Cacio e Pepe

Name: Cacio e Pepe
Prep time: 10 min
Cook time: 15 min
Total time: 25 min
Yield: 4 servings
Cuisine: Italian
Ingredients: 340 g spaghetti or tonnarelli; 140 g Pecorino Romano, finely grated; 2 tsp whole black peppercorns, coarsely crushed; fine salt (use sparingly for the pasta water); 240 ml starchy pasta water (reserve at least this amount; use as needed)

Cacio e pepe is built from pasta, Pecorino Romano, black pepper, and starchy water. The challenge is temperature control: the cheese must emulsify without clumping.

Instructions

1
Toast the pepper. Warm the crushed pepper in a wide dry skillet over medium heat for 60–90 seconds, then add 120 ml water and lower the heat.
Look for: The pepper smells floral and fragrant but is not smoking.
2
Cook the pasta shy of al dente. Boil the pasta in lightly salted water. Move it to the pepper skillet 2 minutes before the package time, reserving at least 240 ml pasta water.
Look for: The center is still firm enough to need another 2 minutes of cooking.
3
Finish in the pepper water. Toss the pasta over medium-low heat, adding small splashes of pasta water until it is al dente and a thin starchy coating forms.
Look for: The water looks glossy and lightly thickened rather than soupy.
4
Emulsify off the heat. Let the pan cool for 45–60 seconds. Add the Pecorino in several additions while tossing vigorously, loosening with warm—not boiling—pasta water as needed.
Look for: The cheese forms a smooth coating with no rubbery strings or grainy clumps.

Tips & Variations

→Grate the Pecorino as finely as possible so it disperses quickly.
→If the pan is visibly steaming hard, wait before adding the cheese.
→Serve immediately; the sauce tightens as it cools.

Common mistakes & troubleshooting

The cheese formed clumps.: The pan was probably too hot. Move fully off heat and add the cheese gradually with warm pasta water.
