  • 8 ounces fettuccine noodles
  • 2 tablespoons salted butter
  • 1 cup (238g) heavy cream
  • ½ teaspoon kosher salt
  • teaspoon freshly ground black pepper
  • ½ cup (100g) parmesan cheese, freshly grated, plus more for garnish
  • parsley, for garnish (optional)


  • Cook fettuccine noodles according to package directions.
  • Meanwhile, in a large saucepan, melt butter. Then, add cream, salt, and pepper. Bring to a slow rolling boil.
  • Reduce heat and simmer for 3 to 5 minutes, or until the mixture begins to thicken. (It should be thick enough to coat the back of a spoon.)
  • Remove from heat and stir in ½ cup grated parmesan cheese.
  • Drain pasta, reserving a half cup of pasta water. Transfer the drained pasta to a serving dish.
  • Add alfredo sauce to the dish of cooked noodles. Add pasta water (I used ¼ cup) to reach your desired consistency of the sauce. Toss to combine.
  • Serve immediately. If desired, sprinkle with additional parmesan cheese and parsley.
