Pumpkin seeds roast more quickly at a higher temperature. Using smaller seeds also reduces the roasting time. The seeds are ready when they are golden brown and crunchy. A basic recipe for roasted pumpkin seeds involves tossing the seeds with olive oil, salt and pepper before spreading them on the baking sheet in a single layer. Cooks can impart extra flavor to the pumpkin seeds by adding herbs, spices and other seasonings. A recipe on SimplyRecipes.com also suggests that boiling the seeds in salted water prior to the roasting process improves the taste of the final product.
