  • Large pot
  • Colander
  • Bowl

Instructions

  1. Step 1: Bring a large pot of water to a boil with the salt.

  2. Step 2: Add the pasta and cook for the time stated on the package.

  3. Step 3: Just before draining, scoop out 1 cup of the pasta cooking water.

  4. Step 4: Drain the pasta in a colander and leave it for a minute.

  5. Step 5: Transfer the pasta to a bowl; do not use the pasta-cooking pot because it is too hot.

  6. Step 6: Add the pesto and 1/4 cup of pasta water. Toss to coat the pasta, adding more water as needed until it is silky and saucy rather than dry and sticky.

    Pesto-coated spaghetti lifted and tossed with wooden utensils over a bowl.
  7. Step 7: Taste and add more salt and pepper if desired.

  8. Step 8: Serve immediately, garnished with fresh Parmesan.

Notes

Pesto and pasta options

Homemade pesto is recommended for the best flavor, but store-bought pesto can also be used; start with 1/2 cup or more, as it may take less than homemade pesto. The method also works with basil, rocket, or spinach pesto.

For a generous pesto coating, use 300 g / 10 oz pasta. The recipe notes suggest up to 350 g / 12 oz for a more standard amount of sauce per serving, and caution against using more pasta with one batch of homemade pesto.

Leftovers

Store leftovers in a very airtight container in the refrigerator. Do not reheat; let the pasta come to room temperature before eating.

About this recipe

Starchy pasta water loosens the pesto and helps it cling to the pasta, making a glossy sauce without adding extra oil. Ziti, penne, and spaghetti are all options.
