Preheat your oven to 375 degrees f. and line a large baking sheet with parchment paper or a silicone mat.
Arrange your chopped pumpkin, in a single layer onto the tray.
Roast for about 30 minutes, or until fork tender.
Remove from the oven and allow it to cool.
Transfer the cooked pumpkin to a food processor or high speed blender and process until almost smooth.
Place pumpkin in strainer and allow it to drain all excess liquid for up to 2 hours.
Store any extra pumpkin puree that you're not using right away in 1 cup portions inside of reusable freezer bags or freezer safe storage containers. Be sure to label with the date.
Freeze for up to 3 months.
Enjoy!
