It belongs to the Brassica family, which includes cabbage, broccoli, and cauliflower, and is often described as a cross between a cabbage and a turnip. One of the most common questions people have when they encounter kohlrabi for the first time is whether they should eat the skin or not. In this article, we will delve into the world of kohlrabi, exploring its nutritional value, culinary uses, and most importantly, the edibility of its skin.
Introduction to Kohlrabi
Kohlrabi is a cool-season crop that thrives in temperate climates. It is characterized by its bulbous stem, which can be green, purple, or white, depending on the variety. The leaves are edible and can be used in salads or as a cooking green. Kohlrabi’s flavor profile is often described as sweet and slightly peppery, making it a versatile ingredient in many dishes.
Nutritional Benefits of Kohlrabi
Kohlrabi is rich in vitamins and minerals, making it a nutritious addition to a balanced diet. It is high in vitamin C, which boosts the immune system, and potassium, which helps lower blood pressure. Additionally, kohlrabi contains a significant amount of fiber, aiding in digestion and promoting satiety. The leaves are also a good source of calcium and iron, essential for bone health and preventing anemia.
Culinary Uses of Kohlrabi
The versatility of kohlrabi makes it a favorite among chefs and home cooks alike. It can be eaten raw in salads, roasted as a side dish, or used in soups and stews. The bulb can be sliced thinly and added to sandwiches for a crunchy texture and sweet flavor. Kohlrabi can also be fermented, similar to sauerkraut, to create a healthy and tangy condiment.
The Skin of Kohlrabi: Edible or Not?
The skin of kohlrabi, depending on the variety and how it is cooked, can be either tender and delicious or tough and fibrous. Generally, younger kohlrabi tends to have thinner, more edible skin, while older kohlrabi may require peeling due to its thicker, woodier skin. The decision to eat the skin or not also depends on personal preference and the method of preparation. For instance, if you are roasting kohlrabi, the skin can add a nice texture and help retain moisture. However, in salads or when eating it raw, peeling might be preferable for a smoother experience.
Preparing Kohlrabi Skin for Consumption
If you decide to eat the skin, there are a few tips to make it more palatable. First, choose fresh kohlrabi with no signs of wilting or soft spots. Second, wash the kohlrabi thoroughly under running water to remove any dirt or pesticide residues. For tougher skin, light scrubbing with a vegetable brush can help remove any stubborn dirt and slightly soften the skin.
Benefits of Eating Kohlrabi Skin
Eating the skin of kohlrabi can provide additional fiber and nutrients that might be lost during peeling. The skin is also rich in antioxidants, which help protect the body against free radicals and oxidative stress. Furthermore, consuming the skin can reduce food waste, making your meal more sustainable and economically friendly.

Kohlrabi can be prepared in numerous ways to bring out its unique flavor and texture. Here are some popular cooking methods:
- Roasting: Cut kohlrabi into wedges or cubes, toss with olive oil, salt, and your choice of herbs, and roast in the oven at 425°F (220°C) for about 20-25 minutes, or until tender and lightly browned.
- Sautéing: Slice kohlrabi thinly and sauté in a pan with some butter or oil until it reaches your desired level of crispiness. This method is great for bringing out the natural sweetness of kohlrabi.
