Preheat oven to 400 degrees.
Peel and cube squash. Place cubes on a large baking sheet lined with parchment paper.
Melt fat (if using a solid fat) and drizzle over squash cubes. Add salt and pepper and toss to coat so that all squash cubes are evenly coated.
Bake in the oven for 35-40 minutes or until golden brown to your liking. Toss every 10 minutes.
