This Irish lamb stew recipe has tender lamb, carrots, and potatoes simmered in a rich, savory broth with Guinness and fresh rosemary.

This Irish lamb stew recipe is hearty, deeply flavorful, and just the thing for a cold day. It starts with chunks of lamb shoulder, which are browned and then slowly simmered in a Guinness-spiked broth until fork-tender. Carrots, potatoes, and peas make it a complete one-pot meal.
The Guinness gives the broth a rich, malty depth without making the stew taste strongly of beer. And like most stews, this one is even better after the flavors have had time to meld, so it’s a great dish to make ahead. Serve it with Cheddar soda bread for soaking up the broth.
“I doubled the recipe for a group of nine to celebrate St. Paddy’s Day and everyone loved it. It was very tasty and the lamb was nice and tender.”
What You’ll Need To Make Lamb Stew With Vegetables

- Lamb shoulder: Ideal for stew because it becomes tender and succulent with slow cooking. Trim away any large pockets of exterior fat before cutting it into chunks.
- Guinness: Adds malty depth and a subtle bitterness that balances the richness of the lamb. The stew won’t taste strongly of beer.
- Onion and garlic: Form the savory base of the stew and mellow as they cook.
- Tomato paste: Adds concentrated tomato flavor and savory depth without making the stew taste tomatoey.
- Flour: Lightly thickens the cooking liquid, giving the broth just enough body.
- Beef broth: Creates a rich, savory base for the stew. Use a good-quality broth since its flavor comes through.
- Rosemary and bay leaf: Add earthy, aromatic flavor that pairs especially well with lamb.
- Carrots and baby Yukon Gold potatoes: Both hold their shape well as they cook while becoming tender; the potatoes also have a naturally buttery texture.Frozen peas: Added near the end so they stay bright and fresh-tasting.

How To Make Irish Lamb Stew
Brown the lamb: Pat the lamb dry, season it, and brown it in batches so the pieces have plenty of room in the pot. Let them develop a deep brown crust before turning—those browned bits are what give the stew its rich flavor. Transfer the browned meat to large bowl and set aside.


Build the base: Cook the onions until softened, then add the garlic and tomato paste. Stir in the flour, followed by the Guinness, scraping up the browned bits from the bottom of the pot as you go. The mixture should look smooth and slightly thickened.




Simmer the lamb: Return the lamb to the pot and coat it with the flour, then add the Guinness, broth, and herbs. Scrape up all those browned bits as the liquid goes in, then let the stew simmer gently until the lamb is beginning to tenderize.


Add the vegetables and finish: Add the carrots and potatoes once the lamb has had a head start, then continue simmering until the vegetables are tender and the lamb yields easily to a fork. The broth should be rich and lightly thickened. Stir in the peas at the very end so they stay bright and fresh-tasting, then taste and adjust the seasoning before serving.


Can I Make Lamb Stew In A Slow Cooker?
Yes, but for best results, begin on the stovetop as directed up to the step of adding the Guinness and broth. Transfer everything to the slow cooker, including the carrots and potatoes, and cook on high for 4 to 5 hours, until the lamb is tender and the vegetables are cooked through. Stir in the peas just before serving.
How to Thicken Irish Lamb Stew
The stew will thicken as it cooks, so don’t worry if the broth seems thin at first. If you’d like it thicker at the end, mash equal parts softened butter and flour into a smooth paste (called a beurre manié). Bring the stew to a simmer, then whisk in the paste a little at a time until the broth reaches your desired consistency.

Ingredients
- 3 lb lamb shoulder, well-trimmed and cut into 1½-in (4-cm) pieces
- 2 teaspoons salt
- 1 teaspoon freshly ground black pepper
- 3 tablespoons vegetable or olive oil
- 2 medium yellow onions cut into 1½-in (4-cm) chunks
- 6 cloves garlic, peeled and smashed
- 3 tablespoons tomato paste
- ¼ cup all-purpose flour
- 1 cup Guinness
- 3 cups beef broth
- 2 cups water, plus 2 tablespoons more for cooking onions and garlic
- 1 bay leaf
- 1 small sprig fresh rosemary
- 2 teaspoons sugar
- 4 large carrots, peeled and cut into 1-in (2.5-cm) chunks on the diagonal
- 1 lb small white boiling potatoes (baby yukons), cut in half
- 1 cup frozen peas
Instructions
- Pat the lamb dry and season with salt and pepper. In a large Dutch oven or heavy pot, heat one tablespoon of oil over medium-high heat until hot and shimmering. Brown the lamb in three batches, adding one more tablespoon of oil for each batch. Do not crowd the pan and let the meat develop a brown crust before turning with tongs. It should take 5 to 8 minutes per batch. Transfer the browned meat to large bowl and set aside.
- Add the onions, garlic and 2 tablespoons of water to the pot. Cook until the onions are soft, stirring with a wooden spoon to scrape any brown bits from the bottom of pan, about 5 minutes.
- Stir in the tomato paste and cook a few minutes more.
- Add the lamb with its juices back to the pan and sprinkle with flour. Stir with a wooden spoon until the flour is completely mixed in, 1 to 2 minutes.
- Add the Guinness, beef broth, water, bay leaf, rosemary sprig and sugar. Stir with a wooden spoon to loosen any brown bits from the bottom of the pan and bring to a boil. Cover the pot with a lid, turn the heat down to low and simmer for one hour and twenty minutes.
- Add the carrots and potatoes to the stew, then cover and continue simmering until the vegetables are cooked and the meat is very tender, 30 to 40 minutes. (Be sure to stir a few times to prevent vegetables from sticking to bottom.)
- Remove the bay leaf and rosemary sprig, and then taste and adjust seasoning if necessary. If serving right away, add the frozen peas and cook until the peas are warmed through. Otherwise, let the stew cool, then cover and store in the refrigerator until ready to serve. Reheat gently on the stovetop and add the peas right before serving.

Can I make this recipe in a slow cooker? If yes, how many hours and at what level, high or low?
Hi, this can be done in a slow cooker — You’ll still need to go through all the initial steps like searing the meat on the stovetop, so not sure it’s worth it. If you choose to use a slow cooker, I’m not sure how long it will take (as I don’t have a slow cooker), but Martha Stewart’s website has an article that provides some guidance. I’d just go to marthastweart.com and search for “How to Convert Your Favorite Recipes for the Slow Cooker.” Hope that helps and that you enjoy the stew!
6 to 8 hours on low. Brown meat and veges before adding to slow cooker and deglaze. Reduce the water added by 50 percent 🙂
What can I substitute for the beer? Just more beef broth?
Yep 🙂
I am hoping to make this for a special St. Patrick’s Day dinner on Sunday, however, I am unable to find a lamb shoulder roast anywhere in my state (NH). A reputable butcher in the area has lamb leg, and he said it’s essentially the same thing, just a bit leaner. A should roast comes from the front leg, and a lamb leg comes from the back. Can I substitute lamb leg, and how can I ensure it doesn’t come out dry? We’re hosting my daughter-in-law’s British mum for dinner, and she’s half Irish. I have to get this right! 🙂
Hi Deb, You can use the lamb leg without any other modifications. The meat won’t be quite as tender, but the stew will still be good. Hope everyone enjoys!
I’d like to try this recipe. My family would like me to make Guinness stew, but nobody likes lamb. Could I make the recipe with beef? (I’m trying for an Irish style stew with Guinness rather than the French version with wine.). Thanks for your help.
Sure, it would be fine to use beef here. Hope everyone enjoys it!
Hi, Jenn,
I’m not a billionaire, so I am wondering if I can use ground lamb instead?
Thanks!
Rebecca
Hi Rebecca, I’ve noticed that lamb is very expensive right now. Unfortunately, ground lamb won’t work here though — sorry!
Hi
Am going to try this for first time this weekend .I love the beef one so am looking forward to this .
Can I cook this in either oven or the slow cooker .my preference would be slow cooker .would I need to reduce the liquid .
Thanks so much in advance
Brenda
Hi Brenda, This could be done in a slow cooker — You’ll still need to go through all the initial steps like searing the meat on the stovetop, so not sure it’s worth it. If you choose to use a slow cooker, here are some tips that may help you to adapt the recipe (and I believe the tips mention reducing the liquid). After going through all the initial steps, you could also put this in a 325-degree oven for the same amount of time that the stew simmers on the stove. Hope you enjoy!
I love this recipe!!!! I am gluten-free, so a straight swap for rice flour works perfectly to thicken this. I follow the exact same steps, and it is indistinguishable from its flour-thickened counterpart. I would not use a cornstarch slurry as it would look like dog food, you need it to be opaque like gravy. I also use more broth in place of Guinness when I don’t have GF beer.
Hello, can I substitute beef broth for lamb bone broth / lamb stock?
Sure!
How long does this recipe take from start to finish if I cube the lamb shoulder myself?
PS I love ALL of your recipes, and made two Blueberry Coffee Cakes yesterday for visiting friends and family, but made one with fresh strawberries-and they were both amazing!! Thanks for the great job you do, and for sharing your gifts and talents with all of us so generously online!
So glad you like the recipes! 🙂
I’d guesstimate you should allot 3 to 3.5 hours for the stew. Hope you enjoy it!
Hopefully this turns out ok. I had to sub out beef for lamb because I couldn’t find lamb anywhere in time, but it sure smells good thus far!
Just to note, I had this recipe/website up on my tablet and never before I have been so incredibly frustrated trying to follow along with a recipe, as pop-up ads would fill my screen about as quickly as I could clear them. Seriously, every single time I looked at the screen I had to adjust the window and remove ads just to see what I was trying to read. I realize you make money off this website and I don’t begrudge anyone trying to make a living, but when there are so many pop up ads that you can’t rightly follow the recipe you’ve gone WAY overboard.
Hi Sudz, So sorry for the frustration. Tablets can cause issues when looking at websites, especially if they are turned horizontally.
I have the same issues with my iPhone or iPad. I only have these problems with your site, not other recipe sites. Have you actually tried to read and use a recipe lately?So frustrated because I love your website.
I tried to comment on a couple of recipes lately but no luck.
Hi Phyllis, I’m sorry about the challenges you’re having! If you’d like, you can install an adblocker on whatever browser you use. I tried it and it really works! You still see some unobtrusive ads, but it’s a much better experience. It will also eliminate annoying ads on all websites you visit — not just mine. The only downside is that it blocks the videos too, and unfortunately, there is no way around that.
Another option is to view the recipe as if you were going to print it. That will remove all the ads. So, you’d go through the process of preparing to print a recipe and just view it that way. Hope those options help!
I have mac book there are ads on the right side , but no pop ups – love so many of your recipes !!
I take a screenshot of the recipe ingredients/directions which removes the frustration!
