Wales's national stew — slow-simmered Welsh lamb shoulder, swede, carrots, potatoes and a final shower of fresh leeks, served the day after for the deepest flavour.
Cawl (pronounced cowl) is the national dish of Wales, a stew so deeply woven into the fabric of Welsh rural life that the word simply means 'soup' in Welsh. Every Welsh family has a version, but the bones are always the same: a piece of Welsh lamb (shoulder or neck, ideally on the bone), the holy trinity of the Welsh winter garden — swede, carrots, and potatoes — and the indispensable garnish of fresh chopped leek, the national vegetable, stirred in raw at the very end so it stays sweet and bright against the long-cooked broth. The whole point of cawl is patience: the lamb is simmered for hours with the harder root vegetables to build a rich golden stock, then the cawl is rested overnight in a cool place so the fat rises and can be skimmed, the flavours deepen, and the meat surrenders. It is reheated the next day, the freshly chopped leeks added at the last minute, and served in deep bowls with a wedge of mature Caerphilly cheese on a separate plate. Traditionally each diner spoons broth and vegetables, eats the broth first as a starter, then has the meat and remaining vegetables as the main with the cheese melted on top. It is the dish of St David's Day on 1st March, of cold farmhouse kitchens, and of any household where keeping the body warm through a Welsh winter matters more than fashion.
Serves 6
Place the lamb pieces in a large heavy pot. Cover with the cold water and bring slowly to a simmer over medium heat — do not boil aggressively. Skim off any grey foam that rises to the surface using a slotted spoon for the first 10 minutes.
Once skimmed, add the onion wedges, carrot chunks, swede chunks, bay leaves, salt and pepper. Return to a gentle simmer, cover partially, and cook over low heat for 90 minutes, until the lamb is meltingly tender and pulling from the bone.
Tip in the potato chunks and simmer uncovered for a further 25 minutes until the potatoes are tender. The broth should have reduced and intensified into a deep golden stock at this point.
Take the pot off the heat, cool to room temperature, then refrigerate covered overnight. This step is non-negotiable for true cawl — the resting transforms the dish and lets the lamb fat rise to the top for skimming.
Skipping this step gives you lamb soup; honouring it gives you cawl.
Lift the solid layer of lamb fat off the top of the cold cawl with a spoon and discard (or save for roast potatoes). Set the pot over medium heat and bring back to a gentle simmer. Taste and adjust seasoning — the chilling will have flattened the salt slightly.
Once the cawl is steaming hot, scatter in the chopped raw leeks and parsley. Cook only 3–4 minutes — the leeks should soften but stay bright green and sweet, never going grey or mushy. Pull off the heat.
Ladle into deep warm bowls, ensuring everyone gets broth, lamb, and a generous helping of each vegetable. Serve with hunks of crumbly Caerphilly cheese on a separate plate and crusty bread. Some Welsh households serve the broth first and the meat-and-vegetables second from the same bowl.
Lamb on the bone is essential — the bone makes the stock. Boneless lamb gives a thin, characterless broth.
Resting overnight is what separates cawl from any other lamb soup. Do not skip this step.
Add the leeks raw at the end. Cooking them with the rest of the stew dulls their flavour and turns them sad and grey.
Welsh lamb has a distinctive flavour — if you can find PGI Welsh Lamb, use it. Otherwise any pasture-raised lamb shoulder works well.
Bacon cawl — add 200 g of Welsh smoked bacon at the start for a richer, smokier version popular in the south Wales valleys.
Mutton cawl — the original made with older sheep meat; richer and gamier, cook for an extra hour.
Vegetable cawl — the meat-free version with extra root vegetables, pearl barley, and a strong vegetable stock; eaten through the year not just Lent.
Cawl Mam Iesu (Jesus's mother's cawl) — a Saint David's Day variation with extra leeks for symbolism.
Refrigerate up to 4 days, deepening in flavour every day. Freezes 3 months in portion containers — defrost overnight and reheat gently, adding the fresh leeks only at the final moment. The traditional Welsh practice is to make a huge pot and eat it for three or four meals running.
Cawl has been the staple of Welsh rural cookery for at least eight centuries, mentioned in medieval Welsh poetry as the food of farmers and shepherds. It became the unofficial national dish in the 19th century when Welsh-language pride emerged, and is now formally served at Saint David's Day celebrations on 1st March worldwide.
The overnight rest does three things: it lets the fat solidify so you can remove it cleanly, it allows flavours to meld and deepen, and it makes the lamb more tender as the connective tissue continues to relax. Cawl eaten on day one is just lamb stew; cawl eaten on day two is cawl.
A mild, crumbly, slightly tangy Welsh cheese traditionally made in Caerphilly, south Wales. It is the only cheese authentic to cawl. If unavailable, a mild Lancashire or a young Wensleydale works.
Leg is too lean and goes stringy in the long cook. Shoulder or neck have the connective tissue that breaks down into silky tenderness over the long simmer.
Cawl is the Welsh word for soup or broth generally — but capital-C Cawl now specifically refers to this lamb and root vegetable stew, the national dish.
