Understanding Kohlrabi Leaves

Before diving into cooking techniques, let’s explore what makes kohlrabi leaves worth eating.

Nutritional Powerhouse

Kohlrabi leaves are packed with vitamins and minerals. They are an excellent source of Vitamin C, which boosts your immune system, and Vitamin K, important for blood clotting and bone health. They also contain significant amounts of Vitamin A, fiber, and various antioxidants. Including kohlrabi leaves in your diet is a simple way to boost your nutrient intake.

Taste and Texture

The taste of kohlrabi leaves is often described as similar to kale or collard greens, but milder and slightly sweeter. The texture can be slightly tougher, especially in older leaves, but proper cooking can tenderize them beautifully. Younger leaves are more tender and require less cooking time.

Choosing the Right Leaves

When buying kohlrabi, look for leaves that are vibrant green, firm, and free from blemishes. Avoid leaves that are wilted, yellowed, or have holes. If you’re growing your own kohlrabi, harvest the younger leaves for the best flavor and texture. Freshness is key to enjoying kohlrabi leaves.

Preparing Kohlrabi Leaves for Cooking

Proper preparation is essential for optimal taste and texture.

Washing and Cleaning

Kohlrabi leaves can often be gritty, so thorough washing is crucial. Fill a large bowl with cold water and submerge the leaves. Swish them around to dislodge any dirt or sand. Repeat this process until the water remains clear. You can also use a salad spinner to dry the leaves after washing. Don’t skip this step; nobody wants gritty greens!

Removing Tough Stems

The stems of kohlrabi leaves can be quite tough and fibrous. Use a sharp knife to cut away the stems from the leaves. You can discard the stems, or save them to add to vegetable broth for extra flavor. Removing the stems will improve the overall texture of the cooked leaves.

Chopping or Shredding

Depending on the recipe, you may need to chop or shred the kohlrabi leaves. For sautéing or stir-frying, a rough chop is usually sufficient. For salads, you might prefer to shred the leaves finely. Consider the cooking method when deciding how to cut the leaves.

Cooking Methods for Kohlrabi Leaves

There are many ways to cook kohlrabi leaves, each yielding slightly different results.

Sautéing

Sautéing is a quick and easy way to cook kohlrabi leaves. Heat some olive oil or butter in a large skillet over medium heat. Add minced garlic or shallots for extra flavor. Add the chopped kohlrabi leaves and cook, stirring frequently, until they are wilted and tender, about 5-7 minutes. Season with salt, pepper, and any other desired spices. Sautéing brings out the natural sweetness of the leaves.

Steaming

Steaming is a gentle cooking method that preserves the nutrients in kohlrabi leaves. Place the leaves in a steamer basket over boiling water. Cover and steam for 5-10 minutes, or until they are tender. Season with salt, pepper, and a drizzle of olive oil. Steaming is a healthy way to cook kohlrabi leaves.

Boiling

Boiling is a simple but effective method for cooking kohlrabi leaves, though it can result in some nutrient loss. Bring a pot of salted water to a boil. Add the kohlrabi leaves and cook for 5-10 minutes, or until they are tender. Drain well and season to taste. Boiling is a good option when you want a simple, straightforward dish.

Stir-Frying

Stir-frying is a great way to incorporate kohlrabi leaves into Asian-inspired dishes. Heat some oil in a wok or large skillet over high heat. Add your favorite stir-fry ingredients, such as garlic, ginger, and soy sauce. Add the kohlrabi leaves and stir-fry until they are wilted and tender, about 3-5 minutes. Stir-frying adds a delicious smoky flavor to the leaves.

Adding to Soups and Stews

Kohlrabi leaves can be added to soups and stews for extra flavor and nutrients. Simply chop the leaves and add them to the pot during the last 15-20 minutes of cooking. They will wilt down and add a subtle, earthy flavor to the dish. Kohlrabi leaves are a versatile addition to soups and stews.

Baking and Roasting

You can bake kohlrabi leaves to create crispy greens, similar to kale chips. Toss the leaves with olive oil, salt, and pepper. Spread them in a single layer on a baking sheet and bake at 350°F (175°C) for 10-15 minutes, or until they are crispy. Alternatively, add chopped kohlrabi leaves to a roasting pan with other vegetables for a hearty and nutritious side dish. Baking brings out a different texture from the kohlrabi leaves.

Are kohlrabi leaves edible, and are they as nutritious as the bulb?

Yes, kohlrabi leaves are absolutely edible and often overlooked! Many people are unaware that the leaves offer a delicious and nutritious addition to various dishes. They have a slightly milder and sweeter flavor than the kohlrabi bulb itself, resembling a cross between cabbage and turnip greens, especially when young and tender.

Nutritionally, kohlrabi leaves are packed with vitamins and minerals. They are an excellent source of Vitamin C, Vitamin K, and Vitamin B6, along with essential minerals like calcium, potassium, and magnesium. In some cases, the leaves can actually be more nutritious per serving than the bulb, offering a higher concentration of certain vitamins and antioxidants. This makes them a healthy and flavorful addition to your diet.

How do I choose and store kohlrabi leaves for optimal freshness?

When selecting kohlrabi leaves, look for vibrant green, firm leaves with no signs of wilting, yellowing, or holes. Smaller leaves tend to be more tender and mild in flavor compared to larger, more mature leaves. Avoid leaves that are slimy or have any signs of spoilage, as these won’t taste as good and may not be safe to eat.

To store kohlrabi leaves, remove them from the bulb if they are still attached. Wrap the leaves loosely in a damp paper towel and place them in a perforated plastic bag in the refrigerator. This will help to maintain their moisture and prevent them from wilting. Stored properly, kohlrabi leaves should stay fresh for up to a week, but it’s always best to use them as soon as possible for the best flavor and nutritional value.

What are some popular ways to cook kohlrabi leaves?

Kohlrabi leaves are incredibly versatile and can be prepared in a variety of ways. They can be sautéed, steamed, boiled, or even eaten raw in salads when young and tender. Sautéing them with garlic and olive oil is a simple and delicious way to enjoy their flavor, while steaming preserves more of their nutrients.

Beyond simple cooking methods, kohlrabi leaves can be incorporated into more complex dishes. They can be added to soups, stews, and stir-fries for added flavor and nutrients. Some people even use them to make kohlrabi leaf pesto or add them to smoothies for a nutritional boost. The possibilities are endless, so feel free to experiment and find your favorite ways to use them.

Are there any precautions I should take before eating kohlrabi leaves?

Before consuming kohlrabi leaves, it’s essential to wash them thoroughly to remove any dirt, debris, or insects. A good rinse under cold running water is usually sufficient, but for particularly dirty leaves, you can soak them in a bowl of cold water for a few minutes before rinsing.

While generally safe, some individuals may experience digestive discomfort from eating cruciferous vegetables like kohlrabi leaves, especially if they are not used to consuming them. If you are prone to bloating or gas, it’s best to introduce kohlrabi leaves gradually into your diet and cook them thoroughly to make them easier to digest. Additionally, individuals on blood-thinning medication should monitor their Vitamin K intake, as kohlrabi leaves are a good source of this vitamin.

Can I freeze kohlrabi leaves for later use?

Yes, you can freeze kohlrabi leaves to preserve them for later use, although the texture may change slightly after thawing. Blanching the leaves before freezing helps to preserve their color, flavor, and nutrients. To blanch, submerge the cleaned kohlrabi leaves in boiling water for 2-3 minutes, then immediately transfer them to an ice bath to stop the cooking process.

Once the blanched leaves have cooled, drain them thoroughly and squeeze out any excess water. Spread the leaves in a single layer on a baking sheet and freeze until solid. Then, transfer the frozen leaves to a freezer-safe bag or container, removing as much air as possible. Frozen kohlrabi leaves can be stored in the freezer for up to 6-8 months and are best used in cooked dishes like soups, stews, or stir-fries.

How do kohlrabi leaves compare to other leafy greens in terms of taste?

Kohlrabi leaves offer a unique flavor profile compared to other popular leafy greens. While they share some similarities with cabbage and turnip greens, kohlrabi leaves generally have a milder and slightly sweeter taste. The flavor can also vary depending on the maturity of the leaves, with younger leaves being more tender and less pungent.

Compared to spinach, kohlrabi leaves have a firmer texture and a more pronounced flavor. They are less bitter than kale and more subtle than mustard greens. Their mildness makes them a good choice for those who find other leafy greens too strong or bitter. This versatile flavor allows them to complement a wide range of dishes without overpowering other ingredients.

Are there any kohlrabi varieties where the leaves are particularly prized?

While all kohlrabi varieties have edible leaves, some varieties are known for having particularly tender and flavorful foliage. The ‘White Vienna’ and ‘Purple Vienna’ varieties are commonly grown, and their leaves are generally well-regarded. However, the quality of the leaves often depends more on growing conditions and the age of the plant than the specific variety.

Generally, smaller and younger kohlrabi plants will have more tender and palatable leaves. Regardless of the variety, it’s best to harvest the leaves when they are relatively small and still vibrant green. Focusing on proper growing techniques, such as providing adequate water and sunlight, will also contribute to the overall quality and flavor of the leaves.
