  • 4 lb leg of lamb, bone-in
  • 5 cloves of garlic, minced
  • 2 tablespoons fresh rosemary, chopped
  • Zest and juice of 1 lemon
  • 2 tablespoons olive oil
  • Salt and black pepper to taste
  • 1 cup of chicken or beef broth


  1. Preheat your oven to 350°F (175°C).
  2. In a small bowl, combine the minced garlic, chopped rosemary, lemon zest and juice, olive oil, salt, and pepper to make a marinade.
  3. Rub the marinade all over the leg of lamb, ensuring it penetrates into all the nooks and crannies.
  4. Place the marinated lamb in a roasting pan. Pour the broth into the bottom of the pan.
  5. Roast in the preheated oven for about 20 minutes per pound, or until a meat thermometer reads 145°F (63°C) for medium-rare, or 160°F (71°C) for medium.
  6. Let the lamb rest for 15-20 minutes before carving to allow the juices to redistribute.

Ingredient Swaps

To cater to different dietary needs or ingredient availability, consider these swaps:

  • Lamb: If lamb isn’t to your liking, you could substitute it with a beef roast or even a whole chicken. Cooking times will need to be adjusted based on the type and size of the meat.
  • Olive Oil: If you prefer, avocado oil can replace olive oil for its neutral flavor and high smoke point.
  • Broth: The type of broth used can be switched based on personal preference. Chicken, beef, or vegetable broth would all work well.
