The Most Authentic Spaghetti Cacio E Pepe Recipe

Spaghetti cacio e pepe is one of the tastiest, comforting and easiest dishes of Roman cuisine. Yet, for as simple as it is, getting this dish right can be hard, and at times even the best restaurants in Italy may end up serving you a cacio e pepe that is less than satisfactory.

I have had all sorts of bad spaghetti cacio e pepe – homemade, or at cheap trattorie. At times they were too dry; other times too salty. Sometimes they were made with egg noodles – which completely changed the flavor; others they were prepared with added butter or oil – which again changes the flavor.

One important thing to know is that there only is one real recipe to make spaghetti cacio e pepe; and it only calls for 3 ingredients: spaghetti, cacio (another way to say cheese in Italian) and pepe (black pepper). Anything else is a poor adaptation you really can do without.

Are you curious to discover how the real cacio e pepe is made, and want to try it at home? Just read on!

How To Make Spaghetti Cacio E Pepe

Use whatever shape of pasta

This is the only change you are allowed to the recipe. Here we either use spaghetti or tonnarelli – but the latter may be hard to come across overseas. Preferably use another kind of long pasta such as linguine or bucatini. Just make sure not to use egg-noodles as they have a much stronger flavor and the final flavor would change too much.

Only use pecorino cheese

I have seen recipes suggesting to use parmigiano cheese, but that is simply poor advice. The only cheese you can use to prepare cacio e pepe is pecorino romano.

There’s no need for oil or butter

The recipe only calls for spaghetti, black pepper and pecorino cheese. If you work the ingredients in the right way, the final texture will be perfectly creamy as is.

In fact, any recipe you see that adds any ingredient other than the 3 mentioned here is not original, and probably made by someone who’s never been to Rome.

Don’t add cream

The creamy texture of the sauce is a result of the masterful whisking of pecorino cheese with cooking water.

Don’t add garlic

I know you guys love your garlic, but despite common misconception not all Italian recipes call for it. This is one of those where garlic would really be an unwelcome ingredient. In other words, do not add it.

Do not add chicken

Sorry guys, but chicken never goes on pasta in Italy. Some very modern restaurants add raw shrimp and in this case, I have to admit the flavor is very interesting!

It’s ok to add some vegetables

Here in Rome we sometimes add thinly sliced, fried artichokes or crispy fried zucchini flowers.

Don’t serve it as a side dish

We don’t have a habit of serving pasta as a side dish in Italy. It’s what we’d normally call a first course – “primo piatto” in Italian.

What’s the best wine pairing?

Both red and white wine can be excellent pairing to a good spaghetti cacio e pepe. If you are a fan of red, I recommend a light red such as a Rosso di Montalcino. If you prefer whites, opt for a Chardonnay.

  4. Ciao Claudia,
    I agree that Pecorino Romano is the “likely” most authentic choice for Cacio e Pepe. It is the “cheese” of and from Lazio. Parmigianno is of the Emilia-Remagna. But the cheese in your photo is not Pecorino Romano, which is much whiter and smoother in texture, no dimpling. I was a Cheesemonger for over 12 years and am most familiar with both cheeses. In our store we carried both Locatelli and Sini Fulvi, one of the last still made in Lazio. And both wheels were covered in a black paper. Definitely not a brown rind like in your photo. I apologize for this comment and most will not notice. I couldn’t help myself!

    The most “authentic” recipe I’ve found called for half Pecorino Romano and half Cacio di Roma, a younger, softer, milder sheep’s milk cheese, also from Lazio.
    Personally I really like half Romano & half Parmigiano. And if you watch Stanley Tucci’s “Searching for Italy” Rome episode, the last scene takes place in a restaurant run by a Japanese chef. Tucci swoons over his Cacio e Pepe and finally the Chef confides his cheese content: 70% Pecorino Romano & 30% Parmigiano-Reggiano.
    I’ve also had in the US an excellent version that was made with Grana Padana and butter. And twice in Rome in Trastevere at “Le Mani in Pasta” delicious versions they told me made with Provolone Picante.
    I love “authentic” but in the end if it reflects the “spirit” of a place and it’s culinary culture and it’s delicious; I can’t complain.
    Enjoyed your recipe, it definitely is “authentic”; well done, David

  5. Thank for your comment! I bought that cheese specifically asking for pecorino romano. I’d dare say that local cheesemongers will know what Pecorino Romano is. I will point out your comment to them and see what they have to say and keep you posted – this is fun! I am glad that you enjoyed the recipe and that you are open to reasonable modifications. Personally, I would never eat a cacio e pepe made with provolone though!

  6. Claudia,
    Provolone comes in different ages. The most commonly available is very young and mild. But Provolone “Piccante” (which in Italian, as you know, means spicy or hot) is much more aged and has a “sharper”, much richer flavor. At Le Mani, in Trastevere, the dish is great. When they told me it was made with Provolone, I found that puzzling and maybe I misunderstood. But I’m sticking with Romano and Parmigiano.
    If I was mistaken about the cheese in your photo and it was Pecorino Romano, I apologize. Never have seen one that looks like that. Ciao

  7. I recently returned from Rome, and I have to say this is THE recipe for Caio e Pepe. Do not add anything else or it’s not authentic. If you want to use butter, cream, and/or parmigiana, just make Alfredo.
