Ingredients

- 2 pounds shrimp, peeled and deveined
- 2 tablespoons olive oil
- 1 to 2 tablespoons Cajun seasoning
- Pinch of salt
- Pinch of freshly ground black pepper
- 3 cups uncooked elbow macaroni
- 2 pounds cooked fresh crab legs or 2 ½ cups diced imitation crab meat
- ¼ cup fresh or dried basil, plus more for topping
- 1 cup whole milk
- 2 to 2 ⅔ cups evaporated milk
- ½ to 1 teaspoon paprika, or to taste
- ¼ to ½ teaspoon cayenne pepper, or to taste
- ½ teaspoon salt, or to taste
- ½ teaspoon freshly ground black pepper, or to taste
- 2 large eggs, beaten
- 4 cups sharp cheddar cheese, grated
- 2 cups mild cheddar cheese, grated
- 2 cups Colby and Monterey Jack cheese blend, grated
- ½ cup Parmesan cheese, grated
- Cajun seasoning for topping
Step-by-Step Directions
- Start by heating a large skillet over medium heat. In a medium bowl, combine shrimp, olive oil, Cajun seasoning, salt, and black pepper. Toss well to ensure the shrimp are evenly coated in the seasonings.
- Once the skillet is hot, add the seasoned shrimp and cook, stirring constantly until they turn pink and opaque, which should take about 4 to 6 minutes. Once cooked, remove the shrimp from the heat and set aside.
- Preheat your oven to 350°F (177°C). Meanwhile, lightly butter a 9×13-inch baking dish and set it aside for later use.
- In a large pot, bring salted water to a boil over high heat. Add the elbow macaroni and cook until al dente, according to package instructions. Drain the pasta thoroughly and transfer it to a large mixing bowl.
- In the bowl with the drained pasta, add the cooked Cajun shrimp, crab meat, and basil. Gently stir to combine, ensuring the ingredients are evenly mixed.
- In another large bowl, whisk together whole milk and evaporated milk. Stir in paprika, cayenne pepper, salt, and black pepper; taste and adjust the seasoning as desired.
- Whisk in the beaten eggs until fully incorporated. Reserve 1 cup of sharp cheddar, ½ cup of the Colby and Monterey Jack blend, and ½ cup of Parmesan cheese separately. Add the remaining cheese to the milk mixture and stir until thoroughly combined.
- Pour the cheese and milk mixture into the bowl with the pasta and seafood. Stir well to ensure everything is coated in the creamy mixture.
- Transfer this delightful mixture into the prepared baking dish. Evenly top it with the reserved cheeses. For added taste, you can sprinkle more basil, paprika, salt, pepper, and Cajun seasoning on top.
- Bake for 45 to 55 minutes, or until the top is golden and bubbly. Keep an eye on it around the 35 to 40-minute mark; if the top is browning too quickly, cover it loosely with foil.
- Once done, remove it from the oven and allow it to rest for 25 to 30 minutes before serving. This resting period will help the flavors meld beautifully.
