Ingredients
Scale
- Leg of Lamb:
- 1 (5-7 pound) Bone-in Leg of Lamb: The star of the show! Opt for a bone-in leg of lamb as it imparts more flavor and helps retain moisture during roasting. A weight range of 5 to 7 pounds will comfortably serve 6-8 people. You can find leg of lamb at most butcher shops and well-stocked grocery stores. Consider asking your butcher to trim any excess fat cap, leaving a thin layer for rendering and flavor.
- Pro-Tip: For even cooking, ensure your leg of lamb is roughly the same thickness throughout. If one end is significantly thicker, you may need to butterfly it slightly or adjust cooking time accordingly.
- Marinade Magic: The marinade is what truly elevates this dish from simple roasted lamb to a Mediterranean masterpiece. It tenderizes the meat, infuses it with vibrant flavors, and creates a delicious crust during roasting.
- 1/2 cup Extra Virgin Olive Oil: The cornerstone of Mediterranean cuisine, extra virgin olive oil provides richness, flavor, and healthy fats. Choose a good quality olive oil for the best taste.
- 1/4 cup Fresh Lemon Juice: Brightens the marinade, tenderizes the lamb, and adds a signature Mediterranean tang. Freshly squeezed lemon juice is essential for optimal flavor.
- 6–8 Cloves Garlic, minced: Garlic is indispensable in Mediterranean cooking, providing pungent aroma and savory depth. Freshly minced garlic is always preferable to pre-minced for its superior flavor.
- 1/4 cup Fresh Rosemary, chopped: Rosemary brings a distinctive piney, earthy, and aromatic note that perfectly complements lamb. Fresh rosemary is highly recommended, but in a pinch, you can use dried rosemary (use about 1 tablespoon, as dried herbs are more concentrated).
- 2 tablespoons Fresh Oregano, chopped: Oregano adds a slightly peppery, robust flavor that is quintessential to Mediterranean dishes. Fresh oregano is best, but 2 teaspoons of dried oregano can be substituted if needed.
- 1 tablespoon Dijon Mustard: Dijon mustard adds a subtle tang and helps emulsify the marinade, ensuring it coats the lamb evenly.
- 1 teaspoon Salt: Essential for seasoning and enhancing the flavors of all the ingredients. Use kosher salt or sea salt for best results.
- 1 teaspoon Black Pepper, freshly ground: Freshly ground black pepper provides a pungent bite and complements the other spices beautifully.
- Vegetables for Roasting (Optional but Highly Recommended): Roasting vegetables alongside the lamb not only adds flavor to the lamb drippings but also creates a complete and satisfying meal.
- 1 pound Small Potatoes, halved or quartered: Potatoes roast beautifully with the lamb, absorbing the flavorful drippings. Yukon Gold or red potatoes work particularly well.
- 1 pound Carrots, cut into 2-inch pieces: Carrots add sweetness and color to the roast.
- 1 Red Onion, cut into wedges: Red onion caramelizes beautifully during roasting, adding a sweet and savory element.
- 1 Bell Pepper (any color), cut into chunks: Bell peppers add sweetness and a vibrant pop of color. Red or yellow bell peppers are particularly flavorful when roasted.
- Optional additions: Feel free to add other Mediterranean-inspired vegetables like zucchini, eggplant, cherry tomatoes, or artichoke hearts.
- Garnish (Optional): A fresh garnish adds a final touch of freshness and visual appeal.
- Fresh Parsley, chopped: Parsley adds a bright, herbaceous note and a pop of green color.
- Lemon wedges: Extra lemon wedges for squeezing over the lamb just before serving enhance the bright, Mediterranean flavors.
Instructions
- Prepare the Marinade (At least 2 hours, ideally overnight):
- In a large bowl, whisk together the extra virgin olive oil, lemon juice, minced garlic, chopped rosemary, chopped oregano, Dijon mustard, salt, and freshly ground black pepper. Ensure all ingredients are well combined to create a homogenous and flavorful marinade.
- Taste and Adjust: Taste the marinade and adjust seasonings as needed. You may want to add a pinch more salt, pepper, or lemon juice to suit your preference. Remember that the marinade will infuse the lamb with flavor, so it should be well-seasoned.
- Marinate the Lamb:
- Place the leg of lamb in a large resealable plastic bag or a large, non-reactive dish (glass or ceramic is ideal).
- Pour the marinade over the lamb, ensuring it coats all sides of the meat. If using a plastic bag, seal it tightly and massage the marinade into the lamb. If using a dish, turn the lamb to coat it evenly.
- Marinate Time: Marinate the lamb in the refrigerator for at least 2 hours, and ideally overnight, or up to 24 hours for maximum flavor penetration and tenderization. The longer the lamb marinates, the more flavorful and tender it will become. If marinating overnight, turn the lamb occasionally to ensure even marination.
- Preheat Oven and Prepare Vegetables (30 minutes before roasting):
- Preheat your oven to 325°F (160°C). Lower temperature roasting ensures tender and juicy lamb.
- While the oven preheats, prepare your vegetables (if using). Wash, peel (if necessary), and cut the potatoes, carrots, red onion, and bell pepper into appropriately sized pieces, as described in the ingredient section.
- Toss Vegetables with Olive Oil and Seasoning: In a separate bowl, toss the prepared vegetables with about 2 tablespoons of olive oil, salt, and pepper. You can also add a sprinkle of dried oregano or rosemary to the vegetables for extra flavor.
- Roast the Lamb and Vegetables:
- Remove the lamb from the marinade and place it in a large roasting pan. Reserve the marinade – do not discard it!
- Arrange the vegetables around the leg of lamb in the roasting pan. Spread them in a single layer to ensure even roasting.
- Add Marinade to Roasting Pan: Pour the reserved marinade over the lamb and vegetables. This will add moisture and flavor during roasting.
- Roasting Time: Roast in the preheated oven for approximately 20-25 minutes per pound for medium-rare, or 25-30 minutes per pound for medium. Use a meat thermometer to ensure accurate doneness.
- For Medium-Rare: Aim for an internal temperature of 135°F (57°C).
- For Medium: Aim for an internal temperature of 145°F (63°C).
- For Medium-Well: Aim for an internal temperature of 150°F (66°C).
- For Well-Done: Aim for an internal temperature of 160°F (71°C). (Note: Lamb is best enjoyed medium-rare or medium to maintain tenderness).
- Basting (Optional but Recommended): Baste the lamb with the pan juices every 30-45 minutes during roasting. This helps keep the lamb moist and flavorful and encourages browning.
- Rest the Lamb (Crucial Step):
- Once the lamb reaches your desired internal temperature, remove it from the oven.
- Transfer the leg of lamb to a cutting board and loosely tent it with aluminum foil.
- Resting Time: Let the lamb rest for at least 15-20 minutes before carving. Resting allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful roast. Do not skip this crucial step! The internal temperature will continue to rise slightly during resting.
- While the lamb rests, continue roasting the vegetables in the oven if they are not yet tender and slightly caramelized.
- Carve and Serve:
- After resting, carve the leg of lamb against the grain into slices. For easier carving, you can separate the shank bone (the thinner end) from the main leg bone before slicing.
- Arrange the sliced lamb on a serving platter, surrounded by the roasted vegetables.
- Garnish: Garnish with fresh chopped parsley and serve with lemon wedges for squeezing over the lamb.
- Serve Immediately: Serve immediately while the lamb is hot and juicy.
