Gather all ingredients. Preheat the oven to 425 degrees F (220 degrees C).

Use a sharp knife to carefully cut away the peel from the squash. Cut the squash into sticks, about 1/3 inch thick.

Blot any moisture from the butternut squash fries with paper towels, then arrange squash pieces on a baking sheet. Season with salt.

Bake in the preheated oven until brown and crisp on the edges, about 20 minutes, turning once.
