1. Preheat oven to 400.
2. Trim the ends off the butternut squash. Peel the squash until its bright-orange flesh shows (all green veins should be peeled off). Cut it in half horizontally. Then cut each half vertically. Scoop out and discard the seeds. Cut the squash into 3/4" cubes.
3. Toss the squash on a baking sheet with the melted butter, sugar, salt and pepper.
4. Roast in the oven for at least one hour, flipping the squash at the 30 minute mark and then again every 15-20 minutes. When the squash is done, it will be getting brown and caramelized at the edges.
