Alfredo is a recipe that is so good because of the rich ingredients. It is almost decadent. If you want to make it even better, you can add more cream or cream cheese. This adds even more richness to the sauce. There is a ton of cheese in the sauce, but when you are serving, add freshly grated parmesan cheese on top. Because the cheese isn't melted in, it gives it a different flavor than the cheese in the sauce and makes this even better. You can even add more blackening seasoning or your favorite cajun seasoning. If you are one of those people who can not get enough, add more. You can add the perfect amount to make this delicious dish outstanding.
