Celery root, also widely known as celeriac, is a fascinating and often overlooked root vegetable that offers a unique flavor and texture profile to a wide array of dishes. Despite its unappealing, knobby exterior, this earthy gem is not the root of the common stalk celery we typically munch on, but rather a distinct variety of the same plant family, specifically cultivated for its enlarged, edible stem base. Its creamy white interior holds a subtle, savory taste, making it a versatile ingredient in both raw and cooked applications.
For too long, celery root has lurked in the shadows of the produce aisle, intimidating home cooks with its rugged appearance. However, embracing this “ugly-delicious” vegetable unlocks a world of culinary possibilities, from light, refreshing salads to hearty, comforting mashes and soups. Let’s dig in and discover everything you need to know to transform this unassuming ingredient into a star in your kitchen.
What Does Celery Root Look Like and Taste Like?
Celery root presents a rough, gnarled, and often mud-flecked exterior, typically off-white to light brown in color. It’s roughly round, resembling a misshapen turnip, and can range in size from an apple to a small cantaloupe, usually weighing 1–2 pounds. Tiny rootlets cover its surface, contributing to its intimidating appearance.
Beneath its thick, fibrous skin lies a smooth, dense, creamy white flesh. When eaten raw, celery root has a crunchy texture, similar to a radish, offering a delicate freshness. Its flavor is mild, faintly aromatic, and has been described as a combination of celery and parsley with a nutty undertone and a slight sweetness. Cooked celery root becomes softer, silkier, and slightly sweeter, with a deeply savory flavor that enhances many dishes.
Where Does Celery Root Come From and How Is It Grown?
Celery root, scientifically known as Apium graveolens var. rapaceum, originated in the Mediterranean Basin. Its ancestors, wild celery, were recognized for both medicinal and religious purposes by ancient civilizations in Egypt, Rome, and Greece. The term “selinon” used by ancient Greeks referred to both wild celery and parsley.
Cultivation of celery root, distinct from stalk celery, gained culinary importance during the Middle Ages in Europe. It is a cool-season vegetable with a long growing season, typically harvested in late fall and available throughout the cooler months, from September to April. Unlike its familiar green relative, celery root is specifically bred for its swollen stem base rather than its celery stalks or leaves, which are often more fibrous and intensely flavored.
Nutritional Powerhouse: The Impressive Benefits of Celery Root
Despite its humble looks, celery root is a nutritional powerhouse. It is a low-calorie, low-carb root vegetable packed with essential vitamins, minerals, and antioxidants.
- Rich in Vitamins: Celery root is an excellent source of Vitamin K, crucial for bone health and blood clotting. It also provides significant amounts of Vitamin C, an antioxidant that boosts the immune system and protects against cell damage, and Vitamin B6, important for cognitive development and metabolism.
- Abundant in Minerals: This root vegetable supplies vital minerals such as potassium, which helps regulate blood pressure and reduce stroke risk, and phosphorus, essential for strong bones. It also contains manganese, magnesium, iron, and calcium.
- High in Fiber: Celery root is a good source of dietary fiber, supporting healthy digestion, promoting satiety, and helping stabilize blood sugar levels. Prebiotic fibers in celeriac nourish beneficial gut bacteria.
- Antioxidant Properties: It is rich in antioxidants that fight against harmful free radicals, potentially protecting against chronic conditions like heart disease, cancer, and Alzheimer’s, and offering anti-aging effects.
- Low in Calories and Carbs: With only about 40-66 calories and 14.4 grams of carbohydrates per cup (raw or chopped), celery root serves as an excellent low-carb alternative to potatoes and other starchy root vegetables, making it beneficial for weight management.
Registered dietitian Sharon Palmer, “The Plant-Powered Dietitian,” notes, “Celeriac is truly an underrated vegetable. It offers a unique flavor and a powerful nutritional punch, making it a smart choice for anyone looking to diversify their diet with healthy, plant-based options.”
How to Choose and Store Celery Root for Optimal Freshness
Selecting the best celery root is crucial for a great culinary experience. Look for firm, heavy roots that feel solid for their size. Avoid any with soft spots, blemishes, or excessive dirt and rootlets, though some dirt is common. A medium-sized celery root, around 4–5 inches in diameter, is often preferred, as larger ones can sometimes have hollow or fibrous cores.
Proper storage ensures your celery root stays fresh for weeks or even months. Remove any attached greens, as they can draw moisture away from the root. Store the unwashed celery root loosely wrapped in a paper towel inside a plastic bag in your refrigerator’s crisper drawer. It can keep for up to three months, or even longer in optimal conditions (like a root cellar). Once cut, however, aim to use it within 3–5 days to maintain freshness and prevent browning.
Prepping Celery Root: The Nitty-Gritty of Peeling and Cutting
Prepping celery root can seem daunting due to its irregular, knobby surface, but it’s simpler than it looks. The skin is too tough and fibrous to eat and must be removed.
Here’s a straightforward method for peeling and cutting celery root:
- Stabilize the Root: Start by cutting off the top and bottom ends of the celery root to create flat, stable surfaces. This allows the root to sit securely on your cutting board, preventing it from rolling while you work.
- Remove the Skin: Use a sharp chef’s knife or a strong paring knife, rather than a standard vegetable peeler, to remove the thick, rough skin. Think of it like peeling a pineapple or carving away armor. Slice downwards, following the curve of the root, removing thick strips of skin until only the creamy white flesh remains. Don’t be shy about removing any recessed or pocked parts.
- Address Discoloration: Celery root oxidizes quickly and will turn brown once peeled and exposed to air, similar to an apple or potato. To prevent this, immediately submerge the peeled or cut pieces in a bowl of water mixed with a tablespoon of lemon juice, or rub the exposed surfaces with a cut lemon.
- Cut as Needed: Once peeled, you can cut the celery root into halves, wedges, slices, matchsticks, or cubes, depending on your recipe. Remove any soft, cottony flesh you might find in the center of larger pieces.
Chef Evan Kleiman, known for her radio show “Good Food,” advises, “Peeling it is the biggest challenge, which is why most people shy away from the knobby thing. It isn’t difficult to do, but it does require attention since it’s so uneven on the outside.”
Cooking with Celery Root: Versatile Culinary Uses
Celery root’s subtle flavor and adaptable texture make it incredibly versatile in the kitchen. It can be enjoyed raw or cooked, serving as a delicious and healthier alternative to potatoes in many dishes.
Here are some popular and genuinely delicious ways to incorporate celery root into your meals:
Raw Celery Root Applications
When raw, celery root adds a refreshing crunch and unique flavor to salads and slaws.
- Céleri Rémoulade: This classic French dish involves julienned or grated celery root tossed with a creamy, mustardy mayonnaise dressing, lemon juice, and black pepper. It’s crunchy, sharp, and incredibly refreshing.
- Winter Salads: Thinly sliced matchsticks or grated celery root pair wonderfully with ingredients like apples, pears, walnuts, blue cheese, and endive.
- Crudité: Serve raw celery root sticks with dips like hummus for a healthy snack.
Cooked Celery Root Delights
Cooking transforms celery root into a silky, slightly sweeter, and deeply savory vegetable.
- Mashed Celery Root: A fantastic low-carb alternative to mashed potatoes, it creates a lighter, more aromatic mash. Combine it with butter, cream, or even other root vegetables like parsnips or potatoes for added depth.
- Roasted Celery Root: Roasting brings out its mellow sweetness and creates delicious caramelization. Cut into chunks, cubes, or thick slabs (for “steaks”), toss with olive oil, salt, herbs like thyme or rosemary, and roast until tender and golden brown.
- Creamy Soups and Stews: Celery root shines in creamy pureed soups, offering a subtle celery-like flavor and velvety texture. It also adds a wonderful earthy note to hearty stews and casseroles.
- Celery Root Fries or Chips: Thinly slice celery root with a mandolin, toss with olive oil and salt, and bake for homemade, healthy chips. Alternatively, cut into thicker fries and roast or fry.
- Gratins: Layer sliced celery root with potatoes, cheese, and cream for a rich and comforting gratin.

Expert Tips for Mastering Celery Root
Leveraging insights from culinary professionals can elevate your celery root dishes. Here are a few expert tips to keep in mind:
- Don’t Be Afraid of the Knife for Peeling: As Chef Evan Kleiman advises, a sharp chef’s knife is often more effective than a vegetable peeler for its rugged exterior. Slice off the ends for stability and then carve away the skin in thick strips.
- Embrace Acidity: To combat browning, always have lemon water ready for peeled or cut celery root. “The exposed flesh will turn brown quickly, so if you wish to retain the white color, rub it with a cut lemon or have a bowl of water mixed with a tablespoon of lemon juice to submerge the pieces in as you cut them,” suggests The Kitchn.
- Season Generously: Celery root’s earthy, subtle flavor benefits from bold seasonings. Think herbs like thyme, rosemary, parsley, and dill. Spices such as cumin, nutmeg, and even a touch of cinnamon or allspice can enhance its profile.
- Consider its “Ugly Delicious” Charm: Farmer Lee Jones of The Chef’s Garden refers to celery root as “one of the most underrated veggie around.” Don’t let its looks deter you; its flavor and versatility are its true beauty.
- Pair Thoughtfully: Celery root pairs exceptionally well with apples, pears, walnuts, Dijon mustard, and various cheeses like Gruyere or blue cheese. Its flavor also complements seafood and roasted meats.
- Vary Cooking Methods: Experiment with different techniques. While roasting brings out sweetness, pureeing creates a silky base, and serving it raw adds a crisp texture.
