One of the simplest and most beloved pasta dishes from Rome, cacio e pepe literally translates to “cheese and pepper.” Pronounced kaa-chee-ow-ee-peh-pay, the traditional dish calls for just three ingredients: coarsely ground black pepper, finely grated Pecorino Romano, and pasta. Some modern versions, like this one, add a little olive oil, butter, or cream for extra richness. The magic happens when starchy pasta water is mixed in, creating a rich, creamy sauce that clings to the pasta—think of it as Italy’s version of mac and cheese, similar in its simplicity to fettuccine Alfredo, but with a bold, peppery kick.

The traditional method involves stirring cheese and pasta water into cooked noodles, but it’s prone to clumping. To avoid this, I use a trick from Luciano Monosilio: blend the pasta water and cheese first to achieve a smooth, velvety sauce. Perfect for two, this cacio e pepe recipe is a quick, no-fuss meal, but can easily be doubled if needed!

What You’ll Need To Make Cacio e Pepe

ingredients for cacio e pepe
  • Pasta: The recipe calls for bucatini, spaghetti, or tonnarelli. Bucatini (also known as perciatelli) resembles spaghetti but is thicker and has a small hole running through the center—hence the name “buco,” which means “hole” in Italian. Tonnarelli, on the other hand, is a long, thick pasta with square edges, traditionally used in Roman cuisine and ideal for soaking up rich sauces. Spaghetti is a great alternative if you can’t find the other two.
  • Pecorino Romano: A sharp, salty sheep’s milk cheese that provides bold flavor. It’s the best choice for this dish, as it adds more intensity than Parmesan or Parmigiano-Reggiano. Pre-grated cheese is perfectly fine to use in this recipe—that’s what I use!
  • Freshly Ground Black Pepper: Use coarsely ground pepper for the best texture and flavor. I’ve given a range depending on how peppery you like your pasta; add to taste.
  • Butter: While not a traditional ingredient in cacio e pepe, the butter is used to “bloom” the fresh ground pepper before mixing it in with the pasta. It also makes for a creamier sauce without diluting the other flavors.

Servings: 2
Prep Time: 5 Minutes
Cook Time: 20 Minutes
Total Time: 25 Minutes

Ingredients

  • Salt
  • 8 oz bucatini, spaghetti, or tonnarelli
  • 2 tablespoons unsalted butter
  • 1½ - 2 teaspoons freshly ground black pepper, depending on how peppery you like your pasta
  • 1 cup finely grated Pecorino Romano cheese

Instructions

  1. In a Dutch oven or large pot, bring 2 quarts of water and 1 teaspoon of salt to a boil. Add the pasta and cook according to package instructions until al dente. Reserve 1 cup of the pasta cooking water and drain.
  2. Set the same pot over low heat and melt the butter. Add the pepper and cook, stirring constantly, until fragrant, about 1 minute. Add the drained pasta to the pot and toss to coat evenly. Remove the pot from the heat.
  3. In a blender, combine the cheese and ⅔ cup of the pasta cooking water. Blend until smooth and creamy, 10 to 15 seconds. Add the sauce to the pasta in the pot and toss with tongs. Place the pot back over low heat and cook, stirring constantly with the tongs, until the sauce is the consistency of a thin cream sauce, a few minutes. Add more of the reserved pasta water to thin the sauce only if necessary. Be careful at this stage: if the sauce gets too hot, it will start to clump up and stick to the pot and tongs. Once the sauce is the right consistency, immediately transfer the pasta to bowls and serve. Pass more cheese and pepper at the table, if desired.

  • Hi Jenn,
    This recipe calls for 1cup Pecorino Romano. I always try to weigh my ingredients when practical. I was wondering what the weight of 1c of cheese would be. Typically, an 8oz block of cheese yields 2 cups. Following that, would I use 4oz of cheese in this recipe.
    Please advise. Thanks!

      • Hi Jenn,
        Thanks for the info and your quick response. I did use close to 4 oz., but as you suggested, I could have gotten by with ~3.5 ounces/99 g. This recipe was great and will definitely be made again, next time using 3.5 oz.

    • Hi Denise, Unfortunately, you really need a blender for this. If you have a food processor, that would work too.
