Celeriac and celery – they sound similar, they look vaguely alike in some ways, and they’re often found in the produce section together. But are they interchangeable in the kitchen? The short answer is: it depends. While both belong to the same plant family, Apiaceae, and share a distinct flavor profile, their growth habits and culinary uses differ significantly. This article delves into the nuances of celeriac versus celery, exploring their characteristics, flavors, nutritional profiles, and offering guidance on when and how you might substitute one for the other.
Understanding Celeriac and Celery
Let’s start by defining what we’re talking about. Celeriac, also known as celery root, is cultivated for its large, bulbous root. It’s a knobby, earthy-looking vegetable that, once peeled, reveals a creamy white flesh. Celery, on the other hand, is grown for its crisp, juicy stalks. Both share a similar aroma due to the presence of volatile compounds, but their textures and predominant flavors differ noticeably.
Celeriac: The Underground Marvel
Celeriac is essentially a swollen stem base, not a true root like a carrot or parsnip. It has a subtly sweet, celery-like flavor, but with a more pronounced earthy and nutty undertone. This adds depth and complexity to dishes. When raw, celeriac is crunchy and firm, making it suitable for slaws and salads. Cooked, it becomes tender and creamy, lending itself to purees, soups, and gratins.
Celery: The Crunchy Stalk
Celery stalks are what most people think of when they hear the word “celery.” They’re crisp, refreshing, and have a milder, more watery flavor compared to celeriac. Celery is often eaten raw as a snack, used as a crudité with dips, or incorporated into salads for its textural crunch. Cooked, it adds a subtle flavor to soups, stews, and braises. It’s a key component of mirepoix (along with onions and carrots), the foundational flavor base in many cuisines.
Flavor and Texture: Key Distinctions
The most significant difference between celeriac and celery lies in their flavor intensity and texture. Celeriac boasts a bolder, more concentrated celery flavor with a pronounced earthy note. It’s also denser and more substantial. Think of it as celery’s more sophisticated and complex cousin.
Celery, in contrast, is milder and more refreshing. Its high water content contributes to its characteristic crunch. The difference in texture impacts how each vegetable behaves when cooked. Celeriac becomes wonderfully creamy, while celery softens but retains some of its crispness.
Flavor Profiles in Detail
Celeriac offers a complex flavor profile. It is often described as a blend of celery, parsley, and parsnip, with hints of nuttiness and earthiness. The earthy notes become more pronounced when cooked. This depth of flavor makes it a versatile ingredient for adding savory complexity to dishes.
Celery’s flavor is much cleaner and simpler. It is primarily characterized by its fresh, slightly grassy taste. While it does contribute a subtle celery flavor, its main contribution is often its refreshing crunch and moisture.
Nutritional Comparison
Both celeriac and celery are nutritious vegetables, offering a range of vitamins, minerals, and fiber. However, their nutritional profiles differ slightly due to their different plant parts and compositions.
Celeriac is a good source of vitamin K, vitamin C, and several B vitamins. It is also a decent source of minerals like phosphorus, potassium, and manganese. Celeriac contains more fiber than celery.
Celery is lower in calories and carbohydrates than celeriac. It is a good source of vitamin K and also provides vitamin A and folate. Celery contains electrolytes like sodium and potassium, which can contribute to hydration.

When Can You Substitute Celeriac for Celery (and Vice Versa)?
Now, let’s address the central question: can you substitute celeriac for celery, and when is it appropriate? The answer is nuanced and depends heavily on the specific recipe and your desired outcome.
In general, if you’re looking for a strong celery flavor and a creamy texture in a cooked dish, celeriac can be an excellent substitute for celery. If you need a crisp, refreshing crunch and a subtle celery flavor, celery is generally the better choice.
Situations Where Celeriac Works Well as a Substitute
- Soups and Stews: Celeriac adds a richer, more complex flavor to soups and stews than celery. It also thickens the broth slightly as it cooks down. This is particularly useful in creamy soups.
- Purees: Celeriac makes a fantastic puree, either on its own or combined with other root vegetables like potatoes or parsnips. It provides a smooth, creamy texture and a distinctive flavor.
- Gratins: Celeriac can be thinly sliced or grated and layered in gratins for added flavor and texture. It pairs well with cheese, cream, and other vegetables.
- Mashed Potatoes: Adding cooked and mashed celeriac to mashed potatoes elevates the flavor and adds nutritional value.
- Roasted Vegetables: Roasted celeriac develops a sweet, caramelized flavor that is delicious on its own or as part of a mixed roasted vegetable medley.
Situations Where Celery Works Well as a Substitute
- Salads: Celery provides a refreshing crunch and a mild celery flavor to salads. While you could use raw celeriac, it requires more effort to prepare (peeling and grating) and has a stronger, earthier flavor that might not be desirable in all salads.
- Snacks with Dips: Celery sticks are a classic pairing with dips like hummus, guacamole, and ranch dressing. Celeriac is less suitable for this purpose due to its shape and stronger flavor.
- Stir-fries: Celery adds a nice crunch and subtle flavor to stir-fries. While you could use celeriac, it needs to be cooked longer to soften.
- Stuffing (Dressing): Celery is often used in stuffing (or dressing) for poultry. It adds moisture and a subtle celery flavor. Celeriac can be used, but it will result in a denser, more flavorful stuffing.
- Mirepoix: While celeriac can contribute to a mirepoix, celery is more traditional and provides a lighter, brighter flavor.
Important Considerations for Substitution
- Flavor Intensity: Celeriac has a stronger flavor than celery, so use it sparingly at first. You can always add more, but you can’t easily take it away.
- Texture: Celeriac is denser and requires longer cooking times than celery. Adjust cooking times accordingly.
- Preparation: Celeriac requires more preparation than celery. You need to peel the thick outer skin before using it. Celery simply needs to be washed and trimmed.
- Water Content: Celery has a higher water content than celeriac. This can affect the moisture level of your dish, particularly in soups and stews. Adjust liquid levels as needed.
Practical Tips for Using Celeriac and Celery
Here are some practical tips to help you make the most of both celeriac and celery:
- Choosing Celeriac: Select firm, heavy celeriac bulbs with minimal blemishes. Avoid bulbs that are soft or spongy.
- Choosing Celery: Look for firm, crisp celery stalks with bright green leaves. Avoid stalks that are wilted or have brown spots.
- Storing Celeriac: Store celeriac in the refrigerator for up to two weeks. Wrap it tightly in plastic wrap to prevent it from drying out.
- Storing Celery: Store celery in the refrigerator for up to a week. Wrap it tightly in plastic wrap or store it in a container of water.
- Preparing Celeriac: Peel the thick outer skin of celeriac with a sharp knife or vegetable peeler. Cut it into the desired shape (cubes, slices, or grated).
- Preparing Celery: Wash celery stalks thoroughly. Trim off the base and any wilted leaves. Cut into the desired length.

What is the main difference between celeriac and celery?
Celeriac, also known as celery root, is cultivated for its bulbous root, while celery is grown for its stalks. Although they are related (both belonging to the Apiaceae family), they have distinct physical characteristics and flavors. Celeriac’s root is a large, knobby sphere, often covered in dirt, while celery stalks are long, crisp, and fibrous.
While both share a celery-like aroma and taste, celeriac’s flavor is earthier and more intense, with a slightly nutty undertone. Celery, on the other hand, has a lighter, fresher flavor. This difference in flavor profiles impacts how they are used in culinary applications, with celeriac often requiring longer cooking times to mellow its strong taste.
Can I substitute celery for celeriac in a recipe?
In some cases, yes, you can substitute celery for celeriac, especially if the celeriac is meant to add a subtle celery flavor base to soups, stews, or stocks. However, be aware that the flavor will be less pronounced and the texture will be different, as celery stalks cook much faster and become softer than celeriac root. You might need to adjust the amount of celery used to compensate for the less intense flavor of celeriac.
When using celery as a substitute, consider adding other root vegetables like parsnips or carrots to mimic some of the earthy depth that celeriac provides. These additions can help to create a more complex flavor profile closer to the original recipe’s intention. Also, keep in mind the cooking time differences; add the celery later in the cooking process to prevent it from becoming mushy.
Can I substitute celeriac for celery in a recipe?
Substituting celeriac for celery is generally less successful, particularly when the recipe calls for the crisp texture and mild flavor of celery stalks, like in salads or as a raw snack. Celeriac is much tougher and has a significantly stronger, earthier flavor that can easily overpower other ingredients. The texture of cooked celeriac is also different from celery.
If you decide to use celeriac, it will need to be cooked thoroughly to soften its texture and mellow its flavor. Consider using it in purees, soups, or gratins where its robust flavor can complement other ingredients. Use significantly less celeriac than the amount of celery the recipe calls for and taste frequently, adjusting seasonings as needed.
What are the nutritional benefits of celeriac compared to celery?
Celeriac is generally higher in nutrients than celery. It’s a good source of vitamin K, vitamin C, and several B vitamins, as well as minerals like phosphorus and potassium. It also contains a significant amount of fiber.
Celery is lower in calories and a good source of vitamin K and some antioxidants. While it contains fiber, it is less fiber-dense than celeriac. Both are low in fat and cholesterol, making them healthy additions to a balanced diet, but celeriac offers a more concentrated source of several key nutrients.
How do I prepare celeriac for cooking?
Preparing celeriac involves more work than preparing celery. First, thoroughly wash the root to remove any dirt. Then, use a sharp knife to cut off the top and bottom, creating a stable base.
Next, carefully peel away the thick, knobby skin, removing all traces of it. Once peeled, celeriac can be cut into cubes, slices, or sticks, depending on the recipe. It’s important to work quickly, as celeriac can discolor when exposed to air. You can also soak it in water with a little lemon juice to prevent browning.
What are some popular dishes that feature celeriac?
Celeriac is often featured in creamy purees, providing a unique and earthy flavor. It is also a popular addition to soups and stews, lending depth and complexity. Another classic preparation is celeriac remoulade, a French salad made with grated celeriac and a mayonnaise-based dressing.
Beyond these classics, celeriac can be roasted like other root vegetables, offering a slightly sweet and nutty flavor. It can also be used in gratins or mashed with potatoes for a more flavorful alternative to mashed potatoes. Its versatility makes it a valuable ingredient in both vegetarian and meat-based dishes.
How should I store celeriac and celery to keep them fresh?
Celeriac can be stored for several weeks in the refrigerator. Wrap it loosely in a paper towel or place it in a perforated plastic bag to prevent it from drying out. The cooler and more humid the environment, the longer it will last.
Celery, on the other hand, is best stored in the refrigerator wrapped tightly in plastic wrap or submerged in a container of water. This helps to maintain its crispness. Celery typically lasts for about 1-2 weeks when stored properly.
