Healthy Welsh Cawl with Lamb, Leeks, and Vegetables

Welsh cawl is a comforting broth-stew traditionally made with lamb or beef, potatoes, leeks, and seasonal vegetables; recipes vary by region and household. This vegetable-forward version uses tender lamb shoulder and a clear, savory broth, so each bowl is hearty without relying on cream or a thickened sauce.

Ingredients

1 tablespoon olive oil (15 ml)
1¼ pounds boneless lamb shoulder, trimmed and cut into 1-inch cubes (570 g)
1 medium yellow onion, finely chopped, about 1 cup (150 g)
2 garlic cloves, minced, about 2 teaspoons (6 g)
8 cups low-sodium lamb or chicken stock (1.9 L); water can be used, though the broth will taste milder
2 bay leaves
1 teaspoon dried thyme (1 g), or 3 fresh thyme sprigs
½ teaspoon freshly ground black pepper (1 g)
1 teaspoon kosher salt (5 g), plus more to taste
3 medium carrots, peeled and cut into ½-inch pieces, about 2 cups (260 g)
1 medium parsnip, peeled and cut into ½-inch pieces, about 1 cup (150 g)
1 pound waxy potatoes, such as Yukon Gold, scrubbed and cut into 1-inch pieces, about 3 cups (450 g)
2 medium leeks, white and light-green parts sliced and thoroughly rinsed, about 2½ cups (300 g)
3 cups thinly sliced green cabbage (210 g)
2 tablespoons chopped fresh parsley (8 g), for serving

Instructions

Prepare the ingredients. Trim excess hard fat from the lamb, cut it into evenly sized cubes, and pat the pieces dry with paper towels. Chop the onion and garlic, prepare the root vegetables and potatoes, and slice and rinse the leeks. Leeks often hold grit between their layers: separate the slices in a bowl of cold water, swish them around, then lift them out so the grit stays behind. Drain the cabbage and set the vegetables aside in groups according to when they go into the pot.
Brown the lamb and aromatics. Heat the olive oil in a large, heavy pot or Dutch oven over medium-high heat. Add the lamb in a single layer, working in batches if needed, and brown it for about 7 minutes, turning the pieces so several sides develop color. Avoid crowding the pot, which makes the meat steam instead of brown. Add the onion and cook for 2 minutes, stirring; add the garlic and stir for about 30 seconds. If the bottom looks very dry, add a splash of stock rather than extra oil.
Build the broth and simmer. Pour in the stock and scrape the browned bits from the bottom of the pot. Add the bay leaves, thyme, pepper, and measured salt. Bring the liquid just to a boil, then lower the heat until it maintains a gentle simmer. Cover with the lid slightly ajar and cook for 75 minutes, stirring once or twice. A quiet simmer keeps the lamb moist and the broth clear; a hard boil can make the meat tighten and break the vegetables later. If foam gathers at the top early on, skim it away with a spoon.
Add the sturdy vegetables. Stir in the carrots, parsnip, and potatoes. Bring the pot back to a gentle simmer, cover it slightly ajar again, and cook for 20 minutes. Check a potato and a piece of carrot with a fork: they should be nearly tender but not collapsing. Cut the vegetables to similar sizes so they cook at roughly the same rate. If the liquid no longer covers most of the ingredients, add a little hot water or stock.
Finish with leeks and cabbage. Add the rinsed leeks and sliced cabbage, stir gently, and simmer uncovered for 12 minutes, or until the leeks are soft and the cabbage is tender but still holds its shape. Taste the broth and adjust the salt and pepper. The cabbage and leeks release moisture as they cook, so taste before adding extra salt. Remove the bay leaves and thyme stems if using fresh thyme.
Check the lamb and rest the pot. Check the center of the largest lamb piece with a food thermometer. For whole cuts of lamb, the USDA FSIS safe minimum is 145°F (63°C), followed by a 3-minute rest; the longer simmer in this stew should take the meat well beyond that minimum and make it tender. Turn off the heat and let the cawl stand for 3 minutes before serving. Sprinkle with parsley at the table.

Tips

Choose shoulder for tenderness. Boneless lamb shoulder has enough connective tissue to become tender during a long, gentle simmer. Lean leg meat can be substituted, but it may turn drier if cooked for the full time; begin checking it earlier and remove any pieces that are tender while the vegetables finish.
Clean leeks carefully. Dirt can hide inside the layers, especially near the pale green tops. Slice first, swish the pieces in a large bowl of water, and lift them out instead of pouring the bowl through a colander, which can tip grit back onto the leeks.
Keep the simmer gentle. Small bubbles around the edge are enough. If the pot boils vigorously, lower the heat and check it again after a few minutes. A steady gentle simmer helps keep the broth from turning cloudy and protects the texture of the potatoes.
Make the broth richer without thickening it. Brown the lamb in batches and scrape up the browned bits with stock. For a slightly thicker bowl, mash one or two cooked potato pieces against the side of the pot and stir them in; avoid blending the whole stew, which changes its traditional chunky texture.

Serving Suggestions

Serve cawl hot in deep bowls, making sure each portion gets lamb, potatoes, and a mix of the vegetables along with plenty of broth. Chopped parsley adds a fresh finish, and a little black pepper at the table suits the savory stock. For a familiar Welsh-style meal, offer crusty bread or oatcakes on the side to dip into the broth. A small piece of sharp cheese can be served alongside, rather than stirred into the pot, so the clean broth flavor remains distinct.

This stew can stand on its own as a filling main course, especially when the bowls contain a generous share of lamb and vegetables. If serving a group, place the pot on the table and let people choose extra broth or vegetables. Put salt, pepper, and bread out separately so each person can season their portion without over-salting the whole batch.

Variations

Use beef instead of lamb: Beef chuck cut into 1-inch cubes gives a deeper, beefier broth and works with the same sequence. Keep the simmer gentle and cook until the pieces are tender; check whole beef cuts with a thermometer for the USDA FSIS minimum of 145°F (63°C) and a 3-minute rest. Tougher stew cuts may need extra time, so add the root vegetables only when the meat is close to tender.

Make a meat-free pot: Omit the lamb and use vegetable stock, then add a drained can of cannellini beans (15 ounces/425 g) during the final 12 minutes. The beans contribute a creamy texture, but the stew will not have the same lamb-rich flavor. For more savoriness, brown sliced mushrooms with the onion and use a well-flavored vegetable stock.

Use seasonal roots: Swede, also called rutabaga, is a traditional-feeling choice in place of some of the parsnip or potato. Peel it and cut it into small cubes; it is firmer and may need the full 20 minutes with the other root vegetables. Turnips can also be used, but their sharper taste will make the broth more assertive. Keep the total amount of root vegetables close to the recipe so the pot remains brothy.

Adjust the greens: If cabbage is unavailable, use savoy cabbage or a few handfuls of chopped kale. Savoy cabbage cooks similarly; sturdy kale may need a few extra minutes to soften. Add tender greens only near the end so they keep their color and do not become limp during the long lamb simmer.

Storage and Reheating

Cool leftovers promptly and refrigerate them within 2 hours of cooking in covered, shallow containers. The cawl keeps for 3 to 4 days in the refrigerator. The potatoes will soften as they sit and absorb broth, so the leftovers may be thicker than the freshly cooked stew. Add a splash of stock or water when reheating if you want to loosen the consistency.

Reheat only the portion you plan to eat, either in a saucepan over medium-low heat or in a microwave-safe dish, stirring so it warms evenly. Reheat leftovers to 165°F (74°C), checking the center with a food thermometer. Bring stovetop portions to a gentle simmer after they reach temperature, but avoid prolonged boiling, which can break down the vegetables. Freeze cooled portions in airtight freezer containers for up to 2 to 3 months for best quality. Thaw overnight in the refrigerator and reheat to 165°F (74°C); potatoes may be softer after freezing, but the stew remains suitable for serving.

Frequently Asked Questions

Is cawl the same as Welsh lamb soup?

Cawl is a Welsh stew or broth, and lamb is a common choice, but the exact ingredients vary. Some versions use beef, different root vegetables, or cabbage depending on local and household preferences. This recipe keeps the lamb, potatoes, and leeks prominent while including carrots, parsnip, and cabbage for a full pot.

Can I make Welsh cawl without lamb?

Yes. Use vegetable stock and add beans, mushrooms, or both for substance. Add canned beans near the end so they warm through without breaking apart. The result is a meat-free vegetable stew inspired by cawl rather than a lamb version, with a lighter, less meaty broth.

Why are my leeks gritty?

Leeks grow with soil trapped between their layers, so a quick rinse of the outside may not remove it. Slice them, separate the rings in a bowl of cold water, swish well, and lift the leeks out by hand. Leave the sediment at the bottom of the bowl and repeat if you still see grit.

Can I prepare cawl a day ahead?

Yes. Cool it promptly, refrigerate it in a covered container, and reheat it the next day to 165°F (74°C). The broth may taste more integrated after resting, while the potatoes will be softer and may absorb liquid. Keep extra stock or water nearby to adjust the consistency as it reheats.

What can I use instead of parsnip?

Use an equal amount of swede (rutabaga), turnip, or extra carrot. Swede is mild and firm, while turnip has a more peppery edge and carrot tastes sweeter. Cut the substitute into pieces about the same size as the other roots so it cooks in the same 20-minute stage.
