Preheat oven to 350 degrees
Separate seeds from pumpkin. It is fine for a little pumpkin to be mixed in with the seeds. Do not wash or clean the seeds.
Add 1/2-1 tbsp of melted butter for every 1 cup of seeds. Mix.
Add salt to taste. Mix.
Spread seeds in a single layer on a baking sheet.
Bake for 15 minutes then flip seeds over. Bake for an additional 10-12 minutes or until the seeds are nicely browned and crisp.
