Make a rich, creamy homemade Alfredo sauce from scratch in just 15 minutes using simple ingredients. This recipe delivers the best Parmesan cream sauce for your pasta night.

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. Do not let the butter brown.
  2. Pour in the heavy cream and bring the mixture to a gentle simmer. Stir often to prevent scorching.
  3. Reduce the heat to low. Gradually whisk in the grated Parmesan cheese, a little at a time, until the cheese is fully melted and the sauce is smooth.
  4. Continue to cook on low for 2 to 3 minutes, stirring constantly, until the sauce thickens enough to coat the back of a spoon.
  5. Remove the saucepan from the heat. Stir in the salt and pepper.
  6. Toss immediately with your favorite cooked pasta, such as fettuccine, or use as a topping for chicken or vegetables.

Notes

  • For a subtle flavor boost, sauté 1 clove of minced garlic in the butter for 30 seconds before adding the heavy cream.
  • If the sauce becomes too thick after sitting, whisk in a tablespoon of warm milk or reserved pasta water to reach your desired consistency.
  • Always use freshly grated Parmesan cheese for the creamiest texture; pre-shredded cheese contains anti-caking agents that can make the sauce grainy.
