If you're looking for a healthier alternative to regular french fries, try making sweet potato fries in the Ninja Foodi air fryer. Sweet potatoes are packed with nutrients and have a natural sweetness that pairs well with the crispy texture achieved in the air fryer. Simply cut the sweet potatoes into thin strips, toss them with olive oil and your favorite seasonings, and air fry for about 15-20 minutes. The result is a delicious side dish or snack that is both tasty and nutritious.
