The Standard Turnip Portion: Root and Greens
For the turnip root, a common serving size is standardized at one cup of cubed raw turnip, which weighs approximately 130 grams (or 4.6 ounces). This portion provides a solid foundation for understanding its caloric and nutritional contribution to your meal. When selecting turnips, opting for smaller, younger roots is recommended, as they tend to be sweeter and less fibrous than larger, more mature ones.
The volume of turnips changes significantly during cooking. A study on portion conversions notes that 1 cup of raw, cubed turnip yields a little more than 3/4 cup once boiled. Likewise, starting with one pound (450g) of raw turnip cubes will result in about 2.5 cups once cooked.
Turnip greens, the leafy tops of the plant, are also highly nutritious and considered a separate portion. A standard serving is one cup of chopped turnip greens, which weighs about 55 grams raw. Due to significant shrinkage when cooked, you would need to start with the greens from 6 to 7 medium turnips to get one cup of cooked greens.

Practical Tips for Sourcing and Storage
To maximize freshness and flavor, select firm, smooth turnips with fresh-looking greens. Store the root and greens separately in the refrigerator to prevent the greens from drawing moisture from the root. The greens should be used within a few days, while the root can last for weeks when stored properly in a cool, dark, and dry place.

It also helps manage total daily calorie intake and promotes balanced meals featuring a variety of vegetables.
Cooking and Preparation Flexibility
The versatility of turnips means they can be a stand-alone side dish or an ingredient in more complex recipes. Use a vegetable peeler on larger turnips to remove the tougher skin, or leave the tender skin on smaller roots for added nutrients and texture. From roasting and mashing to pickling, there is a turnip preparation to suit every palate.
