No, celery root is not a different vegetable from celeriac. Celery root and celeriac are two interchangeable names for the exact same root vegetable. This knobby, earthy vegetable is botanically known as Apium graveolens var. rapaceum.
Many people find the appearance of this vegetable quite intimidating, but beneath its rough exterior lies a delicious and highly versatile ingredient. Learning to embrace celeriac, or celery root, can unlock a world of culinary possibilities, from hearty stews to refreshing salads.
Celeriac and Celery Root Are Indeed the Same Plant
Celery root and celeriac refer to the identical plant, Apium graveolens var. rapaceum. This vegetable is a specific cultivar of wild celery. It is grown for its bulbous, edible hypocotyl, which is often mistakenly called a root.
The plant originated in the Mediterranean Basin and Northern Europe. It has been cultivated for thousands of years. Ancient civilizations, including Egyptians, Romans, and Greeks, used wild celery for medicinal and religious purposes.
Distinguishing Celeriac from Stalk Celery: A Clear Difference
While celeriac shares a botanical relationship with common stalk celery, they are distinct varieties of the same species, Apium graveolens. Farmers cultivate celeriac specifically for its enlarged, edible root-like base. Conversely, traditional celery is grown for its crisp, green stalks and leaves.
Their flavors are similar, but celeriac tends to be more earthy and intense. Stalk celery has a milder, fresher taste. Their textures differ significantly, making them non-interchangeable in most recipes.
Chefs often use celery stalks for their crunch in salads or as an aromatic base in cooking. Celeriac offers a dense, potato-like texture when cooked, suitable for mashing or pureeing.
Here is a comparison between Celeriac and Stalk Celery:
| Feature | Celeriac (Celery Root) | Stalk Celery |
|---|---|---|
| Edible Part | Bulbous, knobby root (hypocotyl) | Long, green, crisp stalks and leaves |
| Appearance | Ugly, misshapen, off-white, with rough, hairy skin | Long, straight, green stalks |
| Flavor Profile | Earthy, nutty, subtle celery, slightly sweet when cooked | Fresh, herbal, classic celery flavor |
| Texture (Raw) | Crunchy, firm, fine-grained flesh | Crisp, juicy, stringy |
| Texture (Cooked) | Creamy, dense, slightly fibrous | Mellow, soft, retains some crunch |
| Typical Uses | Mashed, roasted, pureed, added to soups, raw in salads | Salads, snacking, mirepoix, soups, stir-fries |
Nutritional Profile of Celeriac: A Healthy Choice

Selecting and Storing Celeriac: Expert Tips for Freshness
Selecting a good celeriac is key to enjoying its best flavor and texture. Look for firm, heavy roots that are relatively smooth. Avoid specimens with soft spots or significant blemishes.
Smaller celeriac bulbs generally have a better inner flesh. A heavy root for its size indicates solid flesh, not a porous interior.
To store celeriac, keep it whole and unwashed. Wrap it loosely in a plastic bag or paper towel. Store it in the refrigerator’s crisper drawer. It can last several weeks, and up to 3-6 months in optimal cool, damp conditions. Once cut, soak celeriac in acidulated water to prevent discoloration.
Preparing Celeriac for Cooking: Essential Steps
Preparing celeriac can seem daunting due to its irregular shape and tough skin. A sharp chef’s knife is more effective than a vegetable peeler for the initial trimming.
First, wash the celeriac thoroughly to remove dirt. Then, trim off the top and bottom ends to create flat, stable surfaces. Place the celeriac on one flat end and carefully slice downwards to remove the thick, knobby skin. Expect some wastage as you carve away the irregular exterior.
Once peeled, its white flesh can oxidize quickly, similar to apples or potatoes. Submerge cut pieces in water with a splash of lemon juice or vinegar to prevent browning.
Culinary Uses of Celeriac: Versatility in the Kitchen
Celeriac’s subtle celery-like flavor, combined with its creamy texture when cooked, makes it incredibly versatile. It is a popular ingredient in Eastern and Northern European cuisine.
Raw celeriac is excellent grated into salads or slaws. Its crisp texture adds a refreshing bite.
Cooked, celeriac transforms into a tender, slightly sweeter vegetable. It can be roasted, baked, boiled, or mashed. Many home cooks use it as a low-carb alternative to potatoes. It creates creamy purees and mashes.
Celeriac also shines in soups, stews, and gratins. Its earthy notes complement other root vegetables.
Chef Jamie Oliver once called celeriac “the most underrated vegetable in the whole of the United Kingdom.” Its subtle hazelnut flavor develops with cooking.
