Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
Scoop the seeds from your pumpkin, place them in a colander, and rinse under cold water to remove pulp.
Spread the cleaned seeds on a towel and pat completely dry.
In a mixing bowl, combine the seeds, olive oil, salt, and chosen seasonings. Toss until evenly coated.
Arrange the seeds in a single layer on the baking sheet.
Bake for 30–40 minutes, stirring halfway through, until golden brown and crisp.
Allow seeds to cool completely before serving or storing.
