Pecorino or parmesan on pizza – what’s the difference
Pecorino romano is salty and sharp; parmigiano reggiano milder and nuttier. What AVPN actually says about it, and which topping suits which cheese.
Quick answer: Pecorino romano is a salty, sharp sheep’s-milk cheese from Lazio/Sardinia; parmigiano reggiano is a milder, nuttier cow’s-milk cheese aged for considerably longer. Some versions of AVPN’s recipe mention a light dusting of grated pecorino as optional before the mozzarella goes on — but it’s not a fixed requirement, and ordinary parmesan works just as well if you prefer a milder flavour.
Two completely different cheeses, even though both are ”just grated cheese”
Pecorino romano DOP is made from sheep’s milk and aged for less time than parmesan, which gives it a considerably saltier, sharper and bolder flavour. Parmigiano reggiano DOP is a cow’s-milk cheese aged for at least 12 months, often 24–36, which builds up a nutty, almost caramelised sweetness with a lower salt content than pecorino. Swap one straight for the other in a recipe and you’ll notice the difference immediately — pecorino takes over the flavour profile in a way parmesan doesn’t.
Where the cheese actually appears in the rules
AVPN’s core Margherita recipe is built on tomato, mozzarella, basil and olive oil — no grated cheese as standard. Several published versions of the recipe, including ones circulating from training materials and pizzerias’ own interpretations, do include a light dusting of grated pecorino romano straight onto the tomato sauce, before the mozzarella goes on. AVPN’s disciplinare lists grated hard cheese as an optional addition on the Margherita, 5–7 g, sprinkled on the sauce before the mozzarella — a genuine variant, not a requirement.
Which cheese suits which topping
Pecorino’s saltiness and sharpness make it a natural partner for already salty, intense ingredients: anchovy (see alici e capperi), strong salumi (see diavola) or onion and salty flavours (see cipolla e acciughe). Parmesan fits better into milder or already cheese-rich combinations where you want depth without the cheese taking over, as in quattro formaggi or alongside mushrooms.
How much, and when
A light dusting is enough — grated pecorino or parmesan should add background depth, not cover the pizza. Put it straight on the tomato sauce before the mozzarella, in line with the order in topping order, so it bakes into the cheese rather than sitting exposed and burning.
Frequently asked questions
Can I mix both? Yes, a small mix gives both saltiness and nuttiness without either one fully dominating.
Does an aged Swedish hard cheese work instead? An aged hard cheese gives a different but perfectly usable result — more nutty sweetness, less of pecorino’s distinct sheep’s-milk flavour.
