Step‑by‑Step Instructions for Lobster, Crab, and Shrimp Macaroni
Step 1: Cook the Pasta
Begin by boiling a large pot of salted water. Once it reaches a rolling boil, add the elbow macaroni and cook according to package instructions until al dente, about 7-9 minutes. Drain the macaroni in a colander and set it aside, allowing any excess moisture to escape.
Step 2: Prepare the Roux
In a large saucepan, melt 4 tablespoons of butter over medium heat. Once fully melted, sprinkle in ¼ cup of all-purpose flour, whisking continuously for about 2-3 minutes until the mixture is smooth and begins to bubble, creating a roux. The roux should be lightly golden, signaling it’s ready for the next step.
Step 3: Make the Cheese Sauce
Gradually whisk in 2 cups of whole milk into the roux, stirring constantly for 5-7 minutes until the mixture thickens and coats the back of a spoon. You’re aiming for a creamy sauce; once thickened, lower the heat and add 1 cup of grated cheddar and 1 cup of Gruyère cheese, stirring until melted and smooth.
Step 4: Combine Seafood and Pasta
Gently fold in the reserved elbow macaroni along with 1 cup of cooked lobster meat, 1 cup of lump crab meat, and 1 cup of cooked, deveined shrimp into the cheese sauce. Stir carefully until each piece of seafood is coated in the rich, creamy sauce, ensuring even distribution throughout.
Step 5: Transfer and Top
Preheat your oven to 350°F (175°C). Transfer the seafood macaroni mixture into a greased 9×13-inch baking dish, spreading it evenly. Sprinkle a generous layer of breadcrumbs over the top, which should be about ½ to 1 cup for that perfect crunchy finish.
Step 6: Bake to Perfection
Place the baking dish in the preheated oven and bake for approximately 25-30 minutes, or until the top is golden brown and bubbly. Keep an eye on it during the last few minutes to prevent over-browning; if needed, cover loosely with foil.
Step 7: Cool and Serve
Once baked, remove the Lobster, Crab, and Shrimp Macaroni from the oven and allow it to cool for about 5-10 minutes. This resting time improves the texture and makes serving easier. Dish it up warm and relish each decadent bite of this luxurious comfort food!
