Make a rich, creamy homemade Alfredo sauce from scratch in just 15 minutes using simple ingredients. This recipe delivers classic Italian flavor without complication.

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. Stir in the salt and pepper. Taste the sauce and adjust seasoning if needed.
  5. Remove the sauce from the heat immediately once smooth. Toss with your favorite cooked pasta, like fettuccine, or use as a topping.

Notes

  • For a garlic Alfredo sauce variation, sauté 1 clove of minced garlic in the butter for 30 seconds before adding the heavy cream.
  • If the sauce thickens too much upon standing, whisk in a tablespoon of warm milk or reserved pasta water to reach your desired consistency.
  • Use high-quality, freshly grated Parmesan cheese for the best melting and flavor. Pre-shredded cheese often contains anti-caking agents that prevent smooth sauce formation.
