This authentic-style bucatini with tomato, guanciale and chilli is a punchy, high-protein pasta dish that expertly balances heat and salt. The secret lies in the unconventional preparation of the rosemary, which is dried and ground into a fine powder to infuse the tomato sauce with a subtle, woodve fragrance. Using guanciale provides a deeper, silkier fat than standard pancetta, creating a glossy sauce that clings perfectly to the thick, hollow strands of bucatini.
Ideal for a weeknight dinner that feels like a treat, this recipe is a sophisticated take on the classic Amatriciana. The combination of slow-cooked onions, spicy red pepper flakes and sharp Pecorino cheese creates a deeply savoury profile. Serve it in warmed bowls with an extra drizzle of cold-pressed olive oil for a truly restorative homemade meal.

How to make Bucatini with Tomato, Guanciale, and Chilli
Back to contentsMicrowave rosemary on high in 20-second intervals until leaves are brittle, about 60 seconds. Remove leaves and grind to a fine powder with a spice mill or mortar and pestle; you should have about 1 teaspoon (Alternatively, very finely chop leaves.)
Cook guanciale in a large skillet over medium heat, stirring often, until guanciale is browned and crisp, 10–12 minutes. Transfer to a bowl with a slotted spoon.
Cook onion in same skillet over medium heat, stirring often, until softened and golden brown, 8–10 minutes. Return all but 2 tablespoons guanciale to skillet and add tomatoes, red pepper flakes, and rosemary powder. Bring to a boil, reduce heat, and simmer, stirring occasionally, until sauce is thickened, 5–8 minutes.
Meanwhile, cook pasta in a large pot of boiling salted water, stirring occasionally, until al dente, 8–10 minutes. Drain pasta, reserving 240ml pasta cooking liquid
Add pasta and 120ml pasta cooking liquid to sauce. Cook over medium heat, tossing and adding more cooking liquid as needed, until sauce coats pasta, about 2 minutes.
Serve pasta topped with Pecorino and remaining 2 tablespoons guanciale and drizzled with oil.
