Oven-Baked Frites

Heat oven to 450 degrees. Place two baking sheets in oven. Peel potatoes; cut into 1/4-inch sticks. Place in a bowl; toss with olive oil, salt, and pepper. Carefully remove baking sheets from oven; coat with cooking spray. Divide potatoes between the hot baking sheets in a single layer. Bake, tossing occasionally, until golden brown, 20 to 30 minutes.
