Slow Cooker Irish Stew

Did I ever tell you that my maternal grandma was Irish? She used to tell me stories about her early years living in Ireland before moving to England when she was still a child.

I used to ask her to tell me more as Ireland just sounded so interesting.

Well, she married a guy from Yorkshire (my grandad), they had five daughters and they lived happily ever after.

One way that my grandad was always trying to impress my grandma was with his cooking and he had mastered an amazing irish stew. He would always cook it with Guinness, it was always hearty, and filling and it was always loaded with leftover lamb neck fillets that he had got on a deal from the butchers.

Even when he had too much of the Guinness and salted it twice, I would still enjoy every last mouthful and look forward to the next time.

Today, I wanted to share with you, how you too can make a proper traditional Irish stew in the slow cooker.

Can You Put Raw Lamb In A Slow Cooker?

Yes, you can put raw lamb in a slow cooker. Just like with any slow cooker meat, you can dump it in with the other ingredients, mix it and then you have slow cooker stew.

But you have a better Irish lamb stew slow cooker recipe, if you brown your meat first.

Do You Have To Brown Lamb Before Slow Cooking?

No, its not essential to brown your lamb before slow cooking, but I do recommend you do it.

This is because it adds extra flavour to the lamb and lamb also carries a lot of extra fat, so you can then drain the lamb fat, before you slow cook your Irish stew.

For example, this is the liquid we created after browning our lamb neck.

How Do I Make Lamb Stew Meat Tender?

You slow cook your lamb. Lamb is perfect for stews and casseroles and by dumping your lamb and cooking it for 4 hours in the slow cooker produces the best results.

If you want your lamb to fall off the fork as you tuck in, then you can increase the cook time to 5 hours to achieve this.

What Is Traditional Irish Stew?

Traditional irish stew is cooked in the slow cooker and is loaded with lamb neck fillets that have been diced, carrots, potatoes, celery, tomato puree and a full can of Guinness.

You will find many Irish stews that are not traditional because they don’t use Guinness, or they substitute lamb for beef.

Irish stew is often referred to as a lamb and Guinness stew or as a lamb neck stew.

How Do You Make Irish Stew Better?

One ingredient that I often see in a slow cooker irish lamb stew is flour to thicken up the stew.

I recommend NOT using flour and instead to drain your lamb stew after you have finished slow cooking.

Then reserve half of the liquid as lamb stock for future recipes and then place the other half back in.

Then add a big spoonful of mashed potatoes and stir it in.

You will then have a yummy gluten free Irish stew without it feeling heavy and grainy from the flour.

Guinness Irish Stew

One ingredient that is not familiar to many, when making a traditional irish stew is Guinness.

Well, what the Guinness does is replace part of the stock. Don’t expect a stew that all you can taste is ale, because that is not the case.

I do recommend pouring your Guinness into a glass an hour before cooking. It will reduce the head on it and make it easier for cooking with.

Though because we don’t drink much, we don’t have any pint glasses, so used two smaller ones.

Irish Stew Slow Cooker Ingredients

Irish Stew Slow Cooker Ingredients

Lamb – I recommend you use lamb neck fillets that have been diced ready for a stew, or you slice them up yourself.

Guinness – What makes an Irish stew stand out from the crowd, is the addition of Guinness. Once you try a Guinness stew in the slow cooker there is no going back. You will only need 1 can for 1 big hearty stew.

Stock – I make big batches of stock in the instant pot, freeze it, and then use it in my slow cooker meals. You can load frozen stock cubes into the slow cooker too. If you don’t have lamb stock you can sub it for chicken or vegetable. Then for extra stock I also add in some tinned tomatoes. Avoid water if you can, as it will make your stew taste like dishwasher water.

Veggies – Go traditional and add potatoes, carrots, celery, and onion. Or mix it up and add some swede or parsnips.

Seasoning – when making irish stew in slow cooker I recommend for seasonings salt, pepper, rosemary, chives, and thyme.

    Unfortunately I found the Guinness in this recipe made it taste rather bitter to me, and it overshadowed the taste of the lamb. Easy prep and cook though.

    • Hi Brenda,

      Sorry it made it bitter for you , we tried with some different stouts first and lagers and beers and thought Guinness was the best tasting. Glad you found the recipe easy 🙂
