• 2 pounds (900g) diced lamb neck or shoulder
• 1 tsp salt
• ½ tsp black pepper
• 2 tsp thyme leaves fresh
• 2 leeks white parts only chopped
• 4 carrots cut into large pieces
• 3 potatoes peeled and cubed
• 1 tbsp tomato paste (optional)
• 1 tbsp Worcestershire sauce
• 4 cups (950ml) beef broth
• 11.2 fl oz (330ml) Guinness
• 1 bay leaf
• 2 tsp cornstarch diluted in 1 tbsp cold water
• 3 tbsp fresh parsley chopped

Method

 

1. Set your oven to 325°F (160°C) to preheat.
2. Heat olive oil in a large casserole over medium heat, add the bacon and cook until it’s slightly crispy.
3. Toss in the diced lamb to brown it well on all sides, then pour any meat juices into a separate bowl.
4. Pour a bit of Guinness or beef broth into the pan and scrape up all the browned bits from the bottom to capture the flavor, transferring this liquid to the bowl with the lamb.
5. Add a little more oil if needed and gently cook the leeks for about 5 minutes until softened.
6. Mix in carrots, potatoes, thyme, salt, and pepper, cooking everything together briefly for around one minute.
7. Pour the Worcestershire sauce, remaining Guinness, and beef broth into the pan, then bring everything to a gentle simmer.
8. Stir in the tomato paste if you’re using it, then return the lamb, bacon, and add the bay leaf.
9. Seal the dish with a lid and place it in the oven to cook for 90 minutes, until the lamb is tender.
10. Remove the stew from the oven, taste and adjust seasoning to your preference.
11. To thicken the gravy, stir in the cornstarch slurry and warm the stew until it thickens nicely.
12. Sprinkle the chopped fresh parsley on top and serve your stew with crusty bread for a comforting meal.

Notes

• 1: You can substitute the leeks with 1 large finely diced brown onion if preferred.
• 2: Guinness can introduce a slight bitterness; consider swapping it with another stout or ale if that’s not to your taste.
• 3: For a thicker stew without cornstarch, blend some of the cooking liquid with a few pieces of potato and carrot using an immersion blender.

• One-Pot Wonder: Everything happens in your casserole dishless cleanup means more time to actually enjoy dinner.

The Key Players in Your Pot

Let’s talk about what makes this stew sing. You’re working with honest, straightforward ingredientsnothing fancy, nothing you can’t find at your regular grocery store on a Wednesday afternoon.

The lamb is your star here. Neck or shoulder cuts have just enough marbling to stay moist through that long, slow braise. Don’t even think about using lean cutsyou need that fat to keep everything juicy. The streaky bacon adds a smoky, salty backbone that makes the whole pot taste richer without any extra steps.

Then there’s the Guinnessit’s traditional for a reason. That dark, slightly bitter note balances out the sweetness from the carrots and adds serious depth. If you’re not a Guinness drinker, don’t worry; it cooks down and mellows out completely. The beef broth, Worcestershire sauce, and tomato paste round out the gravy, giving you that glossy, stick-to-your-ribs texture.

How to Build the Stew Step by Step

Start by preheating your oven to 325°Fyou want it ready to go once everything’s in the pot. Heat your olive oil in a big casserole dish and toss in that chopped bacon. Let it sizzle for a couple minutes until it’s starting to crisp up and smell amazing.

Next, add your diced lamb. Don’t crowd itlet it get a good sear on all sides until it’s nicely browned. This is where the flavor lives, so don’t rush it. You’ll end up with some liquid in the pan; just transfer it to a bowl along with the meat. Pour a splash of Guinness or broth into the hot pan and scrape up all those stuck-on brown bits with your wooden spoon. That’s liquid goldadd it to the bowl with the lamb.

Now add a bit more oil if your pan looks dry, then cook the leeks for about five minutes until they’ve softened. Toss in the carrots, potatoes, thyme, salt, and black pepper. Stir it all around for a minute, then pour in the Worcestershire sauce, the rest of the Guinness, and the beef broth. Bring everything to a simmer, stir in the tomato paste if you’re using it, then add back the lamb, bacon, and toss in a bay leaf. Pop the lid on tight and slide it into the oven for 90 minutes.

The Final Touch

When the timer goes off, check the lambit should be completely tender and practically falling apart. Adjust the seasoning if it needs it, then stir in your cornstarch slurry (just cornstarch mixed with a little cold water). Let it heat through on the stovetop for a minute or two until the gravy thickens up beautifully. Finish with a sprinkle of fresh parsley and you’re done.

Pro Tip: If you want to skip the cornstarch, use an immersion blender to blitz a few pieces of potato and carrot right in the pot. It thickens the gravy naturally and adds even more body.

Timing and Temp at a Glance

Tweaks, Swaps, and Troubleshooting

If you’re not a fan of Guinness, don’t let that stop you. The beer does cook down and lose most of its bitterness, but if you really don’t like the flavor, just swap it out for a different stout or ale. You could even use all beef broth if you want to skip the beer entirelyit’ll still be delicious, just a little less traditional.

No leeks? No problem. Use one large brown onion, finely diced. It’ll add a sharper bite but still work beautifully. And if you want a thicker stew without any cornstarch, that immersion blender trick is your best friend. Just blend a few chunks of potato and carrot right into the braising liquid and it’ll thicken up naturally.

• Too thin? Simmer uncovered on the stovetop for 10 minutes, or add a bit more cornstarch slurry.
• Too thick? Stir in a splash of beef broth or water until it looks right.
• Lamb not tender? Give it another 20–30 minutes in the oven. Every cut is a little different.
• Want more veg? Toss in parsnips or turnips along with the carrots and potatoes.

Serving and Storing Your Stew

This Irish Lamb Stew is begging to be served with a hunk of crusty bread for soaking up that gravy. Ladle it into wide, shallow bowls so you get a good mix of meat, vegetables, and broth in every spoonful. A sprinkle of fresh parsley on top adds a little brightness and makes it look as good as it tastes.

Leftovers are honestly one of the best parts. Let the stew cool completely, then store it in an airtight container in the fridge for up to four days. The flavors deepen overnight, and reheating it on the stovetop or in the microwave is a breeze. You can also freeze it for up to three monthsjust thaw it in the fridge overnight before reheating.

Note: If you’re planning to freeze it, consider slightly undercooking the potatoes. They can get a little mushy after freezing and reheating, but they’ll still taste great.

Expert Says

Irish lamb stew benefits from low and slow cooking, which breaks down the collagen in tougher cuts like shoulder or neck into gelatin, creating that signature silky texture. The root vegetables add natural sweetness and thickening starches, while lamb provides high-quality protein and essential minerals like iron and zinc for a truly nourishing one-pot meal.
