Step 1

Read the notes before beginning the recipe.

Step 2

Heat a large skillet over medium heat. In a medium bowl, add shrimp, olive oil, cajun seasoning, and a pinch of salt and pepper and toss to combine and coat the shrimp.

Step 3

Once skillet is hot, add shrimp and cook, stirring constantly until shrimp is pink, 4-6 minutes. Set aside.

Step 4

Preheat oven to 350F (177C). Lightly butter a 9x13-inch baking dish and set aside.

Step 5

Bring a large pot of salted water to a boil over high heat. Add macaroni and cook until al dente (look at package directions to see how long it takes). Do not overcook.

Step 6

Drain well and transfer cooked pasta to a large bowl. Mix in Cajun shrimp, crab chunks and basil. Set aside.

Step 7

In a large bowl, add milk and evaporated milk and whisk to combine. Add paprika, cayenne, salt and pepper and whisk to combine. Taste the milk and adjust the seasonings to your liking. Once you're satisfied with the taste, add the eggs and beat until mixture is combined.

Step 8

Set aside 1 cup sharp cheddar cheese, 1/2 cup of colby & monterey, and 1/2 cup of Parmesan. Add the remaining cheese to the milk mixture and stir to combine.

Step 9

Pour cheese mixture into macaroni and stir to combine. Pour mixture into prepared baking dish. Top with reserved cheeses. Sprinkle more basil, paprika, salt, pepper and Cajun seasoning on top (optional).

Step 10

Bake for 45-55 minutes or until top is golden. Cover the top with foil around the 35-40 minute mark, making sure it doesn't touch the cheese. Remove from oven and let it sit for about 25-30 minutes to set before serving.
