Sirloin on the Bone – The Ultimate Beef Roasting Centrepiece Sirloin on the Bone is a true showstopper – a richly marbled, full-flavoured roasting joint that’s perfect for special occasions or a luxurious family meal. Cut from the middle back of the carcase, this classic joint includes the sirloin with its natural fat covering and the rib bone attached, which adds flavour and helps keep the meat moist during roasting. At Northfield Farm, we carefully select and dry-age our grass-fed sirloins on the bone to bring out their deep, savoury character and tenderness. We dry-age our grass-fed sirloins on the bone for 3–5 weeks in our ageing chambers to deepen the flavour and enhance tenderness. The result is an exceptional joint that delivers old-fashioned beefiness with every bite. Our expert butchers can prepare bespoke joint sizes to suit your table – whether you're after a small bone-in sirloin for a romantic meal, or a large roasting joint to feed a crowd.
