Three-ingredient Roman pasta of pecorino, pepper and starchy water.
Rome, Lazio, Italy
About Cacio e Pepe
Tonnarelli pasta is tossed with pecorino romano, cracked black pepper and a splash of starchy cooking water until the cheese emulsifies into a glossy, clinging sauce. Its genius lies in how few ingredients deliver so much flavour.
History & Culture
Cacio e pepe is a cornerstone of Roman cuisine, hailing from the Lazio region. Its origins are debated, though a common account ties it to shepherds who carried aged pecorino romano, black pepper, and dried pasta as durable provisions for the countryside. In Rome, it is classically made with tonnarelli or spaghetti, but the fundamental ingredients - pasta, pecorino, pepper, and starchy water - remain constant across variations.
The dish exemplifies the Italian "cucina povera" tradition, where a few humble ingredients are transformed through technique into a rich, glossy sauce. Its cultural significance lies in its deceptive simplicity: achieving the perfect emulsion without cream or butter requires skill and practice, making it a benchmark of true Roman cooking. It remains a beloved staple in trattorias and home kitchens alike, celebrated worldwide as a pure expression of Italian flavor.

Recipe ingredients
- 400 g (14 oz) tonnarelli pasta, fresh if available; spaghetti or bucatini are common home substitutes
- 200 g (7 oz) pecorino romano, finely grated, pasta的制作 pecorino only; do not substitute with parmesan if authenticity is desired
- 15 g (1 tbsp) whole black peppercorns, toasted and freshly cracked
- 15 g (1 tbsp) fine sea salt, for the pasta water only; the pecorino is already salty
- 1200 ml (5 cups) water, plus extra as needed for the sauce
Steps
- 1 Bring 1200 ml (5 cups) of water to a boil in a wide pot, add the 15 g (1 tbsp) of fine sea salt, and drop in the 400 g (14 oz) of tonnarelli. Cook until just shy of al dente, about 2 minutes less than the package time, as it will finish in the sauce.
- 2 Meanwhile, toast the 15 g (1 tbsp) of whole black peppercorns in a dry skillet over medium heat for 1 to 2 minutes until fragrant, then crack them coarsely with a mortar and pestle or the bottom of a heavy pan.
- 3 Place the cracked pepper in a large, wide bowl (metal holds heat best) and add about 80 g (just under half) of the finely grated pecorino. Ladle in 3 to 4 tablespoons of the starchy pasta water and whisk vigorously with a fork to make a smooth, thick paste. The water must be very starchy and the bowl warm, or the cheese will clump.
- 4 Reserve 250 to 350 ml (1 to 1½ cups) of the pasta cooking water, then drain the tonnarelli when it is just shy of al dente.
- 5 Pour the hot drained pasta into the bowl with the pecorino paste and toss rapidly, adding small splashes of the reserved pasta water as needed, until the sauce turns into a glossy, emulsified coating that clings to every strand.
- 6 Stir in the remaining grated pecorino and toss again off the heat for a few seconds so the last of the cheese melts smoothly. If the sauce tightens, loosen it with another tablespoon of hot pasta water.
- 7 Serve immediately in warmed bowls, finishing with a final crack of pepper and a light extra grating of pecorino.
