Story
I first made Cajun Shrimp and Crab Mac and Cheese for a family dinner when I wanted something comforting but memorable. Traditional mac and cheese always works, but adding shrimp and crab transformed it into a dish that felt special while still easy to prepare. Cajun seasoning gave it warmth, while the blend of cheeses kept everything smooth and rich. Since then, this Cajun Shrimp and Crab Mac and Cheese has become a repeat favorite, especially when I want a satisfying spicy mac and cheese that still feels balanced. It also fits perfectly into the world of cajun comfort food, where bold flavor meets creamy textures.

1 cup whole milk

2–2⅔ cups evaporated milk

½ teaspoon freshly ground black pepper, or to taste
-
2 large eggs, beaten

-
2 cups Colby Monterey Jack cheese, grated

½ cup Parmesan cheese, grated

Step-by-Step Instructions
Preparing the Ingredients
Start by reading through the notes so you can adjust spice levels to your preference. Bring the shrimp to room temperature if frozen, then pat them dry. Grate all cheeses and keep them separated as instructed. Remove crab meat from the shells if using fresh crab, then cut into small chunks. Preheat the oven to 350°F and butter a 9×13-inch baking dish.
Cooking Instructions
Heat a large skillet over medium heat. Toss shrimp with olive oil, Cajun seasoning, salt, and pepper, then cook until pink and opaque, about 4–6 minutes. Set aside. Cook the macaroni in salted boiling water until al dente, then drain well. Transfer pasta to a large bowl and mix in shrimp, crab meat, and basil. In another bowl, whisk together whole milk, evaporated milk, paprika, cayenne, salt, and pepper. Taste and adjust seasoning, then whisk in the eggs. Reserve some cheese for topping, then stir the remaining cheese into the milk mixture. Combine everything with the pasta, transfer to the baking dish, top with reserved cheese, and bake for 45–55 minutes until golden.
Tips for Perfect Results
Common Mistakes to Avoid
Avoid overcooking the pasta, as it continues to soften while baking. Do not skip tasting the milk mixture before adding eggs, since this step controls the overall seasoning. Also, let the dish rest after baking so it sets properly.
Pro Tips for Better Flavor
Use freshly grated cheese for smoother melting. Add extra basil or a light Cajun seasoning sprinkle after baking for aroma. For a richer texture, use the full amount of evaporated milk listed.
Serving and Storage
How to Serve
Serve this Seafood pasta bake hot with a simple green salad or roasted vegetables. It also pairs well with garlic bread or cornbread for a complete meal.
How to Store Leftovers
Store leftovers in an airtight container in the refrigerator for up to three days. Reheat gently in the oven or microwave with a splash of milk to maintain creaminess.

This Cajun Shrimp and Crab Mac and Cheese combines creamy cheese, tender seafood, and bold seasoning into one unforgettable dish. If you enjoy cheesy dinner recipes with a Southern twist, this one deserves a spot in your rotation.
