Pasta Cacio e Pepe


Jump to Recipe Print Recipe

Cheese and pepper pasta from Rome.

Pasta cacio e pepe is a traditional recipe from the Eternal city, Rome and the Lazio region in general. This easy to make Roman classic has only 3 main ingredients; Pecorino Romano cheese, black pepper corns and, of course pasta! It can be on the table in about 30 minutes, so perfect for a weeknight meal but special enough to serve to guests!

The origins of cacio e pepe.

Like many popular pasta dishes, the roots of this pasta cacio e pepe can be found in the simple food of the peasant population. In this case, mainly the shepherds of the Agro Romano - a term first used in the 15th century to describe the vast rural area of hills and plains that surrounded Rome. 

Italian food historians say when shepherds stayed out with their flocks or moved them to different grazing areas, they would carry a number of dried foods to sustain themselves. These included dried tomatoes, dried pork cheek, cacio cheese (pecorino Romano), pepper corns and dried homemade pasta. From these ingredients, they produced simple filling meals like cacio e pepe and all'amatriciana.

Apparently, the pepper corns were included because they helped the shepherds to stay warm during the chilly nights outdoors! Pecorino was the cheese of choice. As a sheep’s milk cheese, it was mostly homemade and once dried, pecorino has a long life. Pasta, of course, added bulk to the meal and was easy and cheap to prepare.

Step 1 Gather your ingredients. Pasta, black pepper corns and Pecorino Romano cheese.

What does cacio e pepe mean?

Basically, cacio e pepe means cheese and pepper. In fact 'cacio' is used to mean cheese in a number of Italian regions. For example, caciocavallo means horse cheese. It got its name because the cheese is matured whilst hanging over a horizontal beam like a saddle horse. In Rome, when they say 'cacio' they refer to Pecorino Romano.

New York's trendiest dish 2016!

It’s interesting that many of the ‘dishes’ we see today on smart Italian restaurant menus in Rome, as well as cities like London and New York, started out as simple fare for the poorer, rural Italian population. I recently read that cacio e pepe was declared New York’s trendiest dish 2016 by Time Out Magazine!!

Step 2 Prepare the ingredients. Grate the cheese and crush the pepper corns.

Mastering cacio e pepe.

Despite being very trendy, cacio e pepe is far from pretentious. It is easy to make once you have got the hang of it. Plus, it needs only 2 ingredients, apart from the pasta, Pecorino Romano cheese and black pepper corns!

The only trick is to find the perfect balance between the cheese and the pasta. It's important that the dish doesn’t turn out too dry or the sauce too lumpy or liquid. Once you have got that right, this is a dish you can produce in less than 30 minutes, including the time it takes to boil the water for the pasta.

Step 3 Dry fry the crushed black pepper corns in a frying pan until they release their aroma.

Different ways to make a simple sauce!

Believe it or not, there are different ‘ways’of making this simple dish. In my research, I’ve come across a number of articles, in both Italian and English, on the merits of the different techniques!

Some people just boil the pasta al dente, and then vigourously mix it with grated pecorino, freshly ground pepper corns and some of the pasta cooking water. This is reserved before draining the pasta and gives the dish a creamy consistency. This is what I did, although I cooked the pepper in a dry frying pan to bring out the flavour first.

Step 4 Cook the pasta al dente. I used fresh lombrichelli from Rome. This pasta is a thick spaghetti similar to tonnarelli.

Pasta au poivre!

Others advocate mixing the cheese together with the ground pepper and some of the pasta cooking water in a bowl before adding the pasta to it. Another variation involves adding a little butter or oil to the pasta before mixing in the cheese, cooking water and pepper. In general, cacio e pepe may need a bit of practice to get right. But, once you do, you are bound to fall in love with this pepper pasta. To me it’s pasta au poivre!

Step 5 Add some pasta cooking water to the pan with the pepper. Then add the drained pasta.

What kind of pasta should you use?

There are also different views on which pasta works best in this recipe. In Rome and Lazio, they often make cacio e pepe with either thick long pasta such as bucatini , spaghetti alla chitarra (called tonnarelli in Rome), lombrichelli or even just normal spaghetti (although some Roman chefs think normal spaghetti is a no no!) Others prefer to use short tubes like penne or rigatoni or something in between such as pici, short hand rolled thick spaghetti.

Step 6 Add the grated Pecorino and start to stir the pasta, cheese, pepper and pasta cooking water over a low heat.

In the past, I have used bucatini and tonnarelli to make cacio e pepe. For this post, I used fresh lombrichelli which some friends sent me from  Lazio. It's actually very similar to tonnarelli. Obviously, it’s great to be able to make cacio e pepe with traditional pasta. However, even if you have no other choice but normal spaghetti, don’t despair. It will definitely taste great anyway!

Step 6 Continue stirring until you have a creamy sauce that coats the pasta.

How to stop the cheese from clumping.

Some people have a problem with getting the Pecorino to melt without clumping. This could depend on the quality of the cheese, especially if it's not Italian Pecorino Romano. One way to avoid this is to mix the cheese with some hot pasta cooking water until it melts before adding them both to the pan.

Cacio e pepe pasta is not vegetarian.

Although this recipe traditionally has no meat or seafood in it, cacio e pepe is not vegetarian. This is because Pecorino Romano is made using animal rennet. The same is true for Parmigiano. To make this recipe vegetarian, you will need to use a different hard cheese.

Step 7 Serve your pasta cacio e pepe imediately with some more grated pecorino if required.

Ingredients
  

  • 400 g lombrichelli or tonnarelli (14oz) also made with spaghetti alla chitarra, bucatini or thick spaghetti
  • 200 g Pecorino Romano cheese (7oz) freshly grated
  • Freshly ground black pepper corns about 4 teaspoons Don’t grind too fine.
  • Salt for boiling the pasta

Instructions
 

  • Dry fry the roughly ground pepper corns in a small frying pan until they start to release their aroma.
  • Put a pot of water onto boil for the pasta. Use a bit less water than you would normally. Add salt once it starts to boil and bring to the boil again.
  • Cook the pasta al dente according to the instructions on the packet. Take a ladleful of the pasta cooking water and add to the pepper corns. Then keep aside another cupful of the cooking water, drain the pasta and add it to the pan with the peppercorns. I drain the pasta 'wet' meaning it should still have some water with it. Mix the pasta with the pepper.
  • Add the grated pecorino continue mixing very well until the cheese starts to become creamy.
  • If too dry add a little more of the cooking water. If too liquid add more cheese.
  • Serve on heated plates, topped with more grated pecorino and another generous sprinkling of pepper.

Notes

An alternative way to make the sauce is to put the cheese and most of the pepper in a large, heavy bowl or pan and beat in some of the pasta water very gradually to make first a paste, and then a sauce the consistency of bechamel.
Add the pasta and toss well while adding more water if necessary, until you have a sauce that coats each strand of pasta. Don’t worry if it takes a while to come together – keep mixing and it should happen.
It is also recommended to use less water than usual when cooking the pasta (about half), because this will result in cooking water that is rich in starch and will make it easier to obtain a creamy result.

    Excellent, classic recipe. I’d just use a little less cheese.

    I think this my new go to pasta dish. The tip about adding the pasta water (slowly) and whisking it into the cheese in a bowl to make a creamy cheese sauce and then adding the pasta (using tongs) and toasted peppercorns to the cheese mixture works great...no clumping and I was able to easily control the amount of liquid and the temperature of the pasta. After several meals, I now prefer the cheese mixture to include parmesan. My only question is why this pasta is virtually never on the menu of Italian restaurants.

    Dear Jacqui, Thank you for this recipe which I have made many times, including once on a camping trip near Jasper, Alberta. Nothing like enjoying this dish next to a campfire with a glass of wine. My question is about the music you chose to accompany your cacio e pepe video. Would you be able to share the name of this artist? It’s wonderful. Many thanks.

      Hi James, thanks for your comment. I'm happy to hear you like my cacio e pepe recipe! Love the idea it can be made on a camping trip. The music is by an Italian singer called Stefano Fucili. I download it from a site I use for creating videos as it's copyright free. Here's a link to the singer's YouTube page. The song is called lullaby. https://www.youtube.com/c/StefanoFuciliYT

    One of the few “authentic” recipes that is actually ly correct. All others omit the dry frying the peppercorns then grinding them very important, I’d just add to reserve one cup of the pasta and peppercorns to finish the pasta with the peppercorns and the other cup to make the cheese sauce which is make with piccorino Romano and pasta water only made into a paste and mixed in
    Also the peppercorns after frying dry and ground and put back in the pan and you add pasta, pasta water then the cheese blend (water and cheese)

      Thanks for your comment Giuseppe! I think dry frying the peppercorns really is essentially to get the right flavour and aroma. It's interesting that there are different ways to make this 2 ingredient pasta condiment. The important thing is to find the way that works for you. Next time I make it, I'll try your method of mixing some pasta cooking water with the pecorino before adding it to the pasta.
