  • 1 pound Fettuccine noodles cooked al dente (according to package instructions)
  • 12 tablespoons butter
  • 2 cups heavy cream
  • 1 1/2 cups Parmesan cheese freshly grated
  • Optional: 1 tablespoon garlic minced


  • Melt butter in a medium saucepan, but do not bring it to boil. This will cause it to separate.
  • Slowly add the cream. whisk together for about a minute to fully combine the cream and butter. Add the garlic, if you're using it.
  • Bring to a simmer, stirring often, and allow to simmer for just one minute. The sauce will be just slightly thicker.
  • Remove sauce from heat and add grated Parmesan and hot cooked noodles. Stir together until the sauce is creamy and the noodles are covered. Garnish with parsley, if desired.
