How to make Lobster, Crab, and Shrimp Macaroni and Cheese

Step 1: Prepare the oven. Preheat it to 375 degrees F.

Step 2: Using cooking spray, coat a 2-quart baking dish. Alternately, you can lightly coat the baking dish with butter.

Step 3: Following the package directions, cook the pasta until al dente. Drain when done and rinse under cold water. Set aside.


Step 4: In a large pot, melt 6 tbsp butter over medium heat. Once the butter has melted, stir in the flour for about 30 seconds until combined.

Step 5: Gradually stir in the milk and cream, cooking for another minute or so until mixed and smooth. Then, adjust the heat to low.

Cheese Sauce:

Step 6: About a handful at a time, stir in the shredded cheeses into the Roux, stirring in between each addition until completely mixed. To taste, season with salt and pepper. Then, take the cheese sauce off the heat.

To Assemble and Bake the Mac and Cheese:

Step 7: Into the cheese sauce, gently stir in the cooked pasta and seafood mixture.

Step 8: Into the prepared baking dish, pour the mixture.

Step 9: Melt the rest of the 2 tbsp butter and whisk it with the Panko. On top of the Mac & cheese, sprinkle the mixture. Place in the preheated oven and bake for about 30 minutes or until the seafood Mac and cheese is hot and the breadcrumbs are golden brown.

Step 10: Remove from the oven when done and serve the Lobster, Crab, and Shrimp Macaroni and Cheese right away. Enjoy!
