Take your cleaned pumpkin seeds. Lay them on a single layer of a single pan lined with parchment for easier clean-up. Sprinkle with kosher salt to taste. Add any other seasoning you like.
Drizzle your favorite cooking oil on top.
Roast for 2 to 2 ½ hours until the seeds have browned and the outer shell has softerend.
If seeds are not brown but the shell is soft enough, then turn up the temperate to brown the seeds but be careful to watch them so you don't burn them.
