The parsnip (Pastinaca sativa, family Apiaceae) is a root vegetable related to the carrot, which it resembles, although it has a paler color and a stronger flavor. The parsnip has greater nutritional value than any vegetable except the potato. Like carrots, parsnips are native to Europe and have been eaten since ancient times. Parsnips can be boiled, roasted or used in stews, soups and casseroles.
