What Is Pecorino Romano? Italy's Essential Sheep's Milk Cheese
Share
Pecorino Romano is one of Italy's oldest and most celebrated cheeses. Made exclusively from sheep's milk, it has been produced for more than two thousand years and remains one of the defining ingredients of Roman cuisine.
Its bold, salty flavor and exceptional grating qualities make it indispensable in classic pasta dishes such as Cacio e Pepe, Carbonara, Gricia, and Amatriciana.
What Is Pecorino Romano?
Pecorino Romano is a hard, aged sheep's milk cheese protected by the European Union's DOP (Denominazione di Origine Protetta) designation. This certification guarantees that the cheese is produced according to strict traditional methods within designated regions of Italy.
Unlike cow's milk cheeses such as Parmigiano Reggiano or Grana Padano, Pecorino Romano develops a sharper, saltier flavor that stands up beautifully to simple pasta dishes.
What Does DOP Mean?
DOP, or Protected Designation of Origin, ensures that every stage of production—from the milk to the aging process—takes place according to centuries-old traditions in approved Italian regions.
When you purchase authentic Pecorino Romano DOP, you are enjoying a cheese whose quality and authenticity are protected by Italian and European law.
Pecorino Romano vs. Parmigiano Reggiano
| Pecorino Romano | Parmigiano Reggiano | |
|---|---|---|

| Best Uses | Roman pasta dishes | Risotto, soups, table cheese |
| Traditional Carbonara | ★★★★★ | ☆☆☆☆☆ |
Why Romans Choose Pecorino Romano
The higher salt content and distinctive sheep's milk flavor of Pecorino Romano create the bold taste that defines Roman cuisine. Its texture also allows it to emulsify beautifully with pasta water, creating creamy sauces without cream or butter.
For this reason, Roman cooks traditionally use Pecorino Romano—not Parmesan—in Carbonara, Cacio e Pepe, Gricia, and Amatriciana.

Can You Substitute Parmesan?
Many recipes outside Italy suggest substituting Parmigiano Reggiano for Pecorino Romano. While this certainly produces a delicious pasta dish, the result is no longer traditional Roman cooking.
Parmigiano Reggiano is milder, sweeter, and less salty. Pecorino Romano delivers the bold flavor and creamy texture that make these iconic Roman recipes unique.
How to Store Pecorino Romano
Wrap Pecorino Romano loosely in cheese paper or parchment followed by plastic wrap and keep it refrigerated. Properly stored, it will maintain its quality for several weeks after opening.
For the best flavor, remove the cheese from the refrigerator about 30 minutes before serving.
