Preheat oven to 450 degrees.
Carefully cut potatoes into 1/4-1/2? thin strips, or to desired thickness and length. Place in a large bowl, and toss with remaining ingredients (oil and spices) until potatoes are evenly coated.
Spread potatoes evenly on baking sheet prepared with parchment paper or silicone baking sheet. (Try not to overcrowd the sheet, or have multiple layers of fries - you want them to be roasted, not steamed.)
Place in oven and cook for 20-25 minutes, turning the fries once or twice during that time to cook evenly. (May take more or less time, depending on size and thickness.) Remove once edges begin to brown and fries begin to crisp.
