Celery root, also known as celeriac, is an unassuming vegetable, to be sure. Lacking the bright colors of carrots or the intriguing shapes of potatoes, it is often overlooked among more eye-catching produce options. However, behind its rough and knobby exterior lies a world of culinary potential and nutritional benefits that should not be ignored. Read on to discover the incredible versatility, rich flavor, and health perks this humble root has to offer.
What is Celery Root?
Perhaps the biggest barrier to celery root achieving wider popularity is simply its obscurity. Many consumers have never heard of it, let alone tasted it. So what exactly is celeriac?
Celery root is a variety of celery grown specifically for its edible hypocotyl and taproot rather than its stalks and leaves. While it lacks the familiar stringy stems of common celery, it boasts a more intensely concentrated, aromatic celery flavor. In fact, the entire plant contains the same phthalides that give celery its signature taste and smell. The root itself has a crisp, starchy, savory quality with tangy and nutty notes similar to parsley root, but cleaner and fresher tasting overall.
Despite its moniker, celeriac is not actually the swollen root of traditional celery. Instead, it derives from a special celery cultivar (Apium graveolens var. rapaceum) bred solely for its bulbous base rather than ribbed stalks. Over time, celeriac was further developed to minimize foliage and long stems in order to channel the plant’s energy towards enlarging its hypocotyl and taproot.
Other common names for celeriac include turnip-rooted celery, knob celery, and celery knob. Europe and North Africa boast the longest history using it as a food crop. However, it has become increasingly exported to other regions where it continues gaining traction for its versatility in various cuisines.
Identifying Celery Root
When shopping for celeriac, keep your eye out for large, heavy, firm spheres ranging from baseball to softball size with brown papery skin and an inner white flesh. Older, overgrown roots tend to get hollow and pithy around the center, making them less ideal, so select specimens that feel dense all the way through. The taproot and lower portion of the hypocotyl are the most tender and flavorful sections to consume.
Celeriac roots grow just below soil level, where small feeding roots surround the surface. Avoid specimens with numerous bulbous protrusions, cracks, mold, or black spots. The skin and all traces of dirt must be peeled, but roots in peak freshness should exhibit a smooth, mostly spherical shape underneath with a creamy white interior maintaining faint hints of greenish-yellow or light gray.
Nutrition and Benefits
Don’t let its starchy composition fool you – celeriac packs some serious nutritional value. In just one raw cup:

As a low-carb, nutrient-dense whole food, celery root offers antioxidants and phytochemicals that control inflammation and protect cells. Its high fiber content supports digestive health and heart health by regulating cholesterol. The vitamins and minerals celeriac provides even further reduce cardiovascular disease risk while promoting proper muscle, nerve, and metabolic functionality.
The inclusion of certain flavonoid antioxidants could help combat cancer by eliminating free radicals within the body. Some early research indicates the phthalides unique to celery may also lower blood pressure, though more studies are still needed. Nonetheless, adding celery root to one’s diet constitutes an easy way to incorporate beneficial nutrition into meals.
Purchasing and Storage
Celeriac has an exceptionally long storage life compared to most other fresh produce items. Kept dry, clean, and cold, whole roots can last over six months. Avoid washing them until ready to use, as excess moisture quickens deterioration. Simply trim off stalks and rootlets first with a knife, brush off any remaining dirt clumps (no need to fully peel yet), then place uncut roots in a perforated plastic bag inside the crisper drawer of your refrigerator.
Properly stored celery root will keep fresh for at least one to three months when left intact. Once peeled and sliced, it holds for about five days when refrigerated in an airtight container fully submerged in water to prevent oxidation. Freezing cut pieces for future usage is another excellent preservation method, allowing celeriac to retain its texture better than many other frozen produce options.
Where to Find Celery Root
Due to its long shelf life that facilitates importation, celery root can be found year-round in most major grocery stores. Seek it out near other root vegetables like potatoes, onions, turnips, carrots, parsnips and beets. Availability peaks around fall through early spring. Try your local supermarket, natural food market, farmers market or farm stand. Being a relatively obscure vegetable, not all retailers carry celeriac consistently, so you may have to search around a bit.
As a humble, unsung hero of the produce world rather than a trendy superfood, celery root remains highly affordable. Prices typically run between:
- $1 – $3 per pound
- $2 – $4 each for large single roots weighing 1-2 pounds
*Prices may fluctuate based on season, demand and location
Preparation Tips & Handling
Celeriac requires a bit more hands-on prep than most vegetables since the fibrous outer skin and tiny root hairs must be removed. To peel, first slice about 1/4 inch off the top and bottom ends, then stand the cylinder upright and carefully slice downward from top to bottom removing the tough skin in thick strips working around the entire surface. A sturdy vegetable peeler can also work once you peel deep enough past the rootlets.
Beneath lies a smooth white flesh that offers mild resistance when cut, similar to a potato or turnip. If any brownish-green patches remain on the interior flesh, continue peeling deeper until fully removed. Rinse under cool water after peeling to eliminate dirt or debris clinging to crevices. Slice, dice or cut into wedges as desired before use.
When prepping celery root, having a bowl of acidulated water (water mixed with a teaspoon of lemon juice or white vinegar) nearby is recommended to place peeled and sliced pieces into in order to prevent discoloration until ready to cook. Its white flesh will quickly oxidize and turn an unappealing grayish-brown once exposed to air and light if left sitting long.
Sweet yet earthy, the entire celery root can be consumed cooked or raw. However, the taproot and lower hypocotyl offer superior tenderness to the upper neck and shoulders. The tough, fibrous flesh closest to the skin always gets discarded as well. Many recipes suggest salting sliced celeriac before cooking to help draw out excess moisture for better caramelization.
Popular Pairings & Cuisine Contributions
The natural savory herbaceousness of celery root allows it to blend seamlessly into a wide array of cultural dishes spanning from its native French origins to Mediterranean, Middle Eastern and Eastern European cuisines. It also adapts readily to modern applications giving plant-based, gluten-free and paleo diets a new way to rethink root vegetables thanks to celeriac’s lower carb yet nutrient-dense properties.
In Europe, celery root often substitutes for or supplements potatoes. It produces rich stews, gratins and mashed textures with cleaner flavors compared to regular russets or sweet potatoes. Sautéed in butter or olive oil, puréed into velvety soup bases or roasted until tender and caramelized, celeriac exemplifies why the French nickname it “celerisot” – adding notes as delicious as the prized truffle for which it playfully pays homage.
The bright herbal qualities celery root contributes to recipes allows it to accentuate greens, beans, tomatoes, mushrooms and stronger herbs like rosemary, thyme, sage and parsley beautifully. In salads, celeriac’s firm crunch offsets softer lettuces while its slight peppery bite balances fatty, rich ingredients like cheese, nuts and dried fruit. It also makes an excellent candidate for pickling.
Many cultures utilize celeriac in traditional holiday dishes, much like potatoes or turnips. Germans whip up celeriac remoulade for Oktoberfest while French Christmas feasts might feature celery root paired with delicate truffles. It also works well mixed into mirepoix base ingredients of onions, carrots and celery – hence its literal translation as “celery root.”
