US National Cheese Pizza Day
<p>The most famous origin story in pizza history is probably a fake. According to the cherished legend, a Neapolitan baker named Raffaele Esposito created the Margherita in 1889 to honour Queen Margherita of Savoy, topping it in tomato red, mozzarella white and basil green to echo the Italian flag. But the historian Zachary Nowak, examining the only physical evidence — a royal thank-you note kept at Pizzeria Brandi — found the seal in the wrong place and a signature that did not match palace records, and concluded the whole tale was “fakelore”. The plain cheese-and-tomato pie at the centre of US National Cheese Pizza Day, observed each 5 September, turns out to have a history far older and more democratic than any queen.</p>

<p>The American observance has no traceable founding decree, which is the usual and honest state of affairs for these single-dish days; it lives in the informal calendar maintained by pizzerias, brands and enthusiasts. Early September is a shrewd choice — the start of the school and university year, the season of late study sessions and casual gatherings, when a shared cheese pie is the default order. The day deliberately honours the plainest version of all: no pepperoni, no extravagant toppings, just dough, sauce and melted cheese.</p>
<h2 id="a-history-with-deep-roots">A history with deep roots</h2>
<p>Flatbreads dressed with cheap, available toppings are ancient, but pizza as a recognisable dish emerged in Naples, where it began as street food for the urban poor. The combination of tomato, mozzarella and basil was already common in the city well before 1889 — it is described in a Neapolitan book of 1866, more than two decades before Esposito supposedly invented it for the queen. The Margherita legend, true or not, did real work: it attached prestige to a peasant food and helped carry its name around the world, even if modern scholarship has unpicked the romance.</p>
<p>The dish crossed the Atlantic with Italian immigrants in the late nineteenth and early twentieth centuries. The first American pizzerias opened in cities such as New York, where the dish took root quickly and then began to mutate. From those beginnings grew a remarkable spread of regional styles: the thin, foldable slices of New York; the tall-walled, knife-and-fork deep-dish of Chicago; the crisp, thin tavern-style of the Midwest; the thick, square Sicilian-style pies of the East Coast. Through every reinvention the plain cheese pizza remained the constant, the baseline against which all others are judged, and that is precisely what 5 September honours.</p>

<p>Cheese pizza earns its day by being genuinely democratic. It is the pie of children’s birthday parties and midnight revision, of family dinners and office Fridays, eaten across every age and income bracket without pretension. The day celebrates that universality while pointing to the dish’s roots and its astonishing adaptability. It also draws quiet attention to the neighbourhood pizzeria — frequently a small, family-run business that anchors its block — and to the broader American love of cheese-led comfort food that runs through observances such as <a href="/specialdate/us-national-mac-cheese-day/">US National <a href="/story/mac-and-cheese/">Mac and Cheese</a> Day</a>. There is a practical wisdom in honouring the plain pie, too: a cheese pizza is the surest test of a kitchen. Strip away the pepperoni and the pile of toppings that can mask a thin sauce or an underproved base, and there is nowhere to hide. Pizza obsessives have long argued that you can judge any pizzeria fairly only by ordering its plainest pie, and the day institutionalises that quiet truth.</p>
<h2 id="the-elements-of-a-great-cheese-pizza">The elements of a great cheese pizza</h2>
<p>For all its apparent simplicity, a good cheese pizza demands that a few fundamentals be right, which is part of what the day invites people to notice. It starts with dough — flour, water, yeast and salt — kneaded and proved so that it develops both flavour and a chewy, open structure. The base is spread with a sauce often kept deliberately plain, letting the sweetness and acidity of good tomatoes do the talking. Then comes the cheese, almost always mozzarella, prized for melting into soft, stretchy strands and browning in appetising patches under fierce heat. The pie is baked as hot as the oven allows, ideally on a stone or steel that crisps the underside while the top blisters. The interplay of well-risen crust, balanced sauce and quality cheese is what separates an ordinary slice from a memorable one.</p>
<h2 id="the-american-regional-styles">The American regional styles</h2>
<p>The single most striking thing about pizza in America is how completely it fragmented into local dialects, and a day for the plain cheese pie is a good moment to map them. New York’s style — wide, thin, foldable slices sold by the slice from corner shops — descends most directly from the Neapolitan immigrant tradition and is the version most of the world pictures as “American pizza”. Chicago answered with deep-dish, baked in a pan with the cheese laid beneath the sauce so it does not burn during the long bake, a construction so substantial it is eaten with cutlery. New Haven, Connecticut, developed its own coal-fired, charred, oblong “apizza”, traditionally ordered plain as a “tomato pie” with cheese as an extra. Detroit built a thick, square, crisp-edged pie in repurposed automotive parts trays, the cheese pushed right to the edges to caramelise against the metal. St Louis cuts a cracker-thin pie into squares and tops it with a processed cheese blend. Each city defends its version with something close to civic pride, and the plain cheese pizza is the common ancestor from which all of them diverged.</p>
<h2 id="how-it-is-celebrated">How it is celebrated</h2>
<p>The day is observed in the most agreeable way imaginable: by eating cheese pizza. Pizzerias across the country run deals and promotions, home cooks stretch their own dough and watch the cheese bubble, and friends argue the eternal questions of crust thickness and the correct ratio of sauce to cheese. Many use the date to taste their way across regional styles, a comparative spirit shared with other cheese-forward food days such as <a href="/specialdate/us-national-cheese-toast-day/">US National Cheese Toast Day</a>, where the simplest treatment of cheese is taken seriously.</p>
<h2 id="variations-around-the-world">Variations around the world</h2>
<p>Pizza has become genuinely global, embraced and rewritten everywhere it lands. Italy guards its Neapolitan tradition fiercely, having secured protected status for true pizza napoletana, while cooks elsewhere top their pies with local ingredients — from Japanese mayonnaise and corn to Brazilian green-pea garnishes and Indian paneer. Despite the endless variation, the cheese pizza remains the common thread, the universal starting point understood from Naples to Tokyo. The image of a single pie sliced and passed round a table has come to stand for ease and company across cultures.</p>
<h2 id="the-cheese-that-makes-the-pizza">The cheese that makes the pizza</h2>
<p>For a day named after cheese pizza, the cheese deserves a closer look, because it is more particular than it seems. Low-moisture mozzarella, not the soft fresh balls of buffalo milk used in Naples, became the American standard precisely because it browns and stretches well under the dry heat of a commercial oven without flooding the pie with water. Its behaviour is a small marvel of food science: the protein casein, loosened by heat, forms the long elastic strands responsible for the famous cheese pull, while the milk fat keeps the surface glossy and the moisture content governs how much it browns. Too wet and the pizza turns soupy; too dry and the cheese scorches into a leathery skin. Pizzerias obsess over this balance, and some of the most distinctive regional styles are defined as much by their cheese choice as their crust — the processed white-cheddar-and-Swiss blend of St Louis, the brick cheese pushed to the caramelised edges of a Detroit pie. The plain cheese pizza, far from being the boring default, is actually the most demanding test of the cheese, because there is nothing else on top to hide behind.</p>
<h2 id="fun-facts">Fun facts</h2>
<ul>
<li>The patriotic Margherita legend is almost certainly invented: the tomato-mozzarella-basil combination was already documented in a Neapolitan book in 1866, decades before the 1889 royal visit it supposedly inspired.</li>
<li>The thank-you note from Queen Margherita’s household, long displayed as proof, was judged a probable forgery by historian Zachary Nowak in 2014, with a misplaced seal and a non-matching signature.</li>
<li>New York-style slices are traditionally folded lengthways so they can be eaten one-handed on the move, while Chicago deep-dish is tall enough to demand a knife and fork.</li>
<li>Pizza began as food for the Neapolitan poor — cheap, fast and eaten in the street — long before it became a global symbol of Italian cuisine.</li>
<li>True Neapolitan pizza is protected by EU designation, with rules covering everything from the flour and the oven temperature to the diameter of the finished pie.</li>
</ul>
<h2 id="a-closing-reflection">A closing reflection</h2>
<p>It is oddly fitting that the world’s most beloved pizza rests on a legend that probably never happened. The Margherita’s invented royal pedigree only dressed up something the people of Naples already knew: that dough, tomato and cheese, handled with care, need nothing more. The plain cheese pizza endures not because a queen blessed it but because it is hard to improve on, and a day given over to the simplest version is really a day for admiring how much can be done with how little.</p>
