what temperature do you slow cook roast lamb
Slow roasting would have to be one of the easiest ways to cook lamb, in fact itâs a roast that practically cooks itself! Cuts. Best lamb cuts are lamb leg and shoulders, as well as lamb shanks. Timing-two options. Cook in the oven: at 140ÂºC for around 4 hours; or a little faster at 160ÂºC for 2-3 hours.Season the lamb well a generous dusting of herbs like fresh rosemary or dried oregano or any other herb of your choice.You can also rest it on some garlic cloves or onion wedges if you like. Make sure the lamb roast stands at room temperature for around 15 -20 minutes before cooking. 2  This takes the fridge chill from the lamb and allows it to cook evenly.
