’s see what the data shows.  

Should You Reheat French Fries?  

First, let’s be sure we actually should reheat french fries. Some foods should be left alone, like fish that has been in the fridge for more than a few days or cheeses that have sat open and exposed to the air.  

But when it comes to french fries, we’re talking about a cooked potato; you should be find for a couple days in the fridge 

Of course, you should always do your own research and investigate according to your own specific situation. The US Food and Drug Administration is a great place to review the guidelines about safely reheating food.  

How to Reheat French Fries in the Oven 

When reheating french fries in the oven, preheat your oven to 425 degrees Fahrenheit and place your french fries on a baking sheet, spread out so they’re not touching. If you have parchment paper, put that down under your fries, as it will keep the fries from sticking to the baking sheet.  

Cook your fries for 8 to 10 minutes and give them a quick toss halfway through. If you want them a bit crispier, give them another 2 or 3 minutes.  

How to Reheat French Fries in the Microwave 

Everyone who’s anyone will tell you never, ever, ever to reheat your french fries in the microwave. It is this practice that has given reheating french fries a bad name,  

But, if a microwave is all you’ve got, or you insist on this method, you can try this:  

Lightly dampen 3 pieces of paper towel and place them on a plate; then place your fries on top of the moist paper towel. Heat your fries in the microwave on full power for 20 seconds.  

Check your fries. If they seem good to you, eat and enjoy. If not, try another 20 seconds, and then another, until they have reached the crispness you desire.  

How to Reheat French Fries in the Air Fryer 

Thank goodness for air fryers! They have helped us heat and reheat all kinds of foods.  

For reheating french fries in an air fryer, simply preheat your air fryer to 350 degrees, place your fries in a single layer in your fryer basket, and cook for 3 to 5 minutes. I recommend shaking the basket halfway through to make sure they reheat evenly. 

If you want them a bit crispier, you can heat for a minute or two more.  

Be sure you keep your fries spread out for maximum crispness. 

PRO TIP: If you love french fries, I’m telling you that it is worth investing in an air fryer. If my air fryer didn’t do anything else, I’d own it just so I could reheat french fries.  

How to Reheat French Fries on the Grill 

Let’s say you’re already cooking on your grill, and you want to add your fries. If you’re thinking of reheating french fries on the grill, you’re in luck. You totally can.  

Place your fries in a disposable aluminum tray, in a single layer, spread out, and then place your tray on an already heated up grill. Close the top and cook for 15-20 minutes.  

Your fries should come out heated through and having retained their crispness to enjoy along with the rest of your meal.  

Don’t believe me? I didn’t either until I tried it and I was pleasantly surprised. Pro tip – you can also reheat french fries on a smoker if you are smoking meat. The smoke from the wood will give the fries a unique flavor. 

How to Reheat French Fries in a Toaster Oven 

The toaster oven has saved many a college student and bachelor from having to venture out for a new take out meal or invest in a full size oven when it is not always possible. 

How To Reheat French Fries in the Toaster Oven 

The great news is that a toaster oven can also be a great way to reheat fries.  

Heat your toaster oven to 400 degrees, place your fries on a sprayed baking sheet, spread out, in a single layer, and cook for about 7 minutes. Toss your fries and check for enjoyment level.  

You can always pop them back in for another couple of minutes for extra crispness.  

WINNER – The Best Way to Reheat French Fries Is Using the Air Fryer. 

In the end, the best way to reheat your fries has got to be the air fryer. It will remove any excess sogginess or oil, get your fries back to you in a short amount of time, and heat them all the way through.  

The air fryer definitely seems to be the winner in most cases. But, worry not. If you don’t have an air fryer, you can always use the oven, which comes in a very close second.  

With an oven, you only lose a little bit of time, and if you have no air fryer on hand, who’s really going to complain? You’ll still get great, reheated, crispy fries.
