Kohlrabi, sometimes called a German turnip or a stem turnip, is a vegetable that might look a little alien to the uninitiated. Its bulbous shape and sprouting leaves can be intimidating, but beneath that exterior lies a subtly flavored, versatile ingredient. If you’re curious about exploring this unusual vegetable, understanding its flavor profile, especially when boiled, is key. So, what does boiled kohlrabi taste like? Let’s uncover the nuances of its taste and texture.
Understanding Kohlrabi: A Botanical Overview
Before diving into the flavor, let’s understand what kohlrabi actually is. Kohlrabi (Brassica oleracea Gongylodes Group) is a member of the Brassica family, which also includes cabbage, broccoli, cauliflower, and kale. This family is known for its nutritional density and diverse flavors.
Kohlrabi is unique because it’s the swollen stem of the plant that is primarily eaten. The bulb grows above ground and can range in color from pale green to purple. Both the bulb and the leaves are edible, offering slightly different flavors and textures.
The name “kohlrabi” itself is German, combining “kohl” (cabbage) and “rabi” (turnip), hinting at its flavor characteristics.
The Flavor Profile of Raw Kohlrabi
To better understand the taste of boiled kohlrabi, it’s helpful to first consider its raw flavor. Raw kohlrabi has a mild, slightly sweet, and subtly peppery taste. Many describe it as a cross between a turnip and a cabbage, with a hint of broccoli stem.
The texture of raw kohlrabi is crisp and juicy, similar to an apple or a radish. It’s this crispness that makes it a refreshing addition to salads and slaws. Young, smaller kohlrabi bulbs tend to be sweeter and more tender than larger, more mature ones. As the kohlrabi matures, it can develop a slightly tougher texture and a more pronounced, sometimes slightly bitter, flavor.
The leaves of the kohlrabi plant, when young and tender, can be eaten raw as well. They have a slightly stronger, more assertive flavor than the bulb, similar to kale or collard greens.
Boiling Kohlrabi: How Cooking Affects the Flavor
Boiling is a simple and common method for preparing kohlrabi. However, the cooking process significantly alters both the texture and the flavor of the vegetable. So, what changes when you boil kohlrabi?
The Impact on Texture
Boiling softens the crisp texture of raw kohlrabi. The longer it’s boiled, the softer it becomes. Overcooked kohlrabi can become mushy and unappetizing. The ideal texture for boiled kohlrabi is tender-crisp, meaning it’s cooked through but still retains a slight bite.
The Transformation of Flavor
Boiling mellows out the raw kohlrabi’s flavor. The peppery notes diminish, and the sweetness becomes more pronounced. The overall flavor becomes milder and more subtle. Some might describe the taste of boiled kohlrabi as slightly bland if it’s not seasoned properly.
The water-soluble compounds responsible for some of the more pungent or peppery flavors leach out into the boiling water, leaving behind a milder, sweeter taste. This is why proper seasoning is crucial to enhance the flavor of boiled kohlrabi.
What Does Boiled Kohlrabi Actually Taste Like? Deconstructing the Flavor
Describing the taste of boiled kohlrabi isn’t straightforward, as it’s a nuanced and subtle flavor. However, here’s a breakdown of the key characteristics:
- Mildly Sweet: The sweetness present in raw kohlrabi is accentuated by boiling. It’s a gentle sweetness, not overpowering like a carrot or a beet.
- Subtly Cabbage-Like: The Brassica family resemblance is still evident, but the cabbage flavor is significantly muted compared to raw cabbage.
- Slightly Turnip-Like: There’s a hint of turnip flavor, but it’s less earthy and pungent than a true turnip.
- Delicate and Clean: Boiled kohlrabi has a clean and refreshing taste, making it a versatile ingredient that can complement a wide range of flavors.
- Absorbs Flavors Well: Boiled kohlrabi readily absorbs the flavors of the cooking water and any seasonings added. This makes it a blank canvas for creating flavorful dishes.
In essence, boiled kohlrabi tastes like a gentle, slightly sweet version of its raw self. It’s a blank canvas that benefits from thoughtful seasoning and complementary ingredients.
Factors Affecting the Taste of Boiled Kohlrabi
Several factors can influence the taste of boiled kohlrabi:
- Size and Maturity: Younger, smaller kohlrabi bulbs tend to be sweeter and more tender. Larger, more mature bulbs may have a slightly tougher texture and a more pronounced flavor.
- Cooking Time: Overcooking kohlrabi will result in a mushy texture and a bland flavor. Undercooked kohlrabi will be too firm. Aim for a tender-crisp texture.
- Water Quality: The quality of the water used for boiling can affect the taste. Filtered water is generally preferable to tap water.
- Seasoning: The seasonings added to the boiling water or after cooking will significantly impact the flavor of the kohlrabi. Salt, pepper, herbs, and spices can all be used to enhance its taste.
- Variety: While not as diverse as other vegetables, some kohlrabi varieties have slightly different flavor profiles. Green varieties tend to be milder than purple varieties.
Tips for Cooking Kohlrabi to Perfection
To ensure your boiled kohlrabi tastes its best, follow these tips:
- Choose Young, Firm Bulbs: Select kohlrabi bulbs that are small to medium in size and feel firm to the touch. Avoid bulbs that are soft, bruised, or cracked.
- Peel Thoroughly: Use a sharp knife or vegetable peeler to remove the tough outer skin. The skin can be fibrous and bitter.
- Cut into Uniform Pieces: Cut the kohlrabi into uniform pieces to ensure even cooking. Cubes or wedges are good options.
- Boil in Salted Water: Add salt to the boiling water. Salt helps to season the kohlrabi from the inside out and enhances its natural sweetness.
- Don’t Overcook: Boil until tender-crisp. This usually takes about 10-15 minutes, depending on the size of the pieces. Test for doneness by piercing with a fork.
- Drain Well: Drain the kohlrabi thoroughly after boiling to remove excess water.
- Season Generously: Season the boiled kohlrabi with salt, pepper, and other seasonings to taste. Consider adding butter, olive oil, herbs, or spices.

What is kohlrabi and where does it originate?
Kohlrabi, also known as German turnip, is a member of the Brassica family, related to cabbage, broccoli, and cauliflower. It’s characterized by its bulbous stem and leafy greens that can also be consumed. This interesting vegetable offers a unique flavor and texture, making it a versatile ingredient in various cuisines.
Kohlrabi’s origins trace back to Europe, specifically the region surrounding the Mediterranean Sea. It gradually spread throughout the continent and eventually made its way to other parts of the world. Today, it’s cultivated in many countries and enjoyed for its distinct culinary qualities.
How would you describe the general taste of kohlrabi, both raw and cooked?
Raw kohlrabi offers a crisp, refreshing taste that resembles a mild radish or turnip. It’s slightly sweet with a subtle peppery note, making it a pleasant and crunchy addition to salads or crudités platters. The texture is similar to a water chestnut, providing a satisfying snap.
Cooking kohlrabi mellows its flavor, bringing out its sweetness and reducing any peppery sharpness. The taste becomes more akin to a sweeter cabbage or a mild turnip. The texture softens considerably, becoming tender and slightly creamy, making it ideal for soups, stews, and stir-fries.
What does boiled kohlrabi taste like specifically, compared to other cooking methods?
Boiled kohlrabi develops a noticeably sweeter and milder flavor compared to when it’s raw. The boiling process softens the fibers, creating a tender and slightly watery texture. The taste profile is often compared to a sweeter, less assertive turnip or a mild cabbage.
Compared to roasting or grilling, boiling results in a less concentrated flavor as some of the natural sugars and compounds leach into the cooking water. However, boiling allows the kohlrabi to become very tender, making it suitable for pureeing or incorporating into creamy soups and sauces. It loses some of its characteristic crispness in favor of a more yielding texture.
What factors can influence the taste of boiled kohlrabi?
The size and age of the kohlrabi bulb significantly impact its flavor when boiled. Smaller, younger kohlrabi bulbs tend to be sweeter and more tender, resulting in a more pleasant and less bitter taste after boiling. Larger, older bulbs can develop a tougher texture and a more pronounced, sometimes slightly bitter, flavor.
The cooking time also plays a crucial role. Overboiling kohlrabi can lead to a mushy texture and a bland, watery taste. Underboiling, on the other hand, may result in a tougher texture and a slightly sharper flavor. Achieving the right balance is essential for optimal taste and texture.
What are some recommended seasonings or accompaniments to enhance the taste of boiled kohlrabi?
Boiled kohlrabi’s mild flavor makes it a versatile canvas for various seasonings. Simple additions like salt, pepper, and a knob of butter can enhance its natural sweetness and create a satisfying side dish. Fresh herbs like parsley, chives, or dill complement its subtle flavor profile perfectly.
For a more complex flavor profile, consider adding spices like nutmeg, cumin, or coriander. A squeeze of lemon juice or a splash of vinegar can brighten the taste and add a touch of acidity. Boiled kohlrabi also pairs well with creamy sauces, such as a béchamel or a cheese sauce, adding richness and depth.
Are there any specific varieties of kohlrabi that taste different when boiled?
Yes, while the general taste profile of boiled kohlrabi remains consistent, subtle differences exist between varieties. The most common varieties are green and purple kohlrabi, with the primary difference being their outer skin color. The flesh inside is typically pale green regardless of the skin color.
Some believe that purple kohlrabi has a slightly sweeter and milder flavor than green kohlrabi when boiled, but this difference is often negligible. The age and growing conditions of the kohlrabi have a far greater impact on its flavor than the variety itself. Locally grown and freshly harvested kohlrabi, regardless of variety, will generally taste better.
Can you suggest a simple boiled kohlrabi recipe?
Start by peeling the kohlrabi bulb and cutting it into evenly sized cubes, about 1-inch in size. Place the kohlrabi cubes in a saucepan and cover with cold water. Add a pinch of salt to the water.
Bring the water to a boil, then reduce the heat and simmer for about 10-15 minutes, or until the kohlrabi is tender when pierced with a fork. Drain the water and toss the boiled kohlrabi with butter, salt, pepper, and your favorite fresh herbs, such as parsley or dill. Serve warm as a simple and flavorful side dish.
