This recipe is from The Barefoot Contessa cookbook:
Caramelized Butternut Squash
Heat oven to 400.
Trim off the ends and cut into 1 1/2 inch cubes:
2 butternut squash
6 Tb unsalted butter
1/4 C light brown sugar
1 1/2 t kosher salt
1/2 t freshly ground black pepper
Combine with squash cubes and spread onto baking sheet.
40 to 55 minutes.
Very yummmy. Did I mention that I ate too much? I probably will never need to eat again.
