The magic of this Seafood Mac and Cheese lies in its simple, yet carefully chosen ingredients. Each one plays its part to create layers of flavor, the perfect creamy texture, and that stunning golden color that makes this dish irresistible.

12 ounces rotini pasta or elbow macaroni: These shapes hold cheese sauce beautifully, ensuring every forkful is luscious and satisfying.
4 lobster tails (about 1 pound): Tender and sweet, lobster adds a luxurious seafood richness that elevates the entire dish.
4 cups chicken or vegetable stock: Adds depth and subtle savory notes, making the cheese sauce even more flavorful.
2 cups water: Helps cook the seafood gently and balances the sauce consistency.
1 pound large raw shrimp (21-25 count), peeled, deveined, tails removed: Adds a succulent, delicate texture and bright seafood flavor.
2 cups whole milk: Essential for a creamy, smooth cheese sauce without overpowering richness.
2 tablespoons butter: Brings richness and creates a silky roux when combined with flour.
2 tablespoons all-purpose flour: The thickening agent that turns milk into a velvety béchamel sauce.
8 ounces fontina cheese, shredded: Melts beautifully, lending a mild, buttery flavor and stretchiness.
4 ounces mild cheddar cheese, shredded: Offers sharpness and classic mac and cheese appeal, balancing the creaminess.
¼ teaspoon freshly grated nutmeg: A subtle secret ingredient that adds warmth and complexity.
Salt and pepper, to taste: Necessary for seasoning and enhancing all the distinct flavors.
Fresh parsley and chives for garnish: Brighten the dish with fresh herbal notes and a pop of color.

How to Make Seafood Mac and Cheese with Lobster and Shrimp Recipe

Step 1: Cook the Pasta

Bring a large pot of salted water to a rolling boil and cook the rotini or elbow macaroni until just al dente, about 8 minutes. Drain and set aside, reserving a little pasta water to loosen the sauce later if needed. The pasta’s firmness is critical here because it will cook a bit more when mixed with the sauce, so avoid overcooking.

Step 2: Prepare the Lobster and Shrimp

In a large skillet or saucepan, combine the chicken or vegetable stock and water and bring to a simmer. Add the lobster tails and poach gently for about 6-7 minutes until they turn bright red and the meat is opaque. Remove lobster, let cool slightly, then cut the meat into bite-sized chunks. Next, add the shrimp to the simmering broth and cook for about 2-3 minutes until pink and opaque. Drain shrimp and set aside.

Step 3: Make the Cheese Sauce Base

In a separate large saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes until the mixture is bubbly and golden—this is your roux. Slowly whisk in the whole milk, making sure the sauce stays smooth. Cook, stirring constantly, until the sauce thickens and coats the back of a spoon.

Step 4: Add Cheese and Seasoning

Reduce the heat to low and stir in the shredded fontina and mild cheddar cheeses until melted and silky. Sprinkle in the freshly grated nutmeg and season with salt and pepper to taste. This rich, creamy cheese sauce is where all the magic truly happens.

Step 5: Combine Seafood, Pasta, and Sauce

Gently fold the lobster chunks, shrimp, and drained pasta into the cheese sauce. If it feels too thick, add a splash of the reserved pasta water to loosen it to your liking. Stir just enough to combine everything evenly without breaking up the seafood.

Garnishes

Fresh parsley and chives sprinkled on top bring a lovely herbaceous brightness and an inviting green contrast to the creamy golden mac and cheese. Not only do they add flavor, but they also make the presentation pop, making every bite feel special.

Side Dishes

This dish is rich and satisfying on its own, but pairing it with a crisp, refreshing side can balance the meal beautifully. Try a simple mixed greens salad with a light vinaigrette or some steamed asparagus with lemon zest for a bright, fresh counterpoint.

Creative Ways to Present

For a crowd-pleasing presentation, serve the mac and cheese in individual ramekins topped with a sprinkle of panko breadcrumbs and broil briefly to create a golden crust. You could also add a drizzle of browned butter or a touch of truffle oil for an extra indulgent twist.

Make Ahead and Storage

Storing Leftovers

You can store any leftovers in an airtight container in the refrigerator for up to 3 days. To maintain the best texture, cool it quickly and avoid leaving it out at room temperature for long periods.

Freezing

While mac and cheese can be frozen, the texture of the seafood may change slightly after thawing. If you want to freeze, do so without the garnish and use a freezer-safe container. It’s best enjoyed within 1 month.

Reheating

Reheat gently on the stovetop over low heat, adding a splash of milk to bring back creaminess. Stir frequently until warmed through. Avoid microwaving for long periods as it can make the sauce separate and the seafood rubbery.

FAQs

Can I use frozen lobster and shrimp for this recipe?

Absolutely! Just be sure to thaw them completely before cooking. Using fresh seafood is great, but frozen seafood works well and is often more accessible.

What type of cheese works best in seafood mac and cheese?

Can I make this recipe gluten-free?

Yes, you can substitute the all-purpose flour with a gluten-free flour blend or cornstarch to thicken the sauce. Make sure your pasta is gluten-free as well.

While not absolutely critical, a pinch of freshly grated nutmeg adds a subtle warmth and complexity that elevates the cheese sauce remarkably, so it’s worth including if you can.
