  • Salt – 1 tbsp enhances the flavor during pasta boiling.

For the Sauce

  • Unsalted Butter – 4 tbsp is essential for creating the roux for the cheese sauce.
  • All-purpose Flour – ¼ cup thickens the sauce beautifully.
  • Whole Milk – 4 cups forms the creamy base; remember to warm it before adding.
  • Heavy Cream – 1 cup adds a rich, velvety texture to the sauce.
  • Dijon Mustard – 2 tsp for that hint of tanginess; totally optional for flavor depth.

Step‑by‑Step Instructions for Seafood Mac and Cheese

Step 1: Cook the Pasta
Begin by bringing a large pot of salted water to a rolling boil. Add 1 pound of elbow macaroni and cook it until al dente, about 8–10 minutes. Stir occasionally to prevent sticking. Once cooked, drain the pasta in a colander and set it aside while you prepare the seafood and cheese sauce.

Step 2: Sauté the Seafood
In a large skillet, heat 1 tablespoon of olive oil or butter over medium heat. Add ½ pound of shrimp and ½ pound of scallops, cooking for 2–3 minutes on each side or until they’re just opaque. Carefully fold in ½ pound of lump crab meat, season with salt and pepper, then remove the skillet from the heat and set it aside.

Step 3: Prepare the Cheese Sauce
In a saucepan, melt 4 tablespoons of unsalted butter over medium heat to create a roux. Whisk in ¼ cup of all-purpose flour, stirring constantly for about 1 minute. Gradually pour in 4 cups of warmed whole milk and 1 cup of heavy cream, whisking until the mixture is smooth and begins to thicken, roughly 5 minutes.

Step 4: Incorporate Seasonings and Cheese
Once your cheese sauce has thickened, remove it from heat. Stir in 2 teaspoons of Dijon mustard, 1 teaspoon of Old Bay seasoning, ½ teaspoon of garlic powder, and ½ teaspoon of salt and ¼ teaspoon of black pepper to enhance the flavors. Gradually fold in 2 cups of shredded sharp cheddar cheese, 1 cup of shredded Gruyère cheese, and ½ cup of grated Parmesan until all cheeses are melted and creamy.

Step 5: Combine Pasta and Seafood
Add the drained macaroni and the sautéed seafood to the cheese sauce. Gently fold until everything is evenly coated with the luxurious cheese mixture. This Seafood Mac and Cheese should feel rich and indulgent, ready to take on the next delicious step.

Step 6: Prepare for Baking
If you’d like a crispy topping, preheat your oven to 375°F (190°C). Transfer the creamy seafood mac and cheese mixture into a greased baking dish. In a small bowl, combine 1 cup of panko breadcrumbs with 2 tablespoons of melted butter and 2 tablespoons of Parmesan cheese, then sprinkle this mixture evenly over the mac and cheese.

Step 7: Bake to Perfection
Bake the Seafood Mac and Cheese uncovered in the preheated oven for 20–25 minutes or until the top is golden brown and bubbly. Remove it from the oven and let it rest for about 5 minutes before serving, allowing the flavors to meld beautifully.

Make Ahead Options

These Seafood Mac and Cheese are fantastic for meal prep enthusiasts! You can assemble the entire dish, up to the baking stage, and refrigerate it for up to 24 hours. Just ensure that the seafood is cooked correctly to maintain its tender texture. When you’re ready to enjoy, simply preheat your oven to 375°F (190°C) and bake the mac and cheese for 20-25 minutes until it’s golden and bubbly. If you want to take it a step further, feel free to prep the cheese sauce and pasta separately, and store them in the fridge for up to 3 days—this way, your Seafood Mac and Cheese can be both delicious and time-saving!
