Irish Stew Recipe with Lamb, Potatoes, and Carrots

Irish stew is a hearty Irish dish of tender lamb, potatoes, onions, and carrots simmered in a savory broth. This version browns lamb shoulder for a deeper flavor, then cooks it slowly with the vegetables until everything is fork-tender; family and regional versions vary, and some use mutton or keep the ingredient list simpler.

Ingredients

2 lb (900 g) boneless lamb shoulder, trimmed and cut into 1 1/2-inch (4 cm) pieces
1 1/2 tsp (9 g) fine salt, divided, plus more to taste
1/2 tsp (1 g) black pepper
1 tbsp (15 ml) neutral oil, such as canola oil
2 medium yellow onions, about 10 oz (280 g), peeled and cut into wedges
2 tbsp (16 g) all-purpose flour
4 cups (950 ml) low-sodium lamb or beef stock
3 medium carrots, about 10 oz (280 g), peeled and cut into 1-inch (2.5 cm) pieces
2 lb (900 g) Yukon Gold or other waxy potatoes, scrubbed and cut into 1 1/2-inch (4 cm) chunks
2 dried bay leaves
1 tsp (1 g) dried thyme, or 1 tbsp (3 g) fresh thyme leaves
2 tbsp (8 g) chopped fresh parsley, plus extra for serving
1 tsp (5 ml) Worcestershire sauce, optional

Instructions

Prepare the lamb and vegetables. Pat the lamb dry with paper towels; dry meat browns more readily than damp meat. Season it with 1 tsp (6 g) of the salt and the pepper. Cut the onions, carrots, and potatoes into the sizes listed so they cook at a similar pace. Keep the potato pieces fairly large: small dice can break down during the long simmer and make the broth overly starchy.
Brown the lamb. Set a large, heavy Dutch oven or stew pot over medium-high heat and add the oil. Working in two batches so the pieces have room, brown the lamb on several sides, about 4 to 5 minutes per batch. Transfer the browned pieces to a plate. They do not need to be cooked through at this stage. If the pot becomes dry, add a small splash of water rather than extra oil; scrape up browned bits as the liquid loosens them.
Soften the onions and coat the meat. Reduce the heat to medium, add the onions, and cook for about 5 minutes, stirring occasionally, until they begin to soften. Sprinkle in the flour and stir for 1 minute so it does not taste raw. Return the lamb and any juices on the plate to the pot. The flour gives the broth a light body; it should not turn the stew into a thick gravy.
Start the simmer. Pour in the stock and stir, scraping the bottom of the pot. Add the bay leaves, thyme, Worcestershire sauce if using, and the remaining 1/2 tsp (3 g) salt. Bring the liquid just to a gentle simmer, then lower the heat. Cover with the lid slightly ajar and simmer gently for 1 hour and 5 minutes. Avoid a hard boil, which can toughen the lamb and break up the vegetables later.
Add the carrots and potatoes. Stir in the carrots and potatoes, making sure they are mostly nestled in the liquid. Cover again and simmer gently for 27 minutes, or until the potatoes are tender when pierced with a small knife and the lamb is fork-tender. Check once or twice that the bottom is not sticking; add a little hot water or stock if the liquid has reduced more than you like. For food safety, USDA FSIS gives whole cuts of lamb a safe minimum internal temperature of 145°F (63°C) with a 3-minute rest; check a large piece with a food thermometer and let the stew stand off the heat for 3 minutes before serving. The longer simmer should make shoulder tender as well as safely cooked.
Finish and taste. Remove the bay leaves. Stir in the parsley, then taste the broth and add more salt or pepper if needed. If you prefer a slightly thicker broth, mash one or two potato pieces against the side of the pot and stir them in. Let the stew rest for 3 minutes before ladling it into warm bowls.

Tips

Choose shoulder for tenderness. Lamb shoulder has enough connective tissue to become tender during a slow simmer. Boneless stew meat can work, but pieces may come from different cuts and finish at different times, so start checking for tenderness when the vegetables are nearly done. Mutton is a traditional option in some versions and has a stronger, more pronounced flavor; it may need a longer simmer.
Brown in batches. Crowding the pot makes meat release moisture and steam instead of browning. Give the pieces space, and take an extra few minutes for a second batch if necessary. Browning is a flavor-building step, not a way to cook the lamb through.
Keep the simmer gentle. Small, occasional bubbles are enough. A rolling boil can make meat fibers firm and cause potatoes to crumble. If your stove runs hot, use a heat diffuser or move the pot to a smaller burner.
Adjust the broth thoughtfully. Stock varies in saltiness, so use low-sodium stock and season near the end. If you need a gluten-free stew, leave out the flour; the broth will be lighter, and you can mash a little potato into it. For a stronger traditional flavor, use mutton if available, or lamb stock; beef stock is a practical substitute and gives a slightly deeper, less lamb-forward broth.

Serving Suggestions

Serve Irish stew hot in deep bowls, with chopped parsley scattered over the top. A slice of crusty bread or brown soda bread is useful for soaking up the broth. If you want a fuller table, add a simple green salad dressed with vinegar or a side of steamed cabbage; both bring freshness without competing with the stew. The recipe is substantial enough to serve on its own, especially when the bowls include a generous mix of lamb, potatoes, and carrots.

For a relaxed meal, put the pot on the table with extra black pepper and bread alongside it. If serving guests, warm the bowls first so the stew stays hot longer. The broth should be spoonable rather than gravy-thick; if it seems too concentrated after resting, loosen it with a splash of hot stock or water and taste again before serving.

Variations

More traditional and simple: Skip the flour, Worcestershire sauce, and browning. Layer lamb or mutton with potatoes and onions, add stock or water, and simmer gently until tender. This produces a paler, cleaner-tasting broth and reflects the simpler ingredient lists found in many home-style versions. Add carrots if you like; their place in Irish stew varies by household and recipe.

Use beef or another lamb cut: Beef chuck can replace the lamb in the same amount and is a practical choice when lamb is unavailable, though the result will taste more like beef stew. If using lamb leg, trim excess surface fat and begin checking earlier, since it is leaner than shoulder and can become dry if cooked far beyond tenderness.

Add another root vegetable: Replace up to 8 oz (225 g) of the potatoes with peeled parsnip or turnip, cut into chunks. Parsnip adds sweetness, while turnip brings a mild earthy flavor. Add either with the carrots and potatoes, and cut the pieces to roughly the same size so they soften evenly.

Make it gluten-free: Omit the all-purpose flour and use stock labeled gluten-free. The broth will be thinner, but mashing a few cooked potato pieces into it adds body without a separate thickener. Check the label on Worcestershire sauce too, or leave it out.

Storage and Reheating

Refrigerate leftover stew within 2 hours of cooking, in shallow airtight containers so it cools promptly. Keep it refrigerated for 3 to 4 days. The potatoes may absorb some broth as the stew sits, so stir in a little water or stock when reheating. For longer storage, freeze portions in freezer-safe containers for up to 3 months for best quality; leave a little room for expansion and thaw overnight in the refrigerator.

Reheat only the portion you plan to eat, either in a covered saucepan over medium-low heat or in the microwave, stirring occasionally so it heats evenly. Add a splash of water or stock if it has thickened. USDA FSIS recommends reheating leftovers to 165°F (74°C); check the center with a food thermometer. Do not leave the stew at room temperature for more than 2 hours, or more than 1 hour when the room is above 90°F (32°C).

Frequently Asked Questions

What cut of lamb is best for Irish stew?
Boneless lamb shoulder is a dependable choice because its connective tissue softens during a long, gentle simmer. Lamb stew meat also works, but the cut and size may vary. Mutton is used in some traditional versions and tastes more robust; allow extra time if it is not tender by the end of the stated simmer.

Should I peel the potatoes?
Peeling is optional with thin-skinned Yukon Gold potatoes. Scrub them well and leave the skins on for a more rustic bowl, or peel them if you prefer a smoother texture. Avoid very small potato pieces either way, since they are more likely to fall apart before the lamb is tender.

Can I make Irish stew ahead?
Yes. Cook it fully, cool it promptly in shallow containers, and refrigerate it within 2 hours. It keeps for 3 to 4 days refrigerated. Reheat gently until the center reaches 165°F (74°C), adding a little stock if the potatoes have absorbed too much broth. The flavor often seems more blended the next day, though the potatoes may be softer.

Why is my lamb still tough?
It usually needs more time at a gentle simmer. Shoulder can take longer depending on the size of the pieces and how steady the heat is. Keep the pot covered, check that it is barely bubbling, and continue cooking in 10-minute increments until a fork slips into the lamb easily. Do not turn up the heat to rush it.

Can I cook this in a slow cooker?
Yes. Brown the lamb and soften the onions in a skillet first for better flavor, then transfer them to the slow cooker with the stock, herbs, carrots, and potatoes. Cook on low until the lamb is tender, generally about 7 to 8 hours, or on high for about 4 to 5 hours; slow cookers vary, so check doneness rather than relying only on the clock. If you want a thicker broth, stir in a flour slurry near the end or mash a potato into the liquid.

Is Irish stew supposed to be thick?
It is usually a brothy stew rather than a thick gravy, although recipes differ. This recipe uses a small amount of flour for light body. For a clearer broth, omit it; for a thicker bowl, mash a few cooked potatoes into the liquid instead of adding a large amount of flour.
