Ingredients

8 oz elbow macaroni or cavatappi pasta
2 tbsp butter
1 tbsp olive oil
8 oz shrimp, peeled, deveined, and roughly chopped
8 oz lump crab meat
2 cloves garlic, minced
2 cups shredded sharp cheddar cheese
1 cup shredded mozzarella cheese
½ cup grated Parmesan cheese
2 cups whole milk
½ cup heavy cream
2 tbsp all-purpose flour
1 ½ tbsp Cajun seasoning (adjust to taste)
1 tsp paprika
Salt and black pepper, to taste
½ cup panko breadcrumbs (optional, for topping)
1 tbsp melted butter (optional, for topping)
Chopped parsley, for garnish

Instructions

1. Cook the Pasta

Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente. Drain and set aside.

2. Sauté the Shrimp

In a large skillet, heat olive oil over medium heat. Add the shrimp, season with a little Cajun seasoning, and sauté for 2–3 minutes until just pink and cooked through. Remove and set aside.

3. Make the Cheese Sauce

In the same skillet, melt the butter over medium heat. Stir in the minced garlic and cook for 30 seconds. Whisk in the flour and cook for 1 minute to form a roux. Slowly add the milk and heavy cream, whisking constantly to remove any lumps.

4. Add the Cheese and Seasonings

Stir in the cheddar, mozzarella, and Parmesan cheese, a handful at a time, until melted and smooth. Season with the remaining Cajun seasoning, paprika, salt, and pepper.

5. Combine Everything

Add the cooked pasta, shrimp, and crab meat to the cheese sauce. Stir gently to combine everything evenly.

6. Assemble and Bake

Preheat your oven to 375°F (190°C). Transfer the mac and cheese to a greased baking dish. If using, mix the panko breadcrumbs with melted butter and sprinkle over the top.

Bake for 20–25 minutes, until bubbly and golden on top.

7. Serve

Garnish with chopped parsley and serve hot.

Variations

Spicier: Add diced jalapeños or a pinch of cayenne pepper to the sauce.
