Origin & Classification

First of all, what’s the deal with the interesting name?

Because no other countries consume as much of this vegetable as the Germans do, its local name has been adopted internationally. English, Japanese, and Russian speaking people also know it by this distinct name.

In the original German, “kohl” means cabbage, and “rabi” (a Swiss German variant of rübe) means turnip. Put them together, and what do you get? Kohlrabi, or “turnip cabbage.”

Besides Germany, where the vegetable first gained popularity, Austria, Switzerland, Italy, Spain, Vietnam, and the United States are all producers of this special brassica. According to Matt Duckor at Epicurious, the vegetable first appeared in Italy, where drawings of it in herbal books have been found as far back as the 16th century.

The bulb (more like an enlarged tuberous stem, really) grows aboveground and can reach a size of up to 8 inches (20 centimeters) in diameter, however, its texture is best if harvested when it is between 2 and 4 inches around. The bulb becomes tough and woody in texture as it grows.

Its shape is a round, squat bulb, similar to a turnip. Leaves grow on top, and stems extend from the middle of the bulb like long, thin arms.

The color varies in most cases from off-white to pale green, although purple varieties exist, too. In both cases, the inside flesh has a creamy beige color with a subtly nutty and delicately sweet flavor, similar to that of a turnip or broccoli, and less cabbage-like than its relatives the cauliflower and savoy cabbage.

According to the University of California Berkeley Wellness blog, the vegetable contains lots of vitamins and minerals, include high amounts of vitamins C, B6, and E as well as potassium. It’s also a good source of glucosinolates (like other members of the cabbage family) which may improve antioxidant functions of the body.

Its flavor makes kohlrabi a perfect vegetable to combine with several types of spices and other vegetables, and it can be prepared in a variety of ways.

Choosing the Best

The best way to detect the freshness of the veggie in the grocery store or at the farmers market is to have a close look at its surface.

It should feel firm, and have smooth skin without any spots or cracks. If the leaves are still on, they should look fresh and crunchy.

It can be difficult to avoid choosing specimens with that unwanted woody flavor based on appearance alone. But in general, smaller kohlrabi tend to taste less woody than bigger ones.

How to Store Properly

There are some details you should know in order to keep kohlrabi fresh at home.

The best way to store this vegetable is to remove any leaves (and reserve them for later – they are quite tasty as well) and keep the bulb in the fridge, wrapped in a moist kitchen towel or in a plastic bag in the vegetable drawer. This will keep your kohlrabi crunchy for about a week.

Kohlrabi in a Colander | Foodal.com
A colander with a stand base can come in handy for washing fresh produce like kohlrabi.

Once you cut it, if you do not wish to consume the whole vegetable at once, you can wrap the cut surface with plastic wrap so it doesn’t dry out. If you cut the vegetable into smaller pieces, they can be stored in an airtight container or plastic bag. Consume cut kohlrabi within a few days.

Freezing is also an option, if you’d like to be able to store kohlrabi for longer periods.

Peel and cut the flesh into chunks or slices, and blanch the pieces for about three minutes in boiling water. Transfer from the boiling water to an ice water bath to stop the cooking, then strain, blot dry, and store in an airtight container before putting it into the freezer. This is especially helpful to prevent a change in texture and color when thawing and cooking again.

When it comes to the leaves, they have a much shorter shelf life. These will only stay fresh for a few days.

Wait to wash the leaves until right before you are ready to consume them, or they will rot quickly. Store in the refrigerator in a plastic bag, wrapped in paper towels if they are damp when you bring them home.

Preparation Tips

If possible, it’s a great idea to use the leaves because they contain lots of nutrients, even more than the bulbs.

The flavor of the leaves has been compared to kale or collard greens. Why not roughly chop and add them to a salad, or blanch or sauté them for a few minutes to serve as a side?

However you are going to process the bulb, always make sure to remove the stalks and any rough edges around the base first. They will taste woody with a hard texture, and therefore aren’t suited for consumption.

After that, peel the skin with a small knife or a vegetable peeler and cut into chunks, slices, or strips – whatever you prefer or that your recipe requires.

Another great advantage of this vegetable is that is can be consumed raw. Shredded or finely chopped, kohlrabi makes a great addition to raw salads and also works as a healthy snack. Its raw flavor is similar to a sweet turnip with a texture like an apple.

Sliced, chopped, or shredded, kohlrabi can add flavor and crunch to a variety of dishes. Learn more: http://foodal.com/knowledge/paleo/kohlrabi-storing-using/
Shredded kohlrabi makes a tasty addition to a variety of dishes, like salads and vegetable fritters.

In general, the cooking time for a whole bulb is 20 to 30 minutes, depending on the size. Chopped, the cook time decreases to 15 to 20 minutes. Steam the vegetable rather than boiling, to preserve the nutrients.

The test cooks over at The Kitchn also recommend roasting it, as it caramelizes in the high heat.

It’s delicious in combination with other root vegetables, especially in a root veggie roast, as recommended above; and it’s also great when blended to make our recipe for creamy vegan kohlrabi soup

Kohlrabi also makes an excellent pickle, or it can be shredded and made into fritters or a raw slaw with a vinagrette or mayonnaise dressing.

Flavor Combinations

If you’re a fan of creative cooking, there is no better friend to have than kohlrabi. This member of the brassica family goes well with numerous spices and herbs. In fact, I haven’t come across a flavor combination that I didn’t enjoy. It is the perfect base to test a wide variety of flavor combinations.

Some of my favorite flavor combinations include caraway, curry, nutmeg, tarragon, and thyme.

According to Karen Page and Andrew Dornenburg’s bestselling book The Flavor Bible, available on Amazon, some additional herbs and spices that pair well with this veggie are:

It also pairs nicely with the pungent herb ramson, similar to North American ramps.

Try it with other vegetables too, like cabbage, carrots, celery, leeks, onions, and potatoes.

Cooking Ideas

Provided that you can find a few medium-sized kohlrabi, I have three wonderful ideas for you to try out at home:

1. Fill It

Did you enjoy my recipe for stuffed onions? This recipe is just as delicious when it’s made with kohlrabi instead.

Boil the bulbs whole in vegetable or chicken stock (with stems, leaves, and any tough ends removed), then let them cool. Remove the tops, and hollow them out.

Just as you did with the onions, this hollowed out portion can be added to the stuffing. The remaining directions and suggestions for the recipe stay the same.

2. Spiralize It

For a refreshing raw salad with a spicy sauce packed with flavorful ingredients like rice vinegar, ginger, soy sauce, and lots of pepper flakes, give my recipe for spicy spiralized kohlrabi slaw a try.

3. Fry It

Make some vegetarian cutlets! For this dish, cook the bulb whole until it is al dente – you don’t want it to become too soft.

Leave to cool, and then slice lengthwise into 1-inch-thick pieces. Toss in beaten eggs and breadcrumbs, and fry in a pan with butter or olive oil until golden brown on both sides.

Tip: For a more crunchy texture, do not cook the kohlrabi before breading and frying it. The centers will remain crisp, with a fresh, sweet flavor.

10 thoughts on “Kohlrabi: Storing and Using This Versatile Vegetable

  1. Well, to my knowledge, I’ve never eaten kohlrabi, However, I love cabbage and I was excited to find this and taste some! Alas, I went to the farmer’s market and to the grocery store in town that has the largest selection of produce. Both did not carry kohlrabi. So, I am going to have to figure out where I can get it locally.

    • What a pity that you couldn’t find some on the farmer’s market as well. I really hope for you to find some other place, because if you’re a cabbage-fan, this one is definitely worth to try. I’m sure you would like it and the different ways you can combine and prepare it.

  2. No, I’ve never cooked with it and I don’t believe, I’ve ever eaten it. It’s time to start preparing for the fall garden and my dad gave me some seeds not to long ago, this article has given me the push to plant a few.

    • Oh that’s great! I haven’t planted some on my own, because I haven’t got the space, but I’ll keep my fingers crossed that those seeds will provide you with some wonderful and fleshy kohlrabi once they’re ready. 🙂 Good luck!

  3. Can’t say I’ve ever eaten that either, but I’m looking forward to one day if I ever find it. I’ve never seen this type of vegetable at our farmers market which leads me to believe that they don’t stock it. How unfortunate, it would have been very nice to experiment with a new flavor.

    • You’re right, I also enjoy trying out new products. I hope that some farmers might have just hidden them 😉 , and you’ll be able to buy them some time, good luck!

  4. What an unusual vegetable. I have never seen this in England! I think I’d like to try it, though, as your description of the flavour sounds very interesting. Thanks for sharing this.

    • I would have thought it would be available in England, too. But maybe you’re still lucky to find some around. It is really a great veggie to try, because it’s so versatile. When you’ve got the chance to get some, you should go ahead 🙂

  5. We had a roasted kohlrabi for dinner tonight! It was delicious – a great substitute for potatoes. I peeled and cut it into chunks, tossed it with olive oil, salt, pepper, and some herbs, placed it in a glass baking dish and roasted for 40 minutes on 400 degrees. At the last 10 minutes I tossed in some leftover brats cut up. I ate it with sour cream and my husband used ketchup. I think parmesan cheese would have been good too. It was really delicious and filling. Thanks for your additional ideas!
