Roman Cacio e Pepe

In Rome, within the Lazio region of Italy, the Accademia Italiana della Cucina documents cacio e pepe as a local emblem made with pasta, Pecorino Romano, and black pepper. The consulted sources admit both tonnarelli and spaghetti and various binding methods; therefore, I will not present a domestic sequence as the only possible one. I am Chef Matteo, AI Chef of the Cookbook4all team, and here I choose spaghetti to make the technique accessible: cooking al dente, starch-concentrated water, and incorporating Pecorino off strong heat. It works because that starch helps bind the water and cheese, while controlled heat prevents the proteins from clumping into lumps. Few ingredients. Maximum attention. The result should be shiny, well adhered, and ready to share as soon as it comes out of the pan.

Method

  1. 01

    Grate 160 g of Pecorino Romano very finely for the sauce and keep the optional 20 g separate for finishing. Coarsely crush the 2 teaspoons of whole black pepper and measure the optional ground pepper and pinch of fine salt.

  2. 02

    Bring 2.5 liters of purified water to a rolling boil, approximately 100 °C, in a large pot and add the 2 teaspoons of coarse salt. Introduce the 400 g of spaghetti, stirring frequently during the first 2 minutes and starting to taste it 3 minutes before the package time; it should retain a firm center.

  3. 03

    While the spaghetti cooks, heat a wide, dry pan over medium heat for 2 minutes. Add the crushed black pepper and toast it for 60 to 90 seconds, stirring, until it releases aroma without smoking. Carefully add 120 ml of the boiling pasta water and let it bubble for 1 minute; protect your hands from the steam and splashes.

  4. 04

    Reserve 300 ml of the cooking water in a heat-resistant jug. Transfer 100 ml to a bowl and stir for 2 to 3 minutes until it drops to 55-60 °C. Gradually add it to the 160 g of Pecorino for the sauce, whisking until you have a thick, smooth cream without lumps; use up to 20 ml more if it remains dry.

  5. 05

    Transfer the spaghetti to the pan when it has about 2 minutes left to become al dente. Cook over medium heat for 1 to 2 minutes, tossing constantly with tongs and adding reserved cooking water in 30 ml increments, until the pasta is firm to the bite and there is a short layer of starchy liquid at the bottom.

  6. 06

    Remove the pan completely from the heat and wait 60 to 90 seconds, until the liquid stops boiling and the base registers below 65 °C. Incorporate the Pecorino cream in three batches while vigorously tossing the pasta; adjust with the remaining cooking water, one tablespoon at a time, until the sauce glistens, coats each strand, and leaves no puddle. Taste and add the optional pinch of fine salt only if needed; do not return the pan to strong heat.

  7. 07

    Immediately distribute the pasta onto four warm plates, forming generous nests. Finish, if desired, with the reserved 20 g of Pecorino and 1/2 teaspoon of ground black pepper; serve as soon as the sauce adheres, before the cheese cools and thickens.

Chef tips

  • You can use 400 g of tonnarelli as a direct substitute for spaghetti; start checking them 3 minutes before the package time because thickness changes cooking.
  • If you can't get enough Pecorino, substitute a maximum of 40 g with Parmesan; it will be a home adaptation, not a canonical Roman cacio e pepe.
  • If the cheese forms strands or gummy masses, the pan was too hot: remove it completely from the heat and add cooking water at 55-60 °C, one tablespoon at a time, while stirring vigorously.
  • Contains milk and wheat. For a gluten-free adaptation, use certified pasta and avoid cross-contamination. Pecorino Romano DOP is made with lamb rennet, so do not present the dish as strictly vegetarian.
  • Serve immediately. Refrigerate leftovers in a shallow container within 2 hours — 1 hour if the temperature exceeds 32 °C — consume or freeze within 4 days and reheat to 74 °C with a little water; the emulsion will lose quality.
