What is Bucatini?
Long hollow spaghetti from Lazio -- the thin central channel fills with sauce during cooking so each bite delivers sauce from the outside and inside simultaneously.

Bucatini is a long, thick pasta from Lazio, identical to spaghetti in format but with a narrow channel running through the center of each strand. Each piece is approximately 25-30cm long and 3mm in diameter, with a hollow bore running its full length. The name comes from buco, Italian for “hole”; the related form bucato means “pierced.” In the Naples area and parts of Campania the same shape is called perciatelli, from the Neapolitan perciato — also “pierced” — and the two names coexist in Italian and international markets. Bucatini is made from hard durum wheat flour and water and is almost always sold dried.

The hollow center of bucatini acts as a sauce reservoir: liquid sauce enters the tube during cooking and is released with each bite, delivering flavor simultaneously from the outside coating and the inside channel. This mechanism means bucatini carries more sauce per bite than solid spaghetti of similar diameter. The effect is most pronounced with liquid-rich sauces where rendered fat emulsifies with starchy pasta water — the mixture enters the bore and concentrates there.
Amatriciana — guanciale (cured pork jowl), tomato, pecorino romano, and dried chili — is the canonical Roman pairing. The fat rendered from guanciale during cooking emulsifies with tomato juice and pasta water into a glossy sauce that is thin enough to enter the bore yet viscous enough to coat the exterior. The specific combination of fat, acid, and starch makes amatriciana technically well-suited to bucatini in a way that chunkier, drier sauces are not.
Pasta alla gricia — guanciale and pecorino romano without tomato, which was introduced only after the Columbian Exchange — is an older preparation that works by the same principle. The rendered guanciale fat and the pasta’s starchy cooking water emulsify under constant tossing into a sauce that enters the hollow and coats every surface. Gricia is sometimes described as the ancestor of both amatriciana (add tomato) and carbonara (add eggs), and bucatini suits all three preparations for the same mechanical reasons.
Buttery sauces, anchovy and sardine preparations, and vegetable-based ragus also work with bucatini’s hollow structure. The greater thickness of bucatini compared to spaghetti means a more substantial chew and a cooking time of 9-11 minutes — longer than spaghetti — that the sauce can penetrate before serving.
Bucatini is produced by extrusion through perforated disks, similar to the mechanism of a meat grinder, which forces the dough into long tubes that are then cut to length and either cooked fresh or dried. The hollow was historically a practical production benefit before it became a culinary one: thick pasta strands develop cracks during drying if the center dries faster than the exterior. The hollow bore allows the interior surface to dry at the same rate as the exterior, preventing the stress fractures that plague large solid cylinders. The culinary benefit of sauce delivery through the hollow was a secondary discovery.
Bucatini is documented in Lazio from the 19th century and is associated almost exclusively with Roman cuisine. Outside Lazio and Campania — where perciatelli is the local name — the shape is uncommon in Italian regional cooking. It appears rarely in Emilia-Romagna, Tuscany, or northern Italy, where the long-pasta tradition centers on egg-based ribbon shapes like tagliatelle and pappardelle rather than durum semolina extrusions. This regional concentration makes bucatini and its Roman preparations one of the clearest examples of a shape inseparable from its home cuisine.
Bucatini measures approximately 25-30cm in length with a 3mm diameter, making it substantially thicker than spaghetti. The central hollow bore — the defining structural feature — requires extrusion through a perforated disk similar to a meat grinder, which forces the dough into long tubes that are then cut to length. Historically, the hollow was a practical drying benefit that prevented the stress fractures plaguing large solid cylinders, though it became a culinary advantage once its sauce-delivery mechanism was understood. Bucatini cooks in approximately 9 minutes when dried, longer than solid spaghetti due to its greater diameter.
The canonical Roman preparation is bucatini all’amatriciana, featuring guanciale (cured pork jowl), tomatoes, and pecorino cheese. Guanciale, softer and fattier than pancetta, produces a richer sauce when rendered. Pasta alla gricia — guanciale and pecorino alone, without tomato — is an older preparation that works by the same fat-and-starch emulsion principle, and is sometimes described as the ancestor of both amatriciana and carbonara. In Naples and parts of Campania, bucatini is called perciatelli, from the Neapolitan word perciato (pierced), and the two names coexist in Italian and international pasta markets.
Amatriciana originates from Amatrice, a town in Lazio north of Rome in the agricultural area of the Gran Sasso mountain range. The sauce evolved from an earlier white-sauce preparation (gricia) before tomatoes became available; Roman cook Francesco Leonardi documented an amatriciana preparation in his 1790 cookbook, and the dish reached Rome with Amatrice migrants in the 19th century. Bucatini appears throughout Italy from north to south, but is particularly prominent in the south; when cooked just to the bite, its texture stands up well to stronger-tasting sauces, though its hollow middle requires careful monitoring to prevent overcooking.
Spaghetti is the obvious comparison: both are long, round-profile strands of durum semolina in the 25-30cm range, with overlapping sauce pairings and cooking contexts. Spaghetti is solid and typically 1.8-2mm in diameter; bucatini’s 3mm diameter plus the hollow bore makes it a thicker, more substantial strand with a different mechanical relationship to sauce. Amatriciana, cacio e pepe, and carbonara all have spaghetti versions and bucatini versions in Roman cooking; bucatini is considered the more traditional pairing for amatriciana specifically.
Linguine is the flat equivalent: a long, narrow strand with an oval cross-section that suits similar sauce types — lighter oil-based and seafood sauces — but lacks the hollow center. Where bucatini delivers sauce from inside the strand, linguine relies entirely on surface coating.
