Shredded Mozzarella Cheese

Fresh mozzarella and low-moisture mozzarella are genuinely different products — fresh mozzarella's high water content makes it prone to releasing excess liquid when baked, which is why pizza recipes almost universally call for the low-moisture, shredded form instead.

Mozzarella's famous stretchiness comes from its specific protein structure, formed through the pasta filata ("spun paste") cheesemaking process, where curds are heated and stretched repeatedly — a structural trait most other cheeses don't share.

It remains the default pizza cheese even in blends that include other cheeses for flavor, since its stretch and controlled melt are hard to replicate with a firmer or higher-moisture cheese.

In Italy, mozzarella made from water buffalo milk (mozzarella di bufala Campana, itself a protected-origin product from the Campania region) is treated as a genuinely different, more prized product than the cow's-milk mozzarella called fior di latte — both are fresh, high-moisture mozzarella styles, but buffalo milk's higher fat content gives the bufala version a richer, tangier flavor most US shredded mozzarella, made from cow's milk for pizza and baking, doesn't attempt to replicate.

Packaged shredded "mozzarella" blends sold for pizza sometimes include a portion of provolone or another firmer cheese folded in, since mozzarella's flavor on its own is fairly mild and a blend can add more savory depth without sacrificing mozzarella's prized stretch and melt.

Smoked mozzarella (affumicata) is a distinct variant, cold-smoked after the pasta filata stretching process, giving it a golden-tan exterior and a genuine smoky flavor absent from standard fresh or low-moisture mozzarella, used more as a standalone eating cheese or antipasto item than shredded onto a pizza.

Whole-milk mozzarella and part-skim mozzarella are both widely sold pre-shredded, and while the fat difference doesn't change the weight-per-cup figure meaningfully, whole-milk versions do melt with a noticeably richer, glossier stretch than part-skim, a real difference a pizza-maker chasing a specific texture will notice even if a home baker substituting one for the other in a casserole likely won't.

Grating a block of low-moisture mozzarella at home, right before it goes into a dish, is a small step that makes a genuinely noticeable difference in how the cheese melts, since pre-shredded bags are coated with a light dusting of cellulose or potato starch to keep the shreds from clumping together in the package, and that same coating slightly interferes with how smoothly and evenly the cheese melts once it hits a hot pizza or a bubbling pan of baked pasta. Letting shredded mozzarella come closer to room temperature before it goes into the oven, rather than adding it cold straight from the fridge, also helps it melt more evenly rather than seizing on the surface while the underside stays cool.

Beyond pizza and lasagna, shredded mozzarella is the standard filling cheese for mozzarella sticks, breaded and fried or baked until the coating crisps while the center turns molten, a texture contrast that depends entirely on mozzarella's specific stretch and doesn't work nearly as well with a firmer, less elastic cheese substituted in its place.
