Step‑by‑Step Instructions for Seafood Mac and Cheese

Step 1: Cook the Pasta
Bring a large pot of salted water to a boil, then add 1 pound of elbow macaroni. Cook until the pasta is al dente, usually around 7–8 minutes, stirring occasionally. Once done, drain the pasta and set it aside in a large mixing bowl, allowing it to cool slightly while you prepare the seafood and sauce.

Step 2: Sauté Seafood
In a skillet, heat 1 tablespoon of olive oil or butter over medium heat. Add the ½ pound of shrimp and ½ pound of scallops, cooking for about 2–3 minutes per side until they turn opaque. Gently fold in the ½ pound of lump crab meat and season with a pinch of salt and pepper, then remove from heat and set aside to let the flavors meld.

Step 3: Make the Roux
In a medium saucepan over medium heat, melt 4 tablespoons of unsalted butter. Whisk in ¼ cup of all-purpose flour and cook for 1–2 minutes until it forms a smooth, pale roux. This step is crucial for thickening your cheese sauce, so keep whisking to avoid browning the mixture too much.

Step 4: Build the Sauce
Gradually whisk in 4 cups of warmed whole milk and 1 cup of heavy cream, continuing to stir as the mixture thickens, about 5–7 minutes. Once it’s smooth, add 2 teaspoons of Dijon mustard, 1 teaspoon of Old Bay seasoning, ½ teaspoon of garlic powder, ½ teaspoon of salt, and ¼ teaspoon of black pepper to enhance the flavor profile of your Seafood Mac and Cheese.

Step 5: Add Cheese
Remove the saucepan from heat and fold in 2 cups of shredded sharp cheddar cheese, 1 cup of shredded Gruyère cheese, and ½ cup of grated Parmesan cheese. Stir until the cheeses are fully melted and the sauce is rich and creamy, creating that perfect cheesy base for the seafood and pasta to shine.

Step 6: Combine Ingredients
In that large bowl with the drained macaroni, pour the creamy cheese sauce over it, followed by the sautéed seafood mixture. Gently mix everything until all the pasta and seafood are evenly coated with that luxurious sauce, ensuring each bite will be bursting with flavor.

Step 7: Prepare Topping
In a small bowl, combine 1 cup of panko breadcrumbs with 2 tablespoons of melted butter and 2 tablespoons of Parmesan cheese, if using. Mix well to ensure the breadcrumbs are evenly coated; this will create a deliciously crispy topping that enhances the richness of your Seafood Mac and Cheese.

Step 8: Bake the Dish
Transfer the seafood pasta mixture into a greased baking dish, spreading it evenly. Top generously with the breadcrumb mixture and place the dish in an oven preheated to 375°F (190°C). Bake for about 20–25 minutes, or until the top is golden brown and the edges are bubbling, signaling that your Seafood Mac and Cheese is nearly ready.

Step 9: Serve and Enjoy
Once baked, remove the dish from the oven and let it rest for 5 minutes. This resting period allows the flavors to settle, making each serving even more delightful. Scoop generous portions onto plates and savor every creamy, seafood-flavored bite of your homemade Seafood Mac and Cheese.

How to Store and Freeze Seafood Mac and Cheese

Fridge: Store leftovers in an airtight container for up to 3 days. This ensures your Seafood Mac and Cheese stays fresh and delicious for a few days.

Freezer: You can freeze the dish for up to 2 months. Portion it into freezer-safe containers, and wrap tightly to prevent freezer burn.

Reheating: For best results, reheat in the oven at 350°F (175°C), adding a splash of cream on top to restore creaminess. This brings your Seafood Mac and Cheese back to life!

Make-Ahead Tip: Assemble the dish up to the baking step, refrigerate, and bake just before serving for fresh flavors and comforting warmth.

Make Ahead Options

These Seafood Mac and Cheese are a dream for busy home cooks! You can prepare the dish up to 24 hours in advance by following these simple steps: assemble the macaroni, cheese sauce, and sautéed seafood, then transfer it into a greased baking dish. Cover tightly with plastic wrap and refrigerate until you’re ready to cook. For the best quality, avoid adding the breadcrumb topping until you’re about to bake it, as this keeps it crispy.

Helpful Tricks for Seafood Mac and Cheese

  • Cheese Quality Matters: Use fresh, block cheeses rather than pre-shredded. Shredding your own prevents graininess and ensures a smooth, creamy texture in your Seafood Mac and Cheese.

  • Don’t Overcook Seafood: When sautéing, cook shrimp and scallops just until opaque. Overcooking can lead to tough seafood, ruining the dish’s delicate flavors.

  • Preheat for Perfection: Make sure your oven is fully preheated before baking. This ensures even cooking and a beautifully golden, crispy topping on your Seafood Mac and Cheese.

  • Adjust Seasonings Carefully: Taste the cheese sauce before mixing in the seafood. This allows you to adjust salt and spices, ensuring a well-balanced flavor throughout.

  • Rest Before Serving: Allowing the dish to sit for about 5 minutes after baking helps the flavors meld together, leading to a more harmonious bite in each serving.
