Preheat the oven to 375 degrees fahrenheit and line a 9x13 baking sheet with parchment paper.
Remove the stem from the pumpkin and slice the pumpkin half, length wise (from top to bottom).
Place the pumpkin halves on the pan with skin side up and the inside of the pumpkin down. This allows it to cook more evenly.
Bake for 45 minutes then remove from the oven and let rest, untouched, for 10 minutes.
Scoop the meat out of the pumpkin and smash it with a fork or place it in a blender, until there’s no large chunks.
Use immediately or store in an airtight container, in the fridge, for up to 1 week. Freeze in an airtight container for up to 3 months.
