Step by Step Guide for Roasted Leg Of Lamb

Let’s dive into the process of making this succulent Roasted Leg Of Lamb. It’s a wonderful experience that brings out the chef in you. As you follow each step, you’ll find satisfaction in each small task that leads to the grand finale. Trust me, the end result is worth it!
Dry lamb: Remove the lamb from its packaging and place it on a clean cutting board. Pat the meat completely dry with paper towels to ensure a nice sear during roasting.
Bring to room temperature: Let the lamb sit at room temperature for about sixty minutes. This step helps it cook evenly. Meanwhile, you can prepare the pan and the wet rub.
Trim and score: Carefully trim excess fat from the lamb, leaving a thin layer. This is important for rendering fat during cooking. Next, score the lamb on both sides in a crosshatch pattern, making cuts about one inch apart and one-quarter to one-half inch deep.
Prepare pan and oven: Add the halved onions and garlic to the center of a large roasting pan, cut side up. Preheat your oven to three hundred twenty-five degrees Fahrenheit.
Season lamb: While the lamb is still on the cutting board, rub half of the wet rub all over one side, making sure to work it in well. Don’t apply the rub to the other side yet.
Add lamb to baking dish: Place the lamb in the pan, seasoned side down, resting on the garlic and onions. Now, rub the remaining wet rub all over the other side of the lamb.
Add broth and cover: Pour the broth and water around the lamb in the roasting pan. Cover the entire pan tightly with aluminum foil to keep the moisture in.
Slow roast: Bake the lamb at three hundred twenty-five degrees Fahrenheit for three hours. After three hours, check if the meat pulls easily from the bone using tongs. If it doesn’t, continue baking until it’s tender.
Rest: Once done, carefully remove the lamb from the oven. Generously spoon the pan juices over the top and transfer the lamb to a serving platter. Cover it loosely with foil while you make the gravy.
Separate fat: Add the pan juices to a gravy fat separator cup to skim off the fat easily. If you don’t have one, pour the juices into a large freezer bag, let the fat rise, and cut a small hole to drain the liquid.
Add broth to pan juices: Pour the pan juices into a measuring cup and add additional broth, only if needed, to equal two and a half cups.
Make roux: In a large saucepan, melt the butter over medium heat. Add the flour, whisking constantly for around two minutes to cook it through.
Add broth: Lower the heat and slowly incorporate the two and a half cups of pan juices and broth. Bring it to a gentle simmer, whisking until thickened to your desired consistency.
Season: Taste and adjust seasoning with salt and pepper. I recommend starting with beef bouillon for flavor before adding salt.
Serve: Remove the meat from the bone using tongs and serve it with the rich gravy poured over the top.
Things Worth Knowing
- Resting Time Matters: Allowing the lamb to rest after cooking helps redistribute the juices, making the meat more tender and flavorful.
- Scoring Technique: Scoring the lamb not only allows the rub to penetrate but also helps render fat during cooking, ensuring a crispy exterior.
- Use a Meat Thermometer: For perfect doneness, use a meat thermometer. Aim for an internal temperature of around 135 degrees Fahrenheit for medium-rare.
- Gravy Consistency: If your gravy is too thick, whisk in additional broth or water until you achieve your desired thickness.
- Storing Leftovers: Cool any leftovers quickly and store them in airtight containers in the fridge for up to five days.

Instructions
- Dry lamb: Remove lamb from the packaging and place it on a cutting board. Pat completely dry with paper towels.
- Bring to room temperature: Let lamb sit at room temperature for 60 minutes. Meanwhile, trim and score the lamb, prep the pan and make the wet rub and spread it over the lamb anytime in the 60-minute window (directions below).
- Trim and score: Trim excess fat (trim fat cap to about 1/8-inch). Score the lamb on both sides in a crosshatch/checkerboard pattern by running a sharp knife along the lamb in one direction, cuts about 1-inch apart, 1/4-1/2-inch deep, then the other direction.
- Prepare pan and oven: Add the onions and garlic to the center of a large roasting pan, cut side up. Preheat oven to 325 degrees F.
- Season lamb: While the lamb is still on the cutting board, rub half of the wet rub all over the side of the lamb with the fat cap, making sure to massage into all the nooks and crannies from scoring. Don’t add the wet rub to the other side yet.
- Add lamb to baking dish: Place the lamb, seasoned side down, in the pan so it’s propped up on the garlic and onions. Using your hands, rub the remaining wet rub all over the lamb.
- Add broth and cover: Pour broth and water around the lamb. Cover with foil.
- Slow roast: Bake at 325 degrees F for 3 hours. Check to see if the meat easily pulls from the bone with tongs after 3 hours. If not, continue to bake until tender.
- Rest: Remove lamb and generously spoon the pan juices over top. Transfer to serving platter and cover loosely with foil while you make the gravy.
- Separate fat: Add the pan juices (remove onions, and garlic) to a gravy fat separator cup to skim off the fat when poured. OR if you don’t have one, add the pan juices to a large freezer bag and allow the fat to separate to the top. Seal the bag and hold over a 3+ liquid measuring cup so that one bottom corner tip is facing down into the measuring cup like a spout. Make a small cut in this corner with scissors. The bottom liquid will flow through the cut, stop when you reach the fat.
- Add broth to pan juices: Add pan juices to a 3+ cup liquid measuring cup. Add additional broth, only if needed, to equal 2 ½ cups; set aside.
- Make roux: Melt butter in a large saucepan and melt over medium heat. Add the flour and cook for 2 minutes, whisking constantly.
- Add broth: Reduce heat to low and slowly whisk in the 2 ½ cups pan juices/broth. Bring to a simmer until thickened to desired consistency, whisking constantly. If it becomes too thick at any point, whisk in additional broth.
- Season: Taste and season with salt and pepper to taste. Instead of salt, I suggest starting with beef bouillon, ¼ teaspoon at a time, before salting to taste.
- Remove the meat from the bone with tongs and serve with gravy!
Notes
- Prep Ahead: This leg of lamb roast is ideal to prep ahead of time. Prepare the recipe through rubbing the wet rub all over the lamb. Loosely tent with foil for up to 24 hours. Remove the leg of lamb from the fridge 60 minutes before cooking and then proceed with the recipe.
- Storage: Leftover leg of lamb roast can be stored in an airtight container in the fridge for up to 5 days or in the freezer for up to 3 months.
- To reheat: To microwave, reheat portions for 60 seconds, followed by 10-second intervals as needed. To reheat in the oven, transfer pulled lamb to foil and enclose with a splash of broth or water. Bake at 350ºF for 8-10 minutes or until warmed through. To reheat in a skillet, add pulled lamb to a skillet with a splash of water or broth. Cover and cook on low until warmed through, stirring occasionally.
