Spaghetti alla Carbonara: Rome's World War II Pasta of Eggs, Guanciale, and Pecorino

The name "spaghetti alla carbonara" first appears in print in a 1939 Dutch East Indies newspaper, which mentioned a restaurant in Rome's Trastevere neighborhood known for a dish by that name. But the modern recipe, as the world knows it today, took shape during and immediately after World War II. When Allied forces liberated Rome in June 1944, American soldiers brought with them abundant supplies of bacon and powdered eggs. Italian cooks, particularly in the Trastevere district, combined these with dried pasta and Pecorino Romano to create what became one of the most famous pasta dishes in the world.

The Italian food historian Eleonora Cozzella and others have traced the dish to this period. A young cook named Renato Gualandi is credited by some sources with creating the first version in 1944, using American bacon, powdered egg yolks, cream, and cheese to feed a meeting of American and Italian officers. Whether Gualandi was truly the inventor or the dish emerged more organically from Roman trattorias adapting to available ingredients, carbonara as we know it is a product of wartime necessity transformed by Roman culinary ingenuity.

About the Ingredients: Guanciale is the correct cured pork for carbonara, not bacon or pancetta. Made from pork jowl and cured with salt, pepper, and sometimes garlic, guanciale renders a fat that is richer and more nuanced than bacon. Pecorino Romano, a sharp sheep's milk cheese aged for at least 8 months, provides the salty, tangy backbone. Eggs are used whole and as yolks, creating a silky sauce that coats the pasta. Black pepper should be freshly cracked and generous.

Ingredients (serves 4): - 1 lb spaghetti (or rigatoni) - 6 oz guanciale, diced into ¼-inch pieces - 2 large whole eggs - 4 large egg yolks - 1 cup Pecorino Romano, finely grated, plus extra for serving - Generous amount of freshly cracked black pepper - Salt for pasta water (the water should taste like the sea)

Instructions: Bring a large pot of well-salted water to a boil. The salt is important because the pasta water will season the sauce.

In a large skillet over medium-low heat, cook the guanciale pieces slowly for 8–10 minutes until the fat has rendered and the meat is crisp and golden. The fat should be liquid and golden, not browned. Remove from heat. The guanciale and its rendered fat will stay in the pan.

In a bowl, whisk together the whole eggs, egg yolks, grated Pecorino, and a generous amount of cracked black pepper. The mixture should be thick and paste-like. Set aside.

Cook the spaghetti in the boiling water until al dente, usually 1 minute less than the package instructions. Reserve 1 cup of the pasta water before draining.

Add 2 tablespoons of the hot pasta water to the guanciale pan to stop the fat from solidifying. Add the drained pasta to the pan and toss to coat in the fat.

Remove the pan from the heat. Wait 30 seconds for the pan to cool slightly, then pour in the egg and cheese mixture. Toss vigorously and continuously for 60–90 seconds. The residual heat of the pasta will cook the eggs gently, creating a silky, creamy sauce. If the sauce is too thick, add more pasta water, a tablespoon at a time, until it flows and coats the pasta in a glossy sheen.

Serve immediately in warm bowls with extra Pecorino and more cracked black pepper.

The Mimosa Pairing Logic: The richness of the egg and cheese sauce and the savory depth of the guanciale call for a mimosa with bright acidity to cut through. The Classic Champagne Mimosa is the simplest and most effective pairing, its orange and champagne providing a clean contrast to the pasta's richness. The Black Sesame Honey Prosecco Mimosa offers a more adventurous match, its nutty, honeyed character complementing the Pecorino's tang.

Make-Ahead: Carbonara cannot be made ahead. It must be served the instant it is finished, as the egg sauce tightens and loses its silkiness as it cools. Have your guests seated, bowls warmed, and the table set before you begin. The guanciale can be rendered up to 1 hour ahead and kept at room temperature. The egg and cheese mixture can be prepared up to 1 hour ahead and kept at room temperature.

Pro Tips: The pan must be off the heat when you add the eggs. If the pan is too hot, the eggs will scramble. The residual heat of the pasta is enough to cook the eggs to a food-safe temperature while keeping them silky. If the sauce tightens too much, a splash of pasta water will loosen it immediately. Never add cream. True carbonara has no cream, and its silkiness comes entirely from the emulsion of egg, cheese, pasta water, and rendered guanciale fat.
