Ingredients

Scale
  • 1 (5-6 lb) leg of lamb, bone-in
  • 4 cloves garlic, minced
  • 2 tbsp fresh rosemary, chopped
  • 2 tbsp fresh thyme, chopped
  • 1 tbsp Dijon mustard
  • 2 tbsp olive oil
  • 1 tsp salt
  • 1 tsp black pepper
  • 1 lb baby potatoes, halved
  • 2 large carrots, chopped
  • 1 onion, quartered
  • 1 cup beef or vegetable broth

Instructions

  1. Preheat your oven to 375°F (190°C). Pat the leg of lamb dry with paper towels. Mix garlic, rosemary, thyme, Dijon mustard, olive oil, salt, and pepper in a bowl. Rub this mixture all over the lamb.
  2. Place halved baby potatoes, chopped carrots, and quartered onion in a roasting pan. Drizzle with olive oil and season with salt and pepper. Place the seasoned lamb on top, fat side up.
  3. Pour broth into the roasting pan. Roast for about 1 hour and 30 minutes, basting every 30 minutes, until the internal temperature reaches 145°F (63°C) for medium-rare.
  4. Remove from oven and let rest for 15 minutes before carving. Serve with roasted vegetables and pan juices.

Notes

  • Bring the lamb to room temperature before roasting for even cooking.
  • Use fresh herbs for the best flavor—rosemary and thyme are classic choices.
  • Let the lamb rest after roasting to keep it juicy.
  • Save the pan juices to make a delicious gravy.
