Prepare this perfect Roasted Boneless Lamb with Red Wine Pan Sauce for any special meal!
With Easter just a few weeks away – it’s time to start planning your holiday dinner menu. We’re already looking forward to our Easter dinner, and this Roasted Boneless Lamb with Red Wine Pan Sauce is going to be the star of the meal.
Roasting a boneless leg of lamb is a traditional main dish option for any Easter holiday meal. Our Roasted Boneless Lamb recipe is especially flavorful thanks to a filling made with garlic, rosemary, parsley, thyme and olive oil. Then a rub of lemon juice, rosemary and Dijon mustard is spread over the lamb before roasting – resulting in a delicious, savory crust once the leg of lamb comes out of the oven.
We followed the same low-and-slow roasting method we use in our perfect prime rib recipe that everyone raves about, and the very same roasting technique ensures perfectly cooked, tender lamb that comes out of the oven when an internal temperature of 135 degrees F is reached. (If you don’t have one already, you really should invest in a probe thermometer that can be used when roasting any kind of meat and poultry in the oven!)
Our roasted boneless lamb is then served with a rich and delicious red wine pan sauce that perfectly complements the flavor of the roasted meat.
You’ll prepare the sauce while the lamb rests after it comes out of the oven. You’ll blend the pan drippings with beef stock and a robust red wine (we used Cabernet Sauvignon) plus fresh rosemary, thyme , shallots and butter and reduce until slightly thickened – creating a simple, delicious pan sauce.
Serve this Roasted Boneless Lamb with Red Wine Pan Sauce on a platter as shown below with green beans and roasted potatoes. (Be sure to check back again soon because we will be sharing both recipes for the green beans and herbed potatoes you see below.)

To prepare the Roasted Lamb
- 5–6 pound boneless, tied leg of lamb
- Kosher salt
- Freshly ground black pepper
- Zest from 2 lemons
- 5 garlic cloves minced (2 1/2 tablespoons)
- ½ cup chopped mixed fresh herbs (equal amounts of Italian parsley, rosemary and thyme)
- 4 tablespoons extra virgin olive oil, divided
- Juice from one lemon
- 2 tablespoons Dijon mustard
- 2 tablespoons chopped fresh rosemary
To prepare the Red Wine Pan sauce
- 1 tablespoon extra virgin olive oil
- ¼ cup minced shallots
- 1 cup red wine
- 1 quart chicken or beef stock (or half of each)
- 2 fresh rosemary sprigs, about 4–6 inches in length
- 8 fresh thyme sprigs
- 3 Tablespoons butter
- Kosher salt
- Freshly ground black pepper
To prepare the Roasted lamb
- Preheat oven to 325 degrees F.
- Remove netting from roast and discard. Open up lamb, cut side up on your cutting board and sprinkle generously with salt and pepper.
- In a small bowl, mix together zest, garlic, herbs and 2 tablespoons of olive oil. Using your hands, spread all over inside cavity of lamb.
- Fold lamb back into a roast and place on board fat side up. Using good butcher’s twine, wrap and tie four or five side wraps down the length of the roast and two more end to end.
- Place fat side up in a baking dish.
- In a small bowl, mix lemon juice, mustard, rosemary and remaining olive oil. Mix to combine and spread all over the top of the roast.
- Place probe thermometer into the thickest part of the roast and set temperature to alarm at 125 degrees F. Place roast in center rack of oven.
- Roast at 325 degrees F for about two hours or until internal temperature reaches 125 degrees F.
- Increase oven temperature to 450 degrees F and roast for about 15 additional minutes or until internal temperature reaches 135 degrees F and outside of roast is slightly charred.
- Remove from oven, place the roast on a platter and loosely cover with foil. However, leave probe thermometer in so that juices don’t leak out. Let the roast rest at least 20 minutes before removing probe and slicing.
- Make pan sauce while roast is resting.
- Remove twine and slice. Serve with pan sauce, see below.
To prepare the Red Wine Pan Sauce
- In a small sauce pan over medium heat, sauté shallots in olive oil 2-3 minutes or until tender. Set aside.
- In the pan that was used to roast the lamb, drain off and discard all lamb fat leaving brown bits on bottom and place over a medium burner. (I poured fat off into cup and once it settled, I discarded fat that floated to top and put the liquid and sediment from the bottom of the cup back into the pan) Add red wine and cooked shallots and scrape any bits from the bottom of the pan. Reduce wine mixture until almost all wine has evaporated.
- Add in stock and fresh herbs and any juice that has accumulated on platter. Reduce by at least half or more. (I reduced down to about a cup and a quarter).
- Off heat, add in butter and stir into sauce. Season with additional salt and pepper if needed. Strain sauce through a fine mesh strainer and into a gravy boat and discard solids. The sauce is not thick like gravy but just slightly thick. If the sauce is too intense, simply dilute with a little water.
