For a healthier twist on traditional French fries, try making them with sweet potatoes. Cut the sweet potatoes into fries and toss them with olive oil, salt, and cinnamon. The air fryer will cook them until they are crispy on the outside and tender on the inside. These sweet potato fries are packed with flavor and make a great side dish or snack. Serve them with a sprinkle of brown sugar or a drizzle of maple syrup for an extra touch of sweetness.
