Irish Stew and Potatoes: A Hearty One-Pot Recipe

Irish stew is a traditional Irish one-pot dish of slowly braised lamb or mutton, potatoes, and a savory broth, with carrots and other vegetables appearing in many family versions. This recipe builds flavor by browning the lamb first, then simmers it until tender before adding potatoes so they keep their shape while soaking up the broth.

Ingredients

2 lb (900 g) boneless lamb shoulder, trimmed and cut into 1½-inch (4 cm) cubes
1 tbsp (15 ml) neutral oil, such as canola oil
2 medium yellow onions, about 10 oz (300 g), peeled and chopped
2 tbsp (16 g) all-purpose flour
5 cups (1.2 L) low-sodium lamb or beef stock
2 bay leaves
1 tsp (1 g) dried thyme
1½ lb (680 g) Yukon Gold potatoes, cut into 1½-inch (4 cm) chunks
3 medium carrots, about 10 oz (300 g), peeled and cut into 1-inch (2.5 cm) pieces
2 celery ribs, about 3½ oz (100 g), sliced into ½-inch (1 cm) pieces
1¼ tsp (7 g) fine salt, plus more to taste
½ tsp (1 g) freshly ground black pepper
2 tbsp (8 g) chopped fresh parsley, for serving

Instructions

Prepare the ingredients. Pat the lamb cubes dry with paper towels; this helps them brown rather than steam. Chop the onions, carrots, celery, and potatoes as listed. Keep the potatoes in fairly even chunks so they finish cooking at the same time. Measure the stock, flour, herbs, salt, and pepper before you start.
Brown the lamb. Heat the oil in a heavy Dutch oven or other large, lidded pot over medium-high heat. Add the lamb in a single layer, working in two batches if needed, and brown it on several sides for about 12 minutes total. Avoid crowding the pan: if the pieces are packed tightly, they release moisture and turn gray instead of developing a browned surface. Transfer the lamb to a plate; leave the browned bits and a thin film of fat in the pot.
Soften the onions and add the flour. Reduce the heat to medium. Add the onions and cook for 5 minutes, stirring often, until softened and beginning to turn translucent. Sprinkle in the flour and stir for 1 minute so it coats the onions and cooks briefly; this gives the broth a little body without making it into a thick gravy.
Build the braising liquid. Pour in about 1 cup (240 ml) of the stock and scrape the bottom of the pot with a wooden spoon to loosen the browned bits. Stir until the flour is smooth, then add the remaining stock, bay leaves, thyme, salt, and pepper. Return the lamb and any juices on the plate to the pot. Bring the liquid just to a gentle simmer, which should take about 4 minutes; do not let it boil hard.
Braise the lamb. Cover the pot, reduce the heat to low, and simmer gently for 70 minutes. Check occasionally to make sure the liquid is barely bubbling and the bottom is not scorching. If your stove runs hot, lower the heat. The lamb will not yet be fully tender, but this first simmer gives it a head start before the vegetables go in.
Add the potatoes and vegetables. Stir in the potatoes, carrots, and celery, then cover the pot again. Simmer gently for 38 minutes, stirring once or twice with care so the potatoes do not break apart. The vegetables should be tender when pierced with a fork, and the lamb should be easy to cut. If the potatoes are not quite tender, continue simmering in 5-minute increments. Check the largest lamb piece with a food thermometer: USDA FSIS lists 145°F (63°C) followed by a 3-minute rest as the safe minimum for whole cuts of lamb; for stew, keep simmering until the meat is also fork-tender.
Finish and rest. Remove the bay leaves. Taste the broth and adjust the salt and pepper. Take the pot off the heat and let the stew stand, covered, for 10 minutes; this gives the broth a chance to settle and makes serving easier. Sprinkle with parsley and ladle into warm bowls.

Tips

Choose lamb shoulder for a tender result. Shoulder has enough connective tissue to become succulent during a slow braise. Lamb stew meat is convenient, but the cut and cube size may vary, so check tenderness and allow extra simmering if needed. Lean leg meat can be used, though it may be less forgiving if cooked for too long.
Keep the simmer gentle. A rolling boil can make lamb tougher and break the potatoes into the broth. Look for a few small bubbles around the edge of the pot. If the broth becomes too thick before the vegetables are tender, stir in a little hot water or stock.
Choose potatoes for the texture you want. Yukon Gold potatoes hold together while turning creamy at the edges. Russet potatoes break down more readily and will naturally thicken the broth; cut them into larger pieces and stir gently if using them. Avoid tiny pieces, which may collapse before the lamb is tender.
Brown in batches and season at the end. Giving the lamb room in the pot creates deeper flavor in the finished broth. Stock saltiness varies, so the listed salt is a starting point; taste only after the stew has simmered, then adjust rather than adding extra salt at the beginning.

Serving Suggestions

Serve Irish stew hot in deep bowls, making sure each portion gets a mix of lamb, potatoes, carrots, and plenty of broth. Chopped parsley adds a fresh contrast, while crusty bread or Irish soda bread is useful for soaking up the last of the liquid. A simple green salad, buttered cabbage, or steamed green beans makes a light side without competing with the stew.

If you are serving a group, warm the bowls first and keep the pot covered off the heat for its 10-minute rest. Put extra black pepper and bread on the table so diners can season their own portions. The broth is meant to be spoonable rather than very thick; if it seems thinner than you like, mash a few cooked potato pieces against the side of the pot and stir them back in before serving.

Variations

Use mutton instead of lamb: Mutton has a more pronounced flavor and can take longer to become tender. Use the same amount and method, but begin checking after the first 70-minute braise and expect to extend the cooking time before adding the potatoes. Add the potatoes only when the meat is starting to soften, so they do not overcook while the mutton finishes.

Make it without lamb: Beef chuck is a practical substitute and braises well, though the result tastes more like beef stew than Irish lamb stew. Cut it into the same size cubes and use beef stock. The timing may vary by cut, so judge the meat by tenderness rather than relying only on the clock.

Make a thicker broth: Use russet potatoes, or mash a few of the cooked Yukon Gold chunks into the liquid. For a clearer, lighter broth, leave out the flour and simply simmer uncovered for the final few minutes if the liquid needs reducing. Avoid adding a large amount of flour at the end, which can leave a raw flour taste.

Add another traditional-style vegetable: Some home versions include turnip or parsnip. Replace up to 8 oz (225 g) of the carrots with an equal weight of peeled turnip or parsnip, cut into similar-sized pieces. Turnip gives a mild, earthy note; parsnip tastes sweeter. Add either with the potatoes and carrots so the pieces soften together.

Storage and Reheating

Cool the stew promptly and refrigerate it within 2 hours of cooking, dividing a large batch among shallow containers if that will help it cool faster. Keep it covered in the refrigerator for 3 to 4 days. The broth may thicken as the potatoes release starch, and the lamb often tastes even more seasoned after a night in the refrigerator.

For longer storage, freeze the stew in airtight freezer-safe containers for up to 3 months for best quality. Leave a little room at the top for expansion. Thaw it in the refrigerator overnight rather than on the counter. Potatoes can become softer after freezing, but the stew remains suitable for reheating; stir gently to avoid turning them into mash.

Reheat only the portion you plan to serve, either in a covered saucepan over medium-low heat or in a microwave-safe dish, stirring occasionally until hot throughout. Add a splash of water or stock if the broth has become too thick. USDA FSIS recommends reheating leftovers to 165°F (74°C); check the center with a food thermometer. Do not leave reheated stew at room temperature for more than 2 hours.

Frequently Asked Questions

Can I make Irish stew ahead?
Yes. Cook it as directed, cool it promptly, and refrigerate it for up to 3 to 4 days. Reheat it gently to 165°F (74°C) before serving. If making it a day ahead, you can stop once the potatoes are tender; avoid repeated reheating, which can make the potatoes fall apart and the lamb dry out.

Why is my lamb still tough?
Lamb shoulder becomes tender through time at a gentle simmer, not through a high flame. If it is still chewy after the stated time, cover the pot and continue simmering in 10- to 15-minute increments, checking again each time. The age and size of the pieces and the steadiness of the heat can affect how long it takes.

Can I make this in a slow cooker?
Yes, but brown the lamb and soften the onions on the stovetop first for better flavor. Transfer them to the slow cooker with the stock, herbs, and flour mixture, and cook on low until the lamb is nearly tender. Add the potatoes, carrots, and celery for the final part of cooking so they do not become overly soft. Slow-cooker models vary, so use tenderness as your guide and follow the appliance instructions.

Can I use lamb with the bone in?
Yes. Bone-in lamb pieces add flavor, but they take up more room and make the stew harder to portion. Choose pieces that fit comfortably in the pot, simmer until the meat is tender, then remove the bones before serving. If bone-in pieces are large, the cooking time may be longer than for 1½-inch boneless cubes.

What if I do not have lamb stock?
Low-sodium beef stock is an easy substitute and gives a deeper, more robust flavor. Chicken stock also works, producing a lighter broth. If using water, the stew will taste less savory, so taste carefully at the end and adjust the seasoning; a small amount of extra thyme can help, but it will not fully replace stock.

Can I leave out the flour?
Yes. The flour is optional for a slightly fuller broth, not essential to cooking the stew. Skip it and continue with the stock, or mash a few potato pieces into the liquid near the end to thicken it naturally. If you need a gluten-free version, omit the flour and check that your stock is labeled gluten-free.
