Pale green or purple, with leaves sprouting sporadically from the bulbous stem, kohlrabi looks like something you might find in the depths of the ocean or on another planet. It's not a very popular vegetable, perhaps because of its gnarly appearance, but there's no reason to be afraid if you come across it at the farmers market or in your CSA box. One taste and you just might fall in love. (I know I did.)
Here's what you need to know.
Kohlrabi is a word borrowed from German that is a mash-up of kohl (cabbage) and rübe (turnip). While the flavor reminds me of a turnip - very mild with the ever-so-slightest hint of sweetness - it is not a root vegetable. The bulb is actually the stem of the plant that grows above ground. Instead of a root, it is a cruciferous vegetable, like Brussels sprouts, cabbage and broccoli. (It is often compared to broccoli stems.)
If you're in the market for kohlrabi and they're not foisted upon you in a produce box, you want to stay away from those with blemishes or wilted leaves. (Raw or cooked, the leaves can be eaten too!) Look for smaller bulbs - with a diameter up to 3 inches - as they can become woody when larger. Like cabbage, kohlrabi should be stored in the crisper drawer of the refrigerator where it can last for weeks. If the leaves are attached, you'll want to separate them form the bulb and they should be used within a couple of days.
Before enjoying kohlrabi, be sure to remove the tough, fibrous outer layer with a knife. The smaller, more tender bulbs are most often eaten raw in slaws, salads and as crudité to take advantage of their satisfying crunch. (I found myself munching on them like carrots for a snack.) Save the larger bulbs for cooking - they can be grilled, mashed, roasted, fried, sauteed, etc. - so you can soften the tougher flesh.
Kohlrabi's neutral taste means it's versatile enough to go into just about any savory dish you can think of. But if you're looking for a head start, here are a few recipes that put kohlrabi to good use.
Kohlrabi and Apple Salad
6 to 8 servings.
Kohlrabi tastes sweeter and milder than most cabbages. It assimilates the flavor of whatever is incorporated into the recipe and can be cooked like a potato: boiled, steamed or roasted, mashed, creamed and buttered, but most people have it either raw or slightly sauteed.
Choose small kohlrabi "bulbs" to serve raw; save the large bulbs for recipes in which the vegetable is treated like a potato. Either size should be peeled; the skin can be stringy and tough.
This salad goes well with barbecued ribs and a Belgian white beer.
Make ahead: The salad can be assembled and refrigerated up to 3 days in advance.
• 1/3 c. nonfat plain Greek-style yogurt
• 1/3 c. olive-oil mayonnaise
• Juice of 1 large lemon (2 tbsp.)
• 1 tbsp. coarse-grained mustard
• 1/2 tsp. granulated sugar (optional, especially if the apple is sweet and juicy)
• 2 tbsp. finely chopped flat-leaf parsley leaves, plus a few sprigs for garnish
• 1 1/2 lb. (3 medium) kohlrabi bulbs, peeled, cut crosswise and then cut into very thin strips, julienned
• 2 medium carrots, scrubbed and julienned
• 1 handful (about 10) snow peas (strings discarded), julienned
• 1 medium Granny Smith apple, peeled, cored and julienned
Directions
In a large bowl, whisk together the yogurt, mayonnaise, lemon juice, mustard, sugar, if using, and chopped parsley until combined.
Add the kohlrabi, carrots, snow peas and apple, and mix well to coat evenly. Let sit at room temperature for a few minutes to let all the flavors meld.
Garnish with parsley sprigs and serve.

Black Lentil Salad With Vegetables and Herbs
6 servings
In this salad, matchsticks of kohlrabi or broccoli stems add pale, crisp contrast to tender, caviar-like black lentils, along with juicy grape tomatoes, shallot and herbs, all coated in a rich mustard vinaigrette. It makes a stunning side for a cookout and can also serve as a vegan main course.
The salad can be refrigerated for up to 3 days in an airtight container.
Kohlrabi is most easily found at farmers markets.
The lentils can be cooked and refrigerated in an airtight container for up to 4 days.
• 1 c. (6 1/2 oz.) black beluga lentils
• 3 tbsp. extra-virgin olive oil
• 1 tbsp. fresh lemon juice
• 2 tsp. Dijon mustard
• 1/2 tsp. kosher salt
• 1/2 tsp. freshly ground black pepper
• 2 medium bulbs kohlrabi, tough skins removed, cut into thin matchsticks (about 1 c.)
• 1 c. grape tomatoes, quartered
• 1/4 c. chopped fresh flat-leaf parsley
• 2 tbsp. very finely chopped shallot
• 1 tbsp. chopped fresh tarragon, or 1 tsp. dried tarragon
Directions
Bring 4 cups of water to a boil in a medium pot.
Meanwhile, rinse the lentils and sort through them to remove any stones that may be present. Stir the lentils into the boiling water, reduce the heat to medium-low and simmer until they are just tender, 20 to 25 minutes. Drain and transfer to the refrigerator to cool completely, about 1 hour.
Once the lentils are cool, in a small bowl, whisk together the oil, lemon juice, mustard, salt and pepper.
In a large bowl, combine the lentils with the kohlrabi, tomatoes, parsley, shallot and tarragon. Drizzle the salad with the dressing and toss to combine. Serve at room temperature or chilled.

Fennel and Kohlrabi Salad
6 servings
This crisp, fresh-tasting side dish can be made 2 to 3 hours ahead and refrigerated. Toss again before serving. A mandoline will do the best job of cutting the vegetables paper-thin. The recipe doubles easily.

• 1 bunch scallions, white and light-green parts, cut on the diagonal into 1/2-in. slices
• Juice from 3 large lemons (at least 2/3 c.)
• 1/4 c. canola oil or other neutral oil
• Fine salt
Directions
In a large bowl, toss together the kohlrabi, fennel, scallions, lemon juice and oil until combined. Season to taste with salt and serve right away or chilled.
