How to Reheat Fries in air Fryer

Welcome, fellow food enthusiasts! If you’re anything like me, you’ve faced the disappointment of soggy, reheated fries. But fear not! The air fryer, our modern kitchen miracle, has transformed the art of reheating fries, ensuring they come out crispy and delicious every time. This guide will walk you through the steps to achieve the perfect reheated fries in your air fryer.

Why Reheat Fries in an Air Fryer?

Reheating fries in an air fryer isn’t just a method; it’s a game changer. Unlike microwaves that make them soggy, ovens that can dry them out, and stovetops that require too much oil, air fryers use rapid air technology to circulate heat around the fries. This process revives the crispiness without the added grease, making it a healthier option for those crunchy cravings.

Preparing to Reheat Fries in Your Air Fryer



  • 1-2 tsp. oil
  • Pinch seasoning of your choice optional
  • cooked fries


  • Preheat the air fryer for 5 minutes. Meanwhile, place the fries in a bowl.
  • Drizzle 1 teaspoon oil or use an oil spray and seasoning of your choice, optionally.
  • Reheat the fries in an air fryer at 210 C| 410F, for 4 minutes.
  • Serve hot.

The Perfect Temperature and Timing

The key to perfectly reheated fries lies in finding the right balance of temperature and time. For most fries, reheating at 350°F for 3-5 minutes should suffice. However, adjust as follows for different types:

  • Thin-cut fries: 3-4 minutes.
  • Thick-cut fries: 5-6 minutes.
  • Sweet potato fries: 4-5 minutes.

Remember, these are starting points. Depending on your air fryer model and the amount of fries, you may need to adjust.

Tips for the Best Results

  1. Shake the Basket: Halfway through cooking, give the basket a good shake. This helps the fries reheat evenly.
  2. Don’t Overcrowd: Cooking in batches is better than sacrificing texture.
  3. Oil Spray: A light spray can bring back the ‘just cooked’ feel, but use it sparingly.

Common Mistakes to Avoid

  • Overheating: Fries can quickly go from crispy to burnt. Keep an eye on them!
  • Skipping the Preheat: This step ensures your fries reheat evenly.
  • Too Much Oil: A light spray is enough. Too much oil can make fries soggy.
