- 5-6 sprigs Fresh Rosemary: Rosemary’s woodsy, fragrant notes perfectly complement lamb and freshen every bite.

How to Make Easy Smoked Boneless Leg of Lamb Recipe
Step 1: Prepare the Lamb
Begin by preheating your smoker to 250ºF, or if you’re using an oven, aim for a steady low heat around the same temperature. Trim any excess fat from the leg of lamb but leave a nice thin layer on top—this fat will render beautifully during cooking and ensure juicy tenderness. Pat the meat dry with a paper towel to help the seasonings adhere.
Step 2: Infuse with Garlic and Seasonings
Take a sharp paring knife and puncture the lamb several dozen times about ¼ inch deep, creating little pockets for the garlic slices. Slide the fresh garlic cloves into these incisions—this step is where the magic happens by infusing every bite with garlic’s warm, savory notes. Then sprinkle kosher salt and pepper evenly all over the lamb, top and bottom. Tuck some fresh rosemary sprigs beneath the meat and gently wrap it back into its natural shape for an even cook.
Step 3: Apply the Marmite-Mustard Coating
Whisk together Marmite and whole grain mustard to form a thick, flavorful paste. This mixture not only adds incredible umami depth but also creates a beautiful glaze on the lamb. Spread it generously all over the top of the roast, ensuring every inch is well coated. Pour the white wine around the base of your roasting pan and scatter the remaining rosemary sprigs into the liquid—this will infuse the drippings with fragrant notes perfect for reducing into a sauce.
Step 4: Smoke the Lamb
Place the lamb in your smoker and let it cook low and slow. After the first hour, begin checking the internal temperature with a reliable meat thermometer. When it hits at least 145°F, it’s time to pull it out, but note that this process can take up to 3.5 hours depending on your smoker and the roast’s size. Make sure to baste the lamb regularly with the wine and pan juices—this keeps the meat incredibly moist and enhances that smoky crust.
Step 5: Rest and Prepare the Jus
Once out of the smoker, tent the lamb with foil and let it rest for at least 15 minutes on a cutting board. This crucial step allows the juices to redistribute, making your slices tender and juicy rather than dry. While resting, simmer the wine and drippings over medium-low heat until reduced to a rich jus that will add the perfect finishing touch.
Step 6: Slice and Serve
Using a sharp knife, slice the lamb thinly on the bias for the most tender mouthfuls. Serve with the reduced jus drizzled over the top and get ready to watch your guests come back for seconds of this stunning Easy Smoked Boneless Leg of Lamb Recipe.
How to Serve Easy Smoked Boneless Leg of Lamb Recipe
Garnishes
Fresh rosemary sprigs or a sprinkle of finely chopped parsley add a pop of color and a hint of fresh herbaceous flavor. A light drizzle of extra virgin olive oil or a sprinkle of flaky sea salt can elevate the presentation and texture even further.
Side Dishes
This lamb pairs wonderfully with classic roasted vegetables like carrots, potatoes, or parsnips tossed in olive oil and herbs. Creamy mashed potatoes or a crisp, peppery arugula salad with lemon vinaigrette also contrast the rich meat beautifully, balancing the plate.
Creative Ways to Present
Turn slices of lamb into elegant sliders with caramelized onions and a dollop of horseradish cream. Alternatively, serve alongside warm flatbread and a dollop of tzatziki for a fresh, Mediterranean-inspired spin that’s perfect for casual gatherings.
Make Ahead and Storage
Storing Leftovers
Wrap your leftover lamb tightly in foil or place it in an airtight container before refrigerating. The meat will stay fresh for up to 3 days, making it an easy next-day option for sandwiches or salads.
Freezing
For longer storage, slice the lamb and freeze portions in freezer-safe bags with excess air removed. This way, you preserve flavor and texture for up to 3 months, perfect for unexpected guests or quick meals later on.
Reheating
Gently reheat leftovers in a low oven around 300ºF, wrapped in foil to keep moisture locked in. Alternatively, warm slices in a covered skillet over low heat, adding a splash of broth or wine to keep the lamb juicy.
FAQs
Can I make this recipe without a smoker?
Absolutely! While smoking adds a wonderful smoky depth, you can easily roast the lamb in your oven at 250ºF. Use the same seasoning and basting method, and you’ll still get juicy, flavorful results.
How do I know when the lamb is perfectly cooked?
Use a meat thermometer and look for an internal temperature of at least 145°F for medium-rare. The lamb will continue to cook slightly while resting, so pulling it just before this temp ensures tender, juicy slices.
What if I can’t find Marmite? Can I substitute it?
Marmite adds a distinct umami flavor, but if unavailable, you can substitute with a reduced soy sauce or miso paste for a similar savory punch.
Can I prepare the lamb a day ahead?
Yes! You can prepare the garlic insertions and seasoning the night before, then refrigerate covered. This helps the flavors soak in even more deeply for an even tastier roast.
What sides would best complement this lamb?
Roasted root vegetables, creamy mashed potatoes, fresh green beans, or even a bright arugula salad all balance the richness of the lamb and complete the meal beautifully.

Seasoning and Marinade
- ¼ cup Marmite
- ¼ cup whole grain mustard
- Kosher salt, to taste
- Freshly ground black pepper, to taste
Liquids
- 1 ¼ cups white wine
Instructions
- Preheat the Smoker: Preheat your smoker to 250ºF to ensure it reaches the perfect low and slow temperature for smoking the lamb.
- Prepare the Lamb: Trim excess fat from the leg of lamb, leaving a thin layer on top to keep the meat moist while smoking. Pat the lamb dry using a paper towel to remove any surface moisture.
- Insert Garlic and Season: Use a paring knife to puncture several dozen holes about ¼ inch deep all over the leg. Slip slices of garlic into each hole to infuse the lamb with aromatic flavor. Sprinkle kosher salt and freshly ground black pepper evenly over the entire roast, both top and bottom.
- Add Rosemary: Insert a few sprigs of fresh rosemary under the roast before shaping it back to its original form to add herbal notes internally.
- Make the Marmite-Mustard Coating: In a bowl, mix together the Marmite and whole grain mustard until combined. Spread this mixture generously all over the top of the lamb to form a flavorful crust during smoking.
- Prepare the Roasting Dish: Pour the white wine into the base of your roasting pan or smoker drip pan. Sprinkle the last few rosemary sprigs into the wine to further enrich the flavor.
- Smoke the Lamb: Place the lamb in the preheated smoker and smoke for about 3 to 3.5 hours total. After the first hour, begin checking the internal temperature regularly using a meat thermometer. Continue to baste the roast with the wine and drippings each time you open the smoker lid. The lamb is done when it reaches an internal temperature of at least 145ºF for medium rare.
- Rest the Roast: Remove the lamb from the smoker and tent it loosely with foil. Allow it to rest on a cutting board for at least 15 minutes to redistribute the juices and enhance tenderness.
- Make the Jus and Serve: While the lamb rests, pour the wine and drippings into a saucepan and simmer over medium-low heat until reduced to a rich jus. Thinly slice the lamb on the bias and serve with the reduced jus poured over. Enjoy your delicious smoked leg of lamb!
