Philly cheesesteak Period BOrigin theory BVerified

The Philly cheesesteak is one of Philadelphia's defining quick meals. Thin-sliced beef is griddled with onions and packed into a long Italian roll, with melted cheese running through it: cheap, filling, eaten standing up.

The beginning of the story is clear. Around 1930, the Olivieri brothers, Pat and Harry, ran a hot dog cart in South Philadelphia and began selling thin-sliced beef and onions in a roll. It caught on, and became the starting point of the shop later known as Pat's King of Steaks. In time a second famous shop opened across the street, and South Philadelphia made its name as the home of the cheesesteak.

What made this dish possible was not a new ingredient but the life of the city itself. Beef and cheese were both everyday goods in the Philadelphia of that era, with no need to send away for them. The backdrop was an urban street-food culture sustained by immigrants, Italian-Americans prominent among them. The demand of working people for something cheap and fast to eat out is what rooted this griddled sandwich on the street corners. The first item was a beef sandwich; the cheese that would turn it into a cheesesteak came a little later.

The 'beefsteak sandwich', thin beef in bread, does appear by name in nineteenth-century American cookbooks. But that was a different thing, with a different bread and different seasoning, and not a direct ancestor of the plate we eat now. That an old name existed is one matter; that the dish we know today came into being is another.

That the Olivieri brothers began selling a beef sandwich around 1930 has settled into a well-known and stable account. A 1987 exhibition catalogue from the Library Company of Philadelphia and the Historical Society of Pennsylvania records that this snack developed in the early twentieth century, combining thin-sliced beef, onions, and cheese in a roll, so that not only street lore but the research of local specialist institutions supports this beginning.

The trouble comes at the next step: when, by whom, and with what cheese the sandwich was made into a cheesesteak. Here several claims stand side by side. One holds that in 1951 Joe Lorenza, manager of the Ridge Avenue shop, first added cheese, said to be American, or perhaps provolone. Another has it that in the late 1950s Frank Olivieri brought in Cheez Whiz, the jarred melting cheese. The original steak sandwich of 1930 and the cheese that took hold in the 1950s clearly belong to separate stages, yet the records of that transition are thin. The dates split between the 1940s and 1951 depending on who is telling it, and the type of cheese differs too.

One reason the matter stays open is that many of these anecdotes come from shops claiming to be the origin. A claim that one's own shop was the beginning has to be taken with a grain of salt. Stories are also told of later shops claiming that they were the ones who "perfected" the cheesesteak. But even where such claims are made, they are not about inventing the dish; they are about polishing a house style after the fact, and they do nothing to unsettle the 1930 beginning.

What is certain is the broad outline of the start, a beef sandwich born from a single cart in the South Philadelphia of around 1930, while the slice of cheese that finished it into the famous cheesesteak remains, for now, a matter of storytelling rather than record.
