Soggy precooked french fries will take about 4 to 5 minutes to bounce back to life in the air fryer. Depending on how thick your fries are you may need to add more or less time. Keep an eye on them so they do not overcook.

👩🏻‍🍳 Chef’s Tips & Variations

  • Always preheat your air fryer before reheating leftover fries.The fries will start to recrisp as soon as they make contact with the basket and the centers of each fry will stay soft and warm through.
  • For the best crisp, avoid overcrowding your basket. Depending on the size of your air fryer and the amount of fries you have, you may need to work in batches.
  • Each air fryer cooks a little different, so be sure to keep an eye on the fries and check on them every 2 minutes.
  • Halway through cooking sprinkle fries with seasonings like seasoned salt, Cajun seasoning or garlic salt.
  • Do you like your fries EXTRA crispy? Add a couple of minutes of cook time at the end. You can also spray them with cooking oil before reheating for extra crisp.
