Parsnips and turnips, two root vegetables often found nestled side-by-side in the produce section, can easily be mistaken for one another. Their pale coloration and similar shapes contribute to this confusion. However, despite their visual similarities, these vegetables boast distinct flavors, textures, and nutritional profiles. This article delves into the nuances of parsnips and turnips, exploring their origins, characteristics, culinary uses, and health benefits, to help you confidently distinguish between these earthy delights.
A Root-Level Look: Origins and Botany
Understanding the botanical backgrounds of parsnips and turnips provides a solid foundation for appreciating their differences.
Parsnip Pedigree: A Sweet History
The parsnip, scientifically known as Pastinaca sativa, belongs to the Apiaceae family, which also includes carrots, celery, and parsley. Its origins trace back to Eurasia, where it was cultivated by the ancient Romans and Greeks. Parsnips were a staple food in Europe before the arrival of the potato from the Americas. They were valued for their sweetness and ability to thrive in colder climates. Parsnips are biennials, meaning they typically require two growing seasons to complete their life cycle, although they are usually harvested in the first year for their roots.
Turnip Tales: An Ancient Crop
Turnips, classified as Brassica rapa, are members of the Brassicaceae family, a group renowned for its cruciferous vegetables, such as cabbage, broccoli, and kale. Turnips also have ancient roots, with evidence of their cultivation dating back to prehistoric times in both Europe and Asia. They were a common food source for both humans and livestock. Turnips are annuals or biennials and are known for their rapid growth, making them a reliable crop for diverse climates.
Sensory Showdown: Appearance, Taste, and Texture
The most immediate way to differentiate parsnips and turnips is through your senses.
Visual Verdict: Shape and Color
While both are root vegetables, their appearances offer clues to their identities. Parsnips generally have a long, tapered shape, resembling carrots but with a cream or ivory-colored skin. The shoulder, or top, of the parsnip is typically wider than the root. Turnips, on the other hand, are more spherical or globe-shaped. Their color varies depending on the variety. Some turnips are entirely white, while others have a purple, red, or green top where they were exposed to sunlight. The size is also a tell. Parsnips are generally longer and thinner than turnips.
Taste Test: Sweet vs. Peppery
The flavor profiles of parsnips and turnips are distinct and contribute significantly to their culinary applications. Parsnips have a sweet, slightly nutty, and earthy flavor that intensifies after exposure to frost. This sweetness makes them a popular addition to soups, stews, and roasted vegetable medleys. Turnips offer a more pungent and slightly bitter taste, especially when raw. Cooking mellows the flavor, making it milder and sweeter. The peppery notes are more pronounced in larger, older turnips. Parsnips are almost always sweeter than turnips.
Textural Territory: Smooth vs. Coarse
The texture of these root vegetables also differs. Parsnips, when cooked, have a smooth, creamy texture that makes them ideal for purees and mashes. Turnips, depending on their size and age, can have a slightly coarser texture. Younger turnips are more tender, while older ones can be fibrous. Cooking turnips thoroughly softens them. Parsnips tend to be smoother and less fibrous than turnips after cooking.
Culinary Crossroads: Cooking and Serving Suggestions
Both parsnips and turnips are versatile vegetables that can be prepared in a variety of ways.
Parsnip Possibilities: Sweet and Savory Delights
Parsnips are often roasted, mashed, pureed, or added to soups and stews. Their sweetness pairs well with savory flavors like thyme, rosemary, and garlic. They can also be used in sweet dishes, such as cakes and breads, adding moisture and a subtle sweetness. Parsnip fries are a delicious alternative to potato fries. Roasting parsnips brings out their natural sweetness and creates a caramelized exterior. Parsnip soup is a classic dish, offering a creamy and comforting experience.
Turnip Transformations: From Bitter to Bliss
Turnips can be boiled, steamed, roasted, mashed, or even eaten raw when young and tender. Their peppery flavor complements other root vegetables and hearty meats. Turnip greens are also edible and can be cooked like other leafy greens, such as spinach or kale. They offer a slightly bitter and peppery taste. Mashed turnips are a healthy and flavorful alternative to mashed potatoes. Adding a touch of sweetness, such as maple syrup or brown sugar, can balance the bitterness of turnips. Turnip greens are often sautéed with garlic and olive oil for a simple and nutritious side dish.
Nutritional Nuggets: Health Benefits Unveiled
Both parsnips and turnips offer a range of health benefits due to their nutrient content.
Parsnip Power: Vitamins and Minerals
Parsnips are a good source of vitamins C and K, as well as folate and potassium. They are also high in fiber, which aids digestion and promotes a feeling of fullness. The antioxidants in parsnips can help protect against cell damage. Parsnips are particularly rich in soluble fiber, which can help lower cholesterol levels. Their vitamin K content is important for blood clotting and bone health.
Turnip Treasures: Fiber and Glucosinolates
Turnips are low in calories and high in fiber, making them a good choice for weight management. They are also a good source of vitamin C, potassium, and calcium. Turnips contain glucosinolates, compounds that have been linked to cancer prevention. Turnips are a good source of glucosinolates, which are broken down into beneficial compounds during digestion. Their high water content contributes to hydration.
Selection and Storage Strategies
Knowing how to select and store parsnips and turnips ensures you enjoy them at their best.
Parsnip Picks: Choosing Quality
When selecting parsnips, look for firm, smooth roots that are free from blemishes or soft spots. Smaller parsnips tend to be sweeter and more tender than larger ones. Avoid parsnips that are overly large or have a woody texture. Smaller parsnips are generally more flavorful and less fibrous. Store parsnips in the refrigerator in a plastic bag for up to 2 weeks.
Turnip Tactics: Finding Freshness
Choose turnips that are firm and heavy for their size. Smaller turnips are typically more tender and sweeter. If buying turnips with greens attached, make sure the greens are fresh and vibrant. Avoid turnips that are soft, shriveled, or have cracks. Smaller turnips are usually milder in flavor and more tender. Store turnips in the refrigerator in a plastic bag for up to 1 month. Turnip greens should be stored separately and used within a few days.

The greens of the turnip, known as turnip greens, are also edible and can be sautéed or added to soups for a nutritious and slightly bitter flavor.
How do you properly store parsnips and turnips to maintain freshness?
To store parsnips, remove the green tops, as they draw moisture from the root. Place the parsnips in a plastic bag in the refrigerator’s crisper drawer. This will help maintain humidity and prevent them from drying out. Properly stored parsnips can last for several weeks.
Similarly, remove the greens from turnips before storing. Turnips can be stored in a plastic bag in the refrigerator’s crisper drawer. If the turnips are small and tender, they can last for a week or two. Larger, more mature turnips tend to have a longer shelf life, sometimes lasting for several weeks if stored properly.
Can both parsnips and turnips be grown in the same garden environment?
Yes, both parsnips and turnips can be successfully grown in the same garden environment, as they have similar requirements. They both prefer well-drained soil that is rich in organic matter. Full sun is ideal, although they can tolerate partial shade, especially in hotter climates.
However, it’s important to practice crop rotation to avoid depleting the soil of specific nutrients and to minimize the risk of pests and diseases. Ensure sufficient space between plants for proper growth, as overcrowding can lead to smaller, less developed roots. Consistent watering is also essential, especially during dry periods.
