For this recipe, you will need 1 cup of raw whole pumpkin seeds, 2-3 teaspoons melted butter and a pinch of salt. Preheat the oven to 300 degrees Fahrenheit or 150 degrees Celsius. Toss the whole pumpkin seeds in a bowl with the melted butter and salt. Spread the seeds on a single layer of a baking sheet and bake for 45 minutes or until golden brown. Stir the seeds occasionally to allow for even browning.
