A guide to Pecorino Romano — the hard, salty Italian sheep's-milk cheese. How it differs from Parmesan and the pasta dishes that depend on it.
Pecorino Romano is one of Italy's oldest and most important cheeses — a hard, intensely salty, savory sheep's-milk cheese that's the backbone of some of Rome's most famous pasta dishes. Sharper and saltier than Parmesan, it brings a bold, tangy punch that's essential to authentic Roman cooking.
What Pecorino Romano Is
Pecorino Romano is a Protected Designation of Origin (DOP) hard cheese made from sheep's milk — pecora means "sheep" in Italian. Despite the "Romano" name, most of it is now produced on the island of Sardinia, along with the Lazio region around Rome and parts of Tuscany. It's an ancient cheese that was a staple ration for Roman legionaries, prized for its keeping qualities and concentrated nourishment.
Flavor and Texture
Pecorino Romano is hard, dry, and granular, pale ivory in color, breaking into sharp shards. Its defining qualities are saltiness and tang: it's markedly saltier than Parmigiano-Reggiano, with a sharp, piquant, savory flavor and a distinctive sheep's-milk richness. This boldness is exactly why it's used as a seasoning cheese, where a little adds a big savory, salty hit.
Pecorino Romano vs. Parmesan
The two hard grating cheeses are often compared and sometimes substituted, but they're quite different. Parmigiano-Reggiano is made from cow's milk and is nutty, sweet, and savory; Pecorino Romano is made from sheep's milk and is saltier, sharper, and tangier. In many Roman recipes, the saltiness and bite of Pecorino are essential and can't be fully replicated by Parmesan, though some cooks blend the two.
The Roman Pasta Classics
Pecorino Romano is indispensable in Rome's "holy trinity" of pasta dishes. In cacio e pepe ("cheese and pepper"), it's melted with pasta water and black pepper into a creamy sauce. In pasta alla gricia and amatriciana, it adds salty depth alongside cured pork (guanciale). And in true carbonara, Pecorino Romano (sometimes with a little Parmesan) is the cheese that, with egg, creates the silky sauce. Mastering these dishes means working with Pecorino.
How to Use Pecorino Romano
Grate it generously over pasta, especially robust, peppery, or tomato-based sauces, where its saltiness shines. Use it to season vegetables, soups, and salads, or shave it onto antipasti. Because it's so salty, you'll often need less added salt in a dish that includes it. A little also makes a sharp, savory addition to a cheese board.
Buying and Storing
Look for "Pecorino Romano DOP" stamped on the rind. Note that "pecorino" alone simply means sheep's cheese, and other pecorinos (like the milder Pecorino Toscano) are quite different. Wrap it in parchment and foil and keep it in the fridge, where this hard, dry cheese keeps for a long time.

Why is Pecorino Romano so salty?
Heavy salting is part of its traditional production and preservation, which is why it's used as a bold seasoning cheese.
What pasta dishes use Pecorino Romano?
The Roman classics: cacio e pepe, carbonara, amatriciana, and pasta alla gricia all rely on it.
