How to Make Slow-Cooker Lamb Leg
Remove the packaging from the half lamb leg and season with rosemary, thyme, salt, and pepper.
Pour a tiny amount of water into the bottom of your crockpot.
Place the seasoned lamb leg into the crockpot and let slow cook. 3-4 hours on high or 7-8 hours on low. Cooking for longer on a lower heat does produce the best results for soft and tender meat!
After the lamb leg is finished slow cooking, remove from the slow cooker.
Let rest for 10-15 minutes before carving to allow to juices to redistribute throughout the meat.
After the 15-minute rest period is finished, carve your lamb leg and serve!
How to Carve a Lamb Leg on the Bone
- Rest the Lamb – Let the lamb rest for 10-15 minutes after cooking to retain its juices.
- Identify the Bone – Place the lamb on a cutting board and locate the bone running through the centre.
- Make the First Cuts – Start by slicing perpendicular to the bone at the thickest part of the meat. Cut in smooth, even strokes to get slices of uniform thickness.
- Cut Around the Bone – Once you reach the bone, angle your knife to cut the remaining meat away. You may need to rotate the lamb to access all sides.
- Remove Smaller Sections – If large pieces of meat remain attached to the bone, carefully slice them off and cut them into smaller portions.
- Serve Immediately – Arrange the slices on a platter and pour over any resting juices for extra flavour.
A sharp chef’s knife or carving knife works best for smooth cuts, and using a fork or tongs can help hold the meat steady while slicing.

For longer storage, store it in the freezer. Freeze it in portioned containers or freezer bags for up to 3 months.
