Cacio e Pepe (Single Serving)

serves 1 · 15 minutes · 5 minutes hands on · easy (but technique matters)

Why This Works

The magic is the emulsion: starchy pasta water plus finely grated cheese plus constant tossing makes a creamy sauce with no cream at all. Working off the heat when the cheese goes in is what keeps it silky instead of clumpy.

Ingredients

  • Bucatini (3 oz)
  • Parmesan cheese (1 cup, finely grated)
  • Black pepper (1 tsp, freshly cracked)
  • Salt (for the pasta water)
  • Lemon zest (optional, a small amount for brightness)

Method

  1. Boil the pasta in heavily salted water until 2 minutes before al dente. Reserve 1 cup of pasta water before draining.
  2. Toast the pepper in a small skillet over medium heat until fragrant, about 1 minute.
  3. Add ¼ cup pasta water to the pepper and let it simmer.
  4. Transfer the pasta to the skillet with tongs, bringing some starchy water along.
  5. Off the heat, add the grated cheese gradually while tossing constantly to create an emulsion.
  6. Add pasta water in small splashes while tossing vigorously until the sauce is creamy, not clumpy.
  7. Optional: finish with a touch of lemon zest for brightness.

Notes

  • Work off the heat when adding cheese to keep it from clumping or turning grainy.
  • Extra cheese is key: a full cup (double the usual ½ cup) makes it much creamier.
  • Use a smaller skillet or wide bowl for single portions — easier to build the emulsion.
  • Don't skimp on the pepper — it's half the name of the dish.
  • Serve immediately — the sauce tightens as it cools.
  • Traditional cacio e pepe uses Pecorino Romano, but good Parmesan works great. Grate on a Microplane or the finest grater for the best melt.
