Guinness Lamb Stew

This Guinness Lamb Stew is hearty, rich and deeply savory, with chunks of tender lamb simmered in a dark stout broth alongside potatoes and vegetables. The Guinness adds depth without bitterness, creating a stew that's bold, comforting and full of classic Irish flavor.

This is the kind of meal that's perfect for colder nights, slow weekends or anytime you want a dinner that simmers gently and fills the house with good smells. It's especially fitting for St. Patrick's Day, but just as welcome on a rainy evening when comfort food is calling.

If you enjoy hearty, slow-simmered meals, our Cottage Irish Pie delivers similar comfort with a baked finish. Our Roast Leg of Lamb recipe is a great option if you want something more traditional for a special dinner

Ingredients

This stew uses simple ingredients layered together to build depth and richness over time.

See the recipe card below for the exact quantities of each ingredient.

• Vegetable Oil and Unsalted Butter: Help sear the lamb and build flavor at the base of the stew.
• Lamb Shoulder: A well-marbled cut that tenderizes with slow cooking.
• Carrots: Add sweetness and balance to the rich broth.
• Yellow Onion: Forms the aromatic base of the stew.
• Garlic: Adds warmth and savory depth without overpowering the lamb.
• Tomato Paste: Concentrates flavor and adds body to the broth.
• Beef Stock: Creates a savory foundation that complements the lamb.
• Guinness Beer (Dark Stout): Adds depth, richness and a subtle malty note to the stew.
• Fresh Rosemary Sprigs: Infuse the stew with earthy flavor, then get removed before serving.
• Worcestershire Sauce: Enhances umami and rounds out the broth.
• Sea Salt and Black Pepper: Season the stew and bring all the flavors together.
• Baby Potatoes: Make the stew hearty and filling while holding their shape.
• All-Purpose Flour: Thickens the stew slightly for a spoonable, rich texture.
• Frozen Peas: Add color and freshness right at the end.
• Water: Adjusts the consistency to your preference as the stew simmers.

You'll only need a few kitchen essentials to get started with this Guinness stew. Grab your measuring cups and spoons along with a large Dutch oven, and you're ready to make dinner tonight.

Variations

• No Beer Option: Skip the Guinness and replace it with additional beef broth.
• Broth Swap: For a more traditional, deep flavour of lamb, use a lamb stock; if all you have is chicken stock that will work too.
• Slow Cooker Version: Allow the Crock Pot to do most of the work, follow our Slow Cooker Lamb Stew recipe.
• Herb Swap: Use fresh thyme or bay leaves instead of rosemary for a slightly different flavor profile.

How to Make Guinness Lamb Stew

This Irish lamb stew comes together in stages, which builds flavor and makes the meat extremely tender.

Heat a large skillet over medium high heat and some oil and butter while working in batches and lightly sear the meat on all sides (I find it saves time to use bigger chunks and allow them to rest then cut into bite-sized pieces, but you can do that in reverse).

Once complete with all the meat, transfer to plate (if desired lightly salt the meat while resting).

If desired, you can remove some of the fat that has gathered from the meat, then add carrots and onion and cook until soft, then garlic for 1 minute. Reduce the heat to medium if needed.

Cook tomato paste for 2 minutes, then add beer and deglaze the pan for about 3 minutes scraping up the browned bits from the bottom of the pan (it should be thick).

Add browned lamb and rosemary sprigs, Worcestershire, salt and pepper.  Mix well and bring to a boil, then reduce to low and cook for an hour, covered (keep a light boil going the whole hour).

Remove the rosemary sprigs and add potatoes to the Dutch oven and cook for an additional 45-60 minutes, uncovered or until the potatoes are almost fork tender. 

Once the potatoes are cooked, taste and add any additional season, or water if desired at this time. Then combine flour and ½ cup water to a spouted measuring cup and whisk. Pour this into the pot and bring to a rolling boil (not too aggressive) for about 15-20 minutes or until it has thickened slightly.

When ready to serve add in the peas and stir to combine (they will warm up and soften quickly). Garnish with fresh parsley if desired.

Hint: Sear in batches to properly build deep flavor in the finished stew.

Recipe Tips

• Cook the Tomato Paste: Letting it darken slightly removes acidity and adds richness.
• Remove the Rosemary: Pulling the sprigs before thickening prevents overpowering herbal notes.
• Thicken Gently: Bring the stew to a controlled boil so it thickens without becoming heavy.

For another comforting, slow-cooked meal, our Slow Cooker Brisket is a great option when feeding a crowd.

Storage Instructions

• Refrigerator: Store leftovers in an airtight container for up to 4 days.
• Freezer: Freeze cooled stew in freezer-safe containers for up to 3 months.
• Reheating: Warm gently on the stovetop, adding a splash of broth or water if needed.
• Make Ahead: This stew tastes even better the next day as the flavors continue to develop.

Serving Suggestions

• Soups and Stews: Crock Pot Lamb Stew, Crock Pot Beef Stew, Slow Cooker Split Pea Soup, Italian Penicillin Soup or Zuppa Toscana.
