Whole Celeriac Baked Six Hours, and Pulled Apart the Same Way

A whole celeriac baked in salt and cider until it is dark, dense and torn open with two forks at the table, with the same bread-thickened sauce as the lamb it stands beside.

Pairing
Wine — A lightly oxidative white with age on it — a Jura Chardonnay, or a traditional white Rioja. The nutty, faintly mushroomy edge meets the porcini in the sauce halfway, and there is enough acid left to handle the cider. Mixed drink — A mezcal paloma, salt on the rim, built long with pink grapefruit. Smoke against a sweet root vegetable is the pairing worth making here, and the grapefruit's bitterness keeps a rich brown sauce from settling on the palate. Teetotaler — Verjus over ice with cold soda and a wide strip of grapefruit peel twisted hard over the glass. Verjus is unripe grape juice, so it does the acid-and-tannin job of a wine with none of the sugar that makes most alcohol-free options taste like a compromise at the main course.

Tools
A stiff vegetable brush, since these are knobbly and hold soil in the root and they cook unpeeled, a long skewer for both piercing and testing, a wide pan for the onions, a deep casserole with a genuinely tight lid — foil underneath it if the fit is only approximate, because six hours of escaping steam leaves you with a dry pot by hour four — a sieve for the liquor, a stick blender, a serving pot that matches whatever the meat is arriving in, and two forks. Six uninterrupted hours of oven at 150°C is the real piece of equipment here, and it is the one you have to book

Ingredients · swaps in parentheses
Two large celeriac of similar weight (whole hispi or sweetheart cabbage halved works on the same braise in two hours and pulls into leaves rather than strands, swede or a big kohlrabi wants five hours and an extra tablespoon of vinegar because it is sweeter), olive oil, coarse sea salt for the outside — fine salt is the wrong tool, it penetrates rather than sitting on a skin you are going to throw away — onions, garlic, bay, black peppercorns, thyme, dry cider, a vegetable stock with some actual backbone built on dried mushroom and roasted onion skin, dried porcini or light miso for depth, stale dark-crusted bread (80 g of dry-toasted buckwheat groats instead makes the pot vegan and gluten-free at once), and cider vinegar

Magic
Buy one extra celeriac, small, and leave it raw. Ten minutes before service, peel it and shave it into fine ribbons on a mandoline or with a peeler, toss them with the juice of a lemon, a good pinch of salt and a lot of roughly torn flat parsley, and let them sit — the acid takes the raw edge off and stops them browning. Scatter that over the pulled celeriac as it goes to the table. Same vegetable twice, six hours apart: dense sweet strands underneath, cold sharp crunch on top, and the contrast does what a squeeze of something bright cannot, because it is texture as well as acid. It also solves the quiet problem with long-baked roots, which is that everything in the bowl is the same softness. Not up for a second vegetable? Coarsely chopped parsley with the zest of a whole lemon, thrown over at the last second, gets you part of the way.

Before you begin
Six hours, not four — four gives you a perfectly nice baked celeriac and not this dish, and the tell is that the flesh at the skewer holes looks glassy rather than white. Check the pot at four hours and top it up with 200 ml of water if the liquid has fallen below a third of the way up. The onions are the only browning in the whole recipe and they are carrying the sauce on their own, so take them to properly golden and collapsed, not pale and translucent. Then salt the finished sauce harder than instinct says: a vegetable sauce needs more than a meat one, and under-salting is where most vegan mains quietly fail. Make the sauce on the night, because blitzed bread keeps setting overnight and turns pasty. And send it out at the same moment, in the same style of pot, as whatever else is arriving — ninety seconds late from a different direction tells the whole table something you did not mean to say.

This is the vegetarian and vegan main course, and the important thing about it is what it is not. It is not a plate assembled while everybody else is served from a pot. It arrives in the same kind of vessel, at the same minute, whole and dark and steaming, and it is torn apart with two forks in front of the table in exactly the same gesture as the lamb. Somebody announces it by its own name. Nobody says the word alternative.

Celeriac earns this rather than being awarded it. Given six hours of covered heat it stops behaving like a root vegetable: the flesh goes translucent and dense, almost meaty in the mouth, the sugars caramelize inside the skin, and it tears in fibrous strands instead of crumbling. The thing that decides whether it works is time. Four hours gives you a nice baked celeriac. Six gives you the dish.

Yield and timing

Yield: one large celeriac serves 4 to 5 as a main with sides. Written as two celeriac for a table of 24 where 8 to 10 people are eating this, alongside barley, cabbage and potatoes. Scale by heads, not by table.

Time: 30 minutes active, 6 hours in the oven, 20 minutes resting. Make-ahead: bake the day before and reheat.

Vegan as written.

Ingredients

2 large celeriac, about 2½ lb each, whole, unpeeled, scrubbed hard with a brush
¼ cup olive oil
2½ tbsp coarse sea salt, for rubbing the outside (coarse, not fine — it stays on the skin instead of penetrating, and the skin is discarded)
4 large onions, about 1¾ lb, sliced thickly
1 head of garlic, halved across
4 bay leaves, 1 tbsp black peppercorns, cracked, 3 sprigs thyme
750 ml dry cider
1⅔ cups well-flavored vegetable stock — make it with dried mushroom and roasted onion skin if you can, because this sauce has no meat to lean on
¾ oz dried porcini or 2 tbsp light miso, for depth
2½ cups stale dark-crusted bread, torn (or ½ cup toasted buckwheat groats for the gluten-free version)
2 tbsp cider vinegar, fine sea salt to taste

Method

Heat the oven to 300°F. Scrub the celeriac thoroughly — they are knobbly and hold soil in the roots, and you are cooking them whole with the skin on. Trim the hairy root end flat so they sit still.
Rub each one all over with olive oil and then with the coarse salt, pressing it into the crevices. Pierce each in four places with a skewer, right to the center.
Cook the onions in a wide pan with oil and a pinch of salt for 15 to 18 minutes, until collapsed and properly golden — not pale, not translucent. This is the only browning in the dish and it is carrying the whole sauce.
Add garlic, bay, pepper, thyme, porcini or miso, then the cider. Boil hard 4 minutes, then add the stock.
Sit the celeriac in a deep casserole, pour the onions and liquid around them so it comes halfway up, and cover very tightly — a lid, and foil under the lid if it is not a good fit. Six hours of steam escaping will leave you with a dry pot at hour four.
Bake 6 hours. Check at 4 hours: if the liquid has dropped below a third of the way up, add a scant 1 cup of water. It is done when a skewer goes into the center with absolutely no resistance and comes out hot, the skin has wrinkled and gone deep brown, and the flesh at the pierced points looks glassy rather than white.
Lift them out and rest 20 minutes. Peel the skin off with your fingers and a small knife — it comes away in sheets — and discard it with the salt still on it.
Strain the liquor. Soak the torn bread in ⅔ cup of it for 5 minutes until sodden, then blitz it back into the rest with a stick blender. It thickens to the body of heavy cream in seconds. Add the vinegar, taste, and salt it properly — a vegetable sauce needs more salt than a meat one and this is where most vegan mains quietly fail.
Put the peeled celeriac back into a serving pot, pour the sauce around them, take them to the table whole, and pull them apart there with two forks. They come away in dense strands.

Make-ahead

Bake the day before, cool within two hours, and keep the peeled celeriac sitting in the strained liquor in the fridge. Like the braise it stands beside, it is arguably better on day two. Make the sauce fresh on the night; blitzed bread thickener continues to set overnight and goes pasty.

Reheat covered in its liquor for 50 minutes at 300°F, until hot all the way through. If you are cooking both this and the lamb, they reheat together on the same shelf at the same temperature, which is not a coincidence.

Holding and service

Serve at about 140°F, matching the lamb, which is warm rather than scalding and is what the repaired vessels at this dinner want. Covered, it holds for an hour on the table without deteriorating; celeriac holds better than meat because it has no muscle fiber to tighten.

At hour two the exposed strands have dried and darkened at the edges, which looks appetising rather than sad. It can be plated in advance if you must, but do not — the arrival of a whole dark object in a pot is doing half the work of making this the same event as the meat, and a pre-shredded bowl is not the same event.

One service note that matters more than it sounds. Put it on the table at the same moment as the lamb, in the same style of pot, and let the people eating it serve themselves first. A vegan main that arrives ninety seconds later, carried separately, from a different direction, tells the whole table something.

Scaling

Everything multiplies straight except the liquid, which follows the pot rather than the quantity: a crowded casserole needs proportionally less because there is less surface to evaporate from. Keep the level halfway up the vegetables whatever you are cooking.

Time does not scale with number but it does scale with size, so buy celeriac of similar weight and cook to the skewer. A 3¼ lb celeriac wants closer to 7 hours. What does not scale at all is oven space when this is sharing an oven with a braise and a tray of cabbage; at more than about 30 covers, bake the celeriac the day before and free the oven entirely.

Substitutions

Whole pointed or sweetheart cabbage: same braise, 2 hours instead of 6, halved rather than whole. Sweeter, softer, and it pulls apart in leaves rather than strands. A genuinely good dish and a visibly different one.
Whole rutabaga or a large kohlrabi: 5 hours. Rutabaga is sweeter and more assertive and wants an extra tablespoon of vinegar at the end.
Gluten-free: ½ cup buckwheat groats, toasted dry until they smell nutty, simmered 15 minutes in the liquor and blitzed. Same body, nuttier. This version is both vegan and gluten-free, which makes it the single most useful pot on the table.

Why it belongs at this dinner

This is the vegetarian and vegan main for The Gold Is in the Cracks, Tangled Thistle’s Occasion Study No. 26 — a dinner served on ceramics that broke and were repaired. That study’s whole discipline is that nobody at the table is made to feel like an exception, and a menu obeys the same rule or it does not obey it at all. Same pot, same minute, same gesture, same sauce, same name of its own. It stands beside the lamb shoulder, and the full design is Nothing Here Soaks Overnight.
