Instructions

  1. Bring a large pot of water to a boil over high heat and salt generously.
  2. Add the noodles and cook, stirring occasionally, until al dente, about 5 minutes.
  3. Ladle 1/4 cup of the noodle cooking water into a medium skillet. Whisk in the butter bit by bit over low heat, letting each piece melt completely before adding the next, to make a creamy sauce.
  4. Stir in the parsley and season with salt and pepper.
  5. Drain the noodles, toss with the sauce, and serve immediately. Enjoy!
