In this article, we’ll explore various methods for thickening Alfredo sauce, including natural thickening agents and common thickeners used in cooking. We’ll also provide tips for ensuring your Alfredo sauce turns out perfectly every time.

Common Thickeners Used in Alfredo Sauce

  • Flour and Roux: Flour or a roux (a mixture of flour and fat) can be used to thicken Alfredo sauce. The flour is cooked in butter or oil to create a roux, which is then whisked into the sauce to thicken it.
  • Cornstarch: Cornstarch can be used as a gluten-free alternative to thicken Alfredo sauce. It should be mixed with a small amount of cold liquid before being added to the sauce to prevent clumping.
  • Egg Yolks: Egg yolks can be used to thicken Alfredo sauce and add richness. The yolks should be tempered by gradually adding hot sauce to them before being stirred into the main sauce.

Tips for Thickening Alfredo Sauce

  • Use High-Quality Ingredients: Using high-quality butter, cream, and Parmesan cheese can lead to a thicker and creamier sauce.
  • Avoid Overcooking: Overcooking the sauce can cause it to become too thick or curdle.


In conclusion, thickening Alfredo sauce can be achieved through natural processes or by using common thickeners like flour, cornstarch, or egg yolks. By following these tips and techniques, you can ensure that your Alfredo sauce is thick, creamy, and perfect for pairing with your favorite pasta dishes.
