tsp sweet Hungarian paprika
Preheat oven to 425°F. Line a baking sheet with aluminum foil (preferably the easy release kind).
Peel the sweet potatoes. Cut each potato in half, and then into quarters. Then, slice into fry shapes, about 1/2 inch wide.
Place the sweet potatoes into a resealable plastic bag. Add oil, salt, paprika and cinnamon. Seal the bag and shake well to thoroughly coat the fries. Spread the potatoes out onto the baking sheet in a single layer.
Cook for 30 minutes, turning every 10 minutes, until slightly browned. Serve warm.
