How To Reheat Fries in Air Fryer?

Do you find yourself with leftover fries, and not sure how to enjoy them as crispy as they were when served fresh? 

Worry not, because we’ve got the solution: reheating fries in an air fryer! This method brings your cold, soggy fries back to life and restores their crunchy deliciousness.

Using an air fryer to reheat fries is a game-changer. It saves you a lot of time. It also ensures that you achieve a crisp golden exterior, without the hassle of frying or reheating them in the oven. 

In short, you have to preheat your air fryer, arrange your fries in a single layer, and cook for a few minutes. I will tell you about the whole procedure step by step along with a visual demonstration.

Why Should You Reheat Fries in the Air Fryer?

Reheating fries in an air fryer is the best option for several reasons, all of which make a significant difference in bringing life back to your leftover fries. 

Let’s look at these reasons:


The air fryer uses circulating heat to reactivate the oil in the fries, resulting in a crispy exterior without drying them out on the inside.

Even Heating

Preheat your air fryer for a couple of minutes. Doing so allows the fries to cook more evenly. 

No extra Oil Needed

There’s no need to add additional oil since the air fryer uses the existing oil on the fries to crisp them back up again.

This, for me, is the best reason to reheat fries in an air fryer.

Quick and Easy

Air fryers take only a few minutes to reheat your fries, making it a convenient and fast option.

Healthier Choice

Reheating the fries in an air fryer is a healthier alternative to deep-frying, helping you avoid unnecessary calories and fat.

It also helps to whip up a healthy meal within minutes.

Now let me be clear, I am not saying fries are healthy (especially if they are originally made through deep frying). However, reheating in the air fryer is a healthy way as it doesn’t need any additional oil.

How to Reheat Fries in Air Fryer 

Let me show you step-by-step how to reheat fries in the air fryer. I had some cold, leftover KFC fries that I wanted to reheat.

Fries to reheat in air fryer

Step One – Preheating 

Regardless of the brand or model, the key is to preheat your air fryer to achieve evenly cooked and crispy fries. 

Set the temperature to 350°F (180°C) for five minutes. Preheating simulates a hot oil temperature and helps the fries to reach the optimal temperature for reheating.

Step Two – Place the Fries in the Air fryer Basket

Before placing the fries into the air fryer, you need to arrange them properly. 

Spread out the fries in the air fryer basket, keeping them in a single layer. 

Place the Fries in the Air fryer Basket

Avoid overcrowding or stacking them. This will allow the hot air to circulate more evenly and promotes crispiness. If you have a lot of fries, reheat them in batches.

Step Three – Reheating

Set the time and temperature for five minutes at 350°F (180°C). Keep an eye on the fries after the initial three minutes.

If needed, you can add an extra minute or so for thicker fries. 

Here is the final result.

I noticed with delight how the soggy and lifeless fries came back to life.

Let me share a before and after comparison pic so you can see it for yourself.

Additional Instructions

Allow me to share a few cooking instructions so your fries come out delicious and crispy just like mine.

  • When arranging the fries in the air fryer basket, make sure to create a single layer without overlapping. This allows each fry to cook evenly and stay crispy. 
  • For thicker fries, you might need an extra minute or two of cooking time.
  • If you don’t want the fries to be crisp and just hot, follow the preheating and cook for only three minutes after placing the fries.

By following these simple steps, you’ll enjoy perfectly reheated fries every time. Serve them hot with your favorite dipping sauce.

Tips for Crispy and Delicious Fries

Reheating fries in an air fryer can lead to a tasty and crunchy snack with the right approach.

Let us look at some of the helpful tips below:

Don’t Overcrowd the Basket

When placing your fries in the air fryer, do not overcrowd the basket. Spread the fries out evenly, and avoid filling the basket more than halfway. 

This helps in even heat distribution and proper circulation of hot air. It also prevents the fries from becoming soggy or unevenly cooked. 

If you ignore this tip and overcrowd the basket, your reheated fries will not be as crispy and delicious as they could be.

Shake or Toss Them

During the reheating process, it’s important to periodically shake or toss the fries. This will help in even cooking and improve the overall crispiness of your snack.

If you forget to give them a shake or toss, some fries may be less crispy than others, leading to an inconsistent texture.


Add a touch of your favorite seasonings after reheating to enhance the flavor.

You can use garlic powder, seasoned salt, or any other spices you prefer.

No Oiling 

The fries are already cooked in oil, so you don’t need to add extra oil. Doing so will make your fries greasy and soggy.


Preheat your air fryer to 350 degrees Fahrenheit for about five minutes.

This will help the fries cook more evenly.

Keep an Eye

Monitor the fries closely, as different thicknesses and types require varying cook times.

Thicker fries like steak fries or waffle fries might need extra time compared to thinner varieties.

Extra Crisping

If you like your fries super crispy, cook them for an extra minute or two. Keep an eye on them to avoid burning.

Avoid Burning Them

Stay attentive and check on the fries periodically, removing them as soon as they achieve the desired level of crispiness.

Remember these tips when reheating fries in your air fryer, and you’ll have delicious, crispy fries in no time!

Thicker than regular fries, steak fries might need a bit more attention when reheating in the air fryer.

Alternative Reheating Methods

Aside from using an air fryer, I am sharing two other methods you can use to reheat fries: Oven and Stovetop.

Oven Reheating

An oven is a classic option for reheating fries. Here is how to do it:

  • Preheat the oven to 350°F (180°C).
  • Spread your fries on a baking sheet lined with parchment paper. Spread them out in a single layer.
  • Bake for about 10-15 minutes.

Reheating fries in an oven has a few pros and cons. One advantage is that it’s great for larger quantities of fries.

On the downside, using an oven takes more time to reheat compared to an air fryer.

Stovetop Reheating

You can also reheat your fries using a stovetop. Follow the steps below:

  • Heat a pan over medium heat.
  • Add oil
  • Place your fries in a single layer in the pan, and avoid overcrowding them.
  • Cook for three to five minutes, turning occasionally.

The stovetop method has its pros and cons. One plus is that it’s faster than using an oven and doesn’t require any preheating. 

However, a disadvantage is that avoiding soggy or unevenly heated fries can be more challenging. It also works best for smaller quantities of fries.

How to Use Reheated Fries in a Meal

Wondering how to incorporate reheated fries into your meals? You’ve come to the right section!

Here, we’ll give you some creative ideas to transform those fries into delicious dishes.

First, consider turning your fries into fully loaded-nacho fries. This recipe requires spreading your reheated fries onto a plate and topping them with your favorite nacho ingredients.

Next, add shredded cheese, black beans, jalapenos, diced tomatoes, and sour cream. Pop this in the oven for a few minutes just to melt the cheese, and voilà! Nacho fries are ready to go.

Another great idea is to add reheated fries to a breakfast hash. Simply sauté diced onions and bell pepper in a skillet, then toss in your reheated air-fried fries. 

Add some cooked diced bacon, sausage, or ham to the mix. Top it all off with a fried or poached egg, and you’ve got a satisfying breakfast dish.

Feeling more adventurous? Why not try adding your reheated fries to a poutine-inspired casserole? 

Layer your crispy fries in a deep dish and cover them with cheese curds and a rich, homemade gravy. Bake this in the oven until the curds are melted and slightly bubbly. Grab a fork and dig in!

Finally, if you’re in the mood for a light salad, you can use your reheated fries as croutons!

Cut the fries into smaller pieces and toss them into a mixed greens salad with your favorite veggies, some grilled chicken, and your preferred dressing.

This unique twist adds an extra crunch, making your salad more exciting and enjoyable.

Now that you have these ideas, feel free to get creative and find other ways to incorporate your reheated fries into delicious meals.

Just remember to have fun and enjoy the process of experimenting with new dishes!

What Not to Do While Reheating Fries in the Air Fryer

Reheating fries in an air fryer is a great way to bring them back to life, but there are a few things you should avoid to end up with perfect, crispy fries.

Here’s what you shouldn’t do:

  • Putting too many fries in the basket can make them soggy, as they won’t have enough space to crisp up properly. Spread the fries in a single layer, or not more than two layers.
  • The fries already have oil in them. It is more than sufficient to retain the crispiness. Using extra oil will make them greasy. 
  • To achieve a crispy texture, it’s important to reheat the fries at 350°F to 400°F. Heating them at a lower temperature will make them limp and soggy.
  • While it’s a good idea to shake the basket halfway through cooking to ensure even reheating, shaking it too much can break apart the fries or cause them to stick together.
  • Don’t ignore thickness variations. Thicker fries may need a bit more time to reheat than thinner ones. Pay attention to the thickness and adjust the cooking time accordingly.

By avoiding these missteps, you’ll be on your way to enjoying delicious, crispy fries that taste almost as good as when they were freshly made.

Drawbacks of Reheating Fries in the Air Fryer

Let us look at some of the drawbacks of reheating fries in the air fryer.

Smaller Capacity

In comparison to an oven, air fryers often have a smaller capacity, meaning you may need to reheat your fries in batches, which takes more time.

This may not be ideal if you have a large quantity to reheat.

Uneven Heating

As much as air fryers promise even cooking, overlapping your fries in the basket can still result in some pieces not heating up as well as others.

Make sure to arrange your fries in a single layer without overlaps to avoid this issue.

Initial Expense

Air fryers can be expensive, especially if you opt for a high-quality model.

If you don’t already own one, it might not be worth purchasing one solely for reheating fries.

Additional Appliance

Owning an air fryer means one more appliance on your countertop or in your kitchen cabinets, taking up valuable space.

If you have limited kitchen space, this could be a downside.

Keep in mind that the results with an air fryer are usually superior to other reheating methods.

So if you’re able to work around these disadvantages, opt for reheating in an air fryer.
