Smoked Leg of Lamb with Garlic, Rosemary and Mint Yogurt Sauce
A celebratory smoked leg of lamb rubbed with garlic and rosemary, smoked low and slow to a tender medium-rare and finished for a crisp crust. Served with a bright mint-yogurt sauce that cuts the richness and makes this roast perfect for holidays and special gatherings.
Ingredient Spotlight
Hardwood smoking chips (oak or hickory), soaked 30 minutes
Small pieces of hardwood used to generate smoke when grilling or barbecuing; soaking them briefly slows how fast they burn and helps produce steady smoke. This technique is particularly associated with American barbecue and smoking traditions; oak gives a medium, versatile smoke while hickory is stronger and a bit bacon-like. Find them at barbecue/outdoor stores, many supermarkets, or online; substitutes include larger wood chunks or pellets for a smoker, or a small dash of liquid smoke if you cannot access real wood.
Jake's note
"This smoked leg of lamb is great for holiday feasts or any time you want an impressive centerpiece with hands-off cooking. The mint-yogurt sauce is quick to make and refreshes each rich, smoky bite."
Smoked Leg of Lamb with Garlic, Rosemary and Mint Yogurt Sauce
Smoked leg of lamb is the kind of roast that fills a backyard with scent and a table with stories. This version leans into the classics—garlic and rosemary forming a fragrant crust—while the slow smoke gently tames lamb’s natural richness and keeps the interior tender and rosy. Smoking at low temperature develops a subtle woody edge from oak or hickory without overpowering the aromatics; finishing at high heat gives the outside a crisp, savory crust that contrasts perfectly with a plush medium-rare center. The mint-yogurt sauce is essential: its bright acid and cooling texture cut through the fat and lift each slice, turning each bite into a balanced mouthful.
This recipe is built for celebrations and cooks who like a bit of theatre: there’s a reassuringly long unattended smoking window followed by a rapid, gratifying finishing step. Use the bone-in leg for flavor and easier carving, and don’t rush the rest — carryover heat will nudge the roast to the ideal doneness. Whether you’re serving a formal holiday plate or a relaxed summer feast, this lamb rewards attention with bold, clear flavors and a dinner-table moment.

Tips from the kitchen
Make a concentrated paste
Mince the garlic very fine and mash with the rosemary and salt to form a paste so it adheres and flavors the meat instead of falling off during smoking.
Probe placement matters
Insert the thermometer into the thickest part of the leg, avoiding bone, to get an accurate read; bone conducts heat and will give a falsely high temperature.
Choose your wood wisely
Oak gives a balanced smoke that complements lamb, while hickory adds a stronger, bacon-like note—use oak for subtlety and hickory if you want a pronounced smoky edge.
Finish hot for crust
Don’t skip the high-heat finish: the contrast between low-and-slow interior and a quick blast at 400–425°F creates the savory crust that makes each slice appealing.
Temper the sauce
Make the mint-yogurt sauce just before serving and taste for acidity; a splash more lemon brightens leftover richness and a drizzle of olive oil adds silkiness.
Variations & substitutions
Boneless leg option
Use a boneless leg trimmed and tied—reduce smoking time slightly and monitor temperature closely, as boneless roasts cook a bit faster and are easier to carve thinly.
Dairy-free sauce
Swap Greek yogurt for a silken tofu or coconut yogurt base, add lemon and mint, and thin with a little olive oil for a cooling, dairy-free accompaniment.
Middle Eastern twist
Add ground cumin and coriander to the garlic-rosemary rub and finish the sauce with a pinch of ground sumac or a little pomegranate molasses for bright, regional flavor.
Herb-forward variation
Replace half the rosemary with chopped thyme and oregano, and fold parsley into the mint-yogurt for a greener, more Mediterranean sauce.
Storage & make-ahead
Leftover sliced lamb will keep in an airtight container in the fridge for up to 3 days; reserve any pan juices separately to spoon over when reheating. Reheat gently in a low oven (250–275°F) covered with foil for 10–15 minutes, or warm slices briefly in a skillet with a splash of stock to avoid drying out. The mint-yogurt sauce will keep 2–3 days refrigerated; stir before serving, and add a little water or olive oil if it tightens up.
What to serve with it
Serve the lamb with simple, textured sides that can stand up to its richness: roasted baby potatoes tossed with rosemary, charred spring vegetables, or a lemony couscous or freekeh salad. A crisp green salad with radish and cucumber echoes the mint-yogurt sauce, while toasted pita or lavash invites guests to make small sandwiches. For drinks, a medium-bodied red like Rioja or a peppery Syrah complements the smoke and herbs, and a dry Riesling or sparkling water is refreshing with the sauce.
Frequently asked questions
What internal temperature should I aim for?
Smoke the leg to about 125°F for a rosy medium-rare after resting; after the high-heat finish remove at 135°F so carryover brings it to around 140°F depending on your roast and resting time.
How long will smoking take?
At 225°F expect roughly 3–4 hours for a 4.5 lb bone-in leg, but times vary with meat size, smoker behavior, and ambient temperature—rely on the probe thermometer, not the clock.
Can I brine or marinate beforehand?
Dry-brining with the kosher salt in the rub overnight deepens flavor and improves texture; avoid heavy wet marinades that mask the smoke and can prevent a crisp crust.
Is it okay to finish in an oven instead of the smoker?
Yes—transfer to a 425°F oven or a screaming-hot grill to develop the crust; the key is a quick, high-heat blast so the interior stays medium-rare while the exterior browns.
Can I make the mint-yogurt sauce ahead?
You can make the sauce up to 24 hours ahead; refrigerate and bring it up to cool-room temperature before serving, then taste and adjust lemon and salt as the flavors can mellow overnight.
