What is Celeriac?

Celeriac, also known as celery root, is a root vegetable that belongs to the same family as celery. Despite its name, celeriac is not the root of the celery plant but rather a distinct vegetable on its own. It is characterized by its knobby, irregularly shaped root with a rough, tan-colored outer skin. The inner flesh is creamy white and has a firm and dense texture.

Celeriac has a unique flavor that combines the subtle taste of celery with hints of parsley and nuttiness. It offers a pleasant crunch when eaten raw and becomes tender and creamy when cooked. Although it may appear a bit unappealing due to its rugged appearance, celeriac is highly versatile and can be enjoyed in a variety of cooked and raw preparations.

Essentially celeriac is much like a potato or a swede, and can be cooked in many of the same ways. However, to get specific, here is a look at some of the best ways to cook and prepare it to get the most out of its flavours and its health benefits.


Roasting celeriac enhances its natural sweetness and creates a delightful caramelized flavour. To roast celeriac, preheat your oven to 200°C. Peel and cut the celeriac into cubes or wedges, toss them with olive oil, salt, and pepper, and spread them out on a baking sheet. Roast for approximately 30-40 minutes, turning occasionally, until the celeriac is tender and golden brown. The result is a heavenly side dish or a delicious addition to salads and grain bowls.


Celeriac can be transformed into a creamy and flavorful mash, providing a unique twist to traditional mashed potatoes. Peel and cube the celeriac, then boil it in salted water until tender. Drain the cooked celeriac and mash it with butter, cream, or vegetable broth. Season with salt, pepper, and herbs such as thyme or rosemary. This velvety celeriac mash pairs wonderfully with roasted dishes or can be enjoyed as a comforting standalone side.

Soups and Purees

Celeriac shines in soups and purees, adding depth and richness to every spoonful. Start by peeling and dicing the celeriac. Sauté onions, garlic, and celery in a pot until softened, then add the celeriac and vegetable or chicken broth. Simmer until the celeriac is tender, then puree the mixture until smooth. Season with herbs, spices, and a touch of cream for a velvety texture. Enjoy this warm and comforting celeriac soup on chilly days or as an elegant starter for dinner parties.

Celeriac Fries

Crispy and flavourful celeriac fries are a delicious and healthier alternative to traditional potato fries. Peel the celeriac and cut it into thin matchstick-shaped pieces. Toss them in olive oil, salt, and your favorite seasonings, such as paprika or garlic powder. Arrange the coated celeriac sticks in a single layer on a baking sheet and bake at 220°C for approximately 20-25 minutes, flipping halfway through. Serve these irresistible fries as a side dish or a tasty snack.


Celeriac gratin is a decadent and comforting dish that showcases the root vegetable’s unique flavor. Slice the peeled celeriac into thin rounds and layer them in a baking dish. Pour a mixture of nut milk seasoned with herbs, garlic, and grated vegan cheese over the celeriac. Bake at 190°C for about 40-45 minutes until the celeriac is tender and the top is golden and bubbly. Indulge in the creamy and cheesy goodness of celeriac gratin as a satisfying accompaniment to roasted meats or as a vegetarian centerpiece.


Celeriac can add a delightful crunch and flavor to stir-fries. Cut the peeled celeriac into thin strips or matchsticks. Heat oil in a wok or skillet, add your favorite vegetables, such as bell peppers, carrots, and onions, and stir-fry until crisp-tender. Toss in the celeriac and cook for a few minutes until slightly softened. Add soy sauce, ginger, garlic, and any other desired seasonings for an extra burst of flavor. Stir-fry for a minute or two more, ensuring the celeriac retains its crunch. Serve this vibrant and nutritious stir-fry over rice or noodles for a satisfying and wholesome meal.

Buying and Storing Celeriac
