Creating this incredible dish is straightforward. Follow these simple steps to prepare Bucatini all’Amatriciana:

1. Boil Water: In a large pot, bring salted water to a rolling boil.
2. Cook Bucatini: Add bucatini pasta to the boiling water. Cook according to package instructions until al dente (usually about 10-12 minutes).

8. Combine: Add the drained pasta to the skillet with the sauce. Toss to coat, adding reserved pasta water a little at a time if needed to achieve desired sauce consistency.
9. Finish with Cheese: Remove from heat, then stir in freshly grated Pecorino Romano cheese until melted and incorporated.
10. Serve Hot: Transfer to serving plates and top with extra Pecorino Romano if desired.
