Instructions
Preparation Steps
Bring a large pot (about 4 quarts) of water to a boil. Add the kosher salt.
Finely grate the Pecorino Romano until powdery. Grind the black pepper.
In a large skillet, toast the ground black pepper over medium heat for 0.5 to 1 minute until fragrant; do not burn.
Cook the spaghetti until just shy of al dente. Before draining, reserve at least 1.5 cups of the hot, starchy pasta water.
Ladle about 1.0 cup of the reserved pasta water into the skillet with the toasted pepper. Simmer for 1 to 2 minutes to infuse and reduce slightly.
Transfer the spaghetti to the skillet. Toss vigorously over medium heat until the pasta is coated and glossy, about 1 minute.
Remove the skillet from the heat. Sprinkle in the Pecorino a handful at a time, tossing constantly and adding splashes of the remaining hot pasta water as needed until a silky, creamy sauce forms and clings to the pasta.
Serve immediately with extra Pecorino and black pepper to taste.
Notes
For best results, use very finely grated Pecorino Romano and add it off the heat. If the sauce looks tight or clumpy, add a bit more hot pasta water and toss vigorously until smooth. Work quickly and serve right away.
