I cannot think of many more iconic dishes than the classic Sunday Roast Lamb. This was a staple of my household growing up. You could guarantee that come Sunday at around 4 – 5pm those delicious roast Lamb smells would start to spread all over the house so you knew what was coming! That classic Sunday Slow Roast Lamb Shoulder with some delicious vegetables and you better believe there’ll be some gravy right there with it

Lamb in the USA

Since moving to the US what was a bit of a surprise to us was that Lamb is considered in some circles as a bit more of an exotic cut of meat compared to the classic Chicken, Beef or Pork. It can be referred to as a little bit ‘gamey’, similarly to how I would think a cut of Venison, or Bison would be described. Maybe it’s because we grew up eating Lamb, but we would never really consider Lamb to be a game meat. So if you’re a little bit cautious about Lamb, please don’t be and give it a try. We guarantee you’ll love it just as much as we do!

Slow Roast Lamb Shoulder


  • 4 lb. Lamb Shoulder (approx. 1.8 kg)
  • 12 Garlic Cloves, peeled
  • 4 Sprigs Rosemary
  • 2 tbsp. Olive Oil
  • 2 tbsp. Salt
  • Optional: 1 lb. Roasting Vegetables


  1. First step, and very important is remove the Lamb from the fridge and bring up to room temperature before cooking. If you cook the Lamb when it is cold, the inside will cook much slower than the outside, so you’ll have an uneven cook
  2. Once at room temperature, prepare the Lamb by cutting small, 1-inch holes across the top and sides. Insert a Garlic Clove and small piece of Rosemary into each hole. This is a nice little trick to help infuse the Lamb with a lovely Garlicky, Rosemary flavor
  3. Place the Lamb in a large baking tray then drizzle the Olive Oil across the top of the Shoulder (the fatty part). Season liberally with Salt
  4. Optional Step: Place Roast Vegetables such as Potatoes, Squash, Celeriac and Onions around the rest of the pan along with the Lamb. As the Lamb cooks the fat will render and coat these Vegetables giving them the most delicious flavor
  5. Place the Lamb in an oven pre-heated to 430 degrees and roast for 20 minutes. Then reduce the heat down to 370 and continue to roast. The general rule for Roasting Lamb Shoulder is 30 minutes for every pour. So, for a 4 lb. Shoulder you should Roast in total for 120 mins / 2 hours
  6. Once the internal temperature of the Lamb reads 130 degrees remove from the Oven and rest. The Lamb will continue to cook while resting while all the juices within the meat settle. After resting for 20 minutes the Lamb is ready to carve and serve

The pan juices can be used to create a brilliant gravy for the Lamb as well. Simply combine a little flour and water then heat while stirring slowly until you get the perfect gravy consistency. We would highly suggest serving this Lamb along with some beautiful Roasted Vegetables and our Pickled Onions (recipe here) which cut through the fattiness of the lamb perfectly
