Ingredients
Here’s what you’ll need to whip up this divine dish:
- 8 oz elbow macaroni (or your favorite pasta shape)
- 1 cup cooked lobster meat, chopped
- 1 cup shrimp, peeled and deveined
- 2 cups sharp cheddar cheese, grated (freshly grated tastes best!)
- 1 cup mozzarella cheese, grated
- ½ cup Parmesan cheese, grated
- 4 tablespoons unsalted butter
- ¼ cup all-purpose flour
- 3 cups milk (whole milk makes it extra creamy)
- 2 teaspoons Dijon mustard
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- Salt and pepper to taste
- 1 cup panko breadcrumbs (for that perfect crunch)
- 2 tablespoons fresh parsley, chopped (for garnish)
Step-by-Step Instructions
Are you ready? Let’s make some magic happen in the kitchen!
- Preheat the oven: Start by preheating your oven to 350°F (175°C). This way, you’ll have a hot oven waiting for your delicious bake!
- Cook the pasta: In a large pot, bring salted water to a boil and cook the elbow macaroni according to package instructions until al dente. Remember, it will cook a bit more in the oven!
- Make the cheese sauce: In a separate large saucepan, melt the butter over medium heat. Add the flour and whisk continuously for about 1 minute until it’s bubbly and golden. This is your roux, which gives the sauce its thickness. Slowly whisk in the milk until smooth. Continue cooking on medium heat, stirring often, until the mixture thickens, about 5-7 minutes.
- Add the good stuff: Once thickened, remove the saucepan from heat and stir in the Dijon mustard, garlic powder, onion powder, and a sprinkle of salt and pepper. Now, mix in the cheddar, mozzarella, and half of the Parmesan cheese until melted and creamy.
- Combine everything: Drain the pasta and add it to the cheese sauce. Gently fold in the lobster and shrimp, being careful not to overmix those tender treasures. You want them to stay nice and chunky!
- Transfer and top: Pour the mixture into a greased baking dish (about 9×13 inches). In a small bowl, mix the panko breadcrumbs with the remaining Parmesan cheese and sprinkle it evenly over the top. This will give your dish that irresistible crunch!
- Bake to perfection: Bake in the preheated oven for about 25-30 minutes, or until the top is golden and bubbling. Your kitchen will smell like pure heaven while it bakes!
- Garnish and serve: Once out of the oven, sprinkle with fresh parsley for a pop of color and freshness. Let it cool for a few minutes before diving in!

Pro Tips & Variations
Now, let’s chat about how you can have fun with this recipe!
- Seafood Swap: Don’t have lobster? No problem! You can swap it for crab meat, or go for a mix of seafood like mussels and scallops.
- Spicy Kick: If you love a bit of heat, throw in some red pepper flakes or a splash of hot sauce in the cheese sauce.
- Veggie Love: Want to sneak in some veggies? Fresh spinach or peas can jazz up the dish without taking away from the star seafood!
- Cheesy Goodness: Feel free to experiment with different cheeses. Gruyère or fontina can add a lovely depth of flavor.
- Herb Infusion: Add fresh thyme or dill for an herby note that complements the seafood beautifully.

Serving Suggestions
There’s nothing quite like gathering around the table and enjoying this Seafood Mac & Cheese Bake with friends and family. I love serving it alongside a fresh green salad—think crisp romaine with a tangy vinaigrette to balance the richness of the dish. A warm, crusty loaf of garlic bread or buttery dinner rolls makes it even cozier. Trust me, you’ll want something to scoop up any leftover cheesy goodness!
And don’t forget a chilled glass of white wine or a refreshing iced tea to wash it all down. That combination truly makes for a delightful evening, reminiscent of long summer nights by the beach.

Storage Tips
Want to enjoy this dish throughout the week? You can easily store leftovers! Allow the Seafood Mac & Cheese Bake to cool completely before transferring it to an airtight container. You can refrigerate it for up to 3 days.
If you’re thinking of freezing it, cover it tightly with plastic wrap and then foil to prevent freezer burn. It can be frozen for up to 3 months. When you’re ready to enjoy, simply thaw it in the fridge overnight and reheat in the oven at 350°F (175°C) until heated through. Take care not to overheat as it can dry out—nobody wants that!
FAQs
Can I make this dish ahead of time?
Absolutely! You can prepare the Seafood Mac & Cheese Bake up to the point of baking, cover it, and refrigerate it overnight. Just add a few extra minutes to the baking time when you’re ready to cook it. It’s a great option for meal prep or hosting!
What can I use instead of seafood?
If seafood isn’t your thing or you’re feeding someone with allergies, you can easily replace it with cooked chicken, cooked mushrooms, or even go meatless and add in some extra veggies like broccoli or bell peppers.
Can I use gluten-free pasta?
You sure can! Just swap the elbow macaroni for your favorite gluten-free pasta. Ensure that your flour for the roux is also gluten-free, and you’re all set!
How do I prevent it from being dry?
A few things can help keep your Seafood Mac & Cheese nice and creamy. First, don’t overbake it! Keep an eye on it during the last few minutes. If your sauce seems a bit thick, you can add a splash of milk before baking to keep it luscious.
