Thick hollow pasta drenched in a savory tomato and guanciale sauce, this Roman staple is a hearty mediterranean family meal. The bold flavors of pecorino and pepper make every bite satisfying.
Bring a large pot of salted water to a boil. Add bucatini pasta and cook until very al dente, about 1–2 minutes less than package instructions.
Meanwhile, heat olive oil in a large skillet over medium heat. Add diced guanciale and cook, stirring frequently, until golden and crisp—do not let it burn, adjust heat as needed.
Stir in black pepper and crushed red pepper flakes. Sauté briefly to bloom their flavors; do not toast too long.
Add canned tomatoes to the skillet. Break up tomatoes with a spoon and simmer over medium-low for 10–15 minutes, controlling temperature so sauce thickens but does not dry out.
Drain pasta, reserving some cooking water. Add pasta to the skillet; toss to coat with sauce and adjust consistency using reserved water. Remove from heat, stir in half the pecorino Romano cheese, then season to taste with salt.
Plate the pasta. Sprinkle remaining pecorino on top and serve immediately.
