The origin of sirloin is a subject that has intrigued food historians for generations, and the answer is as layered as the cut itself. To trace its roots, one must travel back to the medieval kitchens of France, where the term sur l'oignon—literally “over the onion”—was used to describe the portion of beef that sat atop the animal’s loin. The “onion” in this context referred not to the vegetable but to the small, bony protrusion known as the os coxae, or hip bone, which resembles a small knob. French butchers prized this region for its marbling and tenderness, and the phrase sur l'oignon entered the culinary lexicon as a precise anatomical reference.
When the Normans conquered England in 1066, they brought their culinary vocabulary with them. The French sur l'oignon was Anglicized first as “sirloin” in Middle English documents from the 14th century, a phonetic simplification that retained the original meaning of “over the loin.” The transition from a technical descriptor to a common noun reflects how the cut gradually moved from the exclusive domain of royal kitchens to the broader market.
Royal folklore adds another intriguing dimension to the story. While the exact anecdote varies, one persistent legend holds that King Henry VIII, known for his lavish banquets, declared the “sirloin” the “king of steaks.” According to the tale, the king’s chefs would present the cut on a silver platter, and the monarch would bestow a ceremonial “knighthood” upon the butcher who first perfected the preparation.
