Make a rich, creamy Alfredo sauce from scratch in under 15 minutes using simple ingredients like butter, heavy cream, and Parmesan cheese.

Ingredients

Scale
  • 4 tablespoons unsalted butter
  • 1 cup heavy cream
  • 1 cup freshly grated Parmesan cheese
  • 1/4 teaspoon salt
  • 1/8 teaspoon black pepper

Instructions

  1. Melt the butter in a medium saucepan over medium heat.
  2. Pour in the heavy cream and bring the mixture to a gentle simmer, stirring occasionally. Do not let it boil rapidly.
  3. Reduce the heat to low.
  4. Gradually whisk in the grated Parmesan cheese, a little at a time, until the cheese is completely melted and the sauce is smooth.
  5. Stir in the salt and pepper.
  6. Continue to cook on low heat for 2 to 3 minutes, stirring constantly, until the sauce thickens slightly.
  7. Remove from heat and serve immediately over hot pasta.

Notes

  • Use freshly grated Parmesan cheese for the best melting consistency and flavor. Pre-shredded cheese often contains anti-caking agents that prevent smooth melting.
  • If you prefer a garlic flavor, sauté 1 clove of minced garlic in the butter for one minute before adding the cream.
  • For a thicker sauce, cook for an extra minute or two, or add a little more Parmesan cheese off the heat.
