Ultimate Roast Lamb: 12-hour lamb shoulder

A lamb leg is classic. A 3-hour shoulder is excellent. But for the most succulent roast lamb of your life, slow-roast it for 12 hours in the oven overnight. Cooked at a very low temperature with plenty of braising liquid, you can set-and-forget without a worry. This entirely hands-off, easy cooking method yields superior results with the bonus that it reheats 100% perfectly and you can cook up to 4 shoulders at once.

How to keep it warm during service … If you are planning to serve the lamb buffet-style where people take time to serve themselves, it’s best to serve the lamb inside a slow cooker on warm mode. I place a whole lamb shoulder in there, putting out one at a time (the others stays warm, covered in the oven) and people use tongs to pull the meat off. Easy, no carving, and help-yourself serving!
