This is the Irish lamb stew you dream about. It’s loaded with meaty lamb chunks, tender vegetables and a umami-rich, tongue-coating sauce that you’ll want to sop up with a piece of soda bread or biscuit. This slow cooked lamb recipe is best made the day before you serve it. Plan accordingly.

Ingredients for guinness braised Irish lamb stew

  • Bacon – you can use regular or thick cut bacon.
  • Lamb – I use a boneless leg of lamb cut into chunks.
  • Leeks – a milder tasting oniony vegetable that grows in layers beneath the soil. Be sure to clean well before using.
  • Celery – for the mirepoix.
  • Onion – I used yellow onion, but red or white work too.
  • Carrots – to add color and sweetness.
  • Parsnips – they look like carrots but have a stronger vegetal flavor. Peel before cutting into chunks.
  • Potatoes – I used red waxy potatoes, but white or Yukon Gold work well too.
  • Thyme – you can use fresh or ¾ teaspoon of dried thyme.
  • Rosemary – you can use fresh or ¾ teaspoon of dried rosemary.
  • Bay Leaves – I used dried, but you can use fresh.
  • Consommé or Beef Broth – homemade or low-sodium store-bought.
  • Guinness Stout or other Irish Stout Beer
  • Frozen Pearl Onions – you can also use fresh, but they should be peeled and blanched before adding them to the stew.
  • Frozen Peas – any store brand will work.
  • Fresh Parsley – for garnish to add a fresh pop.
  • Butter – to use in the beurre marnier to thicken the gravy.
  • Flour – to use in the beurre marnier to thicken the gravy.
  • Browning Sauce (optional)

Tips on preparing the vegetables

  • Prep the vegetables BEFORE you start cooking. It streamlines the process.
  • Cut the onion in thin, slices (about ½” wide) from root to tip.
  • Leeks have many layers and as they grow in the soil, dirt oftentimes becomes trapped in between the layers. The most effect way to clean leeks is to cut them in half, vertically, then chop them into half-inch pieces, crosswise. Transfer the chopped leeks to a bowl filled with cool water and swish with your hands so that any dirt in between the layers falls to the bottom of the bowl. Scoop the leeks from the water with a spider or slotted spoon and transfer to a salad spinner to dry. (Trust me, you’ll see sand and grit at the bottom of that water bowl and you don’t want it in your Irish lamb stew.

What’s the best cooking vessel for Guiness Irish stew?

I recommend using a Dutch oven for this slow cooked lamb. It provides a constant, even heat and makes your house smell wonderful as it cooks (that’s one downfall of the Instant Potyou can’t smell what you’re cooking). That said, you can use an Instant Pot or Slow Cooker (though you’d have to brown the lamb in a separate pan before braising it).

Layering the stew with rich smoky flavors

This slow cooked Guinness Irish stew gets its deep flavors from a multitude of ingredients, starting with bacon. Crisping the bacon in the dutch oven renders fat that you’ll use to brown the lamb in and create a delectable fond.

searing lamb chunks for the stew recipe.

What kind of lamb chunks to use for this recipe?

Lamb Shank – Taken from the lower part of the back legs, lamb shanks have meat and collagen — perfect for slow braising — because the collagen will break down leaving a silky mouth feel to the sauce. The tougher shank also becomes meltingly tender.  If you can’t find chunked lamb shank, you can certainly use 3 or 4 whole shanks for this recipe. When the lamb is done braising, simply pull the meat from the bones and cut the lamb into bite size pieces or chunks.

Leg of Lamb – This is the cut I used for this Guinness Irish stew. Of course the leg works hard too, and this cut has a good strong flavor that’s able to stand up to the malty stout. Have your butcher cut the lamb from the bone and chunk it for you. If you can hold onto the bone to braise with the stew, it will add even more flavor to the slow cooked lamb.

Lamb Shoulder – The shoulder tends to be a tougher cut, because it’s constantly being worked, however, when you’re braising, those tougher cuts transform into fork-tender lamb chunks and are perfect for this recipe.

Browning lamb chunks an a Dutch oven

  1. Season the lamb with salt and pepper.
  2. Working in batches, brown the lamb in the hot bacon fat in the Dutch oven, turning the meat with a pair of tongs until all sides have browned.

  4. When all the lamb is browned, return it to the dutch oven and add the onions, celery, carrots, parsnips and leeks.

Sweat the vegetables with the lamb

  1. After stirring the vegetables into the lamb, place the lid on and let them sweat and simmer for about 3-4 minutes, just until they start to wilt and the onions and leeks become slightly translucent. 
  2. Add the bundle of thyme, fresh chopped rosemary, bay leaves and chunks of red potatoes to the Dutch oven.
  3. Stir to combine.

Braising liquid for the stew

The gaminess of lamb pairs perfectly with a good Irish stout like Guinness. For this Irish stew, I use a combination of consommé and Guinness stout to braise the lamb. As it cooks, the lamb becomes more tender and the braising liquid takes on the flavors of meat, vegetables and herbs to create a sauce that’s absolutely delectable.

The hard part…

About halfway through the braise, remove the Guiness lamb stew from the oven and add about half of the frozen pearl onions.

Stir them in well, so they’re mixed with the rest of the ingredients and return the stew to the oven for more braising time. During that last braise, the onions will cook down to a softer texture and further flavor the stock.

This is the hard part. Remove the lamb stew from the oven and don’t eat it.  (I know. It SMELLS SO GOOD). Instead, let it cool to room temperature, then refrigerate it overnight.

Removing fat from the stew

The difference between a rich, flavorful sauce and a greasy sauce is how efficiently you can remove the fat from the pot.  Sure, you can use a spoon and try to skim away as much as you can, however, I’ve found the refrigeration method to be the most effective.

When refrigerated, the fats harden into solids that can be lifted from the top of the stew and discarded. This leaves you with just the rich, meaty sauce and none of the excess grease. It’s noticeable in the finished product and you and your diners will appreciate that extra step.

The last steps for this Irish lamb stew recipe are adding more stout and consommé, so that there’s plenty of deeply concentrated, rich gravy and thickening the sauce.

Finishing the sauce for the Guinness lamb stew

  1. Place the dutch oven over medium heat and add the remaining consommé and Guinness stout.
  2. Heat the lamb stew just to the boiling point.
  3. While the stew is heating, mix together the butter and flour, by mashing it with the back of a fork until you have a thick paste and no dry bits of flour remain.
  4. When the stew boils, stir in the flour mixture until it’s dissolved in the lamb stew and the sauce thickens.
  5. Stir in the frozen peas and parsley (the residual heat from the stew will warm the peas).
  6. Serve with the reserved crispy bacon, if desired.

So, come on. Doesn’t this look amazing? I only wish you could be in the kitchen to appreciate the savory aromas that wafted through the house.

My friend, Nola, came over as the Irish lamb stew was cooling (on the first day) and her first words were, “Oh wow! Lisa, what SMELLS SO GOOD?” I can’t tell you how disappointed she was that it wouldn’t be ready until the next day, because she was actively searching my kitchen drawers for a fork. Make this for your St. Patrick’s Day celebrations and be sure to serve it with some extra Guinness to wash it all down.

INGREDIENTS:

  • 1 leek
  • 2 stalks celery diced
  • 1 medium yellow onion thinly sliced
  • 3 carrots peeled and cut into 1″ pieces
  • 4 slices bacon chopped
  • 3 pounds lamb chunks from a leg of lamb, chunked into 1″ pieces, excess fat and silver skin trimmed
  • 2 parsnips peeled and cut into 1″ pieces
  • ½ pound red skinned potatoes cut into bite sized chunks
  • 4 sprigs thyme tied with a string
  • 1 teaspoon freshly chopped rosemary
  • 2 bay leaves
  • 2 cups beef broth or consomme divided
  • 2 11 ounce bottles Guinness or other irish stout divided
  • 10 ounces frozen pearl onions
  • 1 cup frozen peas
  • ¼ cup chopped parsley
  • tablespoons butter
  • tablespoons flour
  • 1 teaspoon browning sauce optional

DIRECTIONS:

  • Preheat oven to 325 degrees.
  • In a large dutch oven, brown the chopped bacon over medium high heat. Transfer crisped bacon to a paper towel lined dish. Set aside.
  • In two or three batches, brown lamb in dutch oven, using bacon fat to sear the meat. Use tongs to turn the chunks of lamb over and brown all sides.
  • Add all the lamb back to the pot and stir in the leeks, celery onion, parsnips and carrots. Cook over medium heat for 3-4 minutes until vegetables begin to soften. Stir in the potatoes.
  • Tie the thyme bundle with a kitchen string and add to the pot. Add rosemary bay leaves, 1 cup of broth and 1 bottle of stout. Heat just to boiling, place the lid tightly on the pot and transfer to the oven. Braise for 1 1/2 hours. Add the pearl onions and braise for an additional hour.
  • Remove the stew from the oven. Let the lamb stew cool to room temperature and refrigerate overnight.
  • The next day, scoop any solid fats from the stew and discard.
  • Place the stew over medium heat to warm through. Stir in the remaining beef broth and Guinness stout, heat just to boiling.
  • While the lamb stew is reheating, combine the flour and butter in a small bowl. Mash together with the back of a fork to form a paste (aka beurre marnier). Once stew is simmering briskly, stir in the butter mixture until it dissolves in the stew and the stew thickens.
  • Stir in the browning sauce, if using. Add frozen peas and parsley and stir to combine. The heat from the stew will thaw the peas. Serve.

NOTES:

Note: You can top the stew with the reserved bacon that was rendered on the first day. (I would have done that, but my husband found the reserves — and you guessed it — he ate them).

    I was in Dublin last week and couldn’t find lamb stew anywhere. Lots of beef and Guinness stews, but no lamb stew. Since things cooled down quite a bit in North Texas, I decided to give your recipe a try. I’m on the second round in the oven right now and can’t wait to try it. I’m also going to make mashed potatoes on the side, and probably going to serve it for dinner this evening, after adding the beurre marnier, and the browning sauce. Going to make a loaf of soda bread too.

  2. 5 stars
    Looks amazing however I don’t see any reason at all to let it sit over night just to take off any fat.
    I’ll just continue with the directions and totally skip that part.
    I’ll also just make a simple roux instead of mashing the butter and flour together and adding it in.
    I’m now exited to try it.

    Have done it once and will be doing it soon for Saint Patties again. Absolutely delicious and wonderful recipe and the day before preparation is critical, used Murphy’s stout which is a little sweeter. This time I will omit the potatoes in the stew to prepare them mashed and on the side (yellow potatoes for a silk like texture). I know it will be out of this world. 10/10

    1. That sounds like a plan! Mashed potatoes are perfect for the stout gravy!
