When it comes to creating a fabulous and unforgettable meal, few dishes can rival the classic roast leg of New Zealand lamb. Known for its tenderness and deep, rich flavour, this Kiwi favourite is a staple for Christmas, Easter, Sunday dinner, or any special occasion. At The Aussie Butcher, we pride ourselves on offering premium-quality New Zealand lamb, so you can trust that your roast leg will deliver delicious results every time.
Why NZ Lamb Is the Best for Roasting
Lamb leg from New Zealand is globally recognised for its clean, natural taste and tender texture. This is thanks to our pristine environment and traditional farming practices that focus on raising healthy, grass-fed lamb. The natural flavour of a whole leg of lamb from NZ is enhanced when roasted, making it a centrepiece that truly celebrates our country’s proud meat heritage.
Choosing the Perfect Lamb Leg
When selecting your leg of lamb, opt for a bone-in cut for added flavour and moisture. Look for a lamb leg that has a healthy pink hue and a layer of fat to keep the meat juicy during cooking. At The Aussie Butcher, our butchers are happy to help you choose the best cut for your needs, whether you’re cooking for two or feeding a crowd.
Preparing the Roast Leg of Lamb
Begin by preheating your oven to roughly 180°C (350°F). Pat dry the lamb with paper towels and place it on a rack in a roasting dish. Prepare a rub using olive oil, crushed garlic, salt, pepper, and finely chopped fresh rosemary. For added flavour, insert garlic slivers and small rosemary sprigs directly into small incisions cut into the meat.
Drizzle the oil over the lamb and season generously. This simple yet aromatic paste helps create a golden crust and keeps the meat moist throughout the cooking time.
Roasting the Leg of Lamb to Perfection
Place your roast leg in the preheated oven and roast for approximately 25 minutes per 500g for medium rare. Always use a meat thermometer to determine the internal temperature:
- Medium Rare: 60°C
- Medium: 65°C
- Well Done: 70°C
Once the desired temperature is reached, remove the roasted meat from the oven and cover it loosely with foil. Let it rest for 15–20 minutes. This allows the meat’s natural juices to redistribute, resulting in a juicy, more tender slice.
Adding Flavour with Glazes and Marinades
To elevate your roast lamb, try brushing on a glaze made of honey, olive oil, fresh rosemary, and lemon juice during the last 15 minutes of cooking. Alternatively, a red wine and garlic marinade left overnight in the fridge will infuse the meat with deep, savoury notes.
Making a Rich Gravy from Pan Juices
While your lamb rests, place the roasting pan over the stove on medium heat. Skim off excess fat, then sprinkle in a tablespoon of plain or corn flour and stir to create a smooth paste. Slowly add wine, water, or stock, scraping up all the delicious golden bits stuck to the pan. Whisk until smooth and slightly thickened. Season with salt and pepper to taste, then strain for a rich gravy.
Serving and Enjoying Your Roast Leg of Lamb
Carve the leg against the grain into thin slices and arrange on a pre-warmed serving platter. Pair your roast lamb with classic sides like roasted carrots, garlic mashed potatoes, and green beans. Finish with a good sprinkle of chopped parsley for a burst of colour and freshness. This dish is best enjoyed just out of the oven with a glass of red wine and good company.
