Ingredients
Method
- Preheat oven to 250°F (120°C) and line two baking sheets with parchment.
- Slice the sweet potatoes lengthwise into ¼-inch strips (a mandoline helps).
- Arrange in a single layer and sprinkle lightly with cheese, if using.
- Bake 3 hours, flipping halfway, until dried and chewy.
- Cool completely before serving.
Notes
For chewier results, bake a little longer; for crispier, slice thinner. Cook time is hands-off.
