Ingredients
  

  • 1 leg of lamb - 4-5 lb
  • 4 tbsp olive oil
  • 6 cloves garlic - minced
  • 2 tbsp fresh rosemary - chopped
  • 1 tbsp fresh thyme
  • 1 tsp paprika
  • 1 tsp lemon zest
  • 2 tsp salt - or to taste
  • 1 tsp black pepper - or to taste
  • 1 cup beef or lamb broth
  • 1 lemon - cut into wedges

Method
 

Prepare Marinade
  1. Preheat your oven to 325°F (165°C).
  2. Pat the leg of lamb dry with paper towels.
  3. In a small bowl, whisk together the olive oil and minced garlic with rosemary, thyme, salt, pepper, paprika, and lemon zest.
Season the Leg of Lamb
  1. Massage the aromatic marinade all over the lamb, ensuring an even coat across the entire surface.
Slow Roast the Leg of Lamb
  1. Place the lamb in a roasting pan and pour the broth into the bottom of the pan.
  2. Roast uncovered for about 3 hours, or until the internal temperature reaches 135–145°F (57–63°C), depending on your desired level of doneness.
Rest the Meat
  1. Once removed from the oven, allow the lamb to rest for at least 10 minutes; this step is crucial for moisture retention before carving
Serve
