Here are our ultimate tips for heating up leftover fries and making them as crispy as day one!

How To Reheat French Fries In An Air Fryer

Due to the capacity of the basket, this method is suitable for reheating a small quantity. Here is how to make leftover fries crispy:

  • 1. Place them in the basket in a single layer.
  • 2. Turn on the air fryer to 350 ºF.
  • 3. Cook for 3 to 5 minutes until they are warm and crispy. The estimated cooking time depends on the thickness of the fries and how crispy you want them to be.
  • 4. Sprinkle some salt (if necessary) and serve!

How To Heat Up Fries In A Skillet

This method is also suitable for reheating a small quantity of leftovers. If you have tons of them, work in batches and avoid overcrowding the pan.

  • 1. In a large nonstick skillet, pour vegetable oil to cover the pan’s entire surface. The oil should be enough to essentially re-fry the fries.
  • 2. Heat the skillet on medium-high heat until the oil is simmering hot.
  • 3. Put the fries in a single layer and sprinkle them with salt.
  • 4. Cook them for a few minutes until they are warm and crisp. Add your favorite toppings, such as dried herbs, black peppers, or grated cheese (optional).
  • 5. Mix well and remove them from the skillet.
  • 6. Drain the excess oil on a plate lined with a paper towel.

How To Reheat Fries In An Oven

For reheating a massive amount of leftovers, this technique is your best option.

  • 1. Preheat your oven to 400 to 425 ºF.
  • 2. Crumple up an aluminum foil and spread it over a baking tray.
  • 3. Spread the fries across the baking tray in a single layer.
  • 4. Spray them with cooking oil.
  • 5. Bake for 5 to 10 minutes until they are golden brown and crispy.
  • 6. Remove them from the oven.
  • 7. Sprinkle some additional salt (if necessary) and serve with your favorite condiments!



The first thing to remember about reheating fries is the microwave comes the least. Instead, reheat them in an oven, skillet, or air fryer. This way, you’ll make them crispy again.

Follow our tips to reheat leftover fries the right way, so they will be as pleasant and crispy again as they just come out from the deep fryer!
