T-bone steak is a bone-in steak cut across the short loin, containing striploin on one side of a T-shaped vertebral bone and a smaller portion of tenderloin on the other. It combines two different muscles in one portion, giving the guest contrasting textures and flavours. The size of the tenderloin section depends on where the steak is cut along the short loin.
Both cuts contain striploin and tenderloin separated by a T-shaped bone. In the United States, a porterhouse must have a larger tenderloin section than a T-bone under USDA specifications. Other markets may use the names less precisely, so confirm the supplier’s specification.
T-bone can be grilled, broiled or pan-seared and finished in the oven. The striploin side generally has more fat and can tolerate more direct heat, while the tenderloin side is leaner and cooks more quickly. Use a two-zone grill or adjust the steak’s position to manage the difference. Rest before carving.
Example: grill a thick T-bone, rest it, then carve the striploin and tenderloin from the bone and slice for sharing.
Specify steak thickness, total weight, bone status and tenderloin width when ordering. The bone contributes to raw weight but not edible portion yield, so calculate the cost per usable serving accordingly.
Chef’s tip: use a calibrated thermometer and follow the food-safety process appropriate to the product. Do not rely on colour or the appearance of the bone to determine doneness.
