Preheat your oven to 325 degrees Fahrenheit. This temperature is perfect for roasting the pumpkins, allowing them to soften properly.
Line your rimmed baking sheet with foil. This step is optional, but it can make cleanup easier and help capture any moisture that escapes while baking.
Wash the pumpkin thoroughly to remove any dirt or debris. This ensures that what you’re cooking is clean and safe to eat.
Cut off the top of the pumpkin using a sharp knife. Then slice it in half to expose the seeds and stringy innards.
Use a sturdy spoon to scoop out the seeds. It’s perfectly fine if some strings are left behind; they will not affect the final product.
Lay the pumpkin halves cut-side down on the baking sheet. Cover each half tightly with foil, which helps retain moisture during roasting.
Bake the pumpkin for about one hour. You’ll know it's ready when a fork easily pierces the flesh. Keep an eye on it to avoid overcooking!
Once done, let the pumpkin cool for about 30 minutes. This makes it easier to handle and safer to work with.
Peel the skin off the cooled pumpkin. Depending on the variety, the skin might come off easily, or you may need to scrape it away with a spoon.
Place the chunks of pumpkin flesh into your food processor or blender. Pulse or blend until it reaches a smooth consistency. If your pumpkin is a bit dry, you can add a teaspoon of water at a time to help it along.
Once blended, your Pumpkin Puree is ready to use! It can be used immediately or stored in an airtight container in the refrigerator for three to four days. You can also freeze it for several months.
