McDonald’s fries, with their iconic golden color and crispy texture, are a beloved fast-food staple. But what happens to these delicious fries when they’re left over? Can you eat them the next day? The answer is yes, but there are some things you need to know to ensure they retain their crispy goodness. This guide explores the best ways to reheat McDonald’s fries, providing tips and tricks for achieving the perfect texture and flavor, even after a day in the fridge.

Reheating McDonald’s Fries: The Ultimate Guide


  • Spread the fries in a single layer on a microwave-safe plate.
  • Cover them with a slightly damp paper towel.
  • Microwave on high power in 20-second intervals, checking and stirring in between, until the fries are warmed to your liking.
  • This method is quick and convenient, but it may not yield the crispiest results.


  • Preheat the oven to 350°F (175°C).
  • Spread the fries in a single layer on a baking sheet.
  • Bake for 3-5 minutes, or until the fries are heated through and crispy.
  • This method is a bit slower than the microwave, but it produces crispier fries.

Air Fryer:

  • Preheat the air fryer to 350°F (175°C).
  • Place the fries in the air fryer basket in a single layer.
  • Air fry for 3-5 minutes, shaking the basket halfway through, until the fries are heated through and crispy.
  • This method is the fastest and most effective way to achieve crispy, restaurant-quality fries.

Tips for Optimal Results:

  • Avoid overcrowding: Reheating fries in a single layer ensures even heating and prevents them from becoming soggy.
  • Use a damp paper towel: The moisture helps to prevent the fries from drying out in the microwave or oven.
  • Don’t overcook: Overheating can make the fries dry and tough.
  • Seasoning: A sprinkle of salt or your favorite seasoning can enhance the flavor of the reheated fries.

Additional Considerations

  • Storage: Leftover McDonald’s fries are best stored in an airtight container in the refrigerator for up to 24 hours.
  • Texture: While reheated fries may not be as crispy as fresh ones, following the tips above can help you achieve the best possible texture.
  • Flavor: The flavor of McDonald’s fries may change slightly after being reheated, but they will still be enjoyable.
