Air-fried french fries are best right out of the frier. They are crisp on the outside and soft inside, like the perfect french fry. Unlike french fries, the delicate potato flavor really comes though rather than oil. If seasoned well, these fries are so good, they don't need to be dipped in ketchup. Serve them with your favorite meat, like rotisserie chicken, burgers, or grilled steak.
