Bucatini alla Gricia

Bring a large pot of very lightly salted water to a boil. Cook bucatini in the boiling water, stirring occasionally, until almost tender yet still pretty firm to the bite, 8 to 10 minutes.

Meanwhile, heat oil in a large nonstick skillet over low heat. Add guanciale and cook slowly until it has rendered all its fat and is crispy on the outside and soft on the inside, 8 to 10 minutes.

Drain bucatini and reserve cooking water.
