Preparation
Preheat oven to 450 F.
Cut the potatoes lengthwise into 10 to 12 even-sized wedges. Place them in a large bowl and toss with the oil.
Spray a baking sheet with cooking spray and place the potatoes on the tray in a single layer. Bake for 20 minutes. Use a metal spatula to scrape the wedges from the pan and turn them over with a fork or tongs, keeping them in a single layer. Bake for 15 minutes longer, or until golden and crisp. Season with salt to taste.
