- 8 oz elbow macaroni: Traditional shape perfect for holding onto the luscious cheese sauce.
- 1 lb shrimp, peeled and deveined: Adds tender seafood flavor and a nice pop of texture.
- 1/2 lb crab meat (or lobster, if preferred): Sweetness and delicate flavor to elevate the dish.
- 2 tablespoons butter: Essential for the roux and sautéing seafood, lending richness.
- 2 tablespoons flour: Thickens the sauce to that perfect creamy consistency.
- 2 cups whole milk: Creates a creamy, velvety base for the cheese sauce.
- 1 cup heavy cream: Adds indulgence and silky texture.
- 2 cups shredded sharp cheddar cheese: Sharp and tangy, the backbone of classic mac and cheese flavor.
- 1 cup shredded mozzarella cheese: Brings gooey stretch and mellow creaminess.
- 1/2 cup grated Parmesan cheese: A nutty depth that enhances the overall cheesiness.
- 1 teaspoon Dijon mustard: Gives the sauce a subtle tang to balance richness.
- 1 teaspoon garlic powder: Adds savory warmth without overpowering.

How to Make Seafood Mac and Cheese Recipe
Step 1: Cook the Pasta
Begin by boiling the elbow macaroni in generously salted water according to the package directions until it is perfectly al dente. Draining the pasta well will ensure it doesn’t become soggy once it’s mixed into the creamy sauce.
Step 2: Prepare the Seafood
Heat a tablespoon of butter in a large skillet over medium heat and sauté the shrimp until they turn pink and opaque, which usually takes about 2 to 3 minutes. Remove them from the skillet to avoid overcooking. Then, in that same skillet, cook the crab meat or lobster for an additional 2 to 3 minutes to warm through and absorb any buttery goodness. Setting both aside keeps the seafood tender and ready for the final mix.
Step 3: Make the Roux and Cheese Sauce
In a separate large saucepan, melt the remaining tablespoon of butter over medium heat. Sprinkle in the flour and whisk continuously to create a roux, cooking it until it turns golden, about 1 to 2 minutes. Slowly add the whole milk and heavy cream, whisking constantly to prevent lumps. Let the sauce thicken, which should take around 5 to 7 minutes, until it coats the back of your spoon.
Step 4: Add the Cheeses and Seasonings
Stir in the sharp cheddar, mozzarella, and Parmesan until all the cheese melts smoothly into the sauce. Then fold in the Dijon mustard, garlic powder, paprika, and season generously with salt and pepper. At this point, tasting and adjusting seasoning ensures each bite bursts with balanced flavor.
Step 5: Combine Pasta and Seafood
Gently add the cooked elbow macaroni, shrimp, and crab meat into the cheese sauce. Stir carefully to coat the pasta and seafood fully, making sure everything is heated through and perfectly blended in creamy, cheesy goodness.
Step 6: Garnish and Serve
Just before serving, sprinkle the top with freshly chopped parsley for a bright, herbal contrast. This final touch adds a lovely visual appeal and a hint of freshness to the rich dish.
How to Serve Seafood Mac and Cheese Recipe

Garnishes
Fresh parsley is a classic garnish that introduces color and a subtle herbal brightness to this seafood mac and cheese. You can also try a sprinkle of smoked paprika or a dash of cayenne pepper if you want a little kick and smoky contrast to the creamy richness.
Side Dishes
Since this Seafood Mac and Cheese Recipe feels like a hearty main course, light sides work best. Consider a crisp green salad with a lemon vinaigrette to cut through the richness or some steamed asparagus or green beans that add an earthy crunch. Garlic bread also pairs beautifully if you want to keep it extra indulgent.
Creative Ways to Present
Make your Seafood Mac and Cheese Recipe stand out by serving it in individual ramekins and topping with extra Parmesan and breadcrumbs for a golden crust under the broiler. For a family-style meal, bake it in a large casserole dish until bubbly and browned on top. Adding a drizzle of truffle oil before serving can take this comfort dish into gourmet territory.
Make Ahead and Storage
Storing Leftovers
You can store any leftover Seafood Mac and Cheese Recipe in an airtight container in the refrigerator for up to 3 days. The flavors tend to deepen overnight, making your next meal just as delicious. When storing, keeping the seafood covered and chilled is key to maintaining freshness.
Freezing
This dish can be frozen, but keep in mind that the texture of the seafood might change slightly after thawing. For best results, freeze your mac and cheese before adding the cooked seafood, then stir the seafood in after reheating. Freeze in a suitable container for up to 2 months.
Reheating
Reheat leftovers gently on the stovetop over low heat or in the microwave with a splash of milk to help restore the creamy sauce’s texture. Stir frequently to avoid overheating and to keep the seafood tender. If you baked the mac and cheese with a crust, reheating in the oven can help maintain that crisp topping.
FAQs
Can I use other types of seafood?
Absolutely! While this Seafood Mac and Cheese Recipe features shrimp and crab, feel free to swap in lobster, scallops, or even a seafood mix. Just adjust cooking times to keep your seafood tender and perfectly cooked.
What kind of cheese works best?
Sharp cheddar, mozzarella, and Parmesan create a balance of tangy, stretchy, and nutty flavors that make the sauce rich and smooth. You can experiment with Gruyere or fontina for a twist, but these classic cheeses really bring out the best in this recipe.
Is this recipe spicy?
No, the dish has a mild smoky warmth from paprika and a touch of garlic, but it isn’t spicy. You can add cayenne or hot sauce if you like a bit of heat.
Can I make this recipe gluten-free?
Yes! Use gluten-free pasta and substitute the all-purpose flour with a gluten-free flour or cornstarch to make the roux. Just follow your flour’s thickening instructions to achieve the same creamy sauce texture.
How do I ensure the seafood stays tender?
Cook the shrimp and crab only until just opaque and warmed through, removing them promptly from heat. Overcooking can make seafood tough, so add them to the cheese sauce at the end to finish warming gently.
