What you will need

This recipe uses 5 simple ingredients that you can find at any grocery store:

  • 12 oz tonnarelli or spaghetti pasta
  • 2 cups finely grated Pecorino Romano cheese
  • 2 tsp coarsely ground black pepper
  • 1.5 tsp salt
  • 1 tbsp olive oil

Step by step instructions

Step 1: Cook Pasta and Toast Pepper

Cook pasta in generously salted boiling water until just shy of al dente. Meanwhile, toast the coarsely ground black pepper in a large dry skillet over medium heat for about 1 minute until fragrant. Reserve at least 1.5 cups of starchy pasta water before draining.

Step 2: Create the Cheese Paste

In a bowl, combine the finely grated Pecorino Romano with a few tablespoons of the hot pasta water and stir vigorously to form a smooth thick paste. This step is critical for achieving a creamy lump-free sauce. The paste should be thick but pourable.

Step 3: Combine and Emulsify

Add the drained pasta and a splash of pasta water to the pan with the toasted pepper over low heat. Remove from heat completely, then add the cheese paste and toss rapidly while adding pasta water a little at a time until a glossy creamy sauce coats every strand. Serve immediately with extra pepper.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • Pecorino Romano → a 50/50 blend of Pecorino and Parmesan for a less pungent and slightly milder flavor
  • tonnarelli pasta → spaghetti or bucatini which both work beautifully in this classic Roman preparation

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Adding the cheese paste while the pan is still on high heat, which scrambles the cheese into clumps instead of forming a silky sauce
  • Not grating the Pecorino finely enough, as coarsely grated cheese will never fully melt into a smooth sauce and will remain grainy
