A cornerstone of Roman trattoria cooking, this iconic pasta unites crisp-rendered guanciale, sweet San Marzano tomato, and sharp Pecorino Romano in a glossy, deeply savory sauce. It comes together in under 40 minutes but tastes like it has been simmering all afternoon.

Ingredients
For the sauce
- 2 tbsp extra-virgin olive oil
- 1 medium yellow onion, finely diced (about 1 cup)
- 6 oz (170 g) guanciale, cut into 1/4-inch matchsticks
- 1/2 tsp dried red pepper flakes
- 1/2 cup (120 ml) dry white wine
- 1 (28 oz / 794 g) can whole San Marzano tomatoes, hand-crushed
- 3/4 tsp fine sea salt, plus more to taste
- Freshly cracked black pepper, to taste
For finishing
- 1 lb (450 g) spaghetti or bucatini
- 2 tbsp kosher salt for the pasta water
- 1 cup (90 g) freshly grated Pecorino Romano, plus extra for serving
Directions
- Bring a large pot of water to a rolling boil, salt it generously (it should taste like the sea), and have the pasta measured out and ready to go.
- Meanwhile, warm the olive oil in a 12-inch skillet over medium-low heat. Add the onion and cook gently, stirring often, until soft and translucent, 6 to 8 minutes; do not let it brown.
- Raise the heat to medium and add the guanciale. Cook, stirring occasionally, until the fat has rendered and the pieces are golden and crisp at the edges, 6 to 7 minutes. Stir in the red pepper flakes for 30 seconds.
- Pour in the white wine and scrape up any browned bits from the pan. Simmer until almost fully evaporated, about 2 minutes.
- Add the hand-crushed tomatoes and salt. Simmer the sauce gently, uncovered, for 12 to 15 minutes, until thickened and the raw tomato edge has cooked off. Taste and adjust seasoning.
- Drop the pasta into the boiling water and cook 1 minute shy of the package directions for al dente. Reserve 1 cup of starchy cooking water before draining.
- Add the drained pasta to the skillet along with 1/2 cup of the reserved pasta water and 3/4 cup of the pecorino. Toss vigorously over medium heat for 45 to 60 seconds until the cheese melts into a glossy emulsion that clings to every strand.
- Loosen with more pasta water as needed until the sauce coats the noodles like cream. Season generously with black pepper.
- Divide among warm bowls, shower with the remaining pecorino, and serve immediately with extra cheese passed at the table.
Cook’s Notes
- Purists from Amatrice skip the onion entirely; if you want the original, omit it and render the guanciale in olive oil only.
- If guanciale is unavailable, use high-quality pancetta, but never bacon: its smoke will bulldoze the delicate sauce.
- Bucatini is the most traditional shape because its hollow core traps the sauce; spaghetti or rigatoni are excellent substitutes.
- Always reserve more pasta water than you think you need; the starchy liquid is the key to a silky, emulsified sauce.
- Add the cheese off the heat for a moment before returning to a gentle flame to prevent clumping or graininess.
