This rich Seafood Mac and Cheese recipe combines elbow macaroni and a creamy cheese sauce packed with your favorite seafood and baked to a bubbly finish.
Preheat oven to 400°F. Grease a 9x13-inch baking dish with melted butter or cooking spray and set aside.
Cook the pasta following the package instructions until almost al dente (about 2 minutes less than the cooking time indicated on the package). Drain and transfer the pasta to the baking dish. Lightly drizzle with olive oil to prevent sticking and set aside.
In a small bowl, combine panko breadcrumbs, grated Parmesan, chopped fresh parsley, butter, and sea salt. Mix well and set aside.
Heat the olive oil and butter in a large, deep skillet over medium heat.
Add the minced garlic to the skillet and cook for 20 seconds or until fragrant.
Whisk in flour and cook for 1 minute, whisking constantly, until the mixture turns a light brown, about 2 to 3 minutes. Lower the heat.
Slowly pour in the milk, stirring constantly until the mixture begins to thicken. Then, add in half and half, and continue to whisk until combined and smooth.
Season with salt, pepper, and nutmeg, then simmer for 2 to 3 minutes until thickened.
Remove the skillet from the heat. Stir in Gruyere and Parmesan cheeses, whisking until completely smooth. The sauce should be smooth and creamy.
Gently fold the coarsely chopped cooked seafood (lobster, shrimp, crawfish, or crabmeat) into the cheese sauce.
Pour the seafood cheese mixture over the pasta in the baking dish. Stir until well combined.
Sprinkle the prepared Parmesan breadcrumb mixture evenly over the top.
Bake in the preheated oven for 25 to 30 minutes or until the top is golden and the cheese is bubbling.
Remove from the oven and let it rest for 5 minutes. Garnish with fresh parsley before serving.
Notes
Cook pasta to al dente; avoid overcooking as it'll cook further in the oven.
Mix up the seafood! Simple crab or a mix of crab, lobster, and shrimp both work great.
Frozen seafood is fine. Just defrost according to the package before using.
Spice it up with sausage or chopped ham for added flavor and heartiness.
Add peas and corn for extra texture and color to your mac and cheese.
Store seafood mac and cheese in an airtight container in the fridge for up to 3 days or freeze for up to 3 months. Thaw well before reheating.
Reheat in the microwave in 30-second bursts or the oven at 325°F until hot.
