Pro Tips 

  • A little oil can help you achieve super crispy fries. Use spray oil for the air fryer or the oven and 1-2 teaspoons for the skillet method. 
  • The actual time to reheat fries will depend on the size and thickness of the fries. 
  • Watch them closely so you don’t burn the fries. 
  • For even cooking, be sure you don’t crowd or overlap the fries. 
  • If desired, finish with a fresh sprinkle of salt or your favorite seasoning.
  • Air fryer temperatures can vary depending on the make and model. I recommend starting with less cook time, checking food for doneness, then adding more time as needed.

Storage

  • Store – Leftover fries can be stored in the fridge for up to 4 days.  
  • Reheat – Only reheat what you can eat right away, as fries don’t reheat well more than once. 
  • Freeze – You can freeze leftover fries, but the texture will change and they will not be as crispy and tasty.
