Parmigiano-Reggiano, often called the "King of Cheeses," has been produced in the Emilia‑Romagna region since the Middle Ages. It is protected by PDO status, meaning only cheese made in specific provinces using traditional methods can bear the name, and it is a staple on Italian tables, from pasta to salads.

While the PDO standardizes production, subtle differences arise between farms in Parma, Reggio Emilia, Modena, and Bologna. Variations include slight differences in milk composition, aging time, and rind markings, leading to nuanced flavor profiles across the region.

In Italy, Parmigiano-Reggiano is often shaved or grated over risotto, pasta, and soups, served in chunks with balsamic vinegar as an antipasto, or eaten on its own with a drizzle of olive oil. Ultra‑aged wheels are sometimes served as a tasting experience rather than a cooking ingredient.

Parmigiano-Reggiano appears at many Italian celebrations, from family Sunday lunches to festive holidays like Christmas and Easter, where it tops lasagna, gnocchi, and festive salads. In the Emilia‑Romagna region, cheese festivals (Fiera del Parmigiano) celebrate the product.

The authentic sauce uses butter, heavy cream, and a young (24‑month) Parmigiano-Reggiano for smooth melt. Acceptable substitutes include half‑and‑half for cream or a high‑quality aged Pecorino for a sharper flavor, though the texture will differ.

Ultra‑aged Parmigiano-Reggiano shines with simple dishes that let its flavor stand out, such as raw honey drizzled over shards, fresh figs, or a drizzle of aged balsamic. It also pairs with robust red wines and hearty stews where its umami can cut through richness.

The biggest mistakes are overheating the cream, which causes curdling, and adding the 100‑month Parmesan, which won’t melt smoothly. Use the younger 24‑month cheese and keep the sauce at a gentle simmer.

The 24‑month cheese retains more moisture and a milder texture, allowing it to melt into a silky sauce. Older cheeses are drier and form gritty crystals, which would make the sauce grainy.

Yes, slice the cheeses and keep them wrapped in parchment and foil in the refrigerator for up to 3 days. Bring them to room temperature 15 minutes before tasting for optimal aroma.
