National Pepperoni Pizza Day Is Here, But Why Did Pepperoni Become America’s Favorite Topping?

There are plenty of ways to build a pizza, yet Americans keep coming back to the same combination of tomato sauce, melted cheese, and those little spicy red coins.

September 20 is National Pepperoni Pizza Day, an unofficial food celebration dedicated to one of America’s most recognizable pizza toppings. The date comes around every year, though the holiday’s origins remain surprisingly mysterious. Even after years of being celebrated, nobody has clearly stepped forward as the person who decided pepperoni deserved its own day.

That mystery almost feels appropriate. Pepperoni has an equally complicated history, because despite its unmistakably Italian-sounding name, the sausage Americans know as pepperoni is actually an Italian-American creation.

Pepperoni Isn’t Really Italian

The name sounds like it belongs in an Italian butcher shop, but the story is much more American than you might expect.

Traditional Italian cuisine has no direct equivalent of American pepperoni sausage. Instead, the meat developed in the United States through Italian-American food traditions, with immigrant butchers adapting cured-sausage techniques to American tastes. Pizza Today’s history of pepperoni describes it as a New World creation, despite the Italian roots of the communities that helped develop it.

Even the word creates confusion. In Italian, peperoni refers to peppers, not the spicy cured meat Americans scatter across pizza. Somewhere along the way, an Italian-derived word became attached to a distinctly American sausage.

That little linguistic twist is part of what makes pepperoni so interesting. It is a food shaped by immigration, adaptation, American tastes, and eventually the enormous popularity of pizza.

Why Americans Keep Choosing It

Pepperoni hits several cravings at once: salty, spicy, fatty, savory, and wonderfully crisp around the edges.

A 2023 YouGov survey of 1,000 U.S. adults found that 24% named pepperoni as their favorite pizza topping, putting it ahead of sausage at 13%, extra cheese at 11%, mushrooms at 9%, and chicken at 6%. Even more revealing, fewer than 1% selected pepperoni as their least favorite topping. YouGov’s survey of Americans’ favorite pizza toppings shows just how unusual that combination of popularity and low rejection is.

The appeal is partly about what happens in the oven. Pepperoni releases fat as it cooks, allowing its edges to brown while the center stays flavorful and juicy. Depending on the style, slices can remain flat or curl into little cups that collect rendered fat and develop crisp, deeply browned edges.

Tomato sauce brings acidity, mozzarella adds creaminess, and pepperoni supplies salt, spice, and richness. When all three are balanced properly, the topping does not simply sit on the pizza—it changes the entire bite.

The Holiday Has a Mystery Too

For all the attention surrounding September 20, nobody seems to know exactly who created National Pepperoni Pizza Day.

The observance is not a federal holiday or an official government celebration. It belongs to the world of food-calendar traditions, where particular foods get their own day, and restaurants can turn the occasion into promotions, specials, and an excuse for customers to order another pizza.

Pizza businesses have certainly embraced it. A recent Pizza Today celebration of National Pepperoni Pizza Day points out that the topping remains No. 1 in the United States and highlights how many styles now exist, from traditional flat slices to thick, chewy pieces and cup-and-char varieties.

The lack of a known founder has not stopped the tradition from becoming part of the food calendar. At this point, most people probably care more about eating the pizza than discovering who first put September 20 on the calendar.

There Is More Than One Kind of Pepperoni

The pepperoni on your pizza can completely change the experience depending on how it is sliced and baked.

Thin slices tend to crisp quickly and release plenty of fat, while thicker cuts stay meatier and chewier. Some pizza makers place pepperoni beneath the cheese, while others leave it exposed so the edges can blister and brown directly against the heat.

Then there is cup-and-char pepperoni, which curls during baking and forms little bowls around the edges. Those cups trap rendered fat, creating an especially rich bite with crisp edges and a softer center.

The style has become popular enough that pizza makers now deliberately choose pepperoni based on the texture they want. It reminds us that even familiar foods can become more interesting when small details change.

Pepperoni Became Part of the American Pizza Ritual

Eventually, pepperoni stopped being just another topping and became shorthand for pizza itself.

It works at children’s birthday parties, Friday-night dinners, game nights, office lunches, road trips, and those evenings when nobody wants to cook. Its familiarity is part of its power: order a pepperoni pizza almost anywhere in America, and you already have a good idea of what is coming.

That kind of dependable food fits naturally into simple everyday food routines, especially when the goal is something satisfying without spending half an hour deciding what everyone wants.

And perhaps that is why pepperoni has lasted. It does not require an adventurous palate or a complicated explanation. It is salty, savory, crispy around the edges, wonderfully greasy, and immediately recognizable.

The Perfect Pepperoni Pizza Is Still Debatable

National Pepperoni Pizza Day may celebrate the topping, but the real argument is about how it should be served.

Should pepperoni be paper-thin or thick and chewy? Should it curl into crisp cups or remain flat? Should it sit underneath the cheese or be proudly exposed across the top?

There is no universal answer, and that is the fun of it. The best pepperoni pizza is often the one that matches the kind of night you are having rather than some official definition of perfection.

Pepperoni’s journey from an Italian-American invention to America’s favorite pizza topping says something interesting about food itself. Sometimes the foods that become cultural icons are not the oldest or most traditional, they are the ones people keep adapting until they become their own tradition.

On National Pepperoni Pizza Day, do you want your pepperoni crispy and curled, or soft, flat, and loaded with that classic savory flavor?
