    Jump to Recipe Print Recipe
    Crab Alfredo is a decadent dish featuring creamy alfredo sauce and succulent crab on top of your favorite pasta.

    Are you carving a plate of pasta loaded with creamy sauce and maybe a little bit of crab to put it over the top? This Crab Alfredo is rich and creamy without letting the sauce overpower the sweet, delicate crab. It is a comforting meal that feels special without being complicated.

    Read on to learn how to bring together tender crab meat, a silky Parmesan Alfredo sauce, and perfectly cooked pasta.

    plate of crab alfredo

    This recipe may not be an exact duplicate of the Crab Alfredo that used to be served at Red Lobster, but it is still pretty darn delicious. There are a few rumors on the internet as to why it went away:

    • the crab that was in the recipe was not readily available anymore
    • the crab was not sustainably sourced
    • the new CEO wanted to streamline the menu

    Only the PTBs at the company know for sure why, but I encourage you to give this a try. Let us know in the comments below if it tastes like you remember.

    Ingredients for Copycat Crab Alfredo

    This is an occasional celebration food, not something you really should be having on a regular basis. That's okay, sometimes we all need some comfort food. There are not a lot of healthy ingredients in this recipe:

    • half and half
    • butter
    • cream cheese
    • Parmesan cheese
    • garlic powder
    • crab legs (or crab substitute)
    • linguini, fettucine or other pasta of your choice
    • fresh herbs for garnish (e.g. basil or parsley)
