Instructions
Let’s dive into the steps to create this flavorful masterpiece:
Preheat Your Oven
Preheat your oven to 350°F. This ensures that your mac and cheese gets perfectly golden on top while staying creamy inside.
Cook the Pasta
Boil the macaroni in salted water until al dente. Be sure to not overcook it—this is your base, and you want it to hold its shape while soaking up all that cheesy goodness.
Sauté the Shrimp and Crab
In a large pan, sauté your shrimp with Cajun seasoning until they’re just pink and cooked through. Gently fold in the crab to warm it up, taking care not to break it up too much.
Make the Cheese Sauce
In a separate pan, melt butter and make a roux by stirring in flour. Slowly add milk while whisking constantly until the sauce thickens. Then stir in your shredded cheese until it melts into a silky, creamy sauce.
Combine the Ingredients
Toss the cooked pasta, seafood, and cheese sauce together until everything is well-coated and deliciously creamy. Pour the mixture into a greased baking dish, spreading it out evenly.
Bake to Perfection
Pop it in the oven for about 20 minutes or until the top is golden and bubbly. You want that crispy, cheesy top to form, while the inside stays rich and creamy.
Finishing Touches
Once it’s out of the oven, let it cool for a few minutes before serving. The flavors will settle and intensify, making every bite even more flavorful.
Serve and Enjoy
Dish up this creamy, cheesy goodness and savor every bite. You’ll love how the smoky Cajun spice balances with the sweetness of the shrimp and crab. Enjoy!
How to Serve Cajun Shrimp and Crab Mac and Cheese
This dish is already a complete meal on its own, but here are a few ideas to elevate the experience:
Fresh Salad
Pair it with a crisp, green salad with a light vinaigrette. The freshness will balance the rich, creamy mac and cheese.
Crusty Bread
Serve with warm, crusty garlic bread or a simple baguette to soak up every bit of the cheesy sauce.
Roasted Vegetables
Roasted carrots, zucchini, or asparagus would be excellent side dishes that add both color and nutrients to your meal.
As a Standalone
Sometimes, all you need is the mac and cheese itself. Garnish with some fresh parsley or cilantro to add a pop of color and freshness.

Instructions
For the Cajun Shrimp:
Heat a large skillet over medium heat. In a medium bowl, toss the shrimp with olive oil, Cajun seasoning, salt, and black pepper until coated.
Once the skillet is hot, add the shrimp and cook, stirring constantly, until they turn pink, about 4-6 minutes. Set aside.
For the Pasta:
Preheat oven to 350°F (177°C) and lightly butter a 9×13-inch baking dish.
Bring a large pot of salted water to a boil and cook the macaroni until al dente (follow package directions). Drain well and transfer to a large bowl. Mix in the Cajun shrimp, crab chunks, and basil. Set aside.
For the Cheese/Milk Mixture:
In a large bowl, whisk together whole milk and evaporated milk. Add paprika, cayenne, salt, and pepper. Taste and adjust seasoning as needed.
Add the beaten eggs and combine.
Set aside 1 cup sharp cheddar, ½ cup colby & Monterey Jack, and ½ cup Parmesan cheese. Add the remaining cheese to the milk mixture and stir to combine.
Assembly of the Mac and Cheese:
Pour the cheese mixture into the macaroni and stir to combine.
Transfer to the prepared baking dish and top with the reserved cheeses. Sprinkle with more basil, paprika, salt, pepper, and Cajun seasoning, if desired.
Bake for 45-55 minutes until the top is golden. Cover with foil around the 35-40 minute mark to prevent the cheese from touching the foil.
Remove from the oven and let sit for 25-30 minutes before serving.
