A lamb roast is often served for holiday or special occasion dinners. A slow cooker promises moist, tender lamb roast every time. A simple lamb roast takes very little preparation time and the slow cooker or crock pot will cook the roast to perfection with no fuss. Using a slow cooker to roast the lamb means you have the time to prepare other dishes on your menu.


Step 1

Use the sharp knife to remove the fell from the lamb roast. The fell is the paper thin, pinkish-red layer on the outside of the meat.

Step 2

Heat a heavy skillet with four tablespoons of oil to very hot over medium high heat.


Step 3

Brown the roast by searing the outside in the hot oil. Use tongs or a meat fork to turn the roast so that all sides can be browned and seared.

Step 4

Place the seared roast in the slow cooker.


Step 5

Sprinkle chopped rosemary over the entire roast, turning with the tongs or fork to cover the entire roast.

Step 6

Place the lid on the slow cooker and turn the heat on low.

Step 7

Allow the lamb to cook for six to eight hours in the slow cooker.


Step 8

Check the internal temperature of the roast with a meat thermometer. The meat is done when the temperature reads 150 degrees.

Step 9

Remove the roast from the slow cooker and let it rest on a platter for 15 to 20 minutes before slicing.


If you have a recipe for stuffed lamb roast, pound the roast to an even thickness, place the stuffing in a layer on top and roll the roast into a cylinder. Tie the cylinder with string to help the roast keep its shape while cooking.

If your slow cooker has a warm setting, once the roast has reached 150 degrees internally, you can use the warm setting to hold the roast until you are ready to eat.
