Coat a large baking sheet with non-stick cooking spray. Spread the sliced potatoes on the baking sheet in one layer. Be sure not to overlap the potatoes.
Bake the fries for 25 minutes at 425°F. Then, flip the fries over with a spatula, and raise the oven temperature to 500°F. Bake an additional 10 minutes, or until golden and crisp.
