Arrange the frozen fries in an even layer in the air fryer basket.
Cook for 5 minutes. Remove the basket with the fries and shake to thoroughly toss the fries for even heating. Return fries to the air fryer and cook for 4 to 9 minutes or until crispy outside and fluffy inside.
Season to taste with seasoned salt, if using. Or, you can season to taste with fine kosher salt, if you prefer.
