Why Youโll Love This Recipe
- Simple yet luxurious: Made with basic ingredients, this dish is proof that less is more when it comes to flavor.
- Quick and easy: With just one large pot of salted water and a large skillet, youโll have dinner ready in under 30 minutes.
- Restaurant-quality results: The creamy sauce clings perfectly to the thick pasta, creating a dish that feels indulgent but is so easy to make.
Ingredients

- Bucatini pasta: This thick spaghetti with a hollow center traps the cheese sauce beautifully. Look for bronze-cut varieties for a better texture.
- Pecorino Romano cheese: A sheepโs milk cheese thatโs salty and sharp, this is the traditional cheese for cacio e pepe. Always grate it yourself using the smallest hole on a grater for the best results.
- Freshly ground black pepper: Use whole black peppercorns and grind them fresh with a pepper mill for maximum flavor.
- Kosher salt: Adds the right balance of seasoning to the large pot of water for cooking the pasta.
- Reserved pasta cooking water: This extra starchy pasta water is the secret to creating the silky sauce that brings everything together.
Ingredient Substitutions
- Parmesan cheese: While not traditional, it can be used in place of Pecorino Romano for a milder flavor.
- Fettuccine or spaghetti: If you canโt find bucatini, these pasta shapes work well as substitutes.
- Pink peppercorns: Add a delicate floral note instead of traditional black peppercorns.
- Gluten-free pasta: Swap in your favorite gluten-free variety for a similar creamy sauce experience.
Ingredient Additions
- Lemon zest: Add brightness and a subtle tang to the cheesy sauce.
- Toasted breadcrumbs: Sprinkle on top for a bit of crunch and extra flavor.
- Olive oil: Drizzle a little high-quality extra virgin olive oil over the dish before serving for richness.
- Chili flakes: For a subtle kick, sprinkle a pinch on top of the finished pasta.
Step by Step Instructions

Cook the Pasta:
Bring a large pot of water to a boil. Add kosher salt to taste, then add 12 oz of bucatini pasta. Cook until just shy of al dente. Reserve at least 1 ยฝ cups (360 ml) of pasta water using a ladle before draining the pasta.

Toast the Pepper:
In a large skillet or wide saucepan, add 2 tsp of freshly ground black pepper and toast over medium heat until aromatic, about 1โ2 minutes.

Create the Sauce Base:
Add about ยพ cup (180 ml) of the reserved pasta water to the pan with the toasted black pepper. Simmer for 1 minute to combine.

Incorporate the Cheese:
Remove the pan from heat. Gradually whisk in 1 ยฝ cups (150 g) of finely grated Pecorino Romano, adding it in small batches. Stir continuously to create a smooth, creamy sauce. Adjust with additional reserved pasta water if needed for a silky consistency.

Combine Pasta and Sauce:
Add the drained pasta to the pan with the sauce. Use tongs to toss the 12 oz of pasta with the sauce until evenly coated. Return to low heat for 1โ2 minutes, stirring constantly to allow the sauce to cling to the pasta.
Serve:
Plate immediately, garnishing with extra Pecorino cheese (about 1โ2 tbsp) and a sprinkle of freshly ground black pepper. Enjoy!
Expert Tips
- Grate your own cheese: Avoid pre-grated cheese, as it doesnโt melt smoothly and can ruin the cacio e pepe sauce.
- Toast the pepper first: Heating the pepper releases its oils, enhancing the overall flavor of the dish.
- Use the right water-to-pasta ratio: Less water in the large pot creates extra starchy pasta water, essential for the silky sauce.
- Donโt overheat the cheese: Stir the cheese off the heat to prevent clumping and ensure a smooth sauce.

Classic Roman Pastas
The Four Roman Pastas are the cornerstone of traditional Roman cuisine, showcasing simple ingredients and bold flavors.
- Cacio e Pepe: Translating to “cheese and pepper,” this minimalist pasta stars Pecorino Romano cheese and freshly cracked black pepper, creating a creamy, peppery sauce that clings beautifully to bucatini or tonnarelli.
- Carbonara: A rich and indulgent dish made with guanciale (cured pork jowl), egg yolks, Pecorino Romano, and black pepper, stirred together with hot pasta to create a luscious, velvety sauce.
- Amatriciana: A vibrant tomato-based pasta that combines guanciale, Pecorino Romano, and a touch of chili, often served with bucatini for its hearty texture.
- Gricia: Sometimes called the “white Amatriciana,” Gricia skips the tomatoes and focuses on the savory depth of guanciale, Pecorino Romano, and black pepper.
Each dish highlights the Roman love of bold flavors and the magic of combining simple ingredients to create timeless classics.
Serving Suggestions
- Wine pairing: Serve with a crisp white wine like Pinot Grigio or a lightly chilled Pecorino (the wine, not the cheese!).
- Elevated presentation: Plate in warm bowls and garnish with freshly cracked pepper and a drizzle of olive oil.
- Side dish: Pair this authentic cacio e pepe pasta recipe with a simple arugula salad dressed with lemon and extra virgin olive oil for a refreshing contrast.
- Charcuterie board companion: Serve alongside Italian meats and cheeses for a crowd-pleasing dinner party option.
Storage Instructions
- Store leftovers in an airtight container in the refrigerator for up to 3 days.
- Reheat gently in a skillet over medium heat, adding a splash of hot water to revive the cheesy sauce.
- Avoid freezing, as the cheese paste can lose its creamy texture.
