Ingredients

Instructions

  1. Step 1: Preheat your oven to 325°F (160°C). Using a sharp knife, pierce 3 lbs lamb shoulder all over and insert 8 sliced garlic cloves into the slits.
  2. Step 2: In a small bowl, mix 1/4 cup olive oil, 1/4 cup fresh lemon juice, 2 tbsp dried oregano, 2 tbsp chopped fresh rosemary, 2 tsp salt, and 1 tsp black pepper. Rub this marinade thoroughly over the lamb.
  3. Step 3: Place the lamb into a large roasting pan on top of 1 sliced large onion, pour in 1 cup water around the meat, and cover tightly with foil.
  4. Step 4: Slow roast in the oven for 3 to 3.5 hours until the meat is tender and falling off the bone.
  5. Step 5: Remove foil, sprinkle 4 oz crumbled feta cheese over the lamb, and roast uncovered for an additional 15 minutes to melt the cheese slightly.
  6. Step 6: Let rest for 10 minutes before serving with the roasted onions and pan juices.
