Set pumpkin cut-side down on a baking sheet, and roast 40-50 minutes or until tender.
Remove pumpkin from the oven, scoop the pumpkin out, and discard the skin. Tip: If a little bit of skin ends up in the purée, it's okay. It's edible.
Skip the Blender (Option 1):If you're eating the pumpkin as a side dish, adding it to a dish that will be puréed after adding the pumpkin, or adding it to a dish where it doesn't matter if the pumpkin is silky smooth, you can stop here.Blend the Pumpkin (Option 2):For extra-smooth pumpkin purée, add the pumpkin to a blender or food processor. If your blender struggles, add a splash of water while blending, but you shouldn't need to!
