1Heat oven to 425°F. Line cookie sheet with cooking parchment paper and spray paper with cooking spray, or line with silicone baking mat.
2Cut squash widthwise into 1-inch slices. Cut slices into thin strips to look like French fries; place on cookie sheet. Sprinkle with salt and pepper.
3Bake about 50 minutes, turning over halfway through baking, until fries are deep golden brown and mostly crispy. Serve warm.
