Ingredients

Instructions

  1. Step 1: Preheat the oven to 375°F. In a small bowl, mix 4 tbsp olive oil, 2 tbsp chopped fresh rosemary, 6 minced garlic cloves, 2 tsp salt, and 1 tsp black pepper. Rub this herb mixture all over a 3 lb bone-in lamb leg.
  2. Step 2: Place the lamb in a large roasting pan. Arrange 2 lbs peeled and 1-inch chunked russet potatoes around the lamb. Drizzle potatoes with 3 tbsp lemon juice and sprinkle with 1 tbsp chopped fresh oregano.
  3. Step 3: Pour 1 cup water into the pan to help keep the potatoes moist. Roast uncovered for 1 hour and 30 minutes, basting the lamb and stirring potatoes halfway through, until lamb registers 135°F for medium-rare and potatoes are golden and tender.
  4. Step 4: Remove from oven and let lamb rest for 15 minutes before slicing. Serve slices alongside the lemon garlic potatoes.
