A classic Roman pasta featuring bucatini coated in a glossy sauce of slow-rendered guanciale, sweet tomatoes, chilli and sharp Pecorino Romano. This refined version focuses on traditional ingredients while adding modern technique guidance for reliable home cooking.
Bring a large pot of salted water to the boil. Grate the Pecorino Romano, crush the tomatoes, and cut the guanciale into strips.
Having everything ready allows the sauce to be built quickly once the guanciale begins cooking.
Guanciale pieces should be thick enough to stay tender after rendering.
Place guanciale in a cold frying pan and cook over medium-low heat for 10-15 minutes until the fat has rendered and the edges are golden. Remove some pieces for finishing if desired.
Slow rendering extracts flavourful pork fat that becomes the foundation of the sauce.
The guanciale should be golden and crisp at the edges but not burnt.
Add chilli flakes to the rendered guanciale fat and cook briefly for 20-30 seconds.
Heating the chilli in fat releases its aromatic oils and distributes the heat evenly.
The fat should smell fragrant without the chilli darkening.
Add the crushed tomatoes to the pan and simmer uncovered for 20-25 minutes until reduced and glossy.
Reduction concentrates the tomato flavour and creates a sauce that can coat the pasta.
The sauce should be thick enough to cling to a spoon.
Boil the pasta until 1-2 minutes short of al dente. Reserve pasta water before draining.
The pasta finishes cooking in the sauce, allowing the starch to help create a smooth texture.
The pasta should still have a firm centre.
Add bucatini to the sauce and toss vigorously with pasta water until glossy. Remove from heat and mix in Pecorino Romano. Finish with black pepper and the reserved guanciale.
Final emulsification combines tomato, pork fat, cheese and starch into a cohesive sauce.
The sauce should cling tightly to the pasta without pooling.
