Make a rich and creamy homemade Alfredo sauce from scratch in just 15 minutes. This simple recipe uses five core ingredients and tastes better than jarred versions.

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
  • 1/4 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 1 minute until fragrant. Do not let the garlic brown.
  3. Pour in the heavy cream and bring the mixture to a gentle simmer, stirring occasionally. Reduce the heat to low.
  4. Whisk in the grated Parmesan cheese slowly until the sauce is smooth and fully melted. Continue stirring until the sauce thickens slightly, about 3 to 5 minutes.
  5. Season the sauce with salt and black pepper. Taste and adjust seasoning as needed.
  6. Toss immediately with hot, cooked pasta, or use as a topping for chicken or vegetables.

Notes

  • For a thinner sauce, add a splash of reserved pasta cooking water until you reach your desired consistency.
  • Use high-quality Parmesan cheese for the best flavor in this simple Italian sauce recipe.
  • This sauce is best served immediately after preparation.
