Prep. Preheat the oven to 300 degrees F and line a baking pan with parchment paper.
Clean. If you are using fresh pumpkin seeds, rinse them of their pulp and dry them thoroughly. If you are using store-bought seeds, you can skip this step.
Make the spice mixture. Whisk together the honey, Worcestershire, salt, pepper, chili powder, cinnamon, nutmeg, and brown sugar.
Season. Toss the pumpkin seeds with the olive oil mixture to coat and then with the spice mixture.
Bake. Sprinkle the seasoned seeds in an even layer over the prepared baking sheet. Bake for 50 minutes or until golden brown. Give the seeds a stir every 15 minutes or so.
Notes
If you’d like to make a sweet snack instead, boil the seeds with sugar rather than salt, and at the seasoning stage, add sugar or brown sugar, cinnamon, etc.
