Spaghetti alla Gricia

1. Boil Water

Begin by bringing 6 quarts of water to a vigorous boil in a large pot. Once the water reaches a rolling boil, generously season it with 3 tablespoons of kosher salt. This step ensures your pasta is perfectly seasoned from the inside out.

2. Cook Guanciale and Onions

While the water is heating, heat ¼ cup of extra virgin olive oil in another large pot over medium heat. Add the 4 ounces of sliced guanciale (or pancetta or bacon), and the sliced red onion. Cook, stirring occasionally, for about 7 minutes, until the guanciale is lightly browned and the onions are softened. The fat rendered from the guanciale will impart a rich, savory flavor to the onions, creating a delicious base for your sauce.

3. Add Black Pepper

Stir in 1 tablespoon of coarsely ground black pepper into the guanciale and onion mixture. This will add a warm, peppery kick that balances the rich flavors of the dish.

4. Cook Spaghetti

As the guanciale and onion cook, add 1 pound of spaghetti to the boiling water. Cook the pasta until it is al dente, which should take about 8-10 minutes. Be sure to check the pasta a couple of minutes before the package instructions suggest; you want it to be firm to the bite.

5. Combine Pasta with Sauce

Once the pasta is ready, reserve ¼ cup of the pasta cooking water before draining. This starchy water is key to helping the sauce adhere to the pasta. Add the drained spaghetti to the pot with the guanciale and onions, along with the reserved pasta water. Toss everything together until the pasta is well coated with the flavorful mixture.

6. Add Cheese and Parsley

Stir in ½ cup of freshly grated Parmigiano-Reggiano, ½ cup of grated pecorino romano, and ⅓ cup of coarsely chopped fresh Italian parsley. The cheeses will melt into the hot pasta, creating a creamy, cohesive sauce, while the parsley adds a fresh, herbaceous note to the dish.

7. Serve

Serve the spaghetti immediately, with additional grated Parmigiano-Reggiano on the side for sprinkling. Enjoy your Peppery Guanciale and Onion Spaghetti, a dish that is sure to delight with its robust flavors and satisfying textures.
