Ingredients Section
Before diving into the ingredients, it’s important to note that this recipe brings together two delicious favorites: Cajun shrimp and creamy mac and cheese, with a touch of sweetness from crab. Perfect for a flavorful, indulgent meal, this combination is sure to satisfy. Now, let’s look at the ingredients for each part:
Cajun Shrimp:
- 2 pounds of shrimp, peeled and deveined
Fresh shrimp gives the best flavor and texture. If you’re using frozen shrimp, thaw them completely before cooking. - 2 tablespoons of olive oil
Helps the Cajun seasoning stick and adds a rich flavor during cooking. - 1-2 tablespoons Cajun seasoning
Adjust this depending on your spice tolerance. - A pinch of salt and freshly ground black pepper
Enhances the shrimp’s natural flavor.
Mac and Cheese:
- 3 cups elbow macaroni, uncooked
This classic pasta holds onto the creamy sauce perfectly. - 2 pounds of fresh crab legs OR 2½ cups imitation crab meat
Fresh crab adds a sweet brininess, but imitation works if you’re on a budget. - ¼ cup fresh or dried basil (plus extra for topping)
Adds a fresh, herbaceous touch. - 1 cup whole milk
Combines with evaporated milk to create the creamiest cheese base. - 2-2⅔ cups evaporated milk
Richer than regular milk, this boosts creaminess significantly. - ½ to 1 teaspoon paprika

Adjust for your preferred spice level. - ½ teaspoon salt and freshly ground black pepper
Balances all the other flavors. - 2 large eggs, beaten
Adds structure to the dish when baked. - 4 cups sharp cheddar cheese, grated
The base of an ultra-cheesy flavor. - 2 cups mild cheddar cheese, grated
A milder cheese for balance. - 2 cups Colby and Monterey Jack cheese, grated
Melts beautifully into the sauce. - ½ cup Parmesan cheese, grated

How to Make Cajun Shrimp and Crab Mac and Cheese
This Cajun Shrimp and Crab Mac and Cheese combines bold flavors with creamy comfort. It’s the perfect dish for seafood lovers, blending spicy Cajun shrimp, sweet crab, and indulgent cheese sauce. Let’s get started:
Cook the Cajun Shrimp
Heat a large skillet over medium heat. Toss shrimp with olive oil, Cajun seasoning, salt, and pepper. Once the skillet is hot, sauté the shrimp for about 4-6 minutes or until pink and cooked through. Remove from the skillet and set aside.
Prepare the Macaroni
Bring a pot of salted water to a boil and add the elbow macaroni. Cook until al dente, as per the package instructions. Drain the pasta well and transfer it to a large mixing bowl, then mix in the shrimp, crab, and basil.
Create the Cheese Sauce
Whisk together whole milk, evaporated milk, paprika, cayenne, salt, and pepper in a mixing bowl. Adjust seasoning to taste before adding beaten eggs. Gradually add in the grated cheeses (save some for topping), stirring until the mixture is smooth and well combined.
Assemble the Dish
Pour the cheese sauce into the pasta mixture and stir to coat evenly. Transfer everything to a buttered 9×13-inch baking dish, spreading it evenly. Top with the reserved cheeses, a sprinkle of Cajun seasoning, and extra basil for garnish.
Bake
Preheat the oven to 350°F (177°C). Cover the dish with foil (to avoid over-browning). Bake for 45-55 minutes, uncovering in the last 15 minutes for a golden crust. Allow the mac and cheese to set for 20-30 minutes before serving.
Additional Tips for Making this Recipe Better
Here’s what worked for me while perfecting this recipe:
- Pre-grate your cheeses for better melting results. Pre-shredded cheeses often have coatings that prevent smooth melting.
- Taste the milk and spice mixture before adding eggs. This lets you tweak the seasoning.
- Add breadcrumbs if you like a crunchy topping. Mix them with melted butter and sprinkle on top before baking.
- Use a baking tray under your dish to catch any spillovers during baking.
How to Serve Cajun Shrimp and Crab Mac and Cheese
To make this dish even more special, serve it with sides or garnishes. A light, crisp salad with vinaigrette can balance its richness. Garnish with parsley or paprika for extra color and flavor. Alternatively, pair it with herb and garlic mashed potatoes for a comforting combo.
