Pecorino Romano vs Parmigiano: Which to Use and When
Pecorino Romano and Parmigiano Reggiano are both Italian hard grating cheeses, and in many kitchens they are used interchangeably. But they are quite different: one is made from sheep’s milk, the other from cow’s; one is sharp and salty, the other nutty and sweet. Knowing when to use which will make your pasta, risotto and boards noticeably better.
The essential difference
Pecorino Romano is made from sheep’s milk and is saltier, sharper and tangier. Parmigiano Reggiano is made from cow’s milk and is nuttier, sweeter and more complex. Pecorino is the bold seasoning; Parmigiano is the refined finisher.
Pecorino Romano
Pecorino Romano is a hard, salty sheep’s milk cheese from Lazio and Sardinia, aged for at least five months — much shorter than Parmigiano. It was historically the cheese of Roman soldiers, prized for its salt. Its sheep’s-milk tang and pronounced salt make it a powerful grating cheese.
Parmigiano Reggiano
Parmigiano Reggiano is aged 12 to 36 months or more, developing a dense, granular texture and a long, savoury, umami-rich flavour with notes of pineapple and broth. It is mild enough to eat in shards yet complex enough to be the star of a board.
When to use each
- Pecorino: Roman pasta — cacio e pepe, carbonara, amatriciana, and pesto. Its salt and tang define those dishes.
- Parmigiano: risotto, bolognese, béchamel, shaved over pasta, and eaten on its own.
- Both together: many Italian recipes blend them, using Parmigiano for depth and Pecorino for bite.
The classic blends
Some of the best-known dishes deliberately combine the two. Traditional carbonara, for instance, is often made with a mix of Parmigiano and Pecorino — the first for richness, the second for salt and tang. Try it and taste the balance.
Pairings
- Pecorino: a full-bodied red, or a Pecorino wine from the same region; also pairs with honey and pears
- Parmigiano: Barolo, Lambrusco, balsamic, walnuts
Frequently asked questions
Can I substitute one for the other?
In small amounts, yes — but reduce Pecorino (it is much saltier) or increase Parmigiano. In a Roman pasta dish, substituting changes the dish significantly.
Are they both vegetarian?
Both traditionally use animal rennet. Some brands offer vegetarian versions — check labels.
Which grates more easily?
Both are hard and grate well. Pecorino is a little drier and crumbles more; Parmigiano grates finely but is prone to crumbling when very old.
