How to Make It
Preheat the oven to 400°. Line a baking pan with parchment paper.
Bring a pot of salted water to a boil. Add the seeds and boil for 10 minutes. Drain. Pat the pumpkin seeds dry on paper towels.
In a bowl, toss the pumpkin seeds with the vegetable oil, brown sugar, and rosemary. Season with salt to taste. Spread the coated seeds evenly on the lined baking pan. Roast for 20-25 minutes, turning the seeds every 10 minutes. Remove the seeds from the oven when they are crispy. Allow to cool to room temperature and serve.
