Preheat the oven to 450 degrees.
Carefully cut the potatoes into 1/4″ thin strips, or to your desired thickness and length. Then place in a large bowl, and toss with the remaining ingredients (oil and spices) until potatoes are evenly coated.
Then spread out the potatoes evenly on a 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 the size and thickness you cut the fries.) Remove once the edges slightly begin to brown and fries begin to crisp.
