Cacio e Pepe pasta
Cacio e pepe is one of Rome’s greatest gifts to the world. Cheese, pepper, pasta, and the technique that holds it all together, plus a little bit of trust! After making this dish for years, and eating it in Rome more times than I can count, I have now refined the method and it is the best yet.
On this page you will find two versions. The original recipe below is the classic method – it works beautifully and thousands of people have made it successfully. The 2026 version uses less water and no salt in the pasta pot, which creates a starchier cooking liquid that makes the sauce smoother, more stable and less likely to clump. Both are authentic and delicious. The difference is in the technique and I will explain exactly what changed and why.
The number one mistake people make with cacio e pepe is adding the cheese too fast over too much heat. The sauce clumps, and the pasta looks wrong, and the whole dish falls apart. These cacio e pepe recipes avoid that – whatever version you choose to make.Choose your method below, watch the video, and follow the steps.

What Has Changed in 2026 and Why It Matters
After years of making this dish and watching how the sauce behaves, I have refined the technique. The biggest change is the pasta water.
In the original method, I cook the pasta in a large pot of salted water. It works. In the 2026 version, I use less water and no salt. Less water means the starch from the pasta has nowhere to dilute. The cooking liquid becomes more concentrated, and when you use that starchy water to build the sauce, it binds the pecorino more smoothly and reduces the risk of clumping significantly.
This is even backed by science! Research published in 2025 specifically on the physics of cacio e pepe confirmed that a higher starch concentration in the cooking liquid produces a more stable sauce with better emulsification. This is why professional pasta makers in Rome have always used less water than home cooks expect.
The second change is the order of operations with the pecorino mixture. In the 2026 version, the cheese paste goes into the pan before it goes on top of the pot. This gives more control over the temperature and timing, which is where most people lose the sauce.Both methods are on this page. Start with whichever feels right for your experience level.
And while Carbonara and Amatriciana may get most of the attention outside Italy, many Romans will tell you that mastering Cacio e Pepe is the true test of your pasta-making skills. With only a handful of ingredients, there is nowhere to hide. Every movement, every splash of pasta water, and every degree of heat matters.
Vincenzo’s Plate Tips for Making Cacio e Pepe Recipe
Pecorino Romano Cheese
Cacio e pepe should only be made with pecorino romano cheese. The most traditional pasta makers would look at you like you’re crazy if you used anything else. Pecorino romano has a distinct and complex flavor that only it can bring to this pasta dish, plus it makes such a creamy sauce.
When using pecorino romano for this recipe, remember to grate it as finely as possible and follow the cheese-to-pasta ratio. For example, if you wanted to make this dish for two people, you would use 6 ounces (150g) of pecorino romano with 8 ounces (250g) of pasta.
Why Make Cacio e Pepe with Fresh Pasta
Fresh, homemade pasta is the best pasta for cacio e pepe. You can use pasta made with eggs and flour, water and flour, or semolina flour and eggs. Fresh pasta is perfect for this dish because it soaks up all the creaminess of the cheese and brings a thick and chewy texture to the final plate.
Store-bought also works well if you don’t want to make the pasta yourself. Just make sure you get a long, thick pasta that will absorb the sauce – and not a thin spaghettini!
Save Your Pasta Water
While the three ingredients we need are pasta, cheese, and pepper, there is a fourth secret ingredient: pasta water. We use the starchy water to help thicken our cheese sauce. When your pasta is done cooking, don’t strain through a colander into the sink! We are going to need that water throughout the cooking process.
Be Generous with Black Pepper
There isn’t a measurement on how much black pepper to use in this recipe, but more is definitely better, it just depends on individual tastes. We want to add some spice to pair with the silky and salty pecorino romano. So, when adding fresh cracked pepper to the saucepan, don’t think you’re overdoing it. Cover the saucepan’s cooking surface with ground pepper before toasting it to bring out its incredible flavor. And don’t forget to add a little bit to your grated pecorino romano too.
Don’t Add Too Much Water to the Pecorino Cheese
When we start making our cheese sauce, only add a tiny bit of pasta water to the cheese at first and then stir. If you add an entire cup, the sauce will become too watery, and you won’t get that silky, creamy texture we want. Add small amounts of water gradually, stir, and repeat. Continue this process until you have a thick cream. It won’t take too much water to get here, and we will add more pasta water to help thicken the sauce during cooking so don’t tip it out just yet!
Why the 2026 Method Uses No Salt and Less Water
In the 2026 version of this recipe, the pasta cooks in less water than usual with no salt added. For cacio e pepe specifically, the salt is unnecessary – the Pecorino Romano provides all the seasoning the dish needs. More importantly, using less water concentrates the starch in the cooking liquid, which is what makes the sauce bind smoothly to the pasta without clumping.
OPTIONAL: If you prefer the original method, cook the pasta in a large pot of salted water as normal. The result is still delicious – the sauce is just slightly less stable when you are working to combine it.
Tagliolini Works Beautifully Too
Spaghettoni is the recommended pasta for this recipe – the thickness absorbs the sauce beautifully and gives a deeply satisfying bite. If you want a lighter, more delicate result, tagliolini is an excellent alternative. It is thinner, slightly more refined, and works especially well when the sauce is at its smoothest. The method is identical – just watch the cooking time whichever pasta shape you choose.
The Moment Most People Lose the Sauce
Cacio e pepe fails at the moment the cheese meets the heat. If the pan is too hot when you add the pecorino mixture, the proteins seize and you end up with clumps instead of a cream. Remove the pan from the heat completely before adding the cheese paste (you can even count to ten). The residual heat in the pan is enough to melt the pecorino smoothly without overcooking it. Add the pasta water gradually while tossing, and the sauce will come together. If it tightens up, another small splash of starchy water will loosen it immediately.
How to Serve Cacio e Pepe Pasta
Once your cacio e pepe is finished, plate your pasta and then take a spoon and drizzle some leftover cheese sauce from the pan over top of it. You can garnish with a little more freshly cracked pepper if you’d like.

Ingredients
- 250 grams Pasta, 8.8oz. Spaghettone quadrato or Spaghettoni Pasta
- 125 grams Pecorino Romano Cheese, 4.4oz
- Black pepper, Freshly cracked is best.
- 1 Tbsp. rock salt
- Pasta water, as much as required
Instructions
- Bring a large pot of water to a boil.OPTIONAL (Original Method Only): Add 1 tablespoon of rock salt. For the 2026 method, omit the salt, as the starch-rich pasta water and Pecorino Romano provide all the seasoning needed.Add the spaghettone to the pot and cook according to the instructions below.
- Cook the pasta two minutes less than the recommended cooking time it says on the package.
- Place the saucepan on your hot plate and turn up to a gentle heat. Cover the cooking surface with freshly cracked black pepper. Be generous with the amount and toast for approx two minutes then switch off the heat.
- In a separate small bowl, add some black pepper to the pecorino romano cheese and mix it together.
- Use a pair of tongs to take the pasta out of the pot and place it into the saucepan. It’s important to save the pasta water and make sure the heat is turned back on.
- Using a mug, scoop one cup of pasta water and add it to the saucepan with the pasta and pepper. Add enough water to cover most of the pasta.
- Cook the pasta for two minutes while continuously stirring. Then scoop another mug of pasta water and put a little bit into the pecorino cheese and mix it. Gradually add more water and mix until the cheese becomes a thick paste.
- Place your pot with pasta water uncovered onto the stove. Next, place your saucepan on top of the pot. The steam from the water will help us cook the pasta.
- Add the pecorino cream to the pasta and mix it around. Add a little bit more pasta water to the pan.
- Begin to toss the pasta in the pan. If it does not move and can’t be tossed, add a little bit more pasta water. Toss it a few times over the steam to help melt the cheese.
- Place the pasta on a plate and top it with leftover cheese sauce and some black pepper.

Frequently Asked Questions
What is the best pasta for cacio e pepe?
Spaghettoni – thick spaghetti – is the recommended pasta for this cacio e pepe recipe. The extra thickness means the sauce clings properly while giving a deeply satisfying chew in every bite. Mezze maniche is the traditional Roman choice for a short pasta version – the ridges trap the sauce beautifully. Tagliolini works well as a lighter, more delicate alternative using the exact same method. What you should avoid is thin spaghettini – it cooks too fast and does not give the sauce enough to hold onto.
Why does cacio e pepe clump?
Cacio e pepe clumps when the cheese meets too much heat too fast. The proteins in the Pecorino seize and turn stringy instead of melting into a cream. The fix is to remove the pan from the heat completely before adding the cheese paste, count to ten to let it cool slightly, then add the starchy pasta water gradually while tossing. The starch in the water is what binds the cheese into a smooth sauce. The 2026 method on this page uses less water and no salt in the pasta pot specifically because the higher starch concentration makes the sauce more stable and less prone to clumping.
What is the difference between the original and the 2026 method?
The core technique is the same in both versions – toasted pepper, starchy pasta water, Pecorino Romano, no cream. The key differences in the 2026 method are: the pasta cooks in less water with no salt added, which concentrates the starch and produces a more stable sauce; the quantities are updated to 250g pasta and 125g pecorino; and the order of operations with the cheese paste is refined for better temperature control. Both methods produce an authentic, delicious cacio e pepe. The 2026 method is simply more forgiving for home cooks.
Can I use tagliolini instead of spaghettoni for cacio e pepe?
Yes – tagliolini is an excellent alternative. It is thinner and more delicate than spaghettoni, which gives a lighter result while still holding the sauce well. Use exactly the same method as the main cacio e pepe recipe. The only adjustment needed is the cooking time – tagliolini cooks faster than spaghettoni so watch it carefully and transfer it to the pan a minute earlier than you think.
