📝 About This Recipe

This recipe elevates the humble leg of lamb into a masterpiece of the pit, blending the rustic tradition of open-fire cooking with refined Mediterranean aromatics. The slow infusion of oak smoke mellows the lamb's natural gaminess, while a heavy crust of fresh herbs and garlic creates a savory, crackling exterior. It is a stunning centerpiece that promises a tender, blushing pink interior and a depth of flavor that only hours of low-and-slow heat can achieve.

🥗 Ingredients

The Meat

  • 6-7 lbs Bone-in Leg of Lamb (trimmed of excess fat cap but leaving a thin layer)

The Wet Rub (Herb Paste)

  • 1/4 cup Extra Virgin Olive Oil (high quality)
  • 8 cloves Garlic (minced into a paste)
  • 3 tablespoons Fresh Rosemary (finely chopped)
  • 2 tablespoons Fresh Thyme (finely chopped)
  • 2 tablespoons Dijon Mustard (acts as a binder)
  • 1 tablespoon Lemon Zest (from about 2 lemons)
  • 2 teaspoons Black Pepper (coarsely cracked)
  • 2 tablespoons Kosher Salt (adjust to preference)

The Basting Liquid

  • 1/2 cup Apple Cider Vinegar
  • 1/2 cup Beef Broth (low sodium)
  • 2 tablespoons Lemon Juice (freshly squeezed)

👨‍🍳 Instructions

  1. 1

    Remove the lamb from the refrigerator at least 1 hour before cooking to bring it to room temperature; this ensures even cooking throughout the muscle.

  2. 2

    Using a sharp paring knife, score the fat cap in a crosshatch pattern, being careful not to cut into the meat itself. This helps the fat render and the rub to penetrate.

  3. 3

    In a small bowl, whisk together the olive oil, minced garlic, rosemary, thyme, Dijon mustard, lemon zest, salt, and pepper until it forms a thick, fragrant paste.

  4. 4

    Slather the herb paste over the entire surface of the lamb, massaging it into the score marks and crevices. Let it sit for 30 minutes while you prep the smoker.

  5. 5

    Preheat your smoker to 250°F (121°C). Use a mild wood like Oak or Pecan; fruitwoods like Cherry also work beautifully with lamb.

  6. 6

    Place the lamb directly on the smoker grates, fat-side up. Insert a meat probe into the thickest part of the leg, avoiding the bone.

  7. 7

    In a spray bottle, combine the apple cider vinegar, beef broth, and lemon juice. This will be your spritz to keep the exterior moist.

  8. 8

    Smoke the lamb undisturbed for the first 90 minutes to allow the bark to set.

  9. 9

    After 90 minutes, lightly spritz the lamb with the vinegar mixture every 45 minutes until the internal temperature reaches 130°F (54°C) for medium-rare.

  10. 10

    Once the target temperature is reached, remove the lamb from the smoker. The carry-over heat will bring the final temp to about 135°F-140°F.

  11. 11

    Transfer the lamb to a cutting board and tent loosely with foil. Allow it to rest for at least 20-30 minutes; this is crucial for the juices to redistribute.

  12. 12

    Carve the lamb against the grain into thin slices and serve immediately while warm.

💡 Chef's Tips

Always use a digital meat thermometer; lamb can turn from succulent to dry very quickly if overcooked. If you prefer a more 'pulled' consistency, cook to 195°F, but for a leg of lamb, medium-rare (135°F) is the gold standard for flavor. Avoid heavy woods like Mesquite which can overwhelm the delicate flavor of the lamb. If the herb paste is too thick, add a teaspoon more of olive oil until it reaches a spreadable consistency. Save the bone for a rich lamb stock or to flavor a pot of white beans the next day.

🍽️ Serving Suggestions

Serve with a side of cooling Greek Tzatziki sauce to cut through the richness of the smoke. Pairs beautifully with roasted root vegetables or a bright lemon-herb orzo salad. For a wine pairing, choose a bold Cabernet Sauvignon or a peppery Syrah. Warm pita bread and a zesty Greek salad make this a complete Mediterranean feast. A side of mint chimichurri provides a fresh, modern twist on the classic mint jelly pairing.
