For a delicious and comforting twist on two classic Southern dishes, try Crawfish Mac and Cheese! This rich and creamy dish features succulent crawfish, a blend of creamy cheeses, and a golden, crunchy topping for a creamy, cheesy, and flavorful dish that is sure to please.

Crawfish are native to Louisiana. In the southern U.S., they have crawfish boils like most people have shrimp boils. Crawfish are also a staple in jambalaya, gumbo, and etouffee.

Southern Comfort Food

‘Mud bugs’, as crawfish are called sometimes, take a little work to peel. However, they’re well worth the trouble. These little nuggets are similar in taste and texture to lobster.

Additionally, crawfish pairs perfectly with the smoky bacon, gooey cheese, zesty Cajun seasoning, and pasta. You’re going to love this super-indulgent seafood pasta recipe.

I’m sure outside the South, there aren’t many people that eat crawfish. Maybe, they don’t even know what they are! Crayfish are freshwater crustaceans resembling small lobsters. They’re in season during the spring, but you can buy frozen crawfish all year.

Shrimp, especially Royal Red Shrimp, is a good substitution if you can’t get crawfish for this recipe.

Creamy Crawfish Mac and Cheese

Mac and cheese is classic comfort food. Adding crawfish takes this seafood pasta recipe to an all-time high.

Use fresh or frozen crawfish. I find the peeled crawfish tails in the freezer section of my local grocer.

First, I made a traditional roux using the grease from the bacon. Next, I threw in cajun spices to give it a Southern flavor. I then gave the recipe a flavor punch with Monterrey Jack and sharp cheddar cheese. Finally, I topped it with buttery breadcrumbs for a little crunch and texture.

I highly recommend you grab this flat whisk. It’s the best whisk for making bechamel or any sauce or gravy in a pan.

  1. I tried this and it definitely didn’t come out looking as good as yours!

  2. Northerner here! Just wanted to let ya’ll know we have crawfish up in Michigan. Not just frozen tails, but they’re a native species.

  3. After reading all these reviews I feel blessed because down here in south Louisiana crawfish and shrimp are very plentiful and I never realized how scarce they are in other places. This recipe is pretty close to being authentic Louisiana cuisine except some would replace the bacon with tasso or chopped andouille sausage. One may also prepare this recipe using shrimp.

      1. 5 stars
        This recipe was simple and easy. Substituted half and half with almond milk. I use elbow noodles. Maybe a little too much. I recommend using 1 & 1/2 cup of dry elbow noodles. Used turkey bacon. Came out great. I poured this over a smoked turkey leg. Delicious!

  4. Only buy frozen crawfish from Louisiana. Chinese crawfish are not what you want going in your body!
