About Roast beef

Roast beef is a large, lean cut from the rump or sirloin, meant to be cooked whole and then sliced thin. It is eaten both hot and cold, and the cold version adds its own requirement.

On a large piece the temperature gap between edge and core is far wider than on a steak. Roast it hot and the outer centimetre is already grey before the middle has come up. The answer is to cook it low, around 120 degrees oven temperature, and only sear it briefly and hot at the end for the crust.

Carryover is substantial here: expect three to five degrees after it leaves the oven, so pull it well below your target. Roast beef intended to be served cold is also better taken slightly less far, because the meat looks firmer and darker once chilled.

Rest it for at least fifteen minutes before slicing, and slice it paper thin across the grain. On a lean cut like this, slice thickness does nearly as much for tenderness as the cooking temperature.
