The Knobbly Underdog: Why Celeriac Deserves the Best Seat at Your Winter Table

Every November the same quiet injustice plays out at the market: people walk straight past the knobbly beige thing in the corner and head for the butternut squash. I understand it. Celeriac looks like something that grew wrong. It is heavy, hairy, faintly grubby, and it has a smell that travels. But I would happily argue, over a bowl of soup, that it is the most useful vegetable on a British winter table.

In defence of the ugly ones

Celeriac is not a fashionable ingredient, and that is almost the point. It is grown here — Lincolnshire, Lancashire, Somerset and plenty of smaller holdings — it is lifted from October onwards, and it sits happily in a cold shed or the bottom of the fridge for weeks without complaining. A decent head costs somewhere between £1.50 and £2.50 at a farmers' market, and one will feed four people generously as a side, or two as a main with bread and a bit of cheese.

Compare that to the air-freighted, plastic-wrapped alternatives and the case makes itself. What it lacks in beauty it makes up for in range: the same root can be a crunchy salad on Tuesday, a Sunday roast accompaniment and a silky purée on Thursday.

Choosing one at the market

A few growers have given me the same advice, more or less word for word, so I will pass it on.

Pick it up. It should feel dense and heavy for its size — a light celeriac is a dry, spongy celeriac. Look for tight, firm skin with no soft patches, and skip any with dampness or mould around the base where the roots were trimmed. The little rooty nodules are normal; hairy is fine, slimy is not.

Size is a red herring. A medium head, somewhere between a large apple and a grapefruit, is easiest to handle and cooks evenly. If you are roasting it whole, smaller is safer.

Ask when it was lifted. A grower will tell you, and the answer is usually 'this week', which is one of the small pleasures of shopping this way. Do buy it loose if you can — the vacuum-packed halves are convenient but you lose the chance to judge the thing for yourself.

Prep without the swearing

The one genuine obstacle is the peeling. Celeriac skin is thick, gnarly and full of grit, and a vegetable peeler will simply bounce off it.

Use a knife. Top and tail the root flat so it sits still, then cut down the sides in firm strokes, following the curve, taking off the skin and the woody layer just beneath it. You will lose more than you expect; that is normal. Cut it into slabs or chunks as you go and drop the pieces into water with a good squeeze of lemon in it, because celeriac browns quickly once the air gets to it.

Keep the peelings and trimmings for stock — they carry a lot of flavour — and keep the prepared root in acidulated water until you are ready to cook.

Three ways to cook it, three different vegetables

1. Raw remoulade — the crunch

This is the version that converts people. Julienne about 500g of peeled celeriac — a mandoline if you have one, a sharp knife and some patience if you do not. Toss with three tablespoons of mayonnaise, a tablespoon of Dijon mustard, a tablespoon of lemon juice, a good pinch of salt and plenty of black pepper, then leave it for twenty minutes. The salt softens it just enough while keeping the squeak.

Finish with parsley, capers, a little grated horseradish if you like, or a handful of toasted hazelnuts. It sits beautifully next to cold ham, smoked fish or a plain roast chicken.

2. Whole-roasted — the sweet one

Rub a whole, unpeeled head with oil and salt, wrap it tightly in foil and roast at 200°C fan for an hour and a half to two hours, until a knife slides in with no resistance. Unwrap, turn the heat up, and give it another twenty minutes to colour and caramelise at the edges.

Cut it into wedges, spoon over brown butter with thyme and a clove of garlic, and serve it as you would a roast potato. The celery edge softens and something sweeter, almost chestnutty, comes through.

3. Silky purée — the comfort one

Peel and chunk a head, then simmer it gently in milk with a bay leaf, a couple of garlic cloves and salt for about twenty minutes. Drain, keeping the liquid, and blitz with butter and a splash of the cooking milk until completely smooth. Push it through a sieve if you want the restaurant version. It is the best thing under a pie, alongside game, or under a pile of buttery mushrooms.

Honest taste notes

Celeriac tastes like celery that went to seed in a good way, with a parsnip-ish sweetness underneath. Raw, the first note is green and slightly bitter; then it turns nutty. Cooked, the bitterness goes and the sweetness moves forward.

The smell is stronger than the flavour. If you can smell it across the kitchen, do not panic — a lot of that blows off in cooking.

It takes more salt than you think. This is the single most common mistake. Season, taste, season again. A squeeze of lemon or a splash of vinegar does more for it than any spice; without acid, celeriac can taste a bit muddy and flat.

A pairing guide for November 2026

Keep it simple and it will behave.

• With fat: butter, cream, olive oil, goose fat, mayonnaise. Celeriac needs richness.
• With acid: lemon, cider vinegar, mustard, capers, pickled walnuts.
• With nuts and cheese: hazelnuts, walnuts, Stilton, mature Cheddar, Comté.
• With herbs: thyme, bay, parsley, sage, chervil.
• With fruit: apple, pear, quince.
• With meat and fish: roast chicken, game, ham hock, smoked haddock, pork.

It does not need much chilli or spice; a little nutmeg or cracked black pepper goes considerably further than heat.

The case for a bit more ugly veg

Celeriac will never win a beauty contest, and it does not need to. It is cheap, British, long-lasting, and it does three completely different things well. That is a better CV than most of what ends up in our baskets in November.

Buy one this week. Peel it with a knife rather than a peeler, salt it more than feels sensible, and see what happens.
