For even cooking, choose potatoes that are similar in size. If you don't have fresh bay leaves, you can use dried bay leaves, but the flavor will be more intense. Use sparingly. Don't overcrowd the pan, as this will steam the potatoes instead of roasting them. If necessary, use two pans. For extra flavor, consider adding a sprinkle of grated Parmesan cheese during the last 10 minutes of roasting.
