Cajun Crab Alfredo Recipe

Yesterday was the day that I chose to conquer the mess that was my refrigerator. While cleaning out that mess, I found a couple items that needed to be used before expiration dates thwarted my best intentions. The first item was a cup of heavy cream, and the second item was a tub of crab meat. I had purchased the crab meat to make crab dip, but upon arriving home, found I didn’t have everything to do that and so the crab sat…. until yesterday! My refrigerator leftovers made made an excellent Cajun Crab Alfredo recipe that I had to share with you!

An Easy Weeknight Meal

Regular alfredo sauce is not a difficult recipe itself. Rather, it is just a matter of combining butter, garlic, flour, cream, and chicken stock in just the right manner to produce the creamy coating for the traditional fan-favorite of Fettuccine Alfredo. The only additions for our Cajun Crab Alfredo is, of course, crab and some Cajun Seasoning. These simple additions to an already simple recipe make this tasty meal not only one that is sure to be a fan favorite, but also a quick and easy weeknight meal!

Depending on your tolerance for spice, this recipe can be altered to include more or less of the Cajun seasoning (linked below). I included just 1 1/2 teaspoons of it and you could taste the seasoning, but it didn’t overwhelm. If you want a bit more of a kick, add another 1/2 teaspoon. The spice is a great addition to this rich and delicious meal.
