A classic Roman pasta dish that's surprisingly simple to make, yet incredibly flavorful. Perfectly cooked pasta is tossed in a creamy, peppery sauce made with Pecorino Romano cheese and black pepper.
Bring a large pot of salted water to a rolling boil.
Add the spaghetti to the boiling water and cook according to package directions until al dente.
While the pasta is cooking, toast the freshly ground black pepper in a dry skillet over medium heat for about 1-2 minutes, until fragrant. Be careful not to burn it.
In a large bowl, combine the grated Pecorino Romano cheese and the toasted black pepper. Add about 0.5 cup of the hot pasta water to the cheese mixture and whisk vigorously until a smooth, creamy paste forms. You may need to add a little more pasta water to achieve the desired consistency.
Once the pasta is al dente, reserve about 1 cup of the pasta water before draining. Drain the pasta well.
Add the drained pasta directly to the bowl with the cheese and pepper mixture. Toss quickly and continuously, adding more reserved pasta water a tablespoon at a time, until the pasta is well coated and the sauce is creamy and emulsified. Work quickly to prevent the cheese from clumping.
Serve immediately, with an extra sprinkle of Pecorino Romano cheese and black pepper, if desired.
Notes
For an even creamier sauce, you can add a tablespoon of unsalted butter to the cheese mixture.
