1 (2 to 3 pound) butternut squash, peeled and seeded
2 tablespoons unsalted butter
1 medium onion, chopped
6 cups chicken stock

Bring to a simmer and cook until squash is tender, about 15 to 20 minutes. Remove squash chunks with slotted spoon and place in a blender and puree. Return blended squash to pot. Stir and season with nutmeg, cinnamon, salt, and pepper. Add brown sugar to taste. Serve.
