Preheat oven to 425 degrees.
Bring a large stockpot of water to a boil. Place potatoes in pot and boil for about 6-8 minutes or until al dente. Don't let them go too long here or they won't be firm enough to hold their shape.
Drain potatoes and then dry with paper towels. Make sure that they are very dry or they won't crisp up.
Mix remaining ingredients in medium-sized bowl. Place potatoes in the mixture and coat evenly.
Spread sweet potatoes on a cookie sheet. Use two cookie sheets if necessary to prevent potatoes from touching. (If the fries touch, the potatoes will steam instead of roast.)
Place potatoes in oven for 30 minutes or until golden and crispy, turning them occasionally.
Remove and serve with Chipotle Dipping Sauce.
