Cacio e Pepe

Three ingredients. No cream. No butter. Just cheese, pepper, and pasta water doing all the heavy lifting. Cacio e Pepe is Rome’s greatest gift to weeknight cooking, and once you nail the technique, you’ll wonder why you ever reached for a jar of sauce.

Ingredients

  • 1 lb spaghetti or tonnarelli
  • 2 cups finely grated Pecorino Romano (about 6 oz)
  • 2 tablespoons freshly cracked black pepper
  • Kosher salt

Step-by-Step Instructions

Step 1: Boil the Pasta

Bring a large pot of well-salted water to a rolling boil. Cook the spaghetti until about 2 minutes short of the package directions. You want it firm because it finishes cooking in the sauce. Save at least 2 cups of pasta water before draining.

Step 2: Toast the Pepper

While the pasta cooks, add the black pepper to a large, cold skillet. Set it over medium heat and toast for about 1 minute, swirling occasionally. You’ll smell it the second it’s ready. Fresh cracked pepper from a good grinder makes a real difference here.

Step 3: Build the Sauce

Pour about 1 cup of the starchy pasta water into the skillet with the pepper. Let it come to a simmer. That cloudy, starchy water is the secret. It emulsifies with the cheese and creates the creamy sauce without any actual cream.

Step 4: Toss the Pasta

Use tongs to transfer the pasta straight from the pot into the skillet. Toss it constantly over medium-low heat for about a minute, letting it soak up the peppery water. Add splashes of pasta water if it looks dry.

Step 5: Add the Cheese

Pull the skillet off the heat. This is important. If the pan is too hot, the cheese will clump instead of melting into a smooth sauce. Add the Pecorino in three batches, tossing aggressively between each. The pasta should look glossy and coated. Add more pasta water a tablespoon at a time if it gets tight.

Step 6: Serve Immediately

Plate it fast. Cacio e Pepe waits for no one. Top with extra grated Pecorino and a generous crack of pepper.

Serving Suggestions

  • Serve with a simple arugula salad dressed in lemon and olive oil
  • Pair with a crisp white wine like Frascati or Vermentino
  • Crusty bread on the side for mopping up any leftover sauce

Tips

  • Grate the Pecorino on a Microplane for the finest texture. Pre-shredded cheese won’t melt properly.
  • The pasta water starch content matters. Use less water than usual when boiling so it gets extra starchy.
  • Work quickly once the cheese goes in. Hesitation leads to clumps.
  • Do not substitute Parmesan. Pecorino Romano is the whole point.
