To reheat French fries and retain their crispiness, use an oven preheated to 400°F or an air fryer set to 375°F. Avoid using a microwave as it tends to make them soggy.

Best Methods to Reheat French Fries

When it comes to reviving leftover French fries, the top methods include using an oven for optimal crispiness, an air fryer for a modern touch, or a stovetop skillet for a classic approach.

These methods ensure you can enjoy your fries with the same crispy delight as when they were fresh.


The oven is your best friend when it comes to reheating French fries. Here’s how:

  1. Preheat your oven to 400°F (205°C).
  2. Spread your fries in a single layer on a baking sheet.
  3. Bake for about 5 minutes or until they’re crispy.


The microwave can be a speedy solution, but it’s not the best choice for optimal crispiness. Fries tend to become soggy when reheated in the microwave but they can still be tasty.

  1. Spread: Lay a paper towel on a microwave-safe plate and spread your fries out.
  2. Heat: Microwave in 30-second intervals until warm. Be careful not to overheat as they can become soggy.

Air Fryer

Air fryers have gained popularity due to their ability to make foods crispy without much oil. This makes them great for reheating fries.

  1. Preheat: Warm up your air fryer to 375°F (190°C).
  2. Cook: Place the fries in the basket without overcrowding and cook for about 3-4 minutes.

If you’re without fancy appliances, a simple skillet can do the trick.

  1. Heat: Warm a non-stick skillet over medium heat.
  2. Fry: Add the fries, avoiding overcrowding, and cook until they’re golden and crisp.

Tips and Tricks

  • Season After: Once reheated, sprinkle with a little salt or your favorite seasoning to freshen up the taste.
