How to Cook Celeriac: From Root to Dish

Celeriac, also known as celery root, is a vegetable that is closely related to celery. It has a unique flavor that is slightly nutty and a texture that is similar to potatoes. Celeriac is often used as a substitute for potatoes or other root vegetables in recipes. In this article, we will explore the many ways in which you can cook celeriac, from root to dish.

What is celeriac?

Celeriac is a root vegetable that is often used in cooking. It is a member of the celery family and is grown for its edible roots. Celeriac has a knobby, irregular shape and is covered in a thick, rough skin. The flesh of the celeriac is white and has a firm, crisp texture. The flavor of celeriac is often described as earthy, with a slight nuttiness.

How to choose and prepare celeriac

Choosing celeriac

When choosing celeriac, look for a vegetable that is firm and heavy for its size. The skin should be free of blemishes and cuts. Celeriac is available year-round, but it is at its peak from late fall to early spring.

Preparing celeriac

To prepare celeriac, begin by washing and scrubbing it thoroughly. You may need to use a vegetable brush to remove any dirt or debris that is stuck to the skin. Once the celeriac is clean, use a sharp knife to remove the top and bottom of the root. Then, use a vegetable peeler to remove the skin.

After you have peeled the celeriac, you can cut it into cubes, slices, or wedges, depending on the recipe you are making.

Ways to cook celeriac

Roasting celeriac

Roasting celeriac is a simple and delicious way to prepare this root vegetable. To do this, preheat your oven to 400°F. Cut the celeriac into cubes, toss them with olive oil, salt, and pepper, and spread them out in a single layer on a baking sheet. Roast for 25-30 minutes, or until the celeriac is tender and golden brown.

Mashing celeriac

Celeriac can be mashed just like potatoes. To do this, cut the celeriac into cubes and boil them in salted water until they are tender. Drain the celeriac and mash it with butter and milk until it is smooth and creamy. Season with salt and pepper to taste.

Braising celeriac

Braising celeriac is another great way to prepare this root vegetable. To do this, heat a small amount of oil in a large skillet over medium heat. Add the celeriac cubes and sauté for a few minutes, until they are lightly browned. Add a small amount of water or broth to the skillet and cover with a lid. Simmer for 20-25 minutes, or until the celeriac is tender.
