Difficulty Level
Medium: Ideal for cooks comfortable handling roasting and marinating techniques but approachable with clear guidance.
Ingredients
- 1 (5 to 6 pounds) bone-in leg of lamb, trimmed of excess fat
- 4 cloves garlic, thinly sliced
- 2 tablespoons fresh rosemary, finely chopped
- 2 tablespoons fresh thyme, chopped
- 1/4 cup extra virgin olive oil
- 1/4 cup lemon juice (freshly squeezed)
- 1 teaspoon Dijon mustard
- 1 tablespoon kosher salt
- 1 teaspoon freshly ground black pepper
- 1 cup dry white wine or chicken broth (for roasting pan)
- 2 medium onions, quartered
Instructions
- Selecting the Cut: Choose a well-marbled leg of lamb with an even layer of fat for flavor and moisture. Look for a radiant, pinkish-red color and firm texture to ensure freshness and tenderness.
- Preparing the Marinade: In a bowl, combine olive oil, lemon juice, mustard, rosemary, thyme, garlic, salt, and pepper. Whisk thoroughly to bind the flavors.
- marinate the Lamb: Using a sharp knife, pierce the lamb’s surface and insert garlic slices throughout for aromatic bursts. Place the lamb in a large resealable bag or shallow dish, pour the marinade over the meat, and massage gently to coat evenly.Cover and refrigerate for 8 to 12 hours to deeply infuse flavors.
- Bring To room Temperature: Remove the lamb from the fridge 1 hour before roasting to ensure even cooking and reduce chilling on the inside.
- Preheat the Oven: Set your oven to 375°F (190°C) for a balance of browning and gentle cooking.
- Prepare the Roasting Pan: Scatter quartered onions in the base of a sturdy roasting tray and pour in the white wine or broth to create a flavorful steaming habitat.
- Roast the Lamb: Place the lamb on a rack above the onions fat side up. Roast uncovered to allow the fat to baste the meat naturally. Aim for about 15-18 minutes per pound for medium-rare (internal temp 135°F before resting). Baste occasionally with pan juices for extra juiciness.
- Resting: Transfer the lamb to a cutting board, loosely tent with foil, and rest for 15 minutes. This essential step lets the juices redistribute, ensuring every slice is moist and tender.
- Carving and Serving: Carve against the grain into thick, juicy slices. Spoon pan juices and softened onions over the meat or use as a base for a rich gravy.
Chef’s Notes: Tips for Success
- Marinating Mastery: Don’t rush the marinade-overnight soaking truly unlocks the depth of flavor and tenderness.
- herb Variations: Add mint or oregano for a Mediterranean twist or a hint of warm spices like smoked paprika and cumin for smoky complexity.
- Resting Importance: Skipping the resting phase results in dry meat; always rest as instructed for peak juiciness.
- Make-Ahead Tip: Marinate the lamb up to 24 hours in advance and bring to room temperature before cooking for convenience without compromising quality.
- thermometer Tip: Use an instant-read meat thermometer to monitor doneness precisely-aim for 130-135°F for medium-rare,140-145°F for medium.
- Substitution: Boneless leg works but reduce roasting time and monitor closely as it cooks faster.
