Kohlrabi and cabbage are two cruciferous vegetables that often find their way into our salads, stir-fries, and various culinary delights. On the surface, they may appear similar due to their leafy green looks, but upon closer inspection, their differences become clear. This article delves into how kohlrabi differs from cabbage in aspects such as appearance, nutritional profile, taste, culinary uses, and more.
Understanding the Basics: What are Kohlrabi and Cabbage?
Before dissecting the differences, it’s essential to understand what we’re comparing.
Kohlrabi: An Uncommon Vegetable
Kohlrabi, often referred to as a “turnip cabbage,” is a member of the Brassica oleracea species, much like cabbage. This fascinating vegetable has a swollen stem that can be purple, green, or white, providing a unique bulbous appearance. The part we commonly consume is the swollen stem, while the leaves can also be eaten, often likened to kale or collard greens.
Cabbage: A Staple in Many Diets
Cabbage, on the other hand, comes in various hues and types, including green, red, and Savoy cabbage. It consists of tightly packed leaves, forming a dense head. Cabbage is a core ingredient in numerous dishes worldwide, from coleslaw to kimchi, known for its versatility and health benefits.
Visual Differences: Appearance Matters
One of the most striking differences between kohlrabi and cabbage is their appearance.
Kohlrabi’s Unique Structure
The kohlrabi’s distinctive bulb sits above the ground, making it easy to identify. The vegetable has a smooth, round shape with thick stems protruding from the top that form clusters of leaves. Its skin can be smooth and glossy, appearing in various shades, including pale green, white, and purple.
The Cabbage Head
Cabbage, in contrast, forms a compact, round or oval head composed of layers of tightly packed leaves. The leaves may be crinkly, as in Savoy cabbage, or smooth, as in green cabbage. Its robust structure and bulk make it visually different from kohlrabi, which is more bulbous and top-heavy.

What is the main difference between kohlrabi and cabbage?
Kohlrabi and cabbage are both members of the Cruciferae family, but they differ significantly in their appearance and growth habits. Kohlrabi is known for its swollen, bulb-like stem that can be green or purple, and it grows above the soil. In contrast, cabbage develops a tightly packed cluster of leaves, known as a head, which grows directly from the ground. This structural difference influences how they are harvested and prepared in the kitchen.
In terms of flavor, kohlrabi has a mild, slightly sweet taste, often compared to a cross between a turnip and a radish. Cabbage, on the other hand, has a more robust flavor that can vary from sweet to peppery, depending on the variety. The culinary uses for each vegetable also differ, with kohlrabi being often enjoyed raw in salads or slaws, while cabbage is commonly cooked in dishes such as stir-fries, soups, and stews.
How do the nutritional profiles of kohlrabi and cabbage compare?
Both kohlrabi and cabbage are low-calorie vegetables, rich in vitamins and minerals, but there are some differences in their nutritional content. Kohlrabi is an excellent source of vitamin C, providing more than 100% of the daily recommended intake in a single serving. It is also high in fiber and contains potassium and antioxidants that promote healthy digestion and overall wellness.
Cabbage, while also a good source of vitamin C, is particularly notable for its high levels of vitamin K, which is essential for bone health and blood clotting. Additionally, cabbage contains compounds known as glucosinolates, which may have protective effects against certain types of cancer. Both veggies contribute valuable nutrients to a balanced diet, making them versatile options for various meals.
Can kohlrabi and cabbage be used interchangeably in recipes?
While kohlrabi and cabbage can sometimes be used interchangeably in recipes, they do have unique flavors and textures that can influence the final dish. For example, kohlrabi’s crunchiness and mild sweetness make it a great addition to salads and slaws, offering a different taste compared to the more robust and earthy flavor of cabbage. In cooked dishes, kohlrabi may become tender more quickly than cabbage, which can affect cooking times and textures.
However, when replacing one with the other, it’s important to note the overall flavor profile of the dish. If a recipe calls for cabbage, substituting kohlrabi could result in a sweeter, less pungent dish. Therefore, adjustments in seasoning and cooking methods may be necessary to achieve a similar outcome to the original recipe, allowing the unique qualities of each vegetable to shine.
What are the best ways to prepare kohlrabi and cabbage?
Kohlrabi can be enjoyed in a variety of ways, both raw and cooked. When raw, it can be peeled and sliced into sticks or chips for snacking or grated into salads and slaws for added crunch. Cooking kohlrabi gives it a sweeter flavor and a tender texture, and it can be steamed, sautéed, or roasted. Adding spices and herbs can enhance its natural sweetness, making it a versatile ingredient for both light and hearty meals.
Cabbage is traditionally used in a wide array of dishes such as coleslaw, stir-fries, and soups. It can be finely shredded for salads or chopped into larger pieces for cooked dishes. When sautéed or stir-fried, cabbage develops a sweet, slightly caramelized flavor that complements other ingredients beautifully. Fermentation is another popular preparation method, as seen in sauerkraut or kimchi, where cabbage undergoes a flavorful transformation that contributes probiotics to the diet.
Are there any health benefits specific to kohlrabi and cabbage?
Kohlrabi offers several health benefits due to its rich vitamin and antioxidant content. It is particularly known for its high vitamin C levels, which help boost the immune system and support skin health. Additionally, kohlrabi is rich in fiber, which promotes digestive health and can help regulate blood sugar levels. The antioxidants present in kohlrabi may also play a role in reducing inflammation and protecting against chronic diseases.
Cabbage provides its own set of health benefits, especially its abundance of vitamin K, which is crucial for bone health and proper blood clotting. The presence of glucosinolates in cabbage has been studied for their potential anti-cancer properties, making it a valuable addition to a cancer-preventive diet. Both vegetables are excellent sources of potassium, which aids in blood pressure regulation and heart health, making them beneficial choices for overall well-being.
How can I store kohlrabi and cabbage to maximize their freshness?
To maximize the freshness of kohlrabi, it’s best to store it in the refrigerator. Place unwashed kohlrabi in a perforated plastic bag or wrap it in a damp paper towel and then put it in a plastic bag; this helps maintain humidity and prevents it from drying out. Kohlrabi can typically last in the fridge for several weeks if stored properly, making it an excellent vegetable to have on hand for various recipes.
Cabbage can also be stored in the refrigerator, ideally in the vegetable crisper drawer. To keep it fresh, it should remain uncut until you are ready to use it. Whole cabbage heads can last up to two weeks in the fridge, while cut cabbage should be wrapped tightly in plastic wrap or stored in an airtight container to prevent it from spoiling quickly. Keeping both kohlrabi and cabbage cool and dry is key to enjoying their flavors and health benefits for as long as possible.
