How to make restaurant-worthy cacio e pepe at home! A bit of butter adds a little fail-safe for emulsifying the sauce (it’s also really tasty). Make sure you have your tongs ready, as continuously tossing the pasta and sauce ingredients is what gets that peppery sauce super creamy and clinging to the noodles.
3 tablespoons extra-virgin olive oil
¾ teaspoon coarsely ground black pepper, plus more for serving
8 ounces dried spaghetti or bucatini (226g)
2 tablespoons unsalted butter, cut into cubes (28g)
2 ounces Pecorino Romano cheese, finely grated on a microplane, 1 heaping packed cup (55g), plus more for serving
1Cook pasta: Bring a pot of salted water to a boil. Add the pasta, and cook to al dente, according to the package instructions, 7 to 10 minutes. I do not drain my pasta, but if you do, reserve 1 cup of it before draining.
2Toast black pepper: Heat the olive oil and black pepper in a wide skillet over medium-low heat. Once the pepper starts to sizzle, turn off the heat and set the pan aside.
3Start sauce: When the pasta is done, add ¼ cup of the hot pasta cooking water to the skillet with the olive oil and pepper. Add the butter cubes. Then use tongs to transfer the pasta to the skillet.
4Toss the pasta: Add the finely grated pecorino cheese, then use tongs to vigorously toss the pasta in the skillet until a creamy, emulsified sauce forms and starts sticking to the noodles. It will look lumpy at first, but keep tossing, adding a little more hot pasta water, a tablespoon at a time, as needed, and it will eventually turn into a thickened, emulsified sauce that coats the noodles.
5To finish: Serve with more Pecorino Romano cheese and fresh ground black pepper on top. A pinch of flaky sea salt and a drizzle of olive oil is lovely, too.
