I use this recipe every time I make Alfredo sauce. I've tried others with cream cheese or no Parmesan, but they just aren't the same and good old fashioned Alfredo with cream. It's a simple and quick recipe, easy to do while waiting on your pasta or side dishes.
3 Tablespoons butter
8 fluid ozs heavy whipping cream
salt to taste
1/4 cup Parmesan cheese, grated
1/4 cup Romano cheese, grated
1 egg yolk
1. Melt the butter in a pan over medium high heat. Add the whipping cream, stirring constantly. Sprinkle some salt, then add the Parmesan and Romano cheeses stirring until melted. Mix in egg yolk, and simmer over low heat for 3 to 5 minutes. Garnish with additional Parmesan cheese, if desired.
