- Prepare the sweet potatoes: In a small bowl, combine cumin, salt, and pepper. Set aside. Preheat oven to 400 degrees F. Peel potatoes, cut each in half lengthwise, and cut each half into 6 wedges. In a large bowl, combine the cut potatoes, oil, and spice mixture. Toss until potatoes are evenly coated.
- Bake the fries: On a baking sheet, arrange potatoes in a single layer and place on the middle shelf of the oven. Bake until edges are crisp and potatoes are cooked through — about 30 minutes. Serve immediately.
