How to Make Loaded Fries in the Air Fryer: Air fryers are a great way to make crispy loaded fries with less oil. Preheat your air fryer to 400°F (200°C), arrange the seasoned potato sticks in an even layer, and air fry for 18-22 minutes, shaking the basket halfway through cooking. The result is crispy fries that are perfect for loading with your favorite toppings.
