Ingredients

Scale
  • 4 tablespoons unsalted butter
  • 2 cloves garlic, minced
  • 1 cup heavy cream
  • 1 cup freshly grated Parmesan cheese, plus more for serving
  • 1/4 teaspoon salt
  • 1/8 teaspoon black pepper

Instructions

  1. Melt the butter in a medium saucepan over medium heat.
  2. Add the minced garlic to the melted butter and cook for about 30 seconds until fragrant. Do not let the garlic brown.
  3. Pour in the heavy cream. Bring the mixture to a gentle simmer, stirring often. Reduce the heat to low.
  4. Remove the saucepan from the heat. This step is important to prevent the cheese from clumping.
  5. Gradually whisk in the grated Parmesan cheese, a little at a time, until the cheese is fully melted and the sauce is smooth.
  6. Stir in the salt and pepper. Taste the sauce and adjust seasoning if needed.
  7. If the sauce is too thick, add a tablespoon of reserved pasta water or milk until you reach your desired consistency.
  8. Toss immediately with cooked fettuccine pasta or serve over your favorite protein or vegetables.

Notes

  • Use freshly grated Parmesan cheese for the creamiest, non-grainy texture. Pre-shredded cheese often contains anti-caking agents that prevent smooth melting.
  • Always remove the sauce from the heat before adding the Parmesan cheese to achieve a velvety Alfredo sauce.
  • This recipe is a great base for chicken Alfredo or shrimp fettuccine.
