Once the air fryer has been preheated, lightly spray the inside basket with non-stick cooking spray.
Add the French fries to the basket and spread out evenly with tongs.
Cook for 10 minutes. Open the basket and shake the fries to turn them. Cook for an additional 10 to 15 minutes more, checking after every 5 minutes to shake the fries and check for doneness.
Serve immediately with ketchup, mayo, or other sauces.
Notes
You can substitute seasoning salt instead of table salt.
