The world of vegetables is vast and varied, with many plants being confused with one another due to their similarities in appearance or taste. Two such vegetables that often get mixed up are kohlrabi and turnip. While they may look alike and belong to the same plant family, they are distinct vegetables with their own unique characteristics, uses, and nutritional profiles. In this article, we will delve into the differences and similarities between kohlrabi and turnip, exploring their history, culinary uses, nutritional benefits, and how to incorporate them into your diet.
Introduction to Kohlrabi and Turnip
Kohlrabi and turnip are both members of the Brassica family, which includes other popular vegetables like broccoli, cauliflower, and cabbage. This family is known for its cruciferous vegetables, which are characterized by their four-petaled flowers that resemble a cross. Despite their shared family ties, kohlrabi and turnip have distinct growth habits, appearances, and flavors.
History and Origin
Kohlrabi is believed to have originated in Europe in the 16th century, where it was widely cultivated and consumed. Its name is derived from the German words “kohl,” meaning cabbage, and “rabi,” meaning turnip. This vegetable was highly valued for its unique taste and nutritional properties, quickly spreading throughout the continent and eventually around the world.
Turnip, on the other hand, has a longer history that dates back to ancient times.

How Do I Identify Kohlrabi in the Market or Grocery Store?
When shopping for kohlrabi, look for a vegetable with a bulbous stem and leaves that resemble those of a turnip. The skin should be smooth and firm, with a light green or purple color depending on the variety. The leaves should be fresh and crisp, with no signs of wilting or yellowing. Avoid kohlrabi with soft or bruised skin, as this can be a sign of age or damage. You can also ask your grocer or farmer if they have kohlrabi in stock, as it may be labeled as “kohlrabi” or “German turnip”.
Kohlrabi is often displayed in the produce section of grocery stores, near other vegetables like broccoli and cauliflower. It may also be found at farmers’ markets, where it is often sold in bunches with the leaves attached. When selecting kohlrabi, choose one that feels heavy for its size and has a fresh, earthy aroma.

Can I Use Kohlrabi and Turnip Interchangeably in Recipes?
While kohlrabi and turnip are similar in appearance and flavor, they are not entirely interchangeable in recipes. Kohlrabi has a milder flavor and crunchier texture than turnip, making it better suited to raw or lightly cooked dishes. Turnip, on the other hand, has a stronger flavor and is often used in cooked dishes where its flavor can shine through. If you substitute kohlrabi for turnip in a recipe, you may need to adjust the cooking time and seasoning to get the best flavor and texture.
That being said, there are some recipes where kohlrabi and turnip can be used interchangeably. For example, in soups or stews where the vegetables will be cooked until tender, either kohlrabi or turnip can be used. In these cases, the flavor and texture differences between the two vegetables will be less noticeable. However, in dishes where the vegetables will be eaten raw or lightly cooked, it’s best to use the specific vegetable called for in the recipe to get the best flavor and texture.
How Do I Store Kohlrabi to Keep it Fresh?
To keep kohlrabi fresh, store it in the refrigerator as soon as possible after purchase. Remove any leaves or stems that will be trimmed before cooking, and wrap the kohlrabi in plastic wrap or aluminum foil to prevent moisture loss. Store the kohlrabi in the crisper drawer of the refrigerator, where it will keep for up to a week. Do not wash the kohlrabi before storing, as excess moisture can cause it to become soggy or develop off-flavors.
For longer-term storage, kohlrabi can be blanched and frozen. To do this, trim the leaves and stems from the kohlrabi and slice or chop it into desired shapes. Blanch the kohlrabi in boiling water for 2-3 minutes, then chill it in an ice bath to stop the cooking process. Once chilled, pack the kohlrabi into airtight containers or freezer bags and store in the freezer. Frozen kohlrabi will keep for up to 6 months and can be used in soups, stews, and other cooked dishes.
