Rosemary and Thyme Braised Lamb Shoulder

This slow-braised rosemary and thyme lamb shoulder is a magnificent centrepiece for a traditional Sunday roast. By marinating the lamb in a fragrant paste of garlic, lemon zest, and fresh herbs for up to 24 hours, the meat becomes deeply infused with flavour while the slow-cooking process ensures a melt-in-the-mouth texture. Using the natural juices to produce a light, herb-flecked gravy keeps the dish lean and wholesome without compromising on the rich, savoury depth that makes lamb so popular.

As a diabetes-friendly main course, this dish focuses on high-quality protein and aromatics rather than sugary glazes or heavy fats. The lamb is gently simmered in a mixture of dry white wine and water, resulting in a tender finish that can be pulled apart effortlessly with a fork. Serve this homemade favourite alongside a generous portion of steamed seasonal greens and roasted root vegetables for a balanced, heart-healthy meal the whole family will enjoy.

  • 2 tablespoons plain flour

  • 1/2 teaspoons minced fresh rosemary

How to make Rosemary and Thyme Braised Lamb Shoulder

Make slits in lamb shoulder all over at 2-inch intervals with a paring knife.

Pound garlic with kosher salt, zest, and 1/2 teaspoons black pepper to a coarse paste with mortar and pestle (or mince and mash with a large knife), then stir together with oil and 1 tablespoon each of rosemary and thyme. Rub paste all over lamb. Put in heavy pot or roasting pan, then chill, covered, 12 to 24 hours.

Bring roast to room temperature (about 1 hour).

Preheat oven to 177°C with rack in lower third.

Pour wine and water around lamb and add herb sprigs. Cover roast with a sheet of parchment. Cover pot with lid or cover roasting pan tightly with heavy-duty foil. Braise lamb in oven until tender but not falling off the bone, about 3 hours.

Increase oven to 232°C and remove parchment, then braise lamb, covered with lid (or foil), until very tender and top is browned, about 1 hour more. Carefully transfer lamb to a platter and loosely cover with foil. Let it stand 10 minutes.

Pour braising liquid through a fine-mesh sieve, then spoon off and discard fat remaining on liquid (you should have about 475ml liquid; reserve pot). Whisk together flour and 240ml liquid in a small bowl until smooth. Bring remaining liquid to a boil in uncleaned pot, then whisk in flour mixture and boil, whisking, until thickened, about 4 minutes. Stir in thyme and rosemary and season with salt and pepper.

Remove and discard strings. Meat is too tender to slice with a carving knife; use a meat fork to pull meat into serving pieces.
