Sweet potato fries are a healthier alternative to regular fries and can be easily made in an air fryer. Start by cutting the sweet potatoes into thin strips or wedges. In a bowl, toss the sweet potato strips with olive oil, salt, and your choice of seasonings (such as paprika, garlic powder, or cinnamon). Place the seasoned sweet potato strips in the air fryer basket and cook at 400°F for about 15-20 minutes, or until they are crispy and golden brown. Serve these sweet potato fries as a side dish or a snack.
