Creamy Baked Seafood Macaroni and Cheese Tips, FAQ & printable recipe

Tips for success

To achieve the ultimate creamy texture, always warm the cheese sauce gradually over low heat. Keep the heat at a moderate level while melting the cheese into the sauce; high heat can cause the dairy to split, separating the fat and leaving you with a greasy, watery mixture instead of a smooth, cohesive cheese sauce. Sticking to a gentle heat ensures a velvety finish.

Dry the shrimp thoroughly with paper towels before tossing them with the seafood seasoning. Any excess surface moisture on the shrimp will steam instead of sear, and can release too much water into the casserole while baking, which thins out the cheese sauce.

Additionally, let the casserole rest for a full ten minutes after removing it from the oven to let the starches and proteins settle, ensuring clean, scoopable portions that retain their rich, gooey cheese coating.

Variations

• Spicy Cajun Style: Add a teaspoon of cayenne pepper and diced jalapeños to the cheese sauce for a fiery, spicy kick.
• Garlic Herb Crust: Mix panko breadcrumbs with olive oil and garlic powder, then sprinkle over the cheese before baking.

Storage and make-ahead

Fridge

Store leftovers in an airtight container in the refrigerator for up to 3 days, cooling them within 2 hours of baking.

Freezer

Freezing is not recommended as the dairy sauce may split and the shrimp can become rubbery upon thawing and reheating.

Reheat

Reheat individual portions in the microwave at 50% power, or covered in a 325°F (163°C) oven with a splash of milk until hot.

Allow any leftover seafood macaroni and cheese to cool completely at room temperature for no more than two hours to ensure food safety. Transfer the leftovers into an airtight container and store them in the refrigerator. Because this dish contains seafood and dairy, it should be consumed within two to three days. Reheat gently to prevent the cheese sauce from splitting and the shrimp from becoming rubbery.

You can assemble this casserole up to 24 hours in advance. Prepare the pasta, warm the cheese sauce, and fold in the seasoned shrimp, then assemble the dish in the baking pan.

Cover the dish tightly with plastic wrap and store it in the refrigerator. When ready to bake, remove the plastic wrap, let the dish sit at room temperature for 30 minutes, and bake as directed, adding 5 to 10 minutes to the baking time.

Serving ideas

Serve this rich and decadent seafood casserole as the centerpiece of a memorable dinner. It pairs beautifully with a light, crisp green salad tossed in a simple lemon vinaigrette to cut through the richness of the cheese.

Roasted vegetables, such as asparagus, broccoli, or green beans, also make excellent side dishes, adding a fresh, vibrant contrast to the comforting, savory flavors of the macaroni and shrimp. A slice of crusty bread is perfect for wiping up any extra sauce.

For a festive touch, serve this dish in individual ceramic ramekins instead of a large baking dish. This elegant presentation is perfect for dinner parties or holiday gatherings, giving each guest their own portion with a perfectly browned cheese crust.

Pair the meal with a crisp white wine, such as a Sauvignon Blanc or Pinot Grigio, which complements the seasoned seafood and balances the creamy, cheesy elements of the dish beautifully.

Creamy Baked Seafood Macaroni and Cheese

Prep 20 minCook 25 minRest 10 minTotal 55 minServes 6

Ingredients

• 16 oz elbow macaroni, cooked 2 minutes less than package directions
• 1 lb medium shrimp, peeled, deveined, and tails removed
• 1 tbsp seafood seasoning, divided
• 3 cups creamy cheese sauce, store-bought or made ahead
• 2 cups shredded sharp cheddar cheese, divided
• 1 cup shredded gruyere cheese, divided
• chopped fresh herbs for serving

Instructions

1. Preheat the oven to 375°F (190°C). Cook the elbow macaroni in a large pot of salted boiling water for 2 minutes less than the package instructions for al dente, then drain and set aside. In a medium bowl, toss the raw shrimp with half of the seafood seasoning and place them in the refrigerator to stay cold.
2. In a large saucepan, warm the creamy cheese sauce over medium-low heat, stirring frequently to prevent scorching. Stir in the remaining seafood seasoning until fully incorporated and the sauce is hot and smooth.
3. Reduce the heat to low and stir in 1 1/2 cups of the sharp cheddar cheese and 1/2 cup of the gruyere cheese. Stir constantly until the cheese is completely melted and the sauce is perfectly smooth, then remove the saucepan from the heat.
4. Add the cooked macaroni and the seasoned raw shrimp from the refrigerator to the warm cheese sauce, stirring gently until everything is evenly coated. Transfer the mixture into a greased 9x13-inch baking dish, spreading it into an even layer.
5. Sprinkle the remaining 1/2 cup of sharp cheddar cheese and 1/2 cup of gruyere cheese evenly over the top of the pasta. Bake in the preheated oven for 20 to 25 minutes, until the cheese is bubbling and golden brown, and the shrimp are cooked through, reaching a safe internal temperature of 145°F (63°C).
6. Remove the baking dish from the oven and let the casserole rest for 10 minutes to allow the rich cheese sauce to set. Sprinkle with the chopped fresh herbs just before serving warm.
