This Roast Lamb Shoulder will be an amazing centerpiece whether it is for a Sunday Roast dinner or for a special occasion such as Thanksgiving or Easter.

It requires the minimum hands-on time, simply put everything on a tray and let the oven do the rest.

And the best part is that you don't need to worry about undercooking or overcooking the lamb!

Why This Recipe Works?

• Low cooking temperature and a slow cooking time allow for the most succulent lamb meat.

• The lamb shoulder is a beautifully rich & tender cut of meat that tastes great when cooked with garlic and fresh rosemary. 

• Same as the Kuzu Tandir Kebab - Turkish Roasted Lamb and Boneless Leg of Lamb recipes, this slow-cooked lamb requires minimum preparation, you can dump it in the oven and entertain your guests!

• Slow Roast Lamb Shoulder is a great way to feed a crowd if you have a lot of people to serve for roast dinner. If you manage to have some leftovers, there are many ways to use them. You can make Maqluba (Makloubeh), or Slow Cooked Lamb Ragu with leftover lamb, or simply use them in a sandwich or wrap!

• The juices from the lamb mixed with the stock, rosemary, onions, and garlic make an incredible base for homemade gravy.

Lamb Shoulder

The shoulder of lamb is a tougher cut of meat with a generous amount of fat on top as well as marbled throughout the whole joint.

It is perfect for slow cooking at a low temperature, allowing the fat to melt throughout the joint, and giving you soft and juicy fall-apart meat.

The lamb shoulder is my favorite cut of meat and I use it for my other lamb recipes such as Tavë Kosi (Elbasan Tava), Guvec (Turkish Lamb Casserole), and Sac Kavurma (Turkish Lamb Sauté).

Also, it is a slightly cheaper joint than a leg of lamb but when cooked properly, it tastes as delicious.

This recipe is for a large lamb shoulder that weighs around 2.7 kg - 2.9 kg (6 lbs - 6.4 lbs). It is enough for big parties of up to 8 people and requires 4 hours of cooking time.

Ingredients You'll Need

Please scroll down to the recipe card below for the full ingredients list with measurements, complete recipe method, recipe notes, and nutritional information.

• Lamb shoulder - I used a large lamb shoulder that weighs 2.7kg (6lbs) for this recipe. The cooking time varies depending on the size. For a smaller size shoulder or half of a shoulder, cook for 3 hours, or until the lamb is falling off the bone easily.

• Rosemary - Fresh rosemary is a great flavoring for lamb and I use it generously. You can use thyme or bay leaves if you prefer.

• Garlic - 2 heads of garlic will give an amazing flavor to the lamb and also to your homemade gravy. I cut them in halves and use them to elevate the lamb. After the lamb is cooked, I keep the roasted garlic to use for flavoring soups and stews.

• Onions - They add a slightly sweet flavor to the lamb while cooking. Any onions would work for roast lamb shoulder.

How to Slow Roast a Lamb Shoulder?

Making this tender and juicy Slow Cooked Lamb Shoulder is surprisingly easy and straightforward.

Here are a few simple steps that you need to follow:

Cook the Lamb Shoulder

Rub the lamb shoulder all over with salt and pepper. Set it aside to marinate at room temperature for 1 hour. 

Preheat the oven to 140° C (285° F). Cut the garlic heads in halves.

Peel and cut the onions in halves and place them on a large and deep baking tray along with rosemary sprigs and garlic heads.

Place the lamb shoulder on top of the flavorings and add 1 liter of water to the tray.

Cook the lamb for 4 hours, or it falls apart easily when touched with a fork.

Place the lamb into a large plate cover it with tin foil, and let it rest somewhere warm for 30 minutes.

While resting the lamb, start preparing the gravy. 

Prepare the Gravy

Remove as much fat as you can from the oven tray, add the ½ liter of stock, and place it on medium heat.

Deglaze the pan, making sure you scrape all the brown goodness into the stock.

Let it boil for 10 minutes, remove from the heat, and then pass it through a fine chinois or a sieve into a small saucepan.

Press firmly on the vegetables to squeeze all the juice out of them.

Place the saucepan on medium-low heat and let the stock simmer for another 15 minutes.

Prepare the slurry by mixing 2 tablespoons of cornflour with 3 tablespoons of cold water.

Slowly whisk the slurry into the gravy. Let it simmer for a couple of minutes then remove the pan from the heat. 

Taste the gravy and add seasoning, if necessary. You rarely would need extra seasoning.

Transfer it into a sauce jug and serve it with plated Slow Cooked Lamb Shoulder meat and your favorite side dishes.

Top Tips From the Chef

• Take the meat out of the fridge at least an hour before cooking to ensure it reaches room temperature.

• Make sure to keep the meat raised on some onions and garlic as they will add extra flavor to the gravy and also keep the lamb out of the liquid. You can also use some celery and/or carrots with or instead of onions and garlic.

• The cooking time for the lamb shoulder depends on the size of the joint and the temperature/efficiency of the oven. You can use a fork to check if the lamb shoulder is cooked. When you can pull the shoulder bone out easily, leaving just the meat behind, your Slow Roasted Lamb Shoulder is ready to take out of the oven.

• To easily separate the lamb fat from the stock, pour it into a jug and place it in a large bowl filled with ice. When the stock is cooled down, put it into the freezer to help the fat layer set. When the fat is set on top, remove it using a spoon and your stock is ready for making the gravy.
