Cacio e Pepe
Two ingredients, one technique, endless opportunity to get it wrong. This cacio e pepe recipe uses a Pecorino slurry made off the heat, the trick Roman trattorias rely on to guarantee a creamy sauce instead of a stringy clump.

Method
Tap a step to highlight it, or turn on Cook Mode for large type and step-by-step focus.
-
Cook the pasta in just 1.5 litres of lightly salted water — the smaller volume makes the water far starchier, which is your emulsifier.
-
While it cooks, toast the cracked pepper in a dry pan over medium heat for 45 seconds until it smells sharp and floral. Set aside.
-
Put the Pecorino in a bowl. Add 3 tablespoons of pasta water that has cooled for a minute and stir into a smooth, thick paste, adding more water a teaspoon at a time.
-
Drain the pasta 1 minute early, reserving 250 ml of water, and toss it in the pepper pan off the heat for 30 seconds to cool slightly.
-
Add the Pecorino paste and toss hard, loosening with pasta water until the sauce turns creamy and coats each strand.
-
Serve immediately with an extra grinding of pepper.
Chef’s Tips
- Cracked peppercorns, not pre-ground pepper. The volatile oils that make this dish sing evaporate within days of grinding.
- Let the pasta water cool for 60 seconds before mixing the paste — boiling water will curdle the cheese on contact.
- Some Pecorino is fiercely salty. Taste before salting the pasta water.
Pairing Suggestions
- A cold Frascati Superiore is the Roman default
- Serve with puntarelle or a chicory salad in anchovy dressing
- Finish with a shot of espresso
Storage & Reheating

Is Cacio e Pepe suitable for a special diet?
This recipe is vegetarian and no added sugar. Those labels are checked against the ingredient list, so a dish is only marked when nothing in it contradicts the claim.
Why did my Cacio e Pepe turn oily or grainy instead of creamy?
The cheese seized rather than melted, almost always from too much heat or too little starchy pasta water. Take the pan off the heat before adding the cheese, add it gradually while tossing, and loosen with more of the reserved pasta water rather than trying to fix it with more cheese, which makes a seized sauce worse.
