Ingredients

12 oz elbow macaroni
6 oz cooked lobster meat, chopped (tail and claw meat preferred)
6 oz lump crab meat, picked over for shells
8 oz medium shrimp, peeled, deveined, and chopped
1 tablespoon butter
1 clove garlic, minced
Salt and pepper, to taste

For the cheese sauce:

4 tablespoons unsalted butter
1/4 cup all-purpose flour
3 cups whole milk (warm)
1 cup heavy cream
1/2 teaspoon Dijon mustard
1/2 teaspoon Old Bay seasoning (optional, for extra flavor)
Salt and freshly cracked black pepper, to taste
1/2 teaspoon paprika
2 cups sharp cheddar cheese, shredded
1 cup Gruyère cheese, shredded
1/2 cup mozzarella cheese, shredded
1/2 cup Parmesan cheese, finely grated

For the topping:

1/2 cup panko breadcrumbs
1 tablespoon butter, melted
2 tablespoons Parmesan cheese
Chopped parsley, for garnish (optional)

Instructions

1
Bring a large pot of salted water to a boil. Cook the macaroni according to package directions until al dente. Drain and toss with a tiny bit of oil to prevent sticking. Set aside.
2
In a medium skillet, melt 1 tablespoon of butter over medium heat. Add the minced garlic and cook for about 30 seconds until fragrant. Add the shrimp, season with a pinch of salt and pepper, and cook for about 2–3 minutes until pink and opaque. Add the chopped lobster and crab meat, stir gently just to warm through for another 1–2 minutes. Remove from heat and set aside.
3
In a large saucepan, melt 4 tablespoons of butter over medium heat. Whisk in the flour to create a roux and cook for 1–2 minutes, whisking constantly until golden and bubbling. Gradually add the warm milk and cream, whisking to remove lumps. Continue whisking and cook until the sauce thickens, about 5–7 minutes.
4
Stir in Dijon mustard, paprika, Old Bay (if using), salt, and pepper. Then slowly add in all the cheeses (reserving some Parmesan for the topping), stirring until melted and velvety smooth. Taste and adjust seasoning if needed.
5
Preheat oven to 375°F (190°C). In a large mixing bowl or directly in a greased 9x13-inch baking dish, combine the cooked pasta, seafood mixture, and cheese sauce. Stir gently to coat the pasta and seafood evenly with the sauce. Be careful not to break up the crab too much.
6
In a small bowl, mix the panko breadcrumbs with melted butter and the remaining Parmesan. Sprinkle this mixture evenly over the top of the macaroni.
7
Place the dish in the preheated oven and bake for 20–25 minutes, or until the top is golden brown and the sauce is bubbly. For a crispier topping, broil for the last 1–2 minutes, watching carefully to avoid burning.
8
Remove from oven and let rest for 5 minutes. Garnish with chopped parsley if desired. Serve warm, and enjoy this rich, cheesy, seafood-packed comfort dish!

Note

Lobster, crab, and shrimp macaroni and cheese is the ultimate indulgence—rich, creamy, and packed with tender seafood and gooey cheese.

Elevating a comfort food classic with luxurious ingredients makes it perfect for special occasions or an impressive dinner. Here’s how to perfect this dish with practical tips, clever tricks, and serving ideas.

1. Choose Quality Seafood

The success of this dish lies in using fresh, high-quality seafood.

Lobster: Use claw and tail meat for a balance of tenderness and flavor. If whole lobster is too expensive or hard to find, pre-cooked frozen lobster meat is a good alternative.
Crab: Look for lump crab meat—it holds together well and has a sweet, clean flavor. Avoid imitation crab.
Shrimp: Use medium to large shrimp, peeled and deveined. Chop into bite-sized pieces and avoid overcooking.

Tip: Pre-cook the seafood just until opaque; it will finish cooking in the oven and stay tender instead of rubbery.

2. Perfect the Cheese Sauce

The cheese sauce should be velvety and flavorful, complementing the seafood without overpowering it.

Cheeses to use: A combination works best. Use sharp cheddar for classic flavor, Gruyère for creaminess, and a bit of Parmesan for a savory edge.
Avoid stringy cheeses: Mozzarella or too much American cheese can make the texture gummy.
Make a roux: Start with butter and flour to make a roux, then whisk in milk or half-and-half to create a smooth béchamel sauce before adding cheese.

Trick: Add a splash of white wine or seafood stock to the sauce for depth of flavor and a subtle oceanic note.

3. Season with Balance

Seafood is delicate, so season thoughtfully.

Essential spices: Garlic powder, onion powder, smoked paprika, and a touch of cayenne for mild heat.
Salt carefully: The seafood and cheese both add saltiness. Taste as you go.
Freshness counts: A squeeze of lemon juice or a sprinkle of zest can brighten up the dish beautifully.

Pro Tip: A touch of Old Bay seasoning brings a coastal flavor that enhances crab and shrimp.

4. Choose the Right Pasta

Elbow macaroni is traditional, but other shapes work well too.

Best shapes: Cavatappi, shells, or penne—anything with ridges to hold the sauce.
Cook al dente: Since the pasta will bake, slightly undercook it during boiling to avoid mushy texture.

5. Top It Right

A golden, crunchy topping adds essential contrast to the creamy base.

Breadcrumbs: Use panko mixed with melted butter and a little grated cheese for the best crunch.
Extra flavor: Mix in dried herbs like thyme or parsley for a gourmet touch.

6. Bake with Care

Use a buttered or sprayed baking dish to prevent sticking.
Cover with foil for the first 15–20 minutes, then uncover to brown the top.
Let rest 10 minutes after baking so the sauce can set slightly.

7. Serving Tricks

Portion smart: It’s rich, so serve with a simple side like a green salad or roasted vegetables.
Make ahead: Assemble everything up to a day in advance, refrigerate, and bake before serving.
Individual servings: Bake in ramekins or mini cocottes for dinner parties or special presentations.

Presentation Tip: Garnish with fresh herbs (chives, parsley), a drizzle of truffle oil, or a lemon wedge on the side for a professional finish.

Tips and Variations:

Seafood Swaps: You can use just one or two types of seafood if desired, such as only lobster or shrimp. Scallops also work well.
Cheese Choices: Sharp cheddar and Gruyère offer great meltability and depth. You can also try Fontina, Havarti, or a touch of blue cheese for stronger flavor.
Breadcrumb Boost: For an extra crunch, mix the panko with crushed Ritz crackers or add finely chopped herbs like thyme or chives.
Make-Ahead: You can assemble the casserole up to a day ahead, cover tightly, and refrigerate. Bake just before serving.

Serving Suggestions:

Pair this seafood mac and cheese with a simple green salad or roasted asparagus for balance. A crisp white wine like Chardonnay, Sauvignon Blanc, or a sparkling Prosecco complements the richness beautifully.

Storage:

Refrigerator: Store leftovers in an airtight container for up to 3 days.
Reheat: Warm gently in the oven at 350°F (175°C) covered with foil or microwave in short intervals with a splash of milk to keep it creamy.
Freezing: Not recommended for best texture, but possible before baking. Assemble, freeze, and bake from frozen at 350°F (covered) for 60–70 minutes.
