Ingredients

3 pounds squash, such as butternut, orange Hokkaido, or buttercup, halved and seeded 

Canola oil, for baking sheet 

Preparation

Preheat oven to 400 degrees. Place squash halves, skin side up, on an oiled rimmed baking sheet. Bake until fork-tender, about 1 1/4 hours. Remove from oven. Turn over; let stand until cool enough to handle.

Scoop the flesh into a food processor, and discard skin. Puree until smooth. Refrigerate squash puree in an airtight container up to 4 days or store in the freezer up to 1 month.
