Roast Leg Of Lamb

Ingredients

• 6 pounds leg of lamb, bone-in – trimmed of thick surface fat and silverskin, patted dry
• 8 cloves garlic cloves – cut into thin slivers
• 2 tablespoons fresh rosemary – leaves finely chopped
• 1.5 tablespoons kosher salt
• 2 teaspoons black pepper – freshly ground
• 3 tablespoons olive oil
• 0.5 cups dry white wine
• 1 cups low-sodium chicken stock
• 1 tablespoons unsalted butter – cold

Instructions

1. Set the lamb out at room temperature for 45–60 minutes. Heat the oven to 425°F and place a rack in the lower third. Set a roasting rack in a sturdy roasting pan.
2. Trim away any thick, hard fat and silverskin, leaving a thin fat cap. Score the fat in a shallow crosshatch (about 1/2 inch apart), taking care not to cut into the meat.
3. Cut the garlic into thin slivers. Using the tip of a small knife, make 1-inch-deep slits all over the lamb (about 20). Tuck a garlic sliver into each slit.
4. In a small bowl, mix the chopped rosemary, kosher salt, black pepper, and olive oil into a paste. Rub this all over the lamb, working it into the scored fat. Place the lamb on the rack, fat side up.
5. Roast at 425°F until the surface is lightly browned, about 20 minutes.
6. Reduce the oven to 350°F. Pour 1/2 cup of the chicken stock into the roasting pan to prevent drippings from scorching. Continue roasting until an instant-read thermometer inserted into the thickest part (not touching bone) registers 125–130°F for medium-rare or 135°F for medium, 60–90 minutes more (about 12–15 minutes per pound). Rotate the pan once for even cooking if needed.
7. Transfer the lamb to a carving board and tent loosely with foil. Rest 20–30 minutes so the juices redistribute.
8. Place the roasting pan across two burners over medium heat. Add the white wine and scrape up any browned bits, simmering until reduced by about half, 3–5 minutes. Add the remaining 1/2 cup chicken stock and simmer until the sauce is slightly syrupy, 3–5 minutes more. Off the heat, whisk in the cold butter until glossy. Strain the jus if desired and keep warm.
9. Carve the lamb by cutting along the bone to remove large sections, then slice across the grain into serving pieces. Serve with the warm pan jus.
