Shrimp

The shrimp are coated in Cajun seasoning and cooked in butter. You want to undercook them slightly because they will cook more in the oven. You can use either Cajun seasoning or Creole seasoning. I like to use Tony Chachere’s Creole Seasoning

.

Crab

Crab is very expensive but you want to use a good quality crab meat for best flavor. My first choiced is lump crab. If you want to spend less money, use backfin or claw.

Pasta Shape

I typically like to use large elbow macaroni for mac and cheese but cavatappi and penne also work well for this recipe.

Cajun Shrimp and Crab Mac and Cheese Recipe Tips

  • Add a little crumbled bacon for even more flavor.
  • Shred your own cheese for best flavor instead of buying preshredded cheese.
  • As is, this recipe just has a little heat. To spiced it up more, add 1/4 to 1/2 teaspoon of cayenne pepper to the cheese sauce.
