Ingredients
- 3 lbs bone-in leg of lamb
- 1/4 cup fresh lemon juice
- 1/4 cup extra virgin olive oil
- 4 cloves garlic cloves, minced
- 2 tbsp dried oregano
- 1 tbsp sea salt
- 1 tsp freshly ground black pepper
- 1/2 cup water
Instructions
- Step 1: In a mixing bowl, combine 1/4 cup fresh lemon juice, 1/4 cup extra virgin olive oil, 4 minced garlic cloves, 2 tbsp dried oregano, 1 tbsp sea salt, and 1 tsp freshly ground black pepper. Whisk until well blended.
- Step 2: Place the 3 lbs bone-in leg of lamb in a large resealable bag or shallow dish and pour the marinade over it, ensuring the meat is well coated. Seal or cover and refrigerate for at least 4 hours, preferably overnight.
- Step 3: Preheat the oven to 325°F (160°C). Remove the lamb from the marinade and place it on a roasting rack inside a roasting pan. Pour 1/2 cup water into the pan to keep the meat moist.
- Step 4: Roast the lamb for approximately 1 hour 45 minutes to 2 hours, basting every 30 minutes with the pan juices, until an internal temperature of 135°F (57°C) for medium-rare is reached.
- Step 5: Remove the lamb from the oven, tent loosely with foil, and let rest for 15 minutes before slicing to allow the juices to redistribute.
