What is Cacio e Pepe?

Cacio e pepe (cheese and pepper) is a Roman pasta dish that uses no butter, no oil beyond the pasta water, and no garlic. The sauce is made by emulsifying finely grated Pecorino Romano (and sometimes Parmigiano-Reggiano) with starchy pasta cooking water and freshly ground black pepper. The result should be creamy and clinging, not grainy.

Taste and texture

Sharp and salty from the Pecorino, with the heat and floral bite of black pepper. The texture is silky and coating. It's richer than it appears because the cheese and starch create a natural sauce without added fat.

Typical ingredients

• Spaghetti, tonnarelli, or rigatoni
• Pecorino Romano (finely grated)
• Black pepper (coarsely ground, freshly)
• Pasta cooking water (starchy)

Common allergens to ask about

The following allergens are commonly present in Cacio e Pepe. Ingredient lists vary by restaurant — always confirm with your server if you have dietary restrictions.

• Wheat (pasta)
• Dairy (Pecorino Romano)
• Egg (some pasta types)

How it's served

In a bowl or plate. No garnish needed beyond extra pepper. The pasta should be served immediately as the sauce continues to set after plating.

Order it if you like…

Order it if you want something deeply satisfying with a pure flavour — this is not a mild pasta. The sharpness of Pecorino and the intensity of black pepper make it stand out against cream-based or tomato-based pastas.

Frequently asked questions

Is cacio e pepe the same as mac and cheese?

No. Cacio e pepe uses no butter, no flour, and no American cheese. The emulsification is achieved entirely through starchy pasta water and finely grated hard aged cheese. The flavour is sharper and more complex.

What is Pecorino Romano?

Pecorino Romano is a hard, sharp, salty sheep's milk cheese from Lazio and Sardinia. It's saltier and more pungent than Parmigiano-Reggiano (which is cow's milk). Some recipes use a blend of both.

Why does cacio e pepe sometimes turn grainy?

The cheese can clump if the pasta is too hot or the technique is off. Proper emulsification requires removing the pan from direct heat and adding the cheese gradually with enough pasta water. Restaurants with experience rarely have this issue.
