Cacio e Pepe

Silky, peppery pasta with Pecorino Romano, ready in under 25 minutes.

Prep Time:5 minCook Time:15 minTotal Time:20 minServings:2Difficulty:Easy

Cacio e Pepe is the kind of dish that feels simple and brilliant at the same time — three basic ingredients transformed with technique. I love how a few minutes and the right pasta water can turn grated Pecorino and cracked black pepper into a lusciously coating sauce that clings to each strand.

This version is tuned for home cooks: toast the pepper for perfume, reserve just enough starchy pasta water, and whisk quickly to make a creamy emulsion. It’s perfect for a fast weeknight dinner or an elegant, effortless meal for two.

Directions

  1. 1
    Salt being sprinkled into a large pot of boiling water for cacio e pepe

    Bring a large pot of water to a rolling boil and salt it generously with 1 tbsp kosher salt.

  2. 2
    Grated Pecorino Romano beside cracked black pepper toasting in a dry skillet

    While the water heats, finely grate the Pecorino and gently toast the cracked black pepper in a dry skillet over medium heat until fragrant, about 1 minute; remove from heat.

  3. 3
    Spaghetti cooking in boiling water with a cup of reserved starchy pasta water nearby

    Cook the spaghetti until very al dente according to package directions (about 8–9 minutes), stirring occasionally. Reserve 1 1/2 cups of the starchy pasta water before draining.

  4. 4
    Pecorino and hot pasta water whisked into a smooth cheese emulsion

    In a wide bowl or shallow skillet, add 1/2 cup of the reserved hot pasta water and whisk in the grated Pecorino a little at a time to create a smooth, slightly loose emulsion (work quickly to avoid clumping).

  5. 5
    Toasted cracked black pepper being added to the Pecorino cheese emulsion

    Add the toasted cracked pepper to the cheese emulsion and taste for seasoning.

  6. 6
    Cheese and pepper sauce being poured over spaghetti as it is tossed in a skillet

    Return the drained pasta to the pot or a warm skillet set over low heat. Pour the cheese and pepper emulsion over the pasta and toss vigorously, adding more reserved pasta water a few tablespoons at a time until the sauce becomes glossy and evenly coats the strands.

  7. 7
    A pat of butter melting into glossy cacio e pepe spaghetti in a skillet

    If using, stir in the butter for extra silkiness and toss again to combine. Adjust with salt or more cheese to taste.

  8. 8
    Finished cacio e pepe served with extra Pecorino and freshly cracked black pepper

    Serve immediately, finishing each plate with a generous crack of black pepper and a sprinkle of extra Pecorino.

Ingredients

  • Spaghetti:8 oz
  • Pecorino Romano, finely grated:1 1/4 cup
  • Black peppercorns, coarsely cracked:2 tbsp
  • Kosher salt (for pasta water):1 tbsp
  • Unsalted butter (optional, for silkiness):1 tbsp
  • Extra Pecorino for serving:2 tbsp

Tips & Notes

  • Grate the cheese fresh and finely — pre-grated cheese won’t melt smoothly.
  • Work quickly and use hot, starchy pasta water to coax the Pecorino into a creamy emulsion.
  • Toast the pepper lightly to deepen its flavor but don’t burn it — it only needs a few seconds.
  • If the sauce clumps, add a splash more hot pasta water and whisk vigorously to smooth it out.
