Pasta Cacio e Pepe from Rome & Lazio.

Cacio e pepe is a traditional pasta recipe from the Eternal city, Rome and the Lazio region in general. Like many popular pasta dishes, its roots 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 the shepherds stayed out with their flocks or moved them to different grazing areas, they would carry a number of dried foods to sustain themselves. Foods such as 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.

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!!

ingredients for pasta 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.

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.

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 its peppery taste. To me it’s pasta au poivre!

What kind of pasta should you use?

There are also different views on which pasta works best. In Rome and Lazio, they often make cacio e pepe with either 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.

In the past, I have used bucatini to make cacio e pepe. For this post, I used fresh lombrichelli which some friends sent me from  Lazio. 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!

Author: Jacqueline Debono
  • 400 g lombrichelli (14oz) or tonnarelli, spaghetti alla chitarra, bucatini or normal 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
  1. Dry fry the roughly ground pepper corns in a small frying pan until they start to release their aroma.
  2. 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.

  3. 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.

  4. Add the grated pecorino continue mixing very well until the cheese starts to become creamy.

  5. If too dry add a little more of the cooking water. If too liquid add more cheese.

  6. Serve on heated plates, topped with more grated pecorino and another generous sprinkling of pepper.
Recipe 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.

    My husband’s grandma (from Rome) is an advocate of the bowl method: she swears by mixing the pasta cooking water with pecorino to make a cream. I have also tried your method (love warming up the pepper!) and adding pasta just before it’s al dente to the pan, together with some cooking water and finish it in the pan (facendola “risottare”). I am still unsure as to which is the method I prefer, but I think it’s so interesting that a simple 2-ingredient recipe could have such variation in the preparation techniques!

    What a simple, yet great idea to saute the peppercorns to release flavor. I was also fascinated to see how the pasta cooking water was important in the recipe. And the addition of the pecorino – yum.

    What a delightful look at a simple, and deservedly classic pasta dish! I love that you dove into the variations while still focusing squarely on the roots of the recipe. I feel like this recipe doesn’t get enough credit (despite being rather on-trend in 2016, as you say!) – not only does it feature pecorino Romano so nicely, but it helps us to remember that black pepper is a truly special ingredient that deserves to star in more recipes!
