Seafood mac and cheese is my go-to comfort dish when I want to wow family and friends with minimal effort. Creamy cheese sauce hugs every piece of pasta and decadent seafood turns this classic into something truly special. It is perfect for both weeknights and holidays when you crave something indulgent but simple to prepare.
When I first made this for family, I watched it vanish from the serving dish in minutes. My little brother even requested it as his birthday dinner last year and still talks about it.
Ingredients
- Elbow macaroni or any favorite short pasta: The shape holds all that glorious sauce and makes every bite cheesy. Look for bronze-cut pasta for the best texture.
- Shredded sharp cheddar cheese: The bold flavor forms the base of the sauce. Choose a block and shred it yourself for smooth melting.
- Shredded mozzarella cheese: This cheese gives a gooey stretchy quality and creamy finish. Look for low moisture mozzarella for best melting.
- Milk either whole or two percent: For a rich sauce that does not separate use fresh cold milk.
- Butter: Essential for starting the roux and adding a subtle richness. Use real butter not margarine.
- All-purpose flour: Helps thicken the sauce so it coats every noodle. Fresh flour mixes more smoothly.
- Garlic powder: Gives a savory kick in every bite. Make sure yours smells pungent and fresh.
- Onion powder: Adds warmth and a little sweetness to balance the flavors.
- Smoked paprika (optional): If you want a hint of smokiness reach for genuine Spanish smoked paprika.
- Salt and pepper: As always taste and adjust as you go for the best flavor.
- Cooked seafood mix (shrimp, crab, scallops or any combination): If you buy frozen thaw completely and dry well so the sauce stays creamy.
- Grated Parmesan cheese: The golden crispy topping that seals in the flavor. Always grate the cheese fresh for the punchiest taste.
- Fresh parsley or chives for garnish: Adds bright color and fresh flavor at the end.
Instructions
- Cook the Pasta:
- Boil your macaroni in a large pot of well-salted water until just al dente It should be soft with a tiny bite in the center Drain thoroughly and set aside The pasta will finish cooking in the sauce so do not overcook
- Make the Cheese Sauce:
- Place a large saucepan over medium heat and add the butter Once melted sprinkle in the flour Whisk constantly for about two minutes until the mixture is bubbling and just starting to smell nutty This roux ensures your cheese sauce will be thick and silky
- Add the Milk and Thicken the Sauce:
- Slowly pour in the milk whisking the whole time so no lumps form Raise the heat to medium-high and keep stirring patiently until the sauce bubbles and thickens enough to coat the back of a spoon This process can take about five minutes and patience is key for the perfect texture
- Melt in the Cheeses and Seasonings:
- Drop the heat to low and start adding your shredded cheddar and mozzarella Bit by bit whisk until fully melted After that sprinkle in garlic powder onion powder smoked paprika salt and pepper Keep stirring until the sauce is smooth and glossy The fragrance is your sign to taste and adjust seasoning
- Combine Pasta and Seafood:
- Gently fold in the cooked seafood being careful not to break up tender pieces Add warm drained pasta into the cheese sauce and stir completely so every morsel is cloaked with the creamy goodness
- Time to Bake:
- If you want a bubbly golden finish transfer everything to a greased baking dish Scatter grated Parmesan and a little more cheddar over the top Place in a preheated oven at three hundred fifty degrees and bake for twenty minutes until everything is melted together and the top is beautifully browned
- Garnish and Serve:
- Pull from the oven and let it rest for five minutes Sprinkle chopped parsley or chives right before serving for a fresh note

The mozzarella is my secret weapon for velvety texture. I always remember my niece wide-eyed as those cheesy strings stretched across her plate. Memories like that turn a recipe into a family tradition.
Storage Tips
Let leftovers cool completely then pack into airtight containers and refrigerate You can also freeze portions for up to three months Thaw in the fridge overnight and reheat gently in the oven or microwave adding a splash of milk to loosen if needed
Ingredient Substitutions
No seafood on hand Try roasted chicken cooked bacon or even sautéed mushrooms for a twist If sharp cheddar is too bold go for mild cheddar or add a touch of cream cheese for more richness Gluten free pasta works just as well adjust the cooking time so it holds its shape
Serving Suggestions
Pair with garlicky sautéed greens or a crisp salad I love serving with warm crusty bread to mop up every last bit This dish is also a favorite side at holiday dinners where it disappears faster than the main event
