Instructions
- Step 1: Preheat oven to 375°F. Pat dry 3 lbs bone-in lamb leg and make small incisions all over with a paring knife. Insert 6 sliced garlic cloves into the slits.
- Step 2: In a small bowl, whisk 1/4 cup olive oil, 1/4 cup fresh lemon juice, 3 tbsp chopped fresh oregano, 1 1/2 tsp salt, and 1 tsp black pepper.
- Step 3: Rub the lemon-oregano mixture evenly over the lamb leg, coating all sides. Place the lamb in a large roasting pan.
- Step 4: Scatter 2 lbs halved baby potatoes around the lamb and drizzle with any remaining marinade.
- Step 5: Roast uncovered for 1 hour 30 minutes to 1 hour 45 minutes, turning the potatoes once halfway through, until lamb reaches an internal temperature of 135°F for medium-rare and potatoes are golden and tender.
- Step 6: Remove from oven and tent with foil. Let rest for 15 minutes before carving and serving with the roasted potatoes.
