There are three basic pasta sauces everyone should have in their Italian dinner rotation and those are bolognese, pesto, and of course an alfredo. An authentic Roman alfredo is one of the simplest with just a combination of fresh fettuccine pasta tossed with an unforgiving amount of butter and freshly grated parmesan.

While the rich and creamy Americanized version from most menus isn’t far from the original, over time it has taken on some creative liberties. From adding in seasonings like garlic and basil to thickeners like cauliflower or cream cheese, all of these adaptations, in the end, are irresistible. If you’re looking for a quicker, richer fettuccine sauce to try, here are nine of the best alfredo’s in a jar you can buy.
