The parsnip (Pastinaca sativa) is a root vegetable.

The parsnip is native to Eurasia; it has been used as a vegetable since antiquity. It was cultivated by the Romans. It was used as a sweetener before the arrival in Europe of cane sugar.

The plant is closely related to carrot and parsley; all belong to the family Apiaceae. Its long, tuberous root has cream-colored skin and flesh. Left in the ground to mature, it becomes sweeter in flavor after winter frosts.
