Lamb leg is a traditional and festive roast that can be prepared in various ways. A true showstopper! Below is a handy guide. Scroll through and choose your preferred preparation method.

Preparing Lamb Leg Low and Slow (searing & roasting)

Plan ahead: Defrost the meat a few days in advance (or in cold water for a few hours) and take it out of the refrigerator 5 hours before cooking to bring it to room temperature.
Preheat: The oven to 120°C for even cooking and the pan or grill to maximum heat.
Sear: Sear the meat on all sides in a large pan with butter or on the grill until it is fully browned, and the fat edge is nicely crunchy.
Transfer: Move the meat to the preheated oven, place the seared lamb leg in an ovenproof dish, and add the cooking juices.
Time: Use the chart below as a guideline; these times are indicative.
Measure: Always check the core temperature for these cuts. Use the temperatures in the chart.
Rest: Let the meat rest for 10 minutes before slicing/serving.
Season: Season the meat after searing or just before serving with salt, pepper, or a rub of your choice.

Core temperature guide:
Rose/Well-done: 62°C (perfect for lamb leg)

Total cooking time: approximately 3 hours.

Reversed Sear Lamb Leg (cooking & finishing on the grill)

Preparing Lamb Leg Sous Vide

Plan ahead: Defrost the meat a few days in advance (or in cold water for a few hours) and take it out of the refrigerator 5 hours before cooking to bring it to room temperature.
Preheat: Heat the water bath to the correct temperature as indicated below. Ensure the vacuum bag is sealed (you can pre-season the lamb and re-vacuum if desired, but typically the packaging can go straight into the water bath).
Time: Set the sous vide stick according to the chart below. If the meat is still frozen, add 1 hour.
Sear: Sear the lamb in a pan or on the BBQ until golden brown. You can also use a torch. The temperature will not rise further during this step.
