How to Make Roasted Boneless Leg of Lamb
Preheat the Oven: Set your oven to 375°F (190°C). This ensures the lamb cooks evenly and achieves that perfect, juicy tenderness.
Prepare Your Rub: In a mixing bowl, combine crushed garlic, chopped rosemary, lemon juice, Dijon mustard, olive oil, kosher salt, and fresh ground black pepper. Mix until it forms a paste that s aromatic and inviting.
Rub the Lamb: Generously apply the rub over the entire surface of the boneless leg of lamb. Ensure every inch is coated to infuse maximum flavor throughout the meat.
Secure the Lamb: Roll the lamb tightly and tie it with butcher’s twine. Place it on a roasting rack inside a prepared roasting pan, allowing air to circulate around the meat for even cooking.
Roast to Perfection: Place the pan in the oven and roast the lamb until a meat thermometer reads 135-140°F for medium-rare. This usually takes about 70 minutes, depending on the size of your roast.
Rest before Slicing: Once finished, remove the lamb from the oven and let it rest for 15 minutes. This step is essential for retaining juices; slice into ¼-inch pieces afterwards for tender, flavorful servings.
Optional: Garnish with additional rosemary sprigs or lemon slices for a beautiful presentation.
