Cacio e Pepe ingredients

  • 12 oz Spaghetti or Tonnarelli pasta
  • 1.5 cups pecorino romano cheese
  • 2 tbsp black peppercorns
  • 2 tbsp unsalted butter
  • as needed salt

How to make Cacio e Pepe

  1. Grate 1.5 cups of Pecorino Romano cheese finely. For the best emulsion, grate about 1 cup into a bowl, then keep the remaining 0.5 cup separate for finishing.
  2. Coarsely crack or grind 2 tablespoons of black peppercorns. Heat a dry, large skillet over medium heat and toast the cracked black pepper for 1-2 minutes until fragrant, being careful not to burn it. This intensifies the pepper's flavor.
  3. Add 2 tablespoons of unsalted butter to the skillet with the toasted pepper, allowing it to melt completely over low heat, infusing the butter with the peppery aroma.
  4. Bring a large pot of water to a boil. Add salt, but be mindful as Pecorino Romano is already salty. Add 12 oz of spaghetti or tonnarelli pasta and cook until very al dente, about 2 minutes less than package directions. It will finish cooking in the sauce.
  5. Before draining the pasta, reserve 1.5-2 cups of the starchy pasta cooking water. This starchy water is crucial for creating the creamy sauce.
  6. Transfer the al dente pasta directly into the skillet with the butter and pepper, using tongs. Add about 1 cup of the reserved pasta water to the skillet.
  7. Increase the heat to medium-high and vigorously toss the pasta for 1-2 minutes, allowing the pasta to absorb the peppery butter and release more starch into the water, creating a rich base for the emulsion.
  8. Remove the skillet from the heat. Gradually add the grated Pecorino Romano cheese (the 1 cup portion) to the pasta, tossing continuously with tongs. Add more pasta water, a splash at a time, as needed, while continuing to toss. The goal is to create a creamy, emulsified sauce that coats every strand of pasta, not a clumpy mess.
  9. Keep tossing and adding small amounts of pasta water until the sauce is glossy and smooth. If the sauce becomes too thick, add a little more hot pasta water; if too thin, add a little more cheese (from the remaining 0.5 cup).
  10. Serve immediately, dividing the Cacio e Pepe among warm plates. Finish each serving with an extra sprinkle of the remaining grated Pecorino Romano and a fresh grind of black pepper, if desired.
