First Step: Cook Your Pasta
Bring approximately 3 quarts of water to a rolling boil in a large pot. Salt the water generously with fine sea salt to season the pasta. Add your chosen pasta traditionally spaghetti, bucatini, or tonnarelli and cook until just al dente, stirring occasionally to prevent sticking. Reserve about ⅓ cup (80 ml) of the starchy pasta water before draining.

Second Step: Toast the Black Pepper
While your pasta cooks, melt the butter (if using) in a large sauté pan over medium heat. Add the coarsely ground freshly cracked black pepper and toast it briefly for around 30 seconds to release its fragrant oils. Remove the pan from heat immediately to avoid the pepper burning.

Third Step: Combine Pasta and Sauce Components
Using tongs, transfer the cooked pasta directly from the pot into the pan with pepper and butter, retaining some of the starchy pasta water. Add the reserved pasta water incrementally, tossing the pasta to combine and help dissolve the pepper into a flavorful base for the sauce.

Fourth Step: Incorporate the Pecorino Cheese
Add half of the finely grated Pecorino Romano cheese to the pasta, tossing continuously to coat the noodles evenly and create a creamy texture. Gradually add the remaining cheese while stirring vigorously. Use extra starchy pasta water as needed to maintain a glossy, smooth sauce that clings to the pasta perfectly.

Final Step: Serve Immediately
Once the sauce is silky and coats the pasta beautifully, plate your cacio e pepe. Garnish with additional freshly cracked black pepper and a sprinkle of Pecorino Romano cheese if desired. Serve right away for the best flavor and texture this dish truly shines when fresh.
