A leg of lamb is one of the most impressive and flavourful cuts of meat, making it a perfect centrepiece for family gatherings, holiday feasts, and Sunday roasts. Whether you’re roasting, slow-cooking, or grilling, mastering the art of cooking lamb will take your culinary skills to the next level. In this guide, we’ll explore different ways to prepare a leg of lamb, seasoning ideas, and tips to ensure tender, juicy results every time.

What makes Leg of Lamb so special?

Leg of lamb is prized for its rich flavour, tender texture, and versatility. It’s a leaner cut compared to lamb shoulder, making it ideal for roasting, while still offering enough marbling to stay juicy and flavourful.

  • Bone-in vs. Boneless: A bone-in leg retains more flavour and moisture, while a boneless leg is easier to carve and can be stuffed for added flavour.

  • Whole vs. Butterflied: A whole leg is best for roasting, while a butterflied leg is great for grilling and marinating.

Roast Lamb Leg With Rosemary & Garlic Recipe by Sonia
This is our traditional Easter meal, a leg of lamb stuffed with fresh rosemary from the garden and thick slices of garlic. It’s such a treat as we don’t eat lamb often. Choose woodier stalks of rosemary as they are easier to push into the meat.

How to Prepare a Leg of Lamb for Cooking

  • Choosing the Right Cut
    Look for deep pink or red meat with creamy white fat. Avoid cuts with excessive gristle or a strong smell.
  • Bringing to Room Temperature
    Take the lamb out of the fridge at least 1 hour before cooking to ensure even cooking.
  • Seasoning & Marinades
    Lamb pairs well with a variety of seasonings. Here are some flavorful ideas:
    Classic Garlic & Rosemary – A timeless combination for a traditional roast.
    Mediterranean Style – Olive oil, lemon, oregano, and garlic for a fresh, herby flavor.
    Middle Eastern Spices – Cumin, coriander, cinnamon, and sumac for a warm, aromatic taste.
    Spicy Harissa – A North African-inspired marinade with harissa paste, honey, and lemon.

Cooking Methods: What’s the best way to cook a leg of lamb?

Roasting is the most popular way to cook a leg of lamb. Here’s how to do it:

  1. Preheat the oven to 220°C (425°F).
  2. Score the fat to help the flavors penetrate.
  3. Rub with olive oil and spices, then place in a roasting pan.
  4. Roast for 20 minutes at high heat, then lower to 180°C (350°F).
  5. Cook to your preferred doneness:
    Rare: 50°C (125°F), ~15 min per pound
    Medium-rare: 55°C (130°F), ~20 min per pound
    Medium: 60°C (140°F), ~25 min per pound
    Well-done: 70°C (160°F), ~30 min per pound
💡 Rest the meat for at least 15 minutes before carving to retain juices.
