This slow-cooker lamb stew is one of the best lamb stew recipes and a classic way to enjoy lamb! The low and slow cook time gives all of the flavors in the stew so much time to meld together.

What is traditional Irish Lamb stew?

Traditional Irish stew is a thick, chunky stew made up of tender chunks of lamb or mutton and a blend of root vegetables such as potato and onion, and sometimes carrot. You’ll see it commonly eaten on St. Patrick’s Day and other Irish holidays.

Some argue that adding anything else to the stew means it’s no longer traditional, but bulk up your Irish stew with additional veggies, herbs, and beer! You can easily make this recipe for lamb stew using a handful of ingredients. The slow-cooked lamb stew is bursting with a smoky flavor everyone will love.

Ingredients to Make Irish Lamb Stew

• Celery, Onion, and Carrot – make up a “mirepoix” which helps create a flavor base for the soup.
• Garlic – use freshly minced garlic cloves for the best flavor.
• Lamb – you’ll use both lamb shoulder and lamb shank for this recipe.
• Seasonings: Use a simple blend of salt, pepper, paprika, and oregano.
• Tomatoes – use canned and chopped tomatoes. No need to drain the can. It incorporates directly into the broth.
• Beer – use stout beer for a more traditional flavor. Guinness beer is a fan favorite.
• Beef Broth – a flavorful base for the soup. You could also use homemade bone broth.
• Potatoes – Russet potatoes work great, but other varieties will work as well. Baby potatoes are also perfect!
• Water and Cornstarch – whisk together to form a slurry which helps thicken the soup. You can also swap the cornstarch for arrowroot powder if preferred.
• Frozen Peas – adds color and a pop of texture.
• Fresh Parsley – for garnish!

While the beef stock is preferred, the chicken stock will work if absolutely needed. It won’t have the same Guinness Irish stew flavor, but the basic ingredients will make up for it.
