Preheat your oven to 400°F.
Cut the pumpkin. Start by cutting the bottom off of your pumpkin so that it lays flat on the cutting board. Don’t try to cut through the stem (it’s too hard and you’ll potentially end up hurting yourself). Starting at either side of the stem, with your hand steadying on the other half, carefully cut through the pumpkin halfway. Now do the same thing on the other side. It’s okay if it doesn’t line up, it doesn’t need to be perfect. Now put the knife down and pick up the bottom of the pumpkin and using your hands, pull the two halves apart.
Remove the seeds. Scoop out the seeds and the majority of stringy bits and set them aside. Lightly season the pumpkin halves with kosher salt and put on a lined baking sheet cut downside.
Bake. Bake for 45-55 minutes*. It’s done when a fork easily glides through.
Let cool. With a fork or spatula, carefully flip the pumpkin halves to let the steam escape and allow it to cool for a bit before scooping out the flesh.
Puree. The pumpkin will have some golden brown spots on the flesh, so don’t scrape those off (they’ll give it an even better flavor). For the smoothest consistency, add the pumpkin to the bowl of a food processor and blend until smooth.
