Ingredients
- 2tablespoons whole black peppercorns
- 7½ounces/4¼ cups finely grated Pecorino Romano, plus more for serving
- 3⅓ounces/1⅓ cups finely grated Parmigiano-Reggiano
- 1pound dried tonnarelli, spaghetti (regular or thick) or long fusilli
Preparation
- Step 1
Bring a large pot of water to a boil. (Do not add salt.)
- Step 2
Meanwhile, in a very large nonstick skillet or pot set over high heat, toast the peppercorns just until fragrant. Let cool, then grind or crush very coarsely. Reserve 1 teaspoon for serving.
- Step 3
In the same skillet or pot, combine the cheeses and remaining pepper. Add 1½ cups warm water and stir to make a thick pecorino cream.
- Step 4
Add the pasta to the boiling water and stir. Keep the heat very high until the water returns to a boil, then stir again and adjust the heat as needed to keep the water bubbling. Set a timer for 8 minutes.
- Step 5
Set the pecorino cream over very low heat. When the timer goes off, scoop out about ½ cup of the pasta cooking water and set aside. Taste the pasta and continue cooking until the pasta is done to your liking. Drain pasta very well (this is important, as adding too much hot water can cause the cheese to clump) and add to the pecorino cream.
- Step 6
Use tongs or two forks to stir, turn and toss the pasta in the sauce over low heat until the cheese melts and the sauce becomes sticky. Don’t add any water yet, just keep tossing. To test, squeeze a drop of sauce between your thumb and finger. When the sauce is thick and forms strings like glue, it is ready. If it starts to dry out, add cooking water, 1 tablespoon at a time, and toss thoroughly before adding more.
- Step 7
Divide among 4 bowls, twisting the pasta into a nest, if desired. Dust with additional pecorino and the reserved pepper. Serve immediately.

Don’t be fooled by the small number of ingredients. Achieving a creamy, clump-free cacio e peoe is nearly impossible due to the extremely narrow temperature range required for success, Fortunately there is an easy trick. Whisk together a cup of water and perhaps a Tbs of cornstarch and heat until thickened. Then add your pasta water and cheese and you will get a perfect emulsion every time. Yes, I suppose it’s cheating, but my understanding is that even restaurants do this.
Measuring cheese in a cup is a fools errand. There is just too much variation in graters. Then how loosely do you pack it? Just weigh the cheese.
This dish has a tendency to seize up and become a big mess. I suggest googling Ethan Chlebowski's video for his foolproof, scientific preparation method. It's been successful for me both times I've made it.
This is an awful recipe. Sticky clumpy terrible mess. Remove it.
The biggest failure in the instructions for this recipe is stating to use the same pot or pan that one just used for toasting the peppercorns…. Has to cool to room temperature first.
This just didn’t work. I followed instructions to the letter and it was a gloppy, watery mess. You’re better off getting into Roscioli and enjoying it there—otherwise it’s a massive waste of cheese!
