Crab Linguini Alfredo Tips

This is probably one of the easiest meals I have made lately. You shouldn’t have any problems. But here are a few tips that will help you out.

Best Type of Crab to Use

Fresh crab meat makes the perfect addition to my alfredo sauce. I always recommend using the freshest ingredients because they have the best taste. You can use snow crab legs, and you don’t have to buy the expensive Alaska King Crab legs.

But you can also use canned crab meat too. If you are going to use canned crab meat, I suggest using lump and backfin meat. The claw meat comes out super shredded and in tinier pieces which can get lost in the sauce and the noodles.

You can also choose to use imitation crab meat.

Is imitation crab meat already cooked? Yes, imitation crab meat is normally pre-cooked. But always check the packaging just in case.

How do you cook packaged crab meat?

Cooking packaged crab meat is super easy. Heat up some butter in a pan and saute the meat for about 5 minutes. It will be ready to add to your sauce and noodles.

How to reheat alfredo sauce

While this dish is a very easy and quick to prepare, I will say you should only make the amount of the Red Lobster Crab Alfredo that you will need to eat in one sitting.

Typically Alfredo sauce and pasta do not reheat well after they have been combined. If you need to save some for later, I would divide up the sauce and the pasta. Often the pasta will soak up the sauce once it is stored. I’m not too fond of the result of reheated pasta.

  • 1 pint half and half
  • 4 ounces unsalted butter
  • 2 tablespoons cream cheese
  • 3/4 cup Parmesan cheese shredded
  • 1 teaspoon garlic powder
  • 8 ounces crab lump meat
  • 16 ounces linguini pasta cook according to package directions


Alfredo sauce preparation

  • In a saucepan, melt butter.
  • When butter is melted, add the cream cheese. When the cream cheese is softened, add half and half, and the Parmesan cheese.
  • Add garlic powder and stir well. Simmer for 15-20 minutes on low. You may wish to season with a little salt and pepper. 

Crab Leg preparation

  • Boil crab legs by filling a large stockpot half full of cold water. Add a tablespoon of salt to the water. Turn the temperature up to high, when the water comes to a boil, add the crab legs.
  • Once the crab legs are added reduce the temperature to medium, and simmer for six minutes. Remove the crab legs from the water. Use a cracker to remove the meat from the crab legs.

Pasta directions

  • Cook the pasta according to the package directions. Drain pasta.


  • Place pasta in a large bowl, pour over alfredo sauce. Stir well. Add crab meat to the pasta after it has been mixed. Gently fold in the crab meat. Plate the pasta and crab met immediately.


Normally, cream cheese isn’t used, but it does help thicken the sauce up without much difference to the taste. You can omit it–just be prepared to stay with the sauce a little longer to thicken it. Boil crab legs as you normally would in boiling water. Crack open legs, dab meat lightly with paper towel to remove excess water, and place the meats on top of the alfredo sauce and pasta.

    My husband’s favorite red lobster dish, made at home, as the last time we had it in the restaurant it fell flat. He was super happy with the turn out. I used snow crab legs, added a bit more garlic powder, and taste tested for salt. The recipe is spot on, thank you so much for this share!
