Celery root, also known as celeriac, is a unique and often overlooked member of the plant kingdom, frequently overshadowed by its more popular relatives like traditional celery. This fascinating root vegetable is rich in flavor and nutrition, making it a valuable addition to our diets. In this article, we will delve deep into the taxonomy of celery root, uncovering not just what part of the plant it is, but also its uses, benefits, cultivation, and culinary versatility.
Understanding Celery Root: The Basics
Celery root, or celeriac (Apium graveolens var. rapaceum), belongs to the Apiaceae family, which also includes carrots, parsley, and fennel. Unlike its cousin, the common celery (Apium graveolens), which is grown primarily for its stalks and leaves, celery root is cultivated for its bulbous, edible root. This unique structure is not only a staple in various culinary dishes but also a nutritional powerhouse.
The Anatomy of Celery Root
To comprehend the nature of celery root, it’s essential to understand the structure of the plant. The celery plant can be divided into several key components:
- Roots: The underground portion that anchors the plant and absorbs nutrients and water.
- Stem: The aboveground part that supports leaves and flowers, contributing to the plant’s overall structure.
- Leaves: The green, leafy parts that perform photosynthesis and contribute to the plant’s growth.
- Flowers: The reproductive structures that eventually develop into seeds.
The notable characteristic of celery root is that it is the swollen, fleshy part of the plant’s taproot. This means that the primary edible component we refer to as celery root is essentially a modified root designed by the plant to store nutrients.
What Makes Celery Root Unique?
Celery root’s uniqueness stems from its flavors and textures. While it resembles a knobby, rough potato on the outside, the inside reveals a creamy white flesh that has a mild, slight sweetness reminiscent of its stalk counterpart but with an earthy, nutty undertone. Understanding what celery root is and how it forms can help us appreciate its role in our diets and its culinary potential.

What is celery root?
Celery root, also known as celeriac, is a variety of celery cultivated for its edible bulbous root rather than its stalks.

Celery root belongs to the Apiaceae family, which also includes carrots, parsley, and fennel, making it a close relative of common celery.
While commonly used in European cuisine, especially in French recipes, celery root is gaining popularity in other parts of the world due to its versatile taste and numerous health benefits. It can be eaten raw in salads, mashed like potatoes, or roasted to enhance its nutty flavor. This fascinating vegetable is a wonderful ingredient in soups, stews, and purées, making it a delectable addition to a variety of dishes.
Is celery root the same as regular celery?
No, celery root is not the same as regular celery, although they are closely related. Regular celery (Apium graveolens) is primarily cultivated for its long, crisp stalks, which are often used in salads, soups, and as snacks. In contrast, celery root (Apium graveolens var. rapaceum) is specifically grown for its bulbous root, which has a different texture and flavor profile.
While both types of celery share a similar fragrant taste, celery root is known for its earthy, nutty flavor, which becomes sweeter when cooked. Its unique texture makes it an excellent substitute in many recipes that call for potatoes or turnips, providing a lower-calorie, nutrient-rich option for home cooks and chefs alike.
How do you prepare celery root for cooking?
Preparing celery root for cooking is a straightforward process. First, you’ll need to wash the outer surface thoroughly to remove any dirt or debris. Once clean, use a sharp knife or a vegetable peeler to remove the rough, brown skin, taking care to discard any blemished areas. Cutting the root into manageable pieces will make it easier to cook.
After peeling, celery root can be diced, sliced, or grated depending on the recipe you are following. It can be used raw in salads for a crunchy texture or cooked in various ways, such as boiling, roasting, or sautéing. Cooking methods can enhance its natural sweetness and flavor, transforming it into a delicious addition for many dishes.
What are the nutritional benefits of celery root?
Celery root is a nutrient-dense vegetable, which makes it an excellent addition to a balanced diet. It is low in calories yet rich in vitamins and minerals, providing a substantial amount of vitamin K, vitamin C, and several B vitamins. Additionally, celery root contains potassium, which is essential for heart health and maintaining proper fluid balance in the body.
Furthermore, celery root is a good source of dietary fiber, which aids in digestion and helps maintain healthy gut function. The presence of antioxidants in celery root can help reduce inflammation and combat oxidative stress in the body. Therefore, incorporating celery root into your meals contributes to overall health and well-being.
Can you eat the leaves of celery root?
Yes, the leaves of celery root, often referred to as celeriac leaves, are edible and can be used in various culinary applications. These leaves have a strong, celery-like flavor, which makes them a great addition to salads, soups, and stir-fries. They can also be used as a garnish, adding both color and a burst of flavor to dishes.
However, it’s essential to ensure that the leaves are fresh and free from any signs of wilting or decay. While the leaves are not commonly consumed due to the focus on the root, they offer a wonderful way to reduce waste and make the most out of the entire plant. Additionally, the leaves can be used to create flavorful stocks or as a seasoning in cooking.
Where can you find celery root in stores?
Celery root can typically be found in the produce section of grocery stores, especially those that have a good selection of fresh vegetables. Although it may not be as commonly stocked as other root vegetables, you may have better luck in stores that focus on organic or specialty produce. Farmers’ markets are another excellent place to find fresh celery root directly from local growers.
If celery root is not immediately available in your local grocery store, you can also consider checking online retailers or specialty food stores. Some stores offer the option to pre-order vegetables or can let you know when they’ll be restocked. Seasonal availability varies, but celery root is often more prevalent in the fall and winter months when root vegetables are at their peak.
