How to Make Slow Roasted Boneless Leg of Lamb
-
Combine the marinade by mixing minced garlic, fresh herbs, ground spices, lemon zest, lemon juice, olive oil, and Dijon mustard (if using) in a bowl until you form a thick paste. This aromatic blend will infuse your lamb with deep flavors.
-
Prepare the lamb by laying it fat side down on a clean surface. Rub half the marinade inside the meat, then roll the lamb tightly and secure it with kitchen twine or butcher’s string. Rub the remaining marinade over the exterior of the lamb for a full flavor boost.
-
Marinate for optimal flavor. Place the seasoned lamb in the refrigerator for 4 to 12 hours, ideally overnight. Don’t forget to let it sit at room temperature for about an hour before cooking—this ensures even cooking!
-
Preheat your oven to 300°F (150°C). While it heats, scatter chopped onions, carrots, and celery in a roasting pan and pour in the low-sodium broth or water to create a flavorful base for the lamb.
-
Position the lamb on a roasting rack set above the vegetable bed. Drizzle a little olive oil over the lamb to keep it moist. Roast this beauty for about 3 to 3½ hours or until the internal temperature reaches 145°F (63°C) for perfect doneness.
-
Baste the lamb with pan juices every 30 minutes to keep it juicy! For a beautifully browned crust, increase the oven temperature to 425°F (220°C) in the last 15 minutes of roasting.
-
Rest the lamb after removing it from the oven. Tent it with foil and let it rest for about 20 to 30 minutes before slicing. This delicious step allows the juices to redistribute, ensuring tender slices with every cut! Strain the pan juices for a tasty sauce if desired.
Optional: Serve with a sprinkle of fresh herbs for a beautiful garnish.

Very! To keep your leftover slow roasted boneless leg of lamb fresh, store it in an airtight container in the refrigerator for up to 4 days. Let the meat cool down to room temperature before sealing to keep its juicy texture intact. If you want to keep it longer, you can freeze portions—just wrap them tightly in foil and place them in a freezer-safe container, where they’ll last up to 2 months.
Can I freeze the slow roasted leg of lamb? If so, how?
