How to Make Seafood Mac & Cheese: The Best Ever Creamy Recipe You’ll Love Recipe
Step 1: Prepare for baking
Start by preheating your oven to 375°F (190°C) and greasing a 9×9-inch baking dish. This makes clean-up easier and ensures your mac and cheese won’t stick.
Step 2: Cook the pasta
Boil the elbow macaroni according to the package instructions until it’s perfectly al dente—firm but tender enough to soak up that luscious sauce. Drain and set aside, ready for the cheesy goodness.
Step 3: Make the roux
In a large saucepan over medium heat, melt butter and whisk in flour constantly for 1 to 2 minutes. This step is key for creating a smooth base that thickens your sauce, giving it that creamy texture you crave.
Step 4: Create the cheese sauce
Slowly whisk in the warm milk and heavy cream, stirring often to prevent lumps. Cook for about 5 to 7 minutes until the sauce thickens beautifully to coat the back of a spoon—this means it’s ready for the cheeses.
Step 5: Add the cheeses and seasonings
Remove the sauce from heat and stir in sharp cheddar, mozzarella, and Parmesan until melted and silky. Sprinkle in garlic powder, Old Bay seasoning, salt, and black pepper for that unforgettable depth of flavor.
Step 6: Combine pasta and seafood
Gently fold the cooked pasta, chopped shrimp, and crab meat into the cheese sauce, ensuring every bite will be packed with creamy, seafood-infused delight.
Step 7: Assemble and bake
Pour the mixture into your prepared baking dish. For a crunchy top, sprinkle breadcrumbs evenly over the surface if you’re using them. Pop it in the oven and bake uncovered for 18 to 20 minutes until the top is bubbly and lightly golden.
Step 8: Garnish and serve
Once out of the oven, sprinkle with fresh chopped parsley for a lovely pop of color and a hint of brightness. Serve hot and prepare for everyone to be wowed.

Garnishes
Fresh parsley is a classic choice, adding just the right freshness and a vibrant green contrast. For an extra touch, try a squeeze of lemon juice or a dusting of paprika to highlight those beautiful seafood flavors.
Side Dishes
This creamy seafood mac pairs beautifully with crisp, simple sides like a fresh arugula salad with a light vinaigrette or steamed green beans for a crisp bite. Roasted asparagus also complements the rich flavors wonderfully.
Creative Ways to Present
For a fun twist, serve individual portions in small ramekins or mini cast-iron skillets for an elegant look. You can also scoop it into buttery puff pastry shells for an impressive appetizer or party snack.
Make Ahead and Storage
Storing Leftovers
Let your Seafood Mac & Cheese cool completely before transferring to an airtight container. It will keep well in the refrigerator for up to 3 days, making it perfect for quick reheats during the week.
Freezing
If you want to save it for longer, freeze the mac and cheese uncovered until solid, then cover tightly with foil or plastic wrap. It should keep nicely for up to 2 months. Just thaw overnight in the fridge before reheating.
Reheating
Reheat leftovers gently in the oven at 350°F (175°C) covered with foil to prevent drying out. You can also microwave individual portions but add a splash of milk to keep that sauce creamy and rich.
FAQs
Can I use other types of seafood?
Absolutely! Feel free to mix in cooked lobster, scallops, or even smoked salmon to personalize your mac and cheese. The cheese sauce pairs wonderfully with a variety of seafood flavors.
What can I substitute for elbow macaroni?
Any pasta shape you like will work well—shells, cavatappi, or penne all hold the sauce beautifully. Just stick with something that has nooks and crannies for maximum deliciousness.
Is there a way to make this recipe dairy-free?
Yes! Use dairy-free butter and milk alternatives like almond or oat milk, and swap out the cheeses for dairy-free versions. Keep in mind the texture and flavor will be different but still tasty.
Can I make this recipe ahead of time?
Definitely! Prepare the mac and cheese through Step 6, then refrigerate before baking. When you’re ready, bake it fresh—this helps keep the topping nice and crunchy.
How spicy is the Old Bay seasoning in this recipe?
Old Bay adds a warm, slightly spicy, and savory complexity without overwhelming heat. It enhances the seafood flavor beautifully and most people find it perfectly balanced.
