Best Way To Reheat Fries

I always remember having the same takeout with my parents when I was in my teens. It was not that frequent as we would normally go out for a meal rather than order in.

But when we did order takeout it would be doner kebab and fries for me and my mum and southern fried chicken for my dad.

My mum always pointed out that by the time the takeaway arrived at our door it was cold and needed warming up in the microwave.

Before the delivery guy arrived, she would have warmed up dinner plates in the microwave.

Then when the food got here into the microwave went the French fries. They were always so soggy, even if they were piping hot. It put me right off reheating French fries.

But fast forward a couple of decades and here I am today showing you the best way to reheat French fries and best of all, it doesn’t involve microwave style soggy French fries.

Instead, we are talking the amazing magical powers of the air fryer.

Can You Reheat French Fries?

I often get asked can you reheat French fries, or more specifically can you reheat French fries in the air fryer.

Well, it’s a big fat YES. The air fryer is fantastic for reheating fries and out of the different ways you could reheat fries it is the best.

You can do this with any fries, regardless of how they were first cooked.

How To Bring French Fries Back To Life?

Shall I let you in on a culinary French fries secret? French fries taste best when they have been cooked twice.

At one temperature first and then at another. The reason why our air fryer cajun fries are so good and how places like Five Guys make their amazing fries.

That is why reheating French fries in the air fryer is such a genius move.

You see they are already cooked and have gone cold, but you are using the air fryer to give them their second cook and make them crispy again.

How To Make Fries Crispy Again?

You know it is all about the extra virgin olive oil. The olive oil helps add moisture back to the fries and also give your fries that amazing crisp.

But the good news is that you do not need a lot.

Simply spray the top of your fries with extra virgin olive oil and then air fry.

How Long To Reheat Fries In Air Fryer?

The air fryer cook time to reheat French fries is much faster than you would think. In fact, our French fries took JUST 10 minutes. You could do it in less if you just want to reheat fries and don’t want them crispy.

But I am all about crispy French fries in the air fryer.

What To Do With Leftover French Fries?

I watched this leftovers cookery show on Netflix. It was a bit boring, so I only made it to the second episode. But it was amusing watching them do lots of gourmet things with leftover French fries.

But what I love to do with leftover French fries is to turn them into cheesy fries. After adding the extra virgin olive oil add a layer of grated cheese and air fry for the last couple of minutes with the cheese on top.

Reheated cheesy fries are amazing.

You can also add a few other ingredients and turn them into loaded fries.

Reheat Sweet Potato Fries In Air Fryer

Do you have sweet potato fries that you want to reheat in the air fryer instead? Well, we have done those too and have found they require a little more olive oil but come out just as crispy as when you first started eating them.

So, if you are reheating sweet potato fries, then I recommend you add a little more extra virgin olive oil and then check to see if they are crispy enough when the air fryer beeps. If not, add a couple more minutes cook time to get the crisp spot on.

    Can You Reheat French Fries?



Cheese. If you would like cheesy fries, do the recipe above, add your favourite cheese and then air fry for a further 2 minutes at 200c/400f.
Salt. I recommend salting your fries. Because the fries have been in the fridge, they will lose their salt and its amazing how bland they are if reheated without salt.
Oil. I recommend spraying with extra virgin olive oil or your fries will not get as crispy as it reheats back through.
Frozen. If reheating frozen fries, I recommend you follow our air fryer frozen French fries recipe instead as it will be more accurate to your needs.

    Looking to do this for ages and never came across a recipe that was right but yours really was the best timings i could fine thanks the fries tasted so good.

    • Hello Paul,

      Thank you for your feedback. After careful consideration from our millions of readers we came to the conclusion after going through our survey that the majority 80% for longish posts compared to 10% for shorter posts and 10% did not have an opinion.

      So with this in mind we decided to do longer posts and for the minority we have a jump to recipe button located at the very top of the post so if you press it you will jump to the recipe and miss the (life story) and this then keeps everyone happy or so we thought. We did not take into account that jump to recipe is quite hard to understand for the minority of people.

    • Hi Loren,

      That temp seems very high just to have one temp. You could some frozen products and maybe some fries but i think that would be it, as you need a medium temp to cook food in the middle and not burn the outside, is there any recipe book with it ? 🙂
