Preheat the oven to 400 degrees. Slice the potatoes into wedges. Start by scrubbing the potatoes. Then slice in half lengthwise and slice in half again. Then carefully cut each side into thin wedges.
Bake for 35 minutes, flipping after 25 minutes. Only flip the potatoes is they are browned and crispy on the bottom and easily release from the pan. If they stick at all, they aren't ready to be flipped.
