I was a skeptic, but now I’m a believer in this simple, unusual method. This is truly a no-fail recipe for the Italian classic pasta, Bucatini Cacio e Pepe.

Bucatini Cacio e Pepe served in an ivory ceramic bowl.

If you’ve tried to make this dish in the traditional way and ended up with blobs of cheese and watery pasta, you’re not alone (ahem). You’ll see a lot of recipes that try to remedy this problem with oil, butter, cream or even cornstarch added to the sauce. But I’m here to promise you, there’s an easier way.

Bucatini Cacio e Pepe Ingredients

  • Freshly Ground Black Pepper: lots of it!

What is Cacio e Pepe?

Cacio e Pepe, meaning “cheese and pepper” in Italian, is a classic pasta dish that originated in Rome. It’s made with black pepper, grated Pecorino Romano cheese and long, slender pasta like spaghetti or, in this case, bucatini.

Making this dish traditionally means adding freshly boiled pasta to a bowl of grated pecorino and black pepper and stirring it together along with some of the hot, starchy pasta water. In theory, the heat melts the cheese and the starches of the cooking water bind the pepper and cheese to the pasta, creating a creamy sauce. This method does work, occasionally. But too often it doesn’t.

The No-Fail Method

I wish I could claim credit for this no-fail method of making Bucatini Cacio e Pepe, but I heard it from Deb Perelman, who heard it from “Annie” that Elizabeth Minchilli had written about it and captured restaurateur Flavio de Maio demonstrating how to do it on video. Phew. So here’s the method.

You simply whirl the pecorino cheese and black pepper in a food processor with some cold water to create a thick paste and toss that with hot pasta and cooking water (Flavio de Maio makes it with an immersion blender). The one thing I’m adding to the conversation is to create the sauce in the serving bowl, by stirring some of the hot, starchy pasta water into the cheese and pepper mixture, just a minute before adding the drained pasta. It makes this method even easier.

How to Make Bucatini Cacio e Pepe

Bring a large pot of water to boil. Meanwhile, combine pecorino Romano, black pepper and 5 tablespoons of cold water in a food processor and process until very smooth, scraping the sides as necessary.

While you cook bucatini according to package directions, transfer cheese mixture to a large serving bowl. With 1 minute left in the cooking time, scoop out 1/2 cup pasta water and add 3 tablespoons, one at a time, to the cheese mixture while quickly stirring until you have a smooth sauce.

Drain pasta and add to sauce in serving bowl; toss quickly to coat, adding more pasta water if necessary to loosen. Divide among 4 bowls; finish with more pecorino and black pepper and serve right away.

    Interesting idea! We make cacio e pepe here on the regular, but I’ll have to try this version with the food processor next time.

    I love pasta Cacio e Pepe. I honestly don’t remember if I’ve ever had any issues with (not) melting cheese, but I like the method you suggest here. The pasta sauce looks perfectly silky and smooth!
