Irish Stew Recipe: A Hearty Lamb and Potato Supper

Irish stew is a slow-simmered Irish dish of tender lamb, potatoes, and onion in a savory broth; carrots appear in many modern and family versions. Gentle cooking lets the lamb become tender while the potatoes lend the broth body, making this a satisfying one-pot supper with straightforward ingredients.

Ingredients

2 lb (900 g) boneless lamb shoulder, trimmed of excess fat and cut into 1½-inch (4 cm) chunks
1½ tsp (9 g) fine salt, divided, plus more to taste
½ tsp (1 g) freshly ground black pepper
1 tbsp (15 ml) neutral oil, such as canola oil
2 medium yellow onions (about 10 oz / 300 g), peeled and cut into wedges
5 cups (1.2 L) low-sodium lamb or beef stock
1 tsp (1 g) dried thyme, or 1 tbsp (4 g) fresh thyme leaves
2 bay leaves
1½ lb (680 g) Yukon Gold or other waxy potatoes, scrubbed and cut into 1½-inch (4 cm) chunks
3 medium carrots (about 10 oz / 300 g), peeled if desired and cut into 1-inch (2.5 cm) pieces
2 tbsp (8 g) chopped fresh parsley, for serving

Instructions

Prepare the ingredients. Pat the lamb dry with paper towels so it browns more readily. Season it with about 1 teaspoon of the salt and the pepper. Cut the onions, potatoes, and carrots as directed, keeping the potato pieces fairly even so they finish cooking together. Set a large, heavy Dutch oven or other lidded pot nearby.
Brown the lamb. Heat the oil in the pot over medium-high heat. Working in two batches so the pieces have room, brown the lamb on two or three sides, about 6 minutes per batch. Transfer the browned pieces to a plate. Browning builds a deeper, meatier flavor, but avoid letting the pan smoke; lower the heat if the fond on the bottom becomes very dark.
Start the broth. Add the onion wedges to the pot and cook for about 3 minutes, stirring and scraping up the browned bits. Return the lamb and any juices to the pot. Pour in the stock, then add the thyme, bay leaves, and remaining ½ teaspoon salt. The liquid should come close to covering the lamb. If it does not, add a little water; the stew does not need to be completely submerged.
Simmer the lamb. Bring the liquid just to a simmer, then reduce the heat to low. Cover the pot and cook gently for 1 hour 10 minutes. Look for small, occasional bubbles rather than a rolling boil, which can make the meat tough and break up the onions. Stir once or twice, scraping the bottom, and adjust the heat as needed. Keep the lid on between checks so the liquid does not reduce too quickly.
Add the vegetables. Stir in the potatoes and carrots, then cover and simmer gently for 30 minutes, or until the potatoes are tender when pierced and the lamb is easy to cut with a spoon. Check a thick piece of lamb with a food thermometer: USDA FSIS lists 145°F (63°C) with a 3-minute rest as the safe minimum for whole cuts of lamb; this braised stew cooks the meat well beyond that temperature for tenderness. If the vegetables need a few more minutes, continue simmering and check them again.
Finish and serve. Turn off the heat and let the stew stand, covered, for 10 minutes. Remove the bay leaves. Taste the broth and add salt or pepper if needed. For a slightly thicker texture, gently press a few potato pieces against the side of the pot and stir them into the broth. Sprinkle with parsley and serve hot.

Tips

Choose a braising cut. Lamb shoulder has enough connective tissue to turn tender during a long, gentle simmer. Lean leg meat can be used, but it is easier to overcook and may not make the broth as rich. Ask a butcher to cut shoulder into stew-size pieces if that is convenient.
Keep the simmer calm. A vigorous boil can make meat fibers tighten and potatoes crumble before the lamb is tender. If the surface is bubbling rapidly, turn the heat down. A heavy pot helps hold a steady temperature.
Pick potatoes that hold their shape. Yukon Gold or another waxy potato gives the stew a creamy texture while staying in chunks. Floury russet potatoes are also usable, but they break down more readily and will thicken the broth more. Cut them a little larger and handle the pot gently.
Adjust thickness without flour. Irish stew can be brothy or hearty, depending on the household. If yours seems thin, mash a few cooked potatoes into the liquid. If it has reduced too far, stir in hot water or stock a little at a time. Low-sodium stock makes it easier to season accurately at the end.

Serving Suggestions

Serve Irish stew in warm bowls with a spoon so everyone can enjoy the broth as well as the lamb and vegetables. Chopped parsley adds a fresh finish, and a slice of sturdy brown bread or soda bread is useful for soaking up the last of the liquid. If you prefer a fuller meal, offer a simple green salad or steamed cabbage alongside it; choose a lightly dressed side so it does not compete with the stew.

This recipe is substantial enough to serve on its own, but portion sizes can vary with the occasion. For a smaller first course, serve modest bowls before a lighter main dish. For a casual supper, put the pot on the table with bread and let people serve themselves. A little freshly ground black pepper at the table is an easy finishing touch.

Variations

Irish stew has family and regional variations, so there is no single version that every cook follows. Older, spare versions commonly center on mutton or lamb, potatoes, and onions. Carrots are a familiar addition in many contemporary recipes, as they are here, but you can leave them out for a simpler, more traditional-style combination. Mutton is harder to find than lamb in many shops; lamb shoulder is a practical substitute with a milder flavor.

For a richer broth, replace up to 1 cup (240 ml) of the stock with water and add a lamb bone to the pot if you have one. Remove the bone before serving. For a lighter-tasting version, use beef stock or chicken stock, though either will change the character of the broth. Vegetable stock can work too, but the stew will have less of the savory depth supplied by lamb stock.

You can add a small turnip or rutabaga, cut into chunks, with the carrots and potatoes. This gives the stew an earthy sweetness and makes it more vegetable-forward; keep the total amount of vegetables close to the recipe quantity so the pot does not become crowded. For a gluten-free stew, the recipe as written needs no flour or other wheat-based thickener. If you like a more rustic texture, mash a few potatoes into the broth after cooking rather than adding a separate thickener.

Storage and Reheating

Refrigerate leftover stew within 2 hours of cooking, in shallow, covered containers. It keeps for 3 to 4 days in the refrigerator. The broth may thicken as it chills, and some fat may set on the surface; both are normal. Lift off excess solidified fat if you prefer, then stir the stew before reheating. Potatoes soften a little more after storage, so handle the leftovers gently.

Reheat only the portion you plan to eat in a saucepan over medium-low heat, stirring occasionally, until it is steaming throughout and reaches 165°F (74°C). Add a splash of water or stock if the broth has become too thick. You can also reheat a serving in a microwave-safe bowl, covered loosely, stirring partway through; check several spots with a food thermometer to confirm it reaches 165°F (74°C). Cool and refrigerate any remaining stew promptly rather than leaving it at room temperature.

For longer storage, freeze cooled stew in airtight freezer-safe containers for up to 3 months for best quality. Leave a little space at the top for expansion. Thaw it overnight in the refrigerator, then reheat to 165°F (74°C). The potatoes may be softer after freezing and thawing, but the stew will still be suitable to serve.

Frequently Asked Questions

Can I make Irish stew with beef instead of lamb?
Yes. Use beef chuck cut into 1½-inch (4 cm) chunks in the same quantity. It needs a similar gentle braise, though the exact time can vary with the cut and size of the pieces. Cook until tender, and check that whole-cut beef reaches the USDA FSIS safe minimum of 145°F (63°C) with a 3-minute rest; a stew cooked until tender will usually go well beyond that.

Do I have to brown the lamb?
No, but browning adds roasted, savory notes that make the finished broth taste fuller. If you skip it, bring the stock, onions, seasonings, and lamb to a gentle simmer and continue with the covered braise. Do not compensate by turning up the heat; a calm simmer is more important for tender lamb.

Why are my potatoes falling apart?
They may be a floury variety, cut too small, or cooked for longer than needed. Use evenly cut waxy potatoes, add them only for the final 30 minutes, and avoid stirring vigorously. If a few edges break down, that naturally thickens the broth; if you want distinct chunks, stop cooking as soon as a knife passes through easily.

Can I prepare Irish stew a day ahead?
Yes. Cool it promptly in shallow containers and refrigerate within 2 hours. The flavors settle as it rests, and it reheats well the next day. Warm it gently on the stove, adding a little water or stock if necessary, and bring it to 165°F (74°C) before serving. The potatoes will be softer than when freshly cooked.

What can I use if I cannot find lamb stock?
Low-sodium beef stock is the closest easy substitute and gives the broth a deep, savory taste. Chicken stock makes a lighter broth, while vegetable stock keeps the dish less meat-forward. If using a salty stock, reduce the added salt at the beginning and adjust it after the stew has finished cooking.
