Kohlrabi, often mistaken for a root vegetable, is actually the swollen stem of a member of the cabbage family. This versatile and nutritious food can be a fantastic addition to your diet, whether you prefer it raw or cooked. Both methods offer distinct flavor and texture profiles, making kohlrabi a truly flexible ingredient in the kitchen. To decide which preparation is best for you, it's helpful to understand the differences and learn how to prepare it for each method.
The Raw Appeal: Crispness and Flavor
Eating kohlrabi raw is perhaps the simplest way to enjoy its unique characteristics. The raw bulb has a crisp, juicy texture similar to a radish or apple, with a mild, slightly peppery, and sweet flavor. When preparing kohlrabi for raw consumption, it's crucial to peel away the tough outer skin with a sharp knife. Once peeled, you can prepare it in several ways:
- Thinly Sliced: Use a mandoline for paper-thin slices to add a crunchy element to salads and sandwiches.
- Matchsticks: Cut the kohlrabi into matchsticks for an easy-to-snack-on treat or to add to slaws.
- Grated: Grate it and mix with shredded carrots, apples, and a light dressing for a refreshing slaw.
The tender leaves of young kohlrabi are also edible raw, adding a slightly pungent, peppery flavor to salads. The raw preparation method retains the maximum amount of heat-sensitive nutrients like vitamin C.
The Cooked Comfort: Tender and Mellow
When kohlrabi is cooked, its character changes completely. The crispness gives way to a tender, potato-like softness, and its flavor becomes milder and sweeter. Cooking also allows kohlrabi to absorb other flavors beautifully, making it an excellent base for a variety of dishes.
Here are some popular cooking methods:
- Roasting: Roasting kohlrabi cubes with olive oil, salt, and pepper brings out its natural sweetness, creating a caramelized exterior and a tender interior.
- Sautéing: Sauté sliced or diced kohlrabi with garlic, butter, or herbs for a simple yet delicious side dish.
- Soups and Stews: Adding chunks of kohlrabi to soups and stews lets it simmer and soften, absorbing the rich flavors of the broth.
- Mashed: Boiling and mashing kohlrabi is a great, low-carb alternative to mashed potatoes.
Preparing Kohlrabi for Cooking
- Remove Greens and Stems: Cut away the leaves and stems from the bulb. Store the bulbs and leaves separately in the refrigerator.
- Peel the Bulb: Use a sharp knife to remove the fibrous, tough outer skin. A vegetable peeler may struggle with the thick skin, so a knife is often more effective.
- Cut as Desired: Depending on your recipe, dice, slice, or cube the kohlrabi. For faster cooking, thinner pieces are ideal.

Kohlrabi's underrated status is a missed opportunity for many home cooks. Its flexibility and mild flavor profile make it a fantastic and fun vegetable to experiment with. From a simple raw slaw to a rich and creamy soup, kohlrabi can adapt to almost any flavor profile you throw at it. For those looking to eat healthier, kohlrabi's nutritional benefits—including being an excellent source of fiber and antioxidants—make it a smart choice. Whether you are a fan of its crisp, raw bite or prefer the tender, mellow comfort of a cooked dish, there is no wrong way to enjoy this unique vegetable. Embrace the adventure and give kohlrabi a try in both forms to discover your favorite preparation.
Conclusion: Your Preference Dictates the Method
So, should kohlrabi be cooked? The simple answer is that you don't have to, but you certainly can. Your cooking method should depend on the texture and taste you desire for your dish. For a refreshing crunch and a hint of peppery spice, eat it raw. For a softer, sweeter flavor that blends well with other ingredients, cook it. The great news is that you don't have to choose just one; its versatility allows you to enjoy kohlrabi in a multitude of ways, unlocking its full culinary potential for a wide range of meals, from quick snacks to hearty dinners.
