Traditional Alfredo is a simple white/cream sauce. It is made from butter, heavy cream, and Parmesan cheese. While the original style is fantastic, I like to add garlic and seasonings, to make my Alfredo sauce taste even better.

Thick, creamy….AND completely Keto!


Even though it is keto and considered a low-carb recipe, it is still full on creamy, thick and rich… Plus it’s very easy to make and can be used in so many versatile ways.




  • Use a whisk instead of a rubber spatula when mixing… This helps to avoid separating your sauce.


  • Don’t overheat your sauce. Slowly add your ingredients on low. Melted cheese can “break“ and separate once it gets too hot leaving your cheese clumpy.


  • If you were worried about overheating, you can add your Parmesan with the heat off. This also helps to prevent separating.


  • It’s best to start with room temperature cream, cold heavy cream can separate if it’s added to heat when it’s cold… You can either leave it out to get it to room temperature or you could put it in the microwave for a few seconds this also helps prevent separation.


  • Using real Parmesan cheese is best. Powdered cheese will create a grainy texture and does not melt the way fresh Parmesan does. I do use and enjoy the powdered variety, but I usually use that inside the casserole and not to make my sauce.


  • The Parmesan helps to thicken this sauce up. If it isn’t quite thick enough, allow the sauce to stand for 2 to 3 minutes before serving.
