The parsnip is a root vegetable closely related to the carrot and parsley. It is a biennial plant usually grown as an annual. Its long, tuberous root has cream-colored skin and flesh; and left in the ground to mature, it becomes sweeter in flavor after winter frosts.
Half a cup of sliced, cooked parsnips has 3 grams of fiber and only 55 calories. They are a good source of vitamin C (11% of the recommended daily allowance), folate (11%), and manganese (10%). It's no coincidence that the parsnip resembles the carrot.
