Preheat the Air Fryer: Start by preheating your air fryer to the recommended temperature for frozen French fries. This is typically around 380-400°F (193-204°C).

Prepare the Fries: While the air fryer is heating up, take the frozen French fries out of the freezer. There's no need to thaw them. You can use as many as you want, depending on your air fryer's capacity.

Add a Light Coat of Oil: To ensure the fries get crispy, lightly spray or toss them with a small amount of cooking spray or oil. This helps in achieving that golden-brown crunch.

Season (Optional): If you like your fries seasoned, sprinkle them with salt or your preferred seasonings. Toss them to distribute the seasoning evenly.

Load the Rotating Basket: Place the prepared frozen fries into the air fryer's rotating basket. Be sure not to overcrowd it; leave some space for air circulation. If your air fryer has a paddle or rotating function, this will help evenly cook and crisp the fries.

Set the Time and Temperature: Adjust the settings on your air fryer. For most frozen French fries, you'll want to cook them for 12-15 minutes at the preheated temperature. You can check the manufacturer's instructions for your specific brand and model.

Rotate or Shake (If Necessary): If your air fryer doesn't have a rotating basket, you may need to manually shake or rotate the basket halfway through the cooking time. This ensures that all sides of the fries get evenly cooked and crispy.

Check for Doneness: After the cooking time is up, check the fries for doneness. They should be golden brown and crispy. If needed, cook for an additional few minutes, but keep an eye on them to prevent overcooking.

Serve Hot: Once the frozen French fries are perfectly cooked, remove them from the air fryer, and serve them hot. You can enjoy them as a snack, side dish, or even with your favorite dipping sauces.
