Step 1: Preheat your oven to 300 degrees.
Step 2: Separate the pumpkin seeds from the stringy insides. It’s best to do this while the seeds and the pumpkin guts are soaking in water. The seeds float, and the stringy stuff doesn’t.
Step 3: Thoroughly wash the seeds to remove all the pulp and debris. Dry them off fairly well.
Step 4: Lightly grease a baking tray with vegetable oil and spread the seeds out in a single layer. One tablespoon of oil is enough for the whole sheet.
Step 5: Bake for about 40 minutes, turning the seeds every 5 minutes or so. You don’t have to turn each seed individually, just scoop them up and flip a whole spoonful at a time.
Step 6: Once they’re lightly browned, they ready to be removed. Allow the seeds to cool before serving.
