Mary Berry Easter Lamb Shoulder is a traditional British roast featuring bone-in lamb shoulder seasoned with herbs, garlic, and citrus. Unlike quicker-cooking cuts, shoulder benefits from slow roasting, which allows the connective tissue to break down and create melt-in-the-mouth texture. The result is tender, deeply flavoured lamb with crisp edges and a rich roasting gravy.
Lamb shoulder (bone-in) – 2.2kg
Garlic cloves – 4, sliced
Fresh rosemary – 2 tablespoons, chopped
Lemon zest – from 1 lemon
Olive oil – 2 tablespoons
Sea salt – 1½ teaspoons
Freshly ground black pepper – 1 teaspoon
Onion – 1 large, sliced
Lamb or chicken stock – 250ml
Preheat the oven – Set oven to 170°C (150°C fan).
Prepare the lamb – Pat dry and score the skin lightly in a criss-cross pattern.
Insert flavour – Push garlic slices and rosemary into small slits across the surface.
Season generously – Rub with olive oil, lemon zest, salt, and pepper.
Prepare roasting base – Scatter sliced onions in the roasting tin and place lamb on top.
Add moisture – Pour stock around the base (not over the lamb).
Roast slowly – Cover loosely with foil and roast for 3–3½ hours.
Crisp the exterior – Remove foil for the final 30 minutes to brown the skin.
Rest properly – Allow the lamb to rest under foil for 20–30 minutes before carving.
