Mac and cheese is already terrific on its own, but it’s truly decadent with the addition of seafood! Lobster or shrimp work best. This Seafood Mac and Cheese takes the classic comfort food to new heights, combining a rich, creamy cheese sauce with tender pasta and luxurious pieces of lobster, crab, or shrimp. Topped with golden, buttery breadcrumbs, this dish is perfect for special occasions, holiday dinners, or anytime you want to impress.
Why This Recipe Works
This recipe succeeds because it follows the classic method for creating a velvety, restaurant-quality cheese sauce. The Gruyère and sharp cheddar provide the perfect balance of nutty, sharp, and melty flavors. The whole milk and heavy creamcreate a rich, luxurious base. The roux(butter and flour) ensures a smooth, stable sauce that won’t separate. The seafood adds elegance and a touch of sweetness that pairs beautifully with the creamy cheese. And the panko breadcrumb topping adds a delightful crunch.
The Complete Recipe: Seafood Mac and Cheese
Ingredients
-
1 lb elbow macaroni
-
½ cup unsalted butter, divided
-
½ cup flour
-
3 cups whole milk, room temperature
-
1 cup heavy cream, room temperature
-
4 cups grated Gruyère cheese
-
2 cups grated sharp cheddar cheese
-
1 teaspoon coarse salt
-
1½ lb cooked lobster, crab, and/or shrimp, etc.
-
1 cup panko breadcrumbs
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Coat a 2-quart baking dish with cooking spray or lightly coat it with butter.
Step 2: Cook the Pasta
Cook the pasta just to al dente, according to the package directions. Drain and set aside.
Step 3: Make the Cheese Sauce
Meanwhile, melt 6 tablespoons of the butter in a large pot over medium heat. Add the flour, then whisk constantly until it’s fully combined, about 30 seconds. Slowly add the milk and cream, whisking constantly, until it’s combined and smooth, about one minute more. Reduce the heat to low.
Stir in the shredded cheeses, one handful at a time, stirring to combine completely between additions. Remove from the heat.
Step 4: Combine Pasta and Seafood
Gently stir in the cooked pasta and seafood until everything is well coated in the cheese sauce. Pour the mixture into the prepared baking dish.
Step 5: Prepare the Topping
Melt the remaining 2 tablespoons of butter and mix it with the panko breadcrumbs. Sprinkle them evenly on top of the mac and cheese.
Step 6: Bake
Bake for about 30 minutes, or until the seafood mac and cheese is hot throughout and the breadcrumbs are golden brown.
Step 7: Serve
Serve immediately.
Pro Tips for the Best Seafood Mac and Cheese
-
Room Temperature Dairy: Using room temperature milk and cream helps the sauce come together smoothly and prevents lumps.
-
Don’t Overcook the Pasta: Cook just to al dente—the pasta will continue cooking in the oven.
-
Freshly Grate Your Cheese: Pre-shredded cheese contains anti-caking agents that can prevent smooth melting. Grate your own for the creamiest sauce.
-
Seafood Choice: Lobster, shrimp, and crab are all excellent. You can use one or a combination. Make sure it’s cooked before adding.
-
Panko Perfection: For extra flavor, you can add grated Parmesan or chopped parsley to the breadcrumb topping.
Delicious Variations
-
Lobster Mac: Use only lobster for an extra-luxurious version.

Shrimp Scampi Mac: Add garlic and lemon zest to the breadcrumb topping.
