Bone-in or Boneless Leg of Lamb?
Bone-in leg of lamb is ideal for maximizing flavor and moisture, as the bone enhances richness and insulates the meat during smoking. While it requires longer cooking time and careful carving, its traditional presentation and juiciness make it a standout choice for special occasions. Personally, I choose bone-in leg of lamb for smoking.
However, boneless leg of lamb offers convenience, with even cooking, faster preparation, and simpler slicing. Though slightly less complex in flavor, it absorbs smoke well and benefits from brines or marinades to prevent drying. Perfect for efficient smoking without sacrificing tenderness, especially when time or ease is a priority.

How to Smoke Leg of Lamb?
Step 1: Prep the Lamb. Take the lamb out of the refrigerator at least an hour before you plan to start smoking. This allows it to come closer to room temperature, which helps it cook more evenly. Pat the lamb dry with paper towels.
Step 2: Make the Rub. In the large bowl, combine the olive oil, Dijon mustard, minced garlic, rosemary, thyme, smoked paprika, salt, pepper, onion powder, garlic powder, and cayenne pepper (if using). Mix well to form a paste.

Step 3: Rub It Good. Generously rub the paste all over the leg of lamb, making sure to get into every nook and cranny. Really massage it in there! I like to wear gloves for this part.
Step 4: Preheat the Smoker. Preheat your smoker to 225°F (107°C). This low and slow temperature is what makes the lamb so tender. Add your chosen wood chips according to your smoker's instructions.
Step 5: Start to Smoke Leg of Lamb. Place the rubbed leg of lamb directly on the smoker grate. Insert your wireless meat probe into the thickest part of the lamb, avoiding the bone.

Step 6: Monitor the Temperature. Smoke the lamb until it reaches an internal temperature of 135°F (57°C) for medium-rare, 145°F (63°C) for medium, or 155°F (68°C) for medium-well. This could take anywhere from 4-7 hours depending on the size of your lamb and your smoker. Be patient!
Step 7: The Stall is Real. Don't be surprised if the temperature stalls at some point. This is normal! Just keep the smoker temperature consistent and let it ride.
Step 8: Rest is Best. Once the lamb reaches your desired temperature, remove it from the smoker and wrap it tightly in aluminum foil or butcher paper. Let it rest for at least 30 minutes, or even up to an hour. This allows the juices to redistribute, resulting in a more tender and flavorful final product.
Step 9: Carve and Serve. After resting, unwrap the lamb and carve against the grain. Serve with your favorite sides, like roasted vegetables, mashed potatoes, or a fresh salad. I personally love pairing it with a bright and zesty chimichurri sauce.
