French Fry Problem: The cooked french fries on my plate look like they were reheated too long. They taste fine though so I just eat them anyway. What am I doing wrong here?

Answer – If it looks like they’ve been cooked too long then there’s probably something wrong with their cooking method. Try frying them again using fresh oil and cook until golden brown before serving. Alternatively, if you’re feeling adventurous try adding some salt after heating them – that’ll make sure they stay crispy longer.

In this area, we will be using four different appliances: oven, air fryer, broiler, and skillet. Choose which works for you and see which method has the best results in reheating French fries. 

Reheating French fries Oven

How to reheat french fries in an oven? Here we will show you how to do this step by step!

To reheat your fries through a hot oven or toaster oven, you will need to spend at least 25 minutes, maybe slightly longer for thicker fries or steak fries. Start by following these steps:

Spread the French fries on the baking sheet. You can place aluminum foil on top. 

Reheat until it gets toasty and crispy. Check every five minutes to get the exact result you want.

Parchment paper, baking sheets are great ways to place them on an oven tray or even a cookie sheet. Aluminum foil may also be used. If your fries are really dry you could use a little oil – and only tiny. (I like olive oil). Cooking spray is another good solution

The best way to get french fries back to their original state is by using medium high heat.

Reheating French fries Air fryer

Using an air fryer to make reheated fries is a modern way to do it. This and the oven are the best ways to make crispy fries from McDonald’s french fries. This is also the best method if you want to get a closer result in refrying. I find it best to preheat the air fryer and it will only take 6-10 minutes to do this.  The time for heating fries will vary – for loaded fries and steak fries it will take longer than old fries that are thin. See how to reheat nachos in an air fryer.

Cold french fries will also take slightly longer than fries which are already at room temperature and just need reheating.

  • Spread a single layer of leftover fries in the basket and put a tablespoon of vegetable oil. 
  • Air fry for a maximum of eight minutes until you achieve your desired texture. 
  • Make sure that the air fryer basket is not congested to allow the heat to circulate at every angle of the fries.

Reheating French fries – Broil

Using a broiler for reheating French fries will only take at least 10 minutes of your time. This may not be very common to everyone but it still works anyway. The broiler will give a crispy result but it needs more of your attention since it tends to burn the fries, especially the thinner ones. A longer time of broiling the fries will also lead to being overcooked on the inside yet crispy on the surface. To do this, follow the steps below. 

Place aluminum as the base and arrange a layer of fries for proper heat distribution. 

Preheat the broiler for 5 minutes over low to medium heat.

Broil the fries for 5 minutes or until you get the desired texture. 

Flip to the other side and wait until it gets golden brown and warmed. 

Let it cool and serve.

Reheating French fries through a skillet

Reheating French fries through a skillet is also one of the most common ways to do it, especially if you do not have any oven, air fryer, or broiler. And of course, you will need a stovetop for this method. Follow these steps to efficiently do it:

Prepare a medium-sized pan or deep fryer if you have at least one bowl of day-old fries to reheat. 

Spread 1 tablespoon of oil (vegetable, canola, or olive oil) over medium-high heat. Make sure it gets very hot before reheating the fries. 

Place an even, single layer of fries. Make sure it has enough space for proper even crispiness. 

Cook and stir for 3 to 5 minutes or until you get your desired result. Do not forget to flip on both sides for even crispness. 

Once they are done, place them on a double-layered paper towel to excrete the excess oil 

Spread salt or cheese on top.
