For a healthier twist, try making air fryer french fries using sweet potatoes. Peel and cut the sweet potatoes into thin strips, then toss them with olive oil, paprika, cinnamon, salt, and pepper. Preheat the air fryer to 400°F (200°C) and cook the fries in a single layer for 15-20 minutes, shaking the basket occasionally. These sweet and savory fries are a delicious alternative to traditional french fries.
