Seafood Mac & Cheese Bake

Prep Time: 35 minutes
Cook Time: 25 minutes (plus 10-15 minutes baking)
Total Time: 1 hour 15 minutes
Servings: 8 generous portions
Skill Level: Intermediate
Recipe Intensity: Moderate (Involves making a cheese sauce and cooking seafood, but steps are sequential and manageable)

For the Pasta & Seafood:

For the Cheese Sauce:

6 tbsp unsalted butter
½ cup all-purpose flour
4 cups whole milk, warmed
2 cups heavy cream
1 tbsp Dijon mustard
1 tsp garlic powder
½ tsp smoked paprika
¼ tsp ground nutmeg
4 cups shredded cheese blend (recommended: 2 cups sharp white cheddar, 1 cup Gruyère, 1 cup Fontina)
1 cup freshly grated Parmesan cheese, divided
Salt and white pepper to taste

For the Topping:

Optional Garnish:

Cook the Pasta: Bring a large pot of generously salted water to a boil. Cook pasta according to package directions for al dente (usually 1-2 minutes less than recommended). Drain, rinse briefly with cool water to stop cooking, and return to the pot. Toss with 1 tablespoon of olive oil to prevent sticking. Set aside.
Cook the Shrimp: Pat shrimp dry and season with Old Bay, salt, and pepper. Heat remaining 1 tablespoon olive oil in a large skillet over medium-high heat. Add shrimp in a single layer and cook for 1-2 minutes per side until pink and opaque. Remove to a plate. Once cool enough to handle, chop into bite-sized pieces.
Prepare Seafood Mix: In a medium bowl, gently combine the chopped shrimp, lump crab meat, and chopped lobster meat. Drizzle with lemon juice and toss gently. Set aside. Be careful not to break up the crab lumps too much.

Make the Roux: In a large saucepan or Dutch oven, melt 6 tablespoons butter over medium heat. Once melted and bubbling, whisk in the flour. Cook, whisking constantly, for 2-3 minutes until the mixture turns light golden brown and smells nutty. This cooks out the raw flour taste and is crucial for sauce thickness.
Gradually Add Dairy: Slowly pour in the warmed milk and heavy cream while whisking constantly to prevent lumps. Continue whisking until the mixture is smooth. Add Dijon mustard, garlic powder, smoked paprika, and nutmeg. Bring to a gentle simmer, whisking frequently.
Incorporate Cheese: Reduce heat to low. Gradually add the shredded cheese blend and ½ cup of the Parmesan cheese, one handful at a time, whisking until each addition is completely melted before adding the next. This ensures a smooth, emulsified sauce rather than a grainy one.
Season the Sauce: Season generously with salt and white pepper (which won’t show dark specks in your sauce). Taste and adjust seasoning—the sauce should be well-seasoned as it will coat the pasta and seafood. Remove from heat.

Preheat Oven: Preheat oven to 375°F (190°C). Lightly grease your 9×13 baking dish.
Combine Everything: To the pot with the cooked pasta, pour the cheese sauce and gently stir until every piece is coated. Add the seafood mixture and fold gently to distribute evenly without breaking up the crab lumps.
Transfer to Dish: Pour the mac and cheese mixture into the prepared baking dish, spreading it into an even layer.
Prepare Topping: In a small bowl, combine panko breadcrumbs, ¼ cup Parmesan cheese, melted butter, parsley, and lemon zest. Mix until all crumbs are moistened.
Add Topping: Sprinkle the panko mixture evenly over the entire surface of the mac and cheese.

Bake: Place the baking dish on the middle rack of the preheated oven. Bake for 15-20 minutes, or until the topping is golden brown and the sauce is bubbling around the edges.
Optional Broil: For extra crispy topping, switch the oven to broil for the final 1-2 minutes, watching carefully to prevent burning.
Rest: Remove from oven and let rest for 10 minutes before serving. This allows the sauce to set slightly for cleaner servings.

Note: Nutritional information is an estimate. Using lower-fat dairy or adjusting cheese amounts will alter these values significantly.
