Step‑by‑Step Instructions for Lobster, Crab, and Shrimp Macaroni and Cheese
Step 1: Cook the macaroni
Start by bringing a large pot of salted water to a boil. Add in the elbow macaroni and cook for about 7-8 minutes until al dente, stirring occasionally to prevent sticking. Once cooked, drain the pasta and set it aside, allowing it to cool slightly while you prepare the rest of the dish.
Step 2: Prepare the seafood
In a large skillet, melt 2 tablespoons of butter over medium heat. Add the peeled and deveined shrimp, sautéing for about 3-4 minutes until they turn pink and opaque. Then gently fold in the lobster and crab meat, stirring to warm through for another 2-3 minutes, and set aside, ensuring the seafood remains tender and juicy.
Step 3: Make the cheese sauce
In a separate saucepan, melt 4 tablespoons of butter over medium-low heat. Gradually whisk in 1/4 cup of all-purpose flour to form a roux, cooking for about 2 minutes until bubbly but not browned. Slowly pour in 2 cups of heavy cream while continuously whisking, cooking until thickened, about 5-7 minutes, then stir in the grated cheddar and Monterey Jack cheeses until melted and smooth.
Step 4: Combine ingredients
Once the cheese sauce is creamy and velvety, add the cooked elbow macaroni and the sautéed seafood mixture to the saucepan. Gently fold everything together until the macaroni and seafood are fully coated in the luxurious cheese sauce, making sure to distribute the flavors evenly.
Step 5: Bake
Preheat your oven to 350°F (175°C) and grease a large baking dish. Transfer the lobster, crab, and shrimp macaroni and cheese mix into the dish, smoothing out the top. If desired, sprinkle additional cheese and breadcrumbs over the surface for a delightful crust. Bake in the oven for 25-30 minutes until golden and bubbly, and the top is beautifully crispy.
