best ways to reheat french fries

 Everybody loves the sizzling hot, crispy, salty, and fresh fries due to their compatibility with just about any meal. 

According to South Florida Reporter, the average American eats approximately 30 pounds of fries every year. 

However, it’s always a love-hate relationship as consumers have to either finish or throw them away.

Well, that wouldn’t be a problem if there was an easier way to reheat french fries and still keep them hot and crispy.

Did you know? –– Reheated french fries are healthier than fresh french fries? Reheating increases fiber content and reduces starch content.

This post will discuss several ways to give your fries a mouth-watering revival so you don’t have to worry about food wastage.

Before we dive into the main ideas, here are a few quick tips when storing your french fries.

  • Consume your fries within three days; they get stale pretty quickly.
  • When refrigerating, store leftover fries in an airtight container to keep the potatoes from absorbing other flavors.
  • Skinny thin, fast food fries may not be the best to reheat as they are cut for deep fryer efficiency.
  • When making fries from scratch, choose a potato that can sustain second heating, such as Kennebec and russet potatoes.

Differences Between Freshly Made French Fries and Reheated French Fries

If you often buy your french fries, how do you know they are fresh and not reheated? 

This table will help you understand the difference between freshly made fries and reheated fries.

Deep Fry them a Second Time

Refrying is one of the best methods of reheating french fries. The Belgian style, which is a double frying process, restores the fry’s soft center and delightful crispy exterior. 

If your fries are relatively soft, the Belgian style may not be a good option as the hot oil may cause them to fall apart. This method works best for thick unseasoned fries.


  1. Heat canola or sunflower oil over medium-high heat. (375 degrees)
  2. Carefully add your leftover french fries to the hot oil and fry for three to five minutes.
  3. Remove and place your fries on a paper towel and allow them to cool.
  4. Add salt and serve.

Skip the Microwave

Any food expert will tell you that reheating fries using a microwave is always a bad idea, as it makes them soggy.

The use of a microwave to reheat fries has strongly reinforced the myth “fries are not good if left for more than two hours.” A microwave should never be used to reheat crispy foods.

Microwaves work by heating the water molecules present in your food using electromagnetic radiation. 

Reheating fries using the microwave, which has water in them, inevitably makes them soggy. Additionally, seasoning and the type of oil used can impact the taste of your fries when you use the microwave.

Reheat French Fries on the Stove

Use a Hot Oven

If you’re not an oil person, you probably already learned this trick—using the oven to reheat french fries. 

Any oven gives the desired results as long as it is preheated to the correct temperature (400-450 degrees). 

An oven restores the golden crisp in your fries and can be the best option to use if you need your fries crispier with a touch of the grill in flavor. 

Here are steps to follow for perfectly revitalized fries:

  1. Preheat your oven and keep the temperature from 425 to 450 degrees.
  2. Prepare your baking sheet with oil, cooking spray, or aluminum foil.
  3. Place your baking sheet inside the oven as it heats up.
  4. Once the sheet is hot, place your fries carefully in a single layer while spreading them and allowing lots of space between them.
  5. Close the oven door and reheat your french fries for 5 to 10 minutes. Please give them a shake about halfway through the process to allow even cooking.
  6. Remove from the oven, drain on a paper towel and allow them to cool.
  7. Add salt or any other seasoning and serve.

Reheat French Fries on the Stove

 If you don’t want to use oil or turn your oven on a sweltering summer afternoon to reheat fries, pan-frying can be a more effortless and economical way to get you some surprisingly good results. 

You don’t have to use any oil for this method as there is enough oil residue on the fries. However, you need to be quite careful with the heat, or you might end up burning the fries. 

Fry them in batches to prevent overcrowding and promote efficiency and even cooking.

Here’s what to do:

  1. Get a large, heavy pan and place it on medium-high heat. You can swirl a few tablespoons of canola oil if you need more oil.
  2. Add your fries and keep flipping them around every 2 minutes until they’re hot and crisp enough.
  3. Turn off the heat, and place the fries on a paper towel to get rid of grease and cool.
  4. Salt and serve.

Pro tip: Canola oil is the perfect reheat master for your leftover fries. It contributes a neutral flavor and high smoke point.

Use an Air Fryer

Use an Air Fryer

The air fryer allows you to reheat without using a lot of oil, which makes it the perfect option to reheat french fries. 

Unlike the microwave, which works by heating water molecules, the air fryer circulates heat around your food using one or multiple fans to ensure the fries are heated from all angles. 

There is no preheating required, but if you want to keep the temperature low (350 degrees maximum).


  1. If you are using oil, add it together with the fries.
  2. Toss your fries and spread them in a single layer in the fryer basket.
  3. Set the heat at 375 degrees and cook for about 4 to 6 minutes or until the fries achieve your desired results.
