  • 1/2 pound fettuccine cooked according to package instructions
  • 2 cups heavy cream
  • 2 tablespoons unsalted butter
  • 1 cup Parmesan cheese shredded (2.5 ounces)
  • 1/4 teaspoon kosher salt (add more to taste)
  • fresh black pepper (add more to taste)


  • Bring a large pot of water to a roaring boil. Season with 1 teaspoon kosher salt. Add the fettuccine and cook according to the length of time suggested on the package. Stir immediately after adding it to the water and frequently while it is boiling.
  • In a skillet over medium heat, whisk together the heavy cream and the butter until the butter is melted. Bring it to a simmer, and turn the heat down low. Cook for 15 minutes, stirring occassionally. You should see occasional bubbles.
  • Stir in the Parmesan cheese until it melts. Season with salt and pepper, tasting and adding more as needed. We typically add about 3/4 teaspoon salt and almost 1/4 teaspoon black pepper. The seasoning at the end really pulls together the dish, so be sure to play with this.
  • Toss with fettuccine and enjoy immediately.
