  • large colander
  • large pot
  • large saucepan
  • Liquid measuring cup
  • measuring cups
  • Measuring spoons
  • Wooden spoon


  • 16 ounce package fettuccine
  • 5 Tablespoons salted butter
  • 2 large garlic cloves minced
  • 2 cups heavy whipping cream
  • ¼ teaspoon ground black or white pepper
  • cup grated Parmesan cheese
  • cup shredded mozzarella cheese



  • Cook the fettuccine as per the package instructions and drain.


  • In a medium saucepan over low heat, melt the butter. Once melted, add garlic and cook and stir constantly until the garlic is fragrant about 30-60 seconds.
  • Add in whipping cream and pepper and bring the mixture to a bubble (NOT a boil). Once bubbling, reduce the heat to simmer and simmer while stirring often until the mixture has thickened. This will take about 5 minutes.
  • Add in the Parmesan and mozzarella cheese and continue to cook and stirring occasionally until the sauce has thickened. This will take about 5-10 minutes.


  • Spoon the alfredo sauce over the drained fettuccine and serve.



It’s important to go low and slow with this recipe because of all of the dairy products. If you cook the alfredo sauce over higher heats, you run the risk of the sauce breaking, separating, and becoming grainy.
