The remarkable thing about cacio e pepe is it’s made with just five very simple ingredients that when combined together create the creamiest, dreamiest bowl of pasta! There’s nothing simple about the flavors in this dish, nutty, aged pecorino, and parmesan cheese, butter, and lightly toasted cracked black pepper meld together to create a creamy sauce that perfectly coats thick, chewy bucatini pasta!

I love using bucatini for cacio e pepe. Bucatini is a thick noodle that looks just like spaghetti but it has a small hole running through it which gives it a unique bite and also gets filled with sauce, yum! You could also use thick spaghetti or tonnarelli which is the traditional pasta for Cacio de Pepe in Rome, Italy where the dish was invented. Sadly, I have yet to see tonnarelli in American supermarkets, until then bucatini it is!

Something to keep in mind when making this recipe is that cacio e pepe is really only as good as its ingredients so spring for the good stuff! Grate your own cheese, buy high-quality European butter, and most importantly, use freshly cracked black pepper, no pre-ground pepper, ever!

  • 10 oz bucatini
  • 4 tbsp butter
  • 1 tbsp freshly cracked black pepper
  • 3/4 c freshly grated Parmesan cheese
  • 1/3 c freshly grated pecorino cheese


  • Bring a large pot of water to a boil and season with salt. Once boiling, add the bucatini and cook, stirring occasionally, until al dente. Reserve 1 cup pasta cooking water before draining.
  • While the pasta is cooking melt half the butter in a large skillet over medium heat. Add the cracked black pepper and cook, stirring occasionally, until toasted, about 2 minutes.
  • Add 3/4 cup of the reserved pasta water to the skillet and bring to a simmer. Next, add the bucatini and remaining butter. Reduce the heat to low and add the cheese, stirring and tossing with tongs until melted and the sauce coats the pasta, add more pasta water if the sauce seems dry. Divide between bowls, top with extra black pepper, and grated cheese. Serve immediately.


  • Bucatini: Substitute spaghetti if needed. 
  • Pecorino and Parmesan: Freshly grated cheese is important for a smooth and creamy sauce. Pre-grated cheese can leave your sauce grainy.
Storing and Reheating:
  • Leftovers can be stored in the refrigerator for up to four days. Reheat in the microwave or stovetop with a few tablespoons of water to loosen up the sauce.
