Cacio e pepe

What is Cacio e pepe?

Cacio e pepe is a simple pasta dish that brings together just a few ingredients: pasta (often tonnarelli or spaghetti), grated pecorino romano cheese, and black pepper. The name means 'cheese and pepper' in Italian dialects. When prepared well, the cheese melts into a smooth, creamy sauce that coats each strand of pasta, with flecks of black pepper throughout. The taste is sharp and salty from the sheep’s milk cheese, balanced by the warmth of the pepper.

Where does Cacio e pepe come from?

This dish comes from the Lazio region, with strong roots in Roman cooking. The name cacio e pepe reflects its main ingredients in local dialect. Stories link its invention to shepherds in central Italy—Lazio, Abruzzo, Tuscany, and Umbria—who needed simple, durable foods. While cheese and pasta were staples, black pepper was likely added later, as it was once costly and rare. The dish has been part of Roman tradition since at least the 18th or 19th century.

How is Cacio e pepe made?

To make cacio e pepe, pasta is boiled in salted water. Once cooked, it is mixed with grated pecorino romano and freshly ground black pepper. A bit of the hot, starchy pasta water is added to help the cheese melt and form a creamy sauce that clings to the pasta. Achieving a smooth texture is tricky, as the cheese can clump if the temperature or water amount is not right. Chefs and researchers have studied the process to perfect the creamy result.

How and when is Cacio e pepe eaten?

Cacio e pepe is usually served as a first course (primo) at lunch or dinner in Italy, especially in Rome and the Lazio region. It is enjoyed hot, straight after mixing, and is rarely paired with other sauces or toppings. The dish is valued for its simplicity and is a common choice both at home and in trattorias. It is not tied to any particular festival or religious occasion, but is a staple of everyday Roman meals.

Kinds of Cacio e pepe

The classic version uses tonnarelli, a thick, square-cut pasta, but spaghetti is also common. Some cooks experiment with other pasta shapes or add extra ingredients, but purists stick to the original three. Modern chefs sometimes use different techniques to keep the sauce creamy, such as adjusting the temperature or starch content, but the core ingredients remain unchanged.
