How to Cook Celeriac: Easy and Delicious Ideas

Celeriac, also known as celery root, is one of those vegetables that often gets overlooked — yet it’s wonderfully versatile, flavourful, and packed with nutrients. Its slightly nutty, earthy taste makes it a great companion to winter dishes and festive meals.

If you’ve ever wondered how to cook celeriac or what to make with it, this guide has everything you need to know.

What is Celeriac and What Does It Taste Like?

Celeriac is the bulbous root of the celery plant, known for its rough, knobbly skin and pale, firm flesh. Its taste is like a subtle mix of celery and parsley root — aromatic and fresh, yet creamy when cooked.

It’s naturally low in carbs and calories, making it a great alternative to potatoes in purées, soups, or gratins.

How to Prepare Celeriac Before Cooking

Before cooking celeriac, it’s important to peel it properly — the outer skin is thick and uneven.

Steps to prepare:

1. Cut off the top and bottom to create a flat surface.
2. Use a sharp knife to trim away the rough skin.
3. Rinse, then cut into cubes, slices, or matchsticks depending on your recipe.

Tip: To prevent browning, place the peeled pieces in a bowl of water with a splash of lemon juice.

Cooking Methods: From Roasting to Mashing

There are many ways to cook celeriac — each brings out a different flavour and texture.

Roasted Celeriac

Toss chunks of celeriac with olive oil, salt, pepper, and herbs like thyme or rosemary. Roast at 200°C (400°F) for 30–40 minutes until golden and caramelised.
👉 Try it alongside your favourite roast dinner or prime rib for a comforting side.

Mashed Celeriac

Boil chopped celeriac until tender (about 20 minutes). Mash with butter, cream, and a little nutmeg for a lighter version of mashed potatoes.
You can also mix it half-and-half with potato for a smoother flavour.

Celeriac Soup

Simmer diced celeriac with onions, garlic, and vegetable stock. Blend until creamy and top with crispy bacon or croutons for texture.

Celeriac Gratin

Layer thinly sliced celeriac with cream, cheese, and herbs, then bake until bubbling and golden. It’s a luxurious side dish for Christmas dinner or any weekend meal.

Creative Ideas with Celeriac

Celeriac isn’t just for soups or mash — try it in unexpected ways:

• Celeriac fries – oven-baked or air-fried with smoked paprika.
• Celeriac slaw – grated raw and tossed with lemon mayo or mustard dressing.

If you’re already planning your festive table, pair celeriac with classics like roast potatoes, buttered Brussels sprouts, or Yorkshire pudding for a comforting and seasonal twist.
It also pairs beautifully with roast lamb, beef Wellington, or pan-fried salmon.
