Preheat oven to 325°F.

Using a serrated knife, cut the pumpkin in half. Using a large spoon remove all of the seeds and fibers.

Cover with aluminum foil and place on baking sheet, foil side up. Bake 1 hour or until tender.

Let cool. Scrape pumpkin flesh from the shell and puree in a food processor (or blender). Process until the flesh is smooth, about 4-5 minutes.
