This recipe is incredibly easy to prepare, rich and delicious! I only make this once in a while because it's a little high in fat and calories, but well worth it. :) I made this recipe using Provolone cheese with the intention of creating a more upscale tasting alfredo. You can serve this over fettucine, or I like to make this recipe with penne and mix it in with the sauce just before serving. A little piece of trivia for you: Alfredo sauce was invented in Rome in the 1920s by restaurant owner Alfrsdo diLello.
