How long it keeps
- Refrigerator: 3 to 4 days, as for cooked leftovers (USDA).
- Freezer: pack in rigid containers, leaving ½ inch of space at the top of a pint, and freeze up to 8 to 12 months for best quality (NCHFP). Freeze it in 1¾-cup portions, one can’s worth each.
Nutrition
Roasted pumpkin without the skin and seeds is close to canned pumpkin, so the numbers are USDA’s for canned pumpkin.
Steps
You’ll need: large sharp knife, sturdy spoon, rimmed baking sheet lined with parchment, food processor or blender, fine strainer or cheesecloth (helpful).
- Heat the oven to 400°F. Wash the pumpkin, set it on a damp towel so it can’t roll, and cut it in half from the stem down. Scrape out the seeds and strings (save the seeds to roast).
- Brush the cut sides lightly with oil if you like and lay the halves cut side down on the lined baking sheet.
- Roast 45 to 60 minutes, until a knife slides easily through the skin and the flesh is very soft.
- Cool until you can handle it, then scoop the flesh away from the skin.
- Purée in a food processor or blender until smooth.
- For pie, it should be as thick as canned pumpkin. If it looks wet, set it in a strainer lined with cheesecloth or a coffee filter over a bowl in the refrigerator for 1 to 2 hours, or stir it in a wide pan over low heat until thick.
- Cool in shallow containers and refrigerate within 2 hours.
⚖️ ScalingOne pumpkin per batch. Two pie pumpkins fit on one large baking sheet.
🛡 SafetyHome canning of mashed or puréed pumpkin isn’t recommended (NCHFP); freeze it instead.
Good to knowBig carving pumpkins are stringy and watery. Look for pumpkins sold as pie or sugar pumpkins, 2 to 5 lb.
Good to knowButternut squash makes a smooth purée the same way and works in any pumpkin recipe.
