Irish stew is a slow-simmered dish of lamb, potatoes, onions, and herbs, traditionally associated with Ireland and served hot as a hearty one-pot meal. Family and regional versions vary: some keep the ingredients spare, while others add carrots or use different cuts of lamb; this version uses thyme, bay, and parsley for a fragrant, balanced broth.
Ingredients
- 2 lb (900 g) boneless lamb shoulder, cut into 1½-inch (4 cm) pieces
- 1 tbsp (15 ml) neutral oil, such as canola oil
- 2 medium yellow onions, about 10 oz (300 g), peeled and cut into wedges
- 2 garlic cloves, about 6 g, finely chopped
- 3 medium carrots, about 10 oz (300 g), peeled and cut into 1-inch (2.5 cm) pieces
- 2 celery stalks, about 4 oz (115 g), cut into ½-inch (1 cm) slices
- 1½ lb (680 g) waxy potatoes, such as Yukon Gold, cut into 1½-inch (4 cm) chunks
- 5 cups (1.2 L) low-sodium lamb or chicken stock, or water for a milder, more traditional-style broth
- 1 tbsp (3 g) fresh thyme leaves, or 1 tsp (1 g) dried thyme
- 2 dried bay leaves, about 0.2 g
- 1 tsp (6 g) fine salt, plus more to taste
- ½ tsp (1 g) freshly ground black pepper, plus more to taste
- ¼ cup (15 g) chopped fresh flat-leaf parsley, divided
Instructions
- Prepare the ingredients. Pat the lamb dry with paper towels so it browns rather than steams. Cut the vegetables into pieces of similar size, keeping the potatoes fairly large so they hold their shape during simmering. Measure out the stock, thyme, bay leaves, salt, and pepper before you start cooking. If the lamb is sold in larger pieces, trim away thick, hard pieces of surface fat, but leave a little marbling for flavor.
- Brown the lamb in batches. Set a heavy 5- to 6-quart Dutch oven or similar pot over medium-high heat and add the oil. When it shimmers, add enough lamb to cover the bottom without crowding. Brown the pieces for about 2 minutes per side, turning with tongs; transfer them to a plate and repeat with the remaining lamb. Work in batches rather than piling the meat in, since crowded pieces release moisture and will not develop as much color. If the pot becomes dry, add a small splash of oil.
- Soften the onions and garlic. Lower the heat to medium. Add the onion wedges to the same pot and cook for about 3 minutes, stirring and scraping up browned bits. Add the garlic and cook for 30 seconds, just until fragrant. Do not let the garlic darken, which can make the broth taste bitter. The onions will continue to soften as the stew simmers.
- Start the lamb simmer. Return the lamb and any juices from the plate to the pot. Pour in the stock or water, then add the thyme, bay leaves, salt, and pepper. The liquid should come close to covering the meat; add up to ½ cup (120 ml) extra water if needed. Bring the pot just to a boil, then immediately reduce the heat to low. Cover with the lid slightly ajar and simmer gently for 60 minutes. A few small bubbles should rise now and then; a hard boil can toughen the lamb and break up the vegetables later.
- Add the vegetables. Stir in the carrots, celery, and potatoes, nestling the potatoes into the liquid. Cover the pot slightly ajar again and simmer for 25 minutes, or until the potatoes are tender when pierced with a small knife and the lamb yields easily when pressed with a fork. Check that the largest lamb pieces have reached the USDA FSIS safe minimum internal temperature of 145°F (63°C), measured with a food thermometer, and rest them for at least 3 minutes. The long simmer should make the lamb tender as well as safely cooked.
- Adjust the broth and seasoning. Remove and discard the bay leaves. If the broth seems thinner than you like, simmer the stew uncovered for 5 to 10 minutes, taking care not to let the potatoes collapse. For a slightly thicker texture, gently press one or two potato pieces against the side of the pot and stir them into the broth. Taste and add salt or pepper a little at a time. Stir in half of the parsley and let the stew stand off the heat for 5 minutes so the broth settles.
- Finish and serve. Ladle the stew into warm bowls, making sure each serving gets a mix of lamb, potatoes, and vegetables. Scatter the remaining parsley over the top. Serve while hot, with bread on the side for the broth.
Tips
- Choose a cut suited to a long simmer. Lamb shoulder is well marbled and becomes tender as it cooks. Lamb neck or stewing lamb also works, though bone-in pieces may need extra room in the pot and can take longer to become tender. Lean leg meat is less forgiving and may turn dry if simmered for as long.
- Keep the simmer gentle. After bringing the liquid to a boil, lower the heat until it barely bubbles. If the surface is boiling vigorously, reduce the heat. A gentle simmer helps the lamb soften while keeping the potatoes and carrots intact.
- Use water or stock according to the flavor you want. Water gives a clean, light broth and is a useful traditional-style option; low-sodium stock creates a fuller savory flavor. If using regular salted stock, start with less added salt and adjust at the end.
- Be cautious when stirring. Potatoes can break down if stirred vigorously, especially near the end. Use a broad spoon to lift from the bottom, and avoid repeatedly checking or stirring once the vegetables are tender.
Serving Suggestions
Serve Irish stew in deep bowls so the broth stays hot and each portion can include a generous share of lamb and vegetables. A slice of sturdy brown bread, soda bread, or crusty bread is useful for soaking up the broth. If you want something fresh alongside it, offer a simple green salad dressed with vinegar or lemon; its crispness contrasts with the soft, savory stew without competing with the herbs.
For a fuller table, serve the stew with steamed cabbage or lightly cooked greens. Keep any side dish simply seasoned, since the stew already has a substantial mix of meat, potatoes, and root vegetables. Extra chopped parsley can be set out for diners to add at the table, and black pepper is a welcome finishing touch. The stew is filling on its own, so small portions of sides are usually enough.
Variations
Keep it spare and traditional in spirit: Leave out the celery and carrots, and use water instead of stock. The result is less sweet and more focused on lamb, onion, potato, and herbs. There are many household versions of Irish stew, so neither this vegetable-rich approach nor the simpler one represents the only correct version.
Use mutton or bone-in lamb: Mutton has a more pronounced flavor and may need additional simmering to become tender. Bone-in shoulder or neck adds depth to the broth, but allow extra time if the pieces are large and remove any loose bones before serving. Check tenderness rather than relying only on the clock.
Change the herb profile: Thyme and bay give a familiar savory backbone. You can replace up to half the thyme with 1 tsp (1 g) chopped fresh rosemary, but rosemary has a stronger, resinous flavor, so use it sparingly. Parsley is best added near the end; long cooking dulls its fresh taste.
Make it without lamb: For a meat-free variation, replace the lamb with 1 lb (450 g) sliced mushrooms and 1½ cups (250 g) cooked white beans, and use vegetable stock. Brown the mushrooms well, then simmer the vegetables for about 25 minutes, adding the beans for the final 10 minutes. This changes the dish substantially, but keeps the potato-and-herb stew character.
Storage and Reheating
Refrigerate leftover stew within 2 hours of cooking, divided into shallow, covered containers so it cools promptly. It keeps for 3 to 4 days in the refrigerator. The potatoes may soften and absorb some broth as it sits, so the stew can be thicker the next day; stir in a little water or stock when reheating if needed.
Reheat only the amount you plan to eat in a saucepan over medium-low heat, stirring gently until it is steaming throughout and reaches 165°F (74°C), the USDA FSIS safe temperature for leftovers. You can also microwave a covered portion, stirring partway through and checking the center with a food thermometer. Avoid repeatedly cooling and reheating the full pot.
For longer storage, freeze cooled portions in freezer-safe containers, leaving a little headspace for expansion. The stew is best used within 2 to 3 months for quality. Thaw it overnight in the refrigerator, then reheat to 165°F (74°C); potatoes may be softer after freezing, but the broth and lamb will still make a satisfying meal.
Frequently Asked Questions
Can I make Irish stew ahead of time?
Yes. Cook it through, cool it promptly, and refrigerate it for up to 3 to 4 days. The flavor often becomes more settled after a night in the refrigerator. Reheat gently to 165°F (74°C), adding a splash of water or stock if the potatoes have thickened the broth.
Why is my lamb still tough?
Lamb shoulder needs time for its connective tissue to soften. Keep the pot at a gentle simmer and continue cooking in 10- to 15-minute increments until the pieces yield easily to a fork. A vigorous boil can make meat seem tight, while large or older pieces may simply need longer than the recipe estimate.
Can I make this in a slow cooker?
Yes. Brown the lamb and soften the onions on the stove first for better flavor, then transfer them to the slow cooker with the stock, herbs, and vegetables. Cook on low until the lamb and potatoes are tender, generally about 7 to 8 hours, but follow your appliance’s guidance and check early enough to prevent the vegetables from becoming mushy. Verify the lamb’s safe temperature with a food thermometer.
Which potatoes are best for stew?
Waxy or all-purpose potatoes, including Yukon Gold, hold their shape better than very floury varieties. Cut them into generous chunks and add them for the final 25 minutes in this stovetop method. If you prefer a thicker broth, a flourier potato can help, but it is more likely to break apart.
Can I thicken the broth without flour?
Yes. Simmer uncovered briefly to evaporate some liquid, or mash one or two cooked potato pieces into the broth. Both options thicken the stew without adding flour. Make changes gradually: the broth also thickens as it cools and as the potatoes release starch.
