Romano Cheese
Romano cheese is a hard, aged Italian-style grating cheese known for its sharp, salty, tangy bite, more assertive than Parmesan and less prone to that sweet, nutty finish. The name covers a spectrum: true Pecorino Romano DOP is made from sheep's milk in Lazio, Sardinia, or parts of Tuscany under strict Italian regulations, while much of what's labeled plain "Romano" in US supermarkets is a cow's milk version made domestically, milder and less complex than the DOP original.
Varieties
There's a real split worth knowing: Pecorino Romano DOP is sheep's milk cheese from a protected Italian region, sharp and distinctly tangy. What's sold simply as "Romano cheese" in most US grocery stores, especially pre-grated versions, is frequently a cow's milk cheese (sometimes called Vacchino Romano) made outside Italy, with a softer, less pungent flavor. Recipes calling for true cacio e pepe or authentic pesto alla genovese specifically mean the sheep's milk DOP version.
Buying tips
For the real thing, look for a wedge stamped "Pecorino Romano" with the DOP seal, cut from a wheel rather than pre-shredded. Generic tubs or shaker-can "Romano" blends are usually cow's milk, often mixed with Parmesan, and taste noticeably flatter. Grate cheese yourself when possible; pre-shredded bags contain anti-caking starches that dull both flavor and melt.
Substitutes
Parmigiano-Reggiano (Parmesan) — 1:1
Milder, nuttier, and less salty than Romano. If a recipe leans on Romano's saltiness, add a small pinch of salt to compensate.
Pecorino Toscano — 1:1
Another sheep's milk cheese but aged less aggressively than Pecorino Romano, so it's softer in both texture and flavor.
Grana Padano — 1:1
Cow's milk and noticeably milder, works well when you want the texture and grating quality of Romano without the sharp bite.
Aged Asiago — 1:1
Sharper and slightly tangier than Parmesan, one of the closer flavor matches to Romano among cow's milk cheeses.
Storage
Wrap a cut wedge first in wax or parchment paper, then loosely in plastic wrap or foil, and refrigerate; a whole piece keeps for several months this way. Pre-grated Romano should go in an airtight container in the fridge and used within one to two weeks, or frozen in a sealed bag for up to three months (it thaws fine for cooking, though texture suffers if eaten plain).
How to use
Grate finely over pasta, risotto, and minestrone, or fold into pesto alongside or in place of Parmesan for a sharper edge. It's the traditional cheese in cacio e pepe and is common in Italian-American meatball and meatloaf mixes, breading for cutlets, and stuffed vegetables where a salty punch is needed in a small amount.
What it pairs with
Works well with cracked black pepper, good olive oil, tomato-based sauces, and fava beans or peas. It also holds up to sweeter counterpoints like honey or ripe pear on a cheese board, which cuts its saltiness.
Nutrition
Romano is high in sodium and saturated fat relative to its serving size, but it's typically used in small sprinkled amounts. It's also a solid source of calcium and protein, and being a long-aged cheese, it carries very little lactose.
FAQ
Is Romano cheese the same as Parmesan?
No. Both are hard grating cheeses, but Parmesan (Parmigiano-Reggiano) is always cow's milk and has a sweeter, nuttier flavor, while true Romano (Pecorino Romano) is sheep's milk and noticeably sharper and saltier.
Is all Romano cheese made from sheep's milk?
No. Only cheese labeled Pecorino Romano is required to be sheep's milk under Italian DOP rules. Generic "Romano cheese" sold in the US, especially in shaker cans or shredded blends, is often made from cow's milk and is much milder.
Does Romano cheese melt well?
Not smoothly. Its low moisture and long aging make it turn stringy or grainy if overheated on its own. It's better grated finely and stirred into a sauce off direct heat, or used as a finishing garnish rather than a melting cheese.
Is Romano cheese lactose-free?
Not entirely, but it's very low in lactose. The long aging process breaks down most of the lactose, which is why many people with mild lactose sensitivity tolerate hard aged cheeses like Romano better than fresh cheeses.
