Clean the Seeds: Rinse the pumpkin seeds under cool water, removing any stringy pumpkin bits. Pat dry thoroughly with a clean towel.
Preheat & Prep: Preheat the oven to 325°F. Line a baking sheet with parchment paper and set aside.
Toast the Seeds: In a skillet over medium heat, combine the pumpkin seeds and olive oil. Cook for about 3 minutes until the seeds begin to look lightly golden. They will continue to darken in the oven.
Add Sweetener: Stir in the honey and ground cinnamon if using.
Bake: Spread the seeds into an even layer on the prepared baking sheet. Bake for 30 minutes, stirring every 5 to 10 minutes to prevent sticking.
Season & Cool: Remove from the oven and sprinkle with flaky sea salt if desired. The seeds may look slightly sticky at first but will dry and crisp as they cool within a few minutes.
Store: Once completely cooled, store in an airtight container.
Notes
Pre Toasting: Toasting the seeds in a skillet before baking helps remove excess moisture and ensures a crisp texture.
Color Change: Do not aim for deep browning on the stovetop. The oven will finish the roasting process.
Texture Check: Seeds may appear wet when first removed from the oven but will dry and retain their shine as they cool.
Storage: Properly stored in an airtight container at room temperature, pumpkin seeds can last several weeks. Moisture exposure will shorten shelf life.
