Preheat the Air Fryer to 400 degrees Fahrenheit/200 degrees Celsius.
Place the fries in a single layer into the air fryer basket and then spray a light coat of oil and then season with salt.
Air fry frozen french fries at 400 degrees F for 10 minutes, shake the fries, and then cook for an additional 8-10 minutes cooking time, depending on how crispy you like your fries.
Notes
In an airtight container, crisp air fryer french fries can be stored in the refrigerator for 3 to 4 days. To reheat, simply put them back in the air fryer at 350 degrees for 6 to 8 minutes or until they are nice and crispy again. I do not suggest refreezing already cooked french fries.
