How to make Spaghetti Cacio e Pepe like a Roman

Cacio-e-Pepe-7

It took me years to make a decent Cacio e Pepe, one of Rome’s traditional pasta dishes (the others are Carbonara, Matriciana, and Gricia).

Since Cacio e Pepe has only three main ingredients -Pecorino Romano cheese, black pepper and pasta-, it might seem an easy recipe to make – but it isn’t.

One of the things I learned  from Italian cooks is that the most difficult recipes are the simply ones – the ones with less  ingredients. For example,  if you want  to cook a superb Pasta al Pomodoro, you need to get high quality tomatoes –and choose the right type like San Marzano- , otherwise you will end up with a soggy sauce.  Also, to get the right consistency, cooking time  is crucial to let excess water evaporate from the sauce.

As regards to Cacio e Pepe, the quality of ingredients, quantities and timing must be considered to get good results. But first, let me get something straight –  Cacio e Pepe does NOT  have:

  • Heavy cream
  •  Any vegetable oil
  • Butter
  • Margarine
  • Milk
  • Parmigiano Reggiano

So how come it has that creamy consistency ? See the recipe below…

Parte 1

Parte 2

Ingredients

  • 400 grams of Spaghetti (if you can find Tonnarelli better)
  • About 200-250 grams of high quality Pecorino Romano cheese (the more aged the better)
  • Black pepper to taste (better if freshly ground)
  • Coarse salt (yes you will need some even though Pecorino Romano has lots of salt, otherwise the dish will be bland)

Method

  1. Grate Pecorino Romano cheese.
  2. In the meantime bring water to a boil in a tall pot.  The level of water should not exceed ¾ of the pot’s height. Keep in mind that for 100 grs of pasta, you should use 10 grs of salt and 1 liter of water.
  3. When water boils, add salt. Consider that Pecorino Romano cheese is very salty, therefore, my advice is to add HALF of the amount of salt for cooking Cacio e Pepe.
  4. Add pasta and cook al dente.
  5. 1-2 minutes before pasta is cooked, place a serving bowl on top of the pot to heat it. This is a very important step in order to get a creamy sauce.
  6. Reserve some pasta water using a ladle. While you’re boiling spaghetti, the pasta releases starch into the water.  Since starch is naturally sticky, it helps Pecorino Romano cheese fats to amalgamate well with both water and pasta.
  7. Drain pasta and transfer it to the heated serving bowl.
  8. Gradually add Pecorino Romano cheese and water tossing vigorously until you get a creamy consistency.
  9. If the sauce becomes too watery, add Pecorino Romano cheese; if it becomes too dry, add water.
  10. Season with lots of freshly ground black pepper and toss.

  5. Oftentimes the simple dishes are easiest to get wrong. One can notice a mistake far easier. A well-made dish of cacio e pepe is a thing of beauty and, Ambrosiana, you certainly did achieve that. The serving in your photo looks perfect! All that’s missing is its intoxicating aroma. Brava!

  18. Seems to me the fewer the ingredients, the more difficult to get it ‘just right’! The thing is, you’ve had the time to refine your tastebuds as well as experiment – lucky us! 🙂

    Just made this, per instructions. Sooo delicious!! I was eating it out of the bowl before it reached the table! Also, just a note: I reserved quite a bit of the pasta water, and was glad I did, since it took more liquid than I expected.

    June 27, 2013
  21. Sarvi #

    I was not able to achieve a sauce — I made half the recipe and reserved about 3/4 cup of pasta water — any suggestions? Maybe I should have reserved more water? Possibly, did I add the cheese too fast? It seemed the cheese was clumping rather than melting. Many thanks for any suggestions.

    July 20, 2013
    • Hi! First of all make you got good quality Pecorino Romano cheese. Also reserve enough pasta water (2 cups at least) to make sure you have enough for tossing pasta. Be sure to heat your mixing bowl, and that water is still hot. Don’t wait too long before spaghetti cools down. First add cheese and then pasta water, toss vigorously until you get a creamy consistency. Add more cheese if it is too watery; add pasta if it is too dry. Hope this helps!

      I know everyone says do not make it with cream or butter, but I also read somewhere that the pecorino they use in Italy has more fat than what we use here. Maybe that’s wrong. But I get the best results by putting none even a teaspoon of heavy cream or half n half in it. Fine, go ahead and say it’s blasphemy. I cant imagine that tiny drop will affect anything except to make the texture more achievable for home cooks. Also – all these comments say “can’t wait to try;” almost none say they actually tried it and it worked. I think that speaks for itself

      January 9, 2022
      • I think you should do whatever it works best for you. If that teaspoon of heavy cream gives you the desired result, great. I am very conscious that outside of Italy it is difficult to find the same quality of certain products. That is, I do not expect to find Pecorino Romano “Brunelli” in Miami for example.

        January 9, 2022
  22. Most of the of best places I had this in roma it was not this creamy, it was always pilled on fresh grated. This seems more like american melted mac and cheese. Nothing wrong with this, I dont want to be recipe police, but people shouldn’t worry about getting it this melted with adding water. If you use really fresh good pasta which is so important on this recipe it wont be dry, and if you get fresh cut pecorino, its not that dry either. I would assume that if you use dried out pecorino or dried pasta you might need to add water to make it creamier.

    September 9, 2013
    • Hi thanks for visiting my blog! Most of the best trattorias in Rome do serve Cacio e Pepe with a creamy sauce. Some trattorias do serve it with lots of grated Pecorino Romano Cheese. Water is always used either with dry pasta (packaged spaghetti), or Tonnarelli (fresh pasta), so it doesn’t matter. As far as the quality of Pecorino Romano, the aged the cheese, the better. Here is a link of Felice in Testaccio, voted by Romans as the best Cacio e Pepe in Rome.You could see that their Cacio e Pepe is creamy. http://www.feliceatestaccio.it/menu.html

        I like your response, and more than that your blog.

        Using a bit of starchy water to help with adhesion is a great tip which makes a huge difference in most all of the pasta dishes i make. It is only after I learned this method that I felt confident in my ability to make a great pasta.

        It is unfortunate that most people are not aware of this (including myself up until a few years ago).

    this looks perfect! Just like the ones I had in Rome! They were all so creamy but I knew they must not have cream in them so I’ve been trying to find just the right recipe and this looks to be it. Thanks! Also, one of the trattorias we ate at added in a bit of pink peppercorns and it added a whole new layer to the dish, worth a try sometime!

    HI – thanks for the recipe! One question: why heat up a serving bowl as opposed to using the pot we boil the water in? It will remain hot, won’t it? Or is there something I’m missing?

    November 2, 2013
    • Hi!! using the pot is also a valid alternative. Just make sure to not overcook spaghetti on the pot. Thanks for stopping by,

      November 4, 2013
  25. I wrote a comment a couple weeks ago saying this dish looked great and decided to make this recipe over the weekend. I fell in love! So delicious. I cannot believe how 3 simple ingredients can make such a rich dish. Thank you again for sharing

    • Hello!! I am glad you gave it a try and it turned out well.! Thank you!!!!!!!!

        Why is there milk in the ingredients but not in the recipe?

        June 27, 2016
  26. I have had Cacio e pepe over all sorts of pasta in Italy and it is one of my favourite pasta dishes. Like you said, it is difficult to make it well. I certainly have to train a bit more before I blog about it. I will certainly follow your precious advice and try this again soon!

    January 19, 2014
    • Hello! As I said at the beginning of my post, it takes time to perfect the dish. You have to try different pasta formats and brands (I personally use pasta di Gragnano’s Spaghetti alla chitarra) before you get it right.I also try to find the best Pecorino Romano I can get. As far as water quantity it all depends on the quality of cheese and pasta. Once you find the pasta and Pecorino Romano type that works best for you, try to be consistent and always use these when you make Cacio e Pepe!

    I tried making this last night with good aged pecorino and found that following your instructions made the pasta much too hot and the first half of the cheese clumped! 😦 My husband said to wait a bit to add the second half and to remove the clumps, so I did and tossed with two forks and it achieved that real good creaminess. I would not heat the bowl next time and I would wait a moment after adding in the hot pasta water to the hot pasta to add the fresh grated cheese to mix. Even with half the cheese it was still delicious and creamy.

    September 11, 2014
  28. The recipe sounds convincing. Thank you, I will definitely try it! Only one remaining question: caccio ricotta or pecorino romano?

    Thanks for this recipe, works well.

    Couple of additions:

    Make sure to use the smallest possible holes on the grater, it allows for faster melting and emulsification.

    Make sure your serving bowls are warm!

    December 17, 2014
  31. I just made this recipe. It was delicious. I used the pot that I’d used to cook the spaghetti so perhaps it was too hot as the cheese did clump. I added the hot pasta water and some of the sauce was creamy but it still had cheese clumps. Think I need more practice!

    I am able to get the sauce somewhat creamy but I also find that I get some big clumps of cheese. How can I avoid this?

    August 23, 2015
    • Hi. It all depends on the quality of cheese you use (Pecorini Romano cheese). If you do not get the creamy consistency, try mixing the cheese with the hot pasta water in a blender (immersion blenders are the best) to get a smooth sauce. Add more water if your sauce is too thick, or add more cheese if it is way too runny, until you get the desired consistency. Hope this help!

    I just discovered this recipe on Pinterest and when I looked at the pic I thought “oh its a cream base but it looks so good” (I normally don’t eat cream base dishes). Lo and behold I open the recipe site – no cream! I just made this and it is fabulously good! So simple, yet so superior to any cream sauce out there (imho). I have a soft spot for pecorino and this showcased the cheese wonderfully! Thank you for posting this recipe!

    • Thank you very much! That is very kind of you

    This is the recipe I use. This is the PROPER recipe. I cannot believe the recipes I see online-Saveur, Bon Appetit, Epicurious, and Mario Batali, for Crissake, all use cream, or butter, or oil. The Romans that I know and love (including members of my family), would blanch at using any other recipe. It’s the same with Fettucine Alfredo. Four ingredients. No cream. Look at the crap we get in restaurants. Good work.

        Hi! This is one of the only recipes on the internet with a picture that looks right (and every other one leads back to you!), but I cannot seem to get it quite right.. do you know how much water to cheese you use (cheese/water ratio) for the sauce? Also, you call for “pecorino Romano (the more aged the better)” – what age do you typically use? I’ve read that the minimum for grating on pasta should be 8 months, I think the only one I can find near me is 5 months 😥

        February 11, 2016
      • Hello! thanks for reading and visiting my blog. I understand if you cannot get it quite right. it takes time and a lot of practice. The water/ cheese ratio much depends on how creamy you want your sauce. If you have difficulties in getting it right, I suggest (I usually do it myself) to combine in a saucepan 1/2 cup of grated Pecorino Romano and 1-2 tablespoons of pasta water, then use an immersion blender to combine the ingredients; add more cheese if the sauce is too runny, or more water if it is too thick. As regards to aging of cheese, I use Brunelli (http://www.brunelli.it/pecorino-romano-dop), which is aged for at least 12 months. Hope this helps. Please do not hesitate to contact me should you need further advice. Kindest regards.

    Extremely disappointing – twice now. Lumpy, elastic, watery and a horrible waste. Just google ‘cacio e pepe without butter’ and you’ll find better recipes and explanations.

    Dear Ambrosia, thank you for this great recipe. Minimalistic and essential in its ingredients and handling, as Italian cooking should be. Distilled to basics thru centuries of practice.
    Last time we were in Rome, we had this great pasta dish at Fortunato all Pantheon. They use a large diameter spaghettone, which is good for collecting the sauce, but heavy. I used Bucatini, which are large section but light. Add as little pasta water as possible to the cheese sauce and salt generously.
    Sergio.

    November 26, 2015
    • Thank you for your kind message! Another great restaurant near the Pantheon is Armando al Pantheon, so make sure you visit it on your next trip to Rome! Kindest regards

    I tried it last week in a restaurant whilst in Rome and I cooked it this evening with special Pecorino cheese bought in Rome. I followed the recipe and it was delicious. Thank you.

    Finally a recipe that works! I’m so happy with this. Tried it out tonight and really got that fine creamy texture. Now I just have to work out the water and cheese balance to for the saltiness.
    Cacio e pepe is one of my favourite pasta dishes. I tried to make it for years at home, but could never really match the original Roman taste. Even though my mom is Italian and a great great cook, she’s from Tuscany and could not help me improve the recipe. Great job.

    Thank you for this delicious recipe. I had only one issue. My noodles tend to form knots. I made the spaguetthi myself like always (fresh homemade). There are a little bit more fragile than normal one and I was afraid to get them smashed or broken. Any advice to get a beautiful finish as you does? Thank you!

    ciao! so happy to see your article! i have been trying to make cacio and pepe for a while with mixed success. My big issue is what kind of pecorino cheese to use. i live on the the
    east coast in the US and have tried pecorino locatelli from the supermarket which was way too salty… i think it is used in the states as a topping rather than as a main ingredient. i tried another (antica i think) which was too mild. pecorino ginepro finally worked best. is there a particular type you use? i suspect that the cheese they import to the states might be different than what is available in Europe.

    August 23, 2016
    • Hello. I imagine it is very hard to find a good Pecorino cheese, but don’t worry. If you find it harda to mix all ingredients and get a creamy sauce using the method I explained in my post, try to mix it all up using an immersion blender. Please let me know if this works out for you. Ciao!

    Hi there! Thanks for posting this great recipe. I’ve made it twice already, and like many others, I’m not able to get a creamy sauce without clumps. I have followed your recipe exactly: I’m using high quality pecorino Romano, am heating the serving bowl, and am not letting the pasta or water get cool. When I add the cheese to the hot pasta, it doesn’t melt; most of it just clumps up like mozzarella. The method you describe to make the sauce separately using an immersion blender doesn’t seem to make sense. Could you clarify?

    October 11, 2016
    • Hello there. Using an immersion blender to mix Pecorino cheese, pasta cooking water and pepper is an alternative method to combine the ingredients that otherwise would be blended direclty into the pasta. When you pour pecorino cheese and water into a bendling cup and use an immersion blender, you get a creamy sauce that you mix it with your pasta. I hope this clarifies your doubts.

    I am use to ask for this dish in any new restaurant that I go just to evaluate their skill:

    Da Enzo in Trastavere has the best cacio e Pepe. They make theirs by mixing ice cold water with pecorino Romano in a metal bowl with the pepper. Then add the pasta to the bowl tossing quickly and adding some pasta water as needed. It comes out beautifully creamy. Totally delightful. They also use Sarawak pepper. I love their recipe.
