Introduction
Move over, potatoes and carrots! There’s a new duo of root vegetables vying for the spotlight in kitchens around the world. Rutabaga and kohlrabi, once relegated to the corners of farmers’ markets, are now emerging as culinary darlings. These humble veggies pack a punch of flavor and nutrition that’s turning heads and tantalizing taste buds.
But what sets these two apart? Are they interchangeable, or does each bring something unique to the table? Let’s dig in and unearth the secrets of rutabaga and kohlrabi, from their quirky appearances to their versatile uses in the kitchen.
What are Rutabaga and Kohlrabi
Rutabaga Basics and Varieties
Rutabaga, the gentle giant of root vegetables, is a cross between cabbage and turnip. This hardy crop thrives in cooler climates, producing large, round roots with a distinctive purple-tinged top and creamy bottom. Most rutabagas you’ll encounter are of the American Purple Top variety, but adventurous gardeners might stumble upon the Laurentian or Joan varieties.
These hefty veggies can grow up to 6 inches in diameter, though smaller ones tend to be sweeter. Their flesh ranges from pale yellow to deep orange, hinting at the earthy sweetness within.
Kohlrabi Basics and Varieties
Kohlrabi, on the other hand, is the alien spaceship of the vegetable world. Its name means “cabbage turnip” in German, but don’t let that fool you – this veggie is in a league of its own. With a bulbous base and leaf-topped stems jutting out at odd angles, kohlrabi looks like it could take flight at any moment.
You’ll find two main types: purple and green. Popular varieties include the quick-growing Early White Vienna and the vibrant Purple Danube. Despite its otherworldly appearance, kohlrabi is surprisingly versatile and easy to grow.
Names and Family Ties
Both rutabaga and kohlrabi belong to the Brassica family, rubbing shoulders with broccoli, cabbage, and kale. Rutabaga goes by many names – swede in the UK, neep in Scotland, and snagger in the American South. Kohlrabi keeps things simpler, sometimes called German turnip or stem turnip.
These cousins share a cabbage-like heritage, but their paths diverged long ago. Rutabaga emerged in Scandinavia in the 17th century, while kohlrabi traces its roots back to ancient Roman times.
Appearance and Texture
Rutabaga Look and Feel
Picture a rutabaga as nature’s bowling ball – round, hefty, and ready to roll. Its skin is typically waxed to preserve freshness, giving it a slightly waxy feel. Beneath that protective layer lies a dense, creamy flesh that’s firm to the touch.
Cut into a rutabaga, and you’ll reveal concentric rings of pale yellow to orange flesh. Its texture is somewhere between a potato and a turnip – starchy yet slightly watery, with a satisfying crunch when raw.
Kohlrabi Look and Feel
Kohlrabi, in contrast, looks like it stepped out of a sci-fi novel. Its bulbous base can be green or purple, with a network of leaf stems sprouting from the top. Peel away the tough outer skin, and you’ll find a crisp, juicy interior that’s almost apple-like in texture.
The flesh of kohlrabi is typically white or pale green, regardless of its exterior color. It’s crunchy and refreshing when raw, with a texture that softens beautifully when cooked.
Flavor Profiles
Rutabaga Taste
Rutabaga brings a complex flavor to the table. Raw, it offers a crisp, slightly peppery bite reminiscent of a mild radish. Cook it, and the magic happens – the flesh becomes tender and sweet, with earthy undertones that hint at its turnip heritage.
There’s a subtle bitterness that adds depth to rutabaga’s flavor profile. This unique taste makes it a chameleon in the kitchen, equally at home in savory stews or mashed with a touch of butter and cream.
Kohlrabi Taste
Kohlrabi is the surprise artist of the vegetable world. Its flavor is unexpectedly mild and sweet, with a refreshing crispness that’s hard to pin down. Some liken it to a broccoli stem, while others detect notes of radish or cucumber.
Raw kohlrabi has a clean, slightly peppery taste that shines in salads. Cooking mellows its flavor, bringing out a subtle sweetness that pairs beautifully with herbs and spices.
Culinary Uses
Cooking with Rutabaga
Rutabaga is a culinary chameleon, adapting to a wide range of cooking methods. Roasting brings out its natural sweetness, while mashing creates a comforting side dish that rivals potatoes. Brave cooks might even try their hand at rutabaga fries – a healthier alternative to the classic spud version.
In soups and stews, rutabaga adds body and a subtle earthy flavor. Grate it raw into slaws for a peppery crunch, or slice it thin for a unique take on gratin. Don’t shy away from experimenting – rutabaga can handle bold flavors and spices with aplomb.
Cooking with Kohlrabi
Kohlrabi’s versatility is its secret weapon. Raw, it’s a crunchy addition to salads or crudité platters. Slice it thin and quick-pickle it for a tangy condiment that brightens up sandwiches and tacos.
Cooked, kohlrabi takes on a tender, almost creamy texture. Sauté it with garlic and herbs for a simple side dish, or puree it into a silky soup. The leaves are edible too – treat them like kale or collard greens for an extra nutritional boost.
Modern Trends and Diets
Both rutabaga and kohlrabi are finding their place in modern, health-conscious kitchens. Low-carb dieters love rutabaga as a potato substitute, while kohlrabi’s crisp texture makes it perfect for veggie noodles and rice alternatives.
Plant-based eaters appreciate the meaty texture of roasted rutabaga in vegetarian dishes. Kohlrabi, with its mild flavor, easily absorbs marinades and spices, making it a favorite in vegan stir-fries and curries.
Nutritional Value and Health Benefits
When it comes to nutrition, both rutabaga and kohlrabi punch above their weight. Here’s a quick comparison:
| Nutrient (per 100g) | Rutabaga | Kohlrabi |
|---|---|---|
| Calories | 37 | 27 |
| Carbohydrates | 8.6g | 6.2g |
| Fiber | 2.3g | 3.6g |

Rutabaga shines with its high vitamin C content and impressive array of antioxidants. It’s also a good source of potassium and manganese, supporting heart health and bone strength.
Kohlrabi, not to be outdone, boasts even more vitamin C than rutabaga. It’s also rich in B vitamins and provides a hefty dose of fiber, promoting digestive health and satiety.
Both vegetables are low in calories and high in nutrients, making them excellent choices for weight management and overall health. Their fiber content supports gut health, while their antioxidants may help reduce inflammation and boost immune function.
Cultivation and Seasonality
Growing Rutabaga
Rutabagas thrive in cool weather, making them ideal for fall harvests. Plant seeds directly in the garden about 3 months before the first expected frost. They prefer well-drained soil rich in organic matter and full sun exposure.
These hardy plants are relatively low-maintenance, but consistent moisture is key to developing sweet, tender roots. Harvest when the roots reach 3-5 inches in diameter, usually after the first light frost has sweetened their flavor.
Growing Kohlrabi
Kohlrabi is a quick-growing crop that can be planted in spring for early summer harvest or in late summer for fall crops. It’s less fussy about soil than rutabaga but still appreciates well-drained, fertile ground.
Keep an eye on your kohlrabi – it’s ready to harvest when the bulb reaches 2-3 inches in diameter. Letting it grow too large can result in woody, tough vegetables. With successive plantings, you can enjoy fresh kohlrabi from spring through fall.
Selecting and Storing
Choosing the Best Rutabaga
At the market, look for rutabagas that feel heavy for their size, with smooth, firm skin. Smaller ones (about 4 inches in diameter) tend to be sweeter and more tender. Avoid any with soft spots or blemishes.
Don’t be put off by the waxy coating – it’s there to prevent moisture loss. Store rutabagas in a cool, dark place or in the refrigerator’s crisper drawer. They’ll keep for several weeks, sometimes even months, making them a great staple to have on hand.
Picking Perfect Kohlrabi
When selecting kohlrabi, size matters. Aim for bulbs 2-4 inches in diameter – any larger and they might be tough or woody. The skin should be unblemished, and any attached leaves should look fresh and crisp.
Store kohlrabi in the refrigerator, where it will keep for several weeks. If the leaves are attached, use them within a few days – they’re delicious and nutritious but wilt quickly.
Historical and Cultural Significance
Rutabaga and kohlrabi may seem like newcomers to many tables, but they’ve been quietly shaping culinary traditions for centuries. Rutabaga, born in the cold climates of Scandinavia, became a staple during times of famine due to its hardiness and long storage life. In Scotland, “neeps and tatties” (mashed rutabaga and potatoes) is a classic accompaniment to haggis on Burns Night.
Kohlrabi, with its longer history, has found its way into diverse cuisines. In Kashmir, it stars in a traditional dish called “monji-haak,” while German cooks have long appreciated its versatility in soups and stews. In recent years, both vegetables have been rediscovered by chefs and home cooks alike, sparking a renaissance in root vegetable cookery.
Conclusion
Rutabaga and kohlrabi, once overlooked, are now stepping into the limelight. Each brings its own unique charm to the table – rutabaga with its earthy sweetness and hearty texture, kohlrabi with its crisp refreshment and subtle flavor. As we’ve uncovered their secrets, from field to fork, it’s clear that both deserve a place in our culinary repertoire.
So next time you’re at the market, grab a rutabaga in one hand and a kohlrabi in the other. Your kitchen adventures – and your taste buds – will be all the richer for it.
