Preheat oven to 425F (220C). Line 2 baking sheets with parchment paper.
Peel and cut the sweet potatoes into ¼ inch (6mm) slices and then each slice into ¼ inch (6mm) sticks. Place the sticks into a large bowl.
Add cornstarch, garlic,basil, cumin, salt, pepper, Parmesan and toss to coat. Add oil and toss until all sticks are well coated.
Spread the sticks in a single layer into the prepared baking sheets.
Bake for 20-25 minutes,until golden brown and crisp, flipping the fries with a spatula after the first 15 minutes. If you bake the 2 sheets at the same time rotate after the first 15 minutes.
Serve warm and spread extra Parmesan if desired.
While the potatoes are baking prepare the dipping sauce. In a small bowl combine sour cream with mustard and chili sauce and set aside until ready to use.
