Preheat your oven to 350°F and line a baking sheet with parchment paper.
If you’re using salt, rinse the pepitas in a mesh strainer and allow any excess water to drain. (Skip this step if you’re not using salt.)
Spread the pepitas on the parchment-lined baking sheet in a single layer, making sure to break up any clumps that are stuck together.
Sprinkle with salt, if using. Start with ⅛ teaspoon and add more if you like them extra salty like I do.
Roast for 10 minutes. Take them out of the oven and give them a stir/shake. Roast for another 5-7 minutes, until the pepitas are a nice golden color, but not too dark.
Cool the pepitas completely before storing them in an airtight container at room temperature.
Add roasted pepitas to salads or soups for a crunchy topping, or eat them as a snack.
