Cacio e pepe translates to cheese and pepper, and that is literally all there is to it. Three ingredients. No butter, no cream, no garlic. Just pasta, Pecorino Romano, and an aggressive amount of freshly cracked black pepper. The magic is entirely in the technique.
This dish demands your full attention for about five minutes, but the reward is extraordinary. When the starchy pasta water, melted cheese, and toasted pepper come together in perfect emulsion, the result is a sauce so creamy and intensely flavored that it seems impossible it came from so little.
Ingredients
- 1 lb tonnarelli or spaghetti
- 2 cups finely grated Pecorino Romano
- 2 tbsp whole black peppercorns, coarsely cracked
- Kosher salt for pasta water
Instructions
- 1
Toast the cracked peppercorns in a large dry skillet over medium heat until fragrant, about 2 minutes. Add 1 ladle of pasta water (from the pot you are about to use) and let it reduce slightly. Remove from heat.
- 2
Cook the pasta in salted boiling water until 2 minutes shy of al dente. Reserve 2 cups pasta water before draining.
- 3
Transfer pasta to the skillet with the pepper. Add 1/2 cup pasta water and toss over medium heat until the pasta finishes cooking and the water reduces, about 2 minutes.
- 4
Remove the skillet from heat. Add Pecorino Romano in three additions, tossing vigorously and adding splashes of pasta water between each addition, until a smooth, creamy sauce forms.
- 5
The sauce should be glossy and coat the pasta without being watery or clumpy. Serve immediately with extra Pecorino.

Substitutions
TonnarelliSpaghetti or bucatini
Spaghetti is the most common substitute; bucatini adds fun textural variety.
Pecorino RomanoA 50/50 mix of Pecorino and Parmigiano
Easier to emulsify but less authentically sharp.
Tips & Storage
Pro Tips
Crack your peppercorns with a mortar and pestle or the bottom of a heavy pan for the best texture — pre-ground pepper is too fine.
The pasta water must be starchy. Consider cooking the pasta in less water than usual to concentrate the starch.
Practice makes perfect. This technique takes a few tries to master, and that is perfectly normal.
Storage
Store leftovers in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze individual portions in freezer-safe containers for up to 3 months. Label with the date and recipe name.
Reheating
Not recommended. The emulsion breaks upon cooling. Make a fresh batch instead.

Frequently Asked Questions
- Why does my cheese clump?
- The pan was too hot or the cheese was added too quickly. Always work off the heat and add cheese gradually while tossing.
- Can I use Parmesan instead?
- You can, but it will not be cacio e pepe. Pecorino Romano is essential for the authentic sharp, salty flavor.
