Prep your oven by moving the wire racks to the middle of the oven. Be sure to test that the pumpkin(s) will fit before pre heating.
Preheat your oven to 350 degrees. Place whole pumpkin(s) on a sheet pan with either a silicone mat or parchment paper.
Place pumpkin(s) in the oven and bake until knife tender. Anywhere from 30 minutes to 2+ hours.
While pumpkin(s) are baking, prep your processing area with a blender, large bowl, cutting board and a sharp knife.
After pumpkin(s) are done, place on a cutting board and cut the top in a square shape to remove the stem. Scoop out insides in a bowl. (Keep seeds for roasting later)
Once the pumpkin(s) are clear on the inside, quarter them.
Scoop the insides out with a spoon into the blender. Once all the pumpkin is out, purée in your blender until completely smooth
