Classic's note

The whole dish lives or dies on pasta water. That cloudy starch is what turns cheese and pepper into a glossy sauce instead of a stringy clump.

Method

7 steps · tap one to tick it off

Tips

  • Grate the cheese as fine as possible. Use the smallest holes or a rasp. Fine cheese melts straight into the starchy water; coarse shreds clump into strings first.

  • Cook the pasta in less water. A wide pan with less water than usual makes starchier cooking water, which is what holds the cheese in a smooth sauce.

  • Crack the pepper coarsely. Coarse pieces toast without burning in those 40 seconds and give the sauce its bite. Fine pre-ground pepper scorches and turns bitter.

Swaps

  • No Cheese (Parmesan)? Pecorino Romano, the traditional Roman cheese. Saltier and sharper, so salt the water even less.

  • No Pasta (Spaghetti)? Tonnarelli, bucatini or linguine. Thick strands release more starch for the sauce.

Storage

  • Fridge: 3 to 4 days in a sealed container. The sauce sets and turns clumpy as it cools.

  • Freezer: Not worth freezing: the cheese sauce splits and turns grainy once thawed.

  • Reheat: In a skillet over low heat with a splash of water, tossing, until steaming hot (75°C in the center).

Fridge and reheating follow Illinois Extension; freezer times are for quality and follow the University of Nebraska-Lincoln, as on what freezes and what does not.
