Parmesan Cheese
Parmesan cheese (known in Italy as Parmigiano-Reggiano) is a hard, granular, aged cow’s milk cheese famous for its nutty, savory umami flavor, crystalline texture, and versatility in cooking. It’s often called the “King of Cheeses” for its rich history and strict production standards.
Authentic Parmigiano-Reggiano vs. Generic Parmesan
True Parmigiano-Reggiano is a Protected Designation of Origin (PDO) cheese. It can only be produced in specific regions of northern Italy (primarily Parma, Reggio Emilia, Modena, parts of Bologna, and Mantua) using traditional methods. The name “Parmesan” is simply the English/French translation, and in the EU, only the authentic Italian version can legally be called Parmesan.
In the United States and many other countries, “Parmesan” is not strictly regulated, so products labeled as such are often imitations made elsewhere (e.g., in Wisconsin or Argentina). These can still taste good but are usually milder, aged less, and may include additives. Look for the words “Parmigiano-Reggiano” on the label, along with the dotted rind embossed with “Parmigiano-Reggiano” and the consortium’s certification marks for the real thing.
How It’s Made
Authentic Parmigiano-Reggiano uses just three ingredients: raw (unpasteurized) cow’s milk, salt, and rennet (an enzyme from calf stomachs, which makes it non-vegetarian). Morning whole milk is mixed with the naturally skimmed milk from the previous evening.
It’s heated in massive copper vats with a whey starter culture and rennet to form curds.
The curds are broken into tiny rice-sized granules, cooked to about 55°C (131°F), then lifted out in linen cloths to form massive wheels (each requiring roughly 550 liters/145 gallons of milk and weighing about 40 kg/88 lbs).
Wheels are brined for weeks, then aged on wooden shelves in temperature-controlled rooms for a minimum of 12 months (often 18–36+ months for “Vecchio” or “Stravecchio” versions). They are regularly brushed and turned.
The result is a dense, dry cheese with crunchy tyrosine crystals and a complex, fruity-nutty depth that intensifies with age.
Flavor, Texture, and Nutrition
Flavor: Deeply savory (umami), nutty, slightly sweet and fruity, with a salty edge. Longer-aged versions develop sharper, more caramel-like notes.
Texture: Hard and crumbly when young; granular and crystalline when aged. It grates beautifully but can also be eaten in chunks.
Nutrition (per 1 oz/28g serving of Parmigiano-Reggiano): 110–120 calories, 10g protein, 8g fat (mostly saturated), minimal carbs/lactose (it’s naturally lactose-free due to long aging), high in calcium (27–30% DV), phosphorus, and other minerals. It’s nutrient-dense but high in sodium.
How to Use ItParmesan shines as a finishing cheese:Grated over pasta, risotto, soups, salads, or roasted vegetables.
In classics like Caesar salad, chicken Parmesan, or Alfredo sauce.
Shaved onto charcuterie boards or drizzled with balsamic.
The rind is edible and adds incredible flavor—toss it into soups, broths, or sauces while simmering (remove before serving). Don’t throw it away!
Buying and Storage TipsBuy in blocks or wedges and grate fresh for best flavor (pre-grated loses aroma quickly and often contains anti-caking agents).
Store wrapped in parchment or wax paper in the fridge’s cheese drawer; it lasts months.
For the best experience, seek out aged wheels (24–36 months) from reputable sources—it’s worth the premium price for the superior taste and authenticity.
