Remove the stem of the pumpkin and slice it in half.
Scoop the seed and fiber with a metal spoon or ice cream scoop.
Sprinkle the pumpkin flesh with salt and place the halves, skin side up, on parchment paper-lined baking sheets.
Roast until you can easily pierce through the skin with a knife or for 40 minutes.
Let cool completely for 1 hr before scooping the flesh from the skin into a blender or food processor. If using a food processor, process until fully smooth for about 4 minutes.
Notes
You can store it in the fridge for up to 1 week or in the freezer for 3 months.
