Lobster, Crab, and Shrimp Macaroni and Cheese Ingredients
For the Pasta
- Elbow Macaroni – A classic choice that provides structure and chewiness; substitute gluten-free elbow macaroni for a lighter option.
For the Seafood Medley
- Lobster Meat – Adds sweet, succulent richness; fresh or frozen lobster works wonderfully for this indulgent dish.
- Crab Meat – Enhances the seafood ensemble with its mild sweetness and tender texture; fresh lump crab meat is preferred for the best flavor.
- Shrimp – Contributes a delightful briny flavor and firm bite; opt for peeled and deveined shrimp to save time.
For the Cheese Sauce
- Cheddar Cheese – Provides a sharp and creamy base; for an ultra-smooth sauce, grate your own cheese to avoid additives.
- Gruyère Cheese – Adds a nutty flavor and satiny texture; Swiss cheese can be used as a substitute if needed.
For the Creaminess
- Milk – Forms the base of the sauce; this is where the creaminess begins!
- Heavy Cream – Enhances richness; half-and-half can be used for a lighter take on the sauce if desired.
- Butter – Brings richness to the roux; I recommend unsalted butter for better control over the dish’s seasoning.
- All-Purpose Flour – Thickens the sauce beautifully; for a gluten-free variation, replace it with rice flour or cornstarch.
For Seasoning
- Salt – Enhances all the flavors; remember to use it sparingly as the seafood is naturally salty.
- Pepper – Freshly ground black pepper elevates the dish; a pinch goes a long way!
- Nutmeg – A dash of nutmeg adds warmth and depth; it’s the secret ingredient that elevates the overall taste.
Step‑by‑Step Instructions for Lobster, Crab, and Shrimp Macaroni and Cheese
Step 1: Cook the Pasta
Begin by boiling a large pot of salted water. Add elbow macaroni once the water reaches a rolling boil, and cook until al dente, usually about 7–8 minutes. Drain the pasta thoroughly in a colander and return it to the pot, tossing it lightly to prevent sticking while you prepare the creamy seafood sauce.
Step 2: Make the Sauce
In a medium saucepan, melt 4 tablespoons of unsalted butter over medium heat until bubbly. Whisk in 1/4 cup of all-purpose flour, stirring constantly for about 2–3 minutes to create a smooth roux. Gradually pour in 2 cups of milk and 1 cup of heavy cream, whisking continuously. Cook until the mixture thickens and coats the back of a spoon, approximately 5 minutes after it begins to simmer.
Step 3: Add Cheese
Remove the saucepan from heat and stir in 2 cups of grated cheddar cheese and 1 cup of Gruyère cheese. Mix until all the cheese has melted, creating a rich, creamy sauce. If the sauce is too thick, you can add a splash of milk to reach your desired consistency. The smooth and cheesy sauce should glisten temptingly as you prepare to incorporate the seafood.
Step 4: Prepare the Seafood
Gently fold in 1 cup of cooked lobster meat, 1 cup of lump crab meat, and 1 cup of peeled and deveined shrimp into the cheese sauce. Season with salt, freshly cracked pepper, and a pinch of nutmeg to enhance the flavors. Ensure that the seafood is evenly coated in the creamy sauce, creating a luxurious base for your Lobster, Crab, and Shrimp Macaroni and Cheese.
Step 5: Combine Everything
Pour the seafood cheese sauce over the cooked elbow macaroni in the pot, stirring thoroughly to combine. Ensure the macaroni is evenly coated with the cheesy seafood mixture. This step is vital to bring together all the flavors, creating a decadent dish that will delight seafood lovers.
Step 6: Bake to Perfection
Preheat your oven to 350°F (175°C). Transfer the combined macaroni and cheese into a greased baking dish. For an extra touch, sprinkle additional cheese or breadcrumbs on top. Bake in the preheated oven for about 25–30 minutes, or until the dish is bubbling and the top layer is golden brown. The delightful aroma will fill your kitchen as your Lobster, Crab, and Shrimp Macaroni and Cheese is ready to serve.

Storage Tips for Lobster, Crab, and Shrimp Macaroni and Cheese
Fridge: Store leftovers in an airtight container in the refrigerator for up to 3 days to maintain freshness and flavor.
Freezer: This dish can be frozen for up to 2 months. Let it cool completely before transferring to a freezer-safe container.
Reheating: Reheat in the oven at 350°F (175°C) until heated through and bubbly, adding a splash of cream or milk to retain creaminess.
Dishing Out: For best texture, reheat gently and avoid high heat, which can cause the seafood in the Lobster, Crab, and Shrimp Macaroni and Cheese to become rubbery.
Make Ahead Options
These Lobster, Crab, and Shrimp Macaroni and Cheese are perfect for busy home cooks looking to save time! You can prepare the creamy cheese sauce and cook the seafood (lobster, crab, and shrimp) up to 24 hours in advance, refrigerating them in separate airtight containers.

To maintain quality, store the macaroni separately from the sauce to prevent it from becoming mushy. With this prep, you’ll enjoy an indulgent meal with minimal effort on busy weeknights!
