Spaghetti alla carbonara is a quintessential Roman pasta dish, deeply rooted in the culinary traditions of the Lazio region. Its rich and savory flavor profile, achieved with a few simple ingredients, has made it a beloved dish worldwide. While its exact origins are debated, the carbonara has become synonymous with Roman cuisine.
Origins and History
The roots of spaghetti alla carbonara can be traced back to the Lazio region, specifically to a pasta dish called "cacio e ova" (cheese and egg). This dish was a staple for shepherds and charcoal makers ("carbonari" in Roman dialect) who spent long periods in the mountains. They would carry dried pasta, cheese, and eggs, which were easily transportable and provided sustenance during their work.
The American Influence
The modern carbonara, as we know it today, is believed to have evolved during or shortly after World War II. One popular theory suggests that American soldiers stationed in Italy during the war played a role in its creation. The soldiers, accustomed to bacon and eggs for breakfast, may have requested Italian chefs to incorporate these ingredients into a pasta dish. This led to the addition of bacon to the "cacio e ova," eventually evolving into the carbonara.
From Bacon to Guanciale
Over time, the bacon was replaced with guanciale, a cured pork cheek that is more traditional to the Lazio region. Guanciale adds a richer, more complex flavor to the dish. Other additions, such as cream and onions, which were sometimes used to enhance the sauce, were eventually discarded in favor of a simpler, more authentic recipe.
Early Mentions in Cookbooks
Interestingly, the first published recipe for carbonara did not appear in Italy but in Chicago in 1952, within a guide to restaurants. The author of the guide, Patricia Bronté, included a precise recipe for the dish served at Armando's restaurant, leaving no doubt that it was indeed the carbonara we know today.

In Italy, a recipe that deviated from the modern version appeared in the magazine "La Cucina Italiana" in August 1954, featuring garlic and Gruyère cheese. The following year, a more familiar version appeared in Felix Dessì's "La signora in cucina." The dish gained national recognition in 1960 with its inclusion in Luigi Carnacina's cookbook, "La grande cucina."
The Abruzzo Connection
Another theory links the origin of carbonara to the Appennine region of Abruzzo. According to this theory, the dish was created by charcoal makers from Abruzzo who brought long-lasting ingredients with them, such as eggs and smoked guanciale. Recipes for "cacio e ova" are widespread in Abruzzo.
It is said that Allied soldiers tasted the typical Abruzzese pasta "cacio e ova" and fell in love with it between 1943 and 1944 when they were stationed for more than eight months on the Gustav Line, which bisected Abruzzo. The Abruzzese tradition would then have been adapted to the tastes of the soldiers and their supplies, using U.S. smoked bacon. Eggs and bacon, flavors that reminded the soldiers of "home," were the ingredients that characterized the typical American breakfast.
Neapolitan Influences
A more recent theory suggests a connection between carbonara and Neapolitan cuisine. This theory points to the Neapolitan tradition of adding beaten eggs with cheese and pepper at the end of cooking, a technique found in several recipes. This technique is mentioned in Ippolito Cavalcanti's early 19th-century cookbook and is traditionally associated with dishes such as pasta with peas or zucchini. However, this theory does not explain the name or the Roman origin of the recipe.
The Authentic Recipe
The classic spaghetti alla carbonara recipe comprises only five key ingredients:

- Pasta: Traditionally spaghetti, but rigatoni or other pasta shapes can also be used.
- Guanciale: Cured pork cheek, the most authentic choice for a rich, savory flavor.
- Pecorino Romano: A salty, hard cheese made from sheep's milk, essential for the dish's distinctive taste.
- Eggs: Fresh eggs, typically a combination of whole eggs and yolks, create the creamy sauce.
- Black Pepper: Freshly ground black pepper adds a spicy kick and enhances the other flavors.
Variations and Interpretations
While the traditional recipe is cherished, numerous variations exist, reflecting regional preferences and culinary creativity. Some common variations include:
- Pancetta: While guanciale is preferred, pancetta (cured pork belly) is sometimes used as a substitute.
- Parmesan Cheese: In some variations, Parmesan cheese is added to or used in place of Pecorino Romano.
- Cream: Although frowned upon by purists, cream is sometimes added to create a richer, smoother sauce.
- Garlic and Onion: Some recipes include garlic or onion for added flavor, though these are not traditional ingredients.
- Other additions: Some chefs add white wine, parsley, chili pepper and other ingredients to the recipe.
Regional Variations
The Carbonara recipe has been interpreted in many ways. This has led to the creation of regional variations that incorporate local ingredients and flavors.
- Carbonara allo Zafferano: This variation adds saffron to the classic recipe, giving it a golden color and a unique flavor.
- Carbonara di Zucchine: A lighter version of the dish, using zucchini instead of guanciale.
- Vegetarian Carbonara: In this variation, guanciale is replaced with smoked tofu, and a mixture of soy milk, turmeric, and black pepper is used instead of eggs.
Tips for Making Perfect Carbonara
- Use high-quality ingredients: The quality of the ingredients is crucial for the success of the dish. Choose good-quality pasta, fresh eggs, and authentic guanciale and Pecorino Romano.
- Cook the guanciale properly: Cook the guanciale over low heat to render the fat and crisp it without burning.
- Don't overcook the eggs: The key to a creamy carbonara sauce is to cook the eggs gently using the heat of the pasta and the rendered guanciale fat. Avoid scrambling the eggs by adding them off the heat and stirring quickly.
- Use pasta water: Adding a little pasta water to the sauce helps to create a smooth, emulsified sauce that coats the pasta evenly.
- Serve immediately: Carbonara is best served immediately after preparation to prevent the sauce from becoming too thick or dry.
