- 8 oz elbow macaroni: Classic pasta shape with just the right bite to hold the creamy sauce perfectly.

- 2 tablespoons all-purpose flour: Combines with butter to create a smooth, velvety base for the cheese sauce.
- 2 cups whole milk: Adds creamy body and helps achieve the perfect sauce consistency.
- 1/2 cup heavy cream: Boosts richness and gives the sauce an irresistibly luscious texture.
- 1 teaspoon Old Bay seasoning (optional): Offers a classic seafood spice blend that elevates every bite.
- 1/2 teaspoon garlic powder: Gives a subtle aroma and depth without overpowering the seafood.
- 1/2 teaspoon salt: Balances flavors and enhances the taste of the cheese and seafood.
- 1/4 teaspoon black pepper: Adds a gentle kick that livens up the creamy sauce.

- 1/2 lb cooked shrimp, chopped: Tender and sweet, they bring a delightful seafood bite to the dish.
- 1/2 cup lump crab meat: Adds a luxurious, delicate texture and sweet flavor.
- 1/2 cup cooked scallops or firm white fish, flaked (optional): Offers additional seafood variety and a mild ocean taste.
- 1/4 cup chopped green onions (optional): Brightens the dish with a fresh, slightly sharp contrast.

How to Make Seafood Mac and Cheese Recipe
Step 1: Cook the Pasta
Begin by preheating your oven to 375 degrees Fahrenheit. Boil the elbow macaroni in salted water until it reaches a perfect al dente texture—tender but still firm to the bite. Drain the pasta well and set it aside to keep it ready for the creamy sauce.
Step 2: Prepare the Cheese Sauce Base
In a large saucepan over medium heat, melt the butter and whisk in the flour to create a roux. Cook this mixture for about 1 to 2 minutes until it develops a light golden color, which helps cook out the raw flour taste. Slowly pour in the milk and heavy cream while whisking continuously to ensure a perfectly smooth mixture. Bring it to a gentle simmer and let it thicken over 3 to 5 minutes, stirring often to prevent burning.
Step 3: Flavor the Cheese Sauce
Add the Old Bay seasoning, garlic powder, salt, and black pepper to the thickened sauce—this seasoning blend is the secret that highlights the seafood perfectly. Stir in the shredded sharp cheddar, mozzarella, and Parmesan cheeses until every bit melts into a velvety, flavorful cheese sauce.
Step 4: Combine Pasta and Seafood
Fold the cooked pasta gently into the warm cheese sauce. Next, add the chopped shrimp, lump crab meat, and scallops or flaked white fish if you’re using them. Stir it all together until the seafood is evenly coated with the luscious sauce. Toss in chopped green onions for a fresh burst of color and mild bite.
Step 5: Bake to Perfection
Pour the creamy mixture into a greased 9-by-13-inch baking dish, spreading it out evenly. If you want that irresistible golden crust, mix panko breadcrumbs, melted butter, and Parmesan cheese together and sprinkle the topping over the mac and cheese. Bake in the preheated oven for 20 to 25 minutes until bubbly and golden on top. For an extra crispy finish, broil for 1 to 2 minutes, watching carefully so it doesn’t burn. Allow it to cool slightly before serving to let the sauce set beautifully.
How to Serve Seafood Mac and Cheese Recipe
Garnishes
To elevate the dish, try topping your seafood mac and cheese with a sprinkle of fresh parsley or additional chopped green onions. A drizzle of lemon juice or zest can add a surprising brightness that cuts through the rich cheese. For a hint of heat, a dash of smoked paprika or cayenne pepper on top creates a lovely flavor contrast.
Side Dishes
This hearty mac and cheese pairs wonderfully with simple, fresh sides. A crisp green salad with a light vinaigrette cuts through the richness, while roasted or steamed vegetables like asparagus or broccoli provide a satisfying crunch and color contrast. For a complete meal, warm crusty bread or garlic bread makes an irresistible addition to soak up every cheesy bite.
Creative Ways to Present
Serve the mac and cheese in individual ceramic ramekins for a charming, restaurant-style presentation. You could also scoop it into hollowed-out mini bell peppers or portobello mushrooms for a fun twist that adds color and texture. If you’re hosting a party, set up a mac and cheese bar with toppings like crispy bacon bits, extra cheeses, or chopped herbs so guests can customize their own plates.
Make Ahead and Storage
Storing Leftovers
Wrap leftovers tightly with plastic wrap or transfer to an airtight container and refrigerate. The mac and cheese will keep well for up to 3 days. When stored properly, the flavors actually meld together, making the leftovers even more delicious.
Freezing
You can freeze portions of this seafood mac and cheese recipe by placing it in freezer-safe containers or bags. Freeze for up to 2 months, but note that seafood texture might change slightly upon thawing. Thaw overnight in the fridge before reheating for the best results.
Reheating
Reheat leftovers gently in the oven at 325 degrees Fahrenheit until warmed through to prevent drying out. Alternatively, microwave individual servings on medium power, stirring occasionally to maintain that creamy texture. Add a splash of milk or cream if needed to revive the sauce’s silky consistency.
FAQs
Can I use different types of seafood in this recipe?
Absolutely! Feel free to swap out or add your favorite seafood like lobster, mussels, or clams. Just make sure they are cooked before mixing into the mac and cheese to ensure everything heats evenly in the oven.
Is Old Bay seasoning necessary?
Old Bay is optional but highly recommended because it gives a classic, slightly spicy seafood flavor that complements the creamy cheese perfectly. If you prefer a milder taste, you can leave it out or substitute with a pinch of smoked paprika or Cajun seasoning.
What if I want to make this recipe dairy-free?
For dairy-free versions, use plant-based milk and cream alternatives along with vegan cheese substitutes. Keep in mind that the texture and taste will be a bit different, but the dish can still be very satisfying with the seafood flavors shining through.
Can I make this without baking it?
Yes, you can skip the baking step and enjoy it straight from the stovetop after combining all the ingredients. It will be creamier and less crispy on top, but still rich and delicious.
How can I make the topping extra crispy?
Mix panko with a bit more melted butter and sprinkle a thin layer on top before broiling. Watching it closely under the broiler ensures a perfect golden crust without burning.
