Step 1Heat oven to 425 degrees.
Step 2Cut the potato in half lengthwise, then cut each half into 7 long, thin wedges. Place them on a rimmed baking sheet and toss them with the oil and salt and pepper to taste, so all sides are coated.
Step 3Bake 10 minutes. Flip the potatoes over and bake another until tender, another 8 to 10 minutes. Serve hot.
