Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
12 oz elbow macaroni
2 lb shrimp, peeled and deveined
1 cup lump crab meat, shells removed
2 tbsp olive oil
1 to 2 tbsp Cajun seasoning
3 tbsp unsalted butter
3 tbsp all-purpose flour
3 cups whole milk
1 cup heavy cream
2 cups shredded sharp cheddar cheese
1 cup shredded mozzarella cheese
1/2 cup grated parmesan cheese
1 tsp garlic powder
1/2 tsp smoked paprika
1/2 tsp salt
1/2 tsp black pepper
1/4 tsp cayenne pepper (optional)
1/2 cup shredded cheddar cheese for topping
2 tbsp chopped fresh parsley
Directions
Cook the macaroni according to package instructions in a large pot of salted boiling water until al dente. Drain and set aside.
Place the shrimp in a bowl and toss with olive oil and Cajun seasoning until evenly coated.
Heat a large skillet over medium-high heat. Cook the shrimp for about 2 to 3 minutes per side until pink and cooked through. Remove from the skillet and set aside.
In a large saucepan, melt the butter over medium heat. Add the flour and whisk continuously for about 1 to 2 minutes to create a roux.
Slowly whisk in the milk and heavy cream. Continue whisking until the mixture becomes smooth and begins to thicken.
Add garlic powder, smoked paprika, salt, black pepper, and cayenne pepper. Stir well.
Add the shredded cheddar, mozzarella, and parmesan cheese. Stir until the cheese melts and the sauce becomes smooth and creamy.
Add the cooked macaroni to the cheese sauce and stir until well coated.
Gently fold in the cooked shrimp and crab meat.
Transfer the mixture to a greased 9×13-inch baking dish. Sprinkle the remaining cheddar cheese over the top.
Bake in a preheated oven at 375°F (190°C) for about 20 minutes, or until bubbly and lightly golden on top.
Remove from the oven, sprinkle with chopped parsley, and serve warm.
You can customize this seafood mac and cheese in several ways depending on your taste preferences.
Add sautéed bell peppers and onions to introduce extra flavor and texture. A bit of diced jalapeño can also enhance the Cajun spice.
For an even richer dish, mix in cream cheese with the sauce for extra creaminess.
If you prefer a crunchy topping, combine breadcrumbs with a little melted butter and sprinkle them over the cheese before baking.
You can also substitute part of the shrimp with scallops or lobster for a more luxurious seafood variation.
Storage/Reheating
Store leftover Cajun shrimp and crab mac and cheese in an airtight container in the refrigerator for up to 3 days.
To reheat, place a portion in a microwave-safe dish and heat in 30-second intervals, stirring between each interval until warmed through.
For oven reheating, place the pasta in a baking dish, add a small splash of milk to restore creaminess, cover with foil, and heat at 350°F (175°C) for about 15 minutes.
Freezing is also possible. Allow the dish to cool completely, then store it in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating.
FAQs
Can I use frozen shrimp for this recipe?
Yes. Just make sure the shrimp are fully thawed and patted dry before seasoning and cooking.
What type of crab meat works best?

What cheeses melt best for mac and cheese?
Cheddar, mozzarella, and parmesan are excellent choices because they melt smoothly and create a rich flavor.
