  • First, cook the pasta. We like to use cavatappi pasta or elbow macaroni for this recipe, but you can use any type of pasta. Penne, rigatoni and farfalle are other popular options.
  • Next, prepare the sauce. Add the butter to the skillet on medium heat. Whisk in flour and cook for another minute. Whisk in the milk until combined. Make sure the mixture does not form any lumps. Season with salt, pepper and nutmeg. Simmer for about 2 to 3 minutes, until the mixture thickens slightly. Remove the pan from the heat and stir in the cheeses.
  • Stir the cooked pasta into the sauce and transfer to a 9×13 baking dish. Top with more cheese and Panko breadcrumb topping. Bake and enjoy!

  1. Where do I add the lobster here? Don’t see it on coming instructions.

    • Hi Tiffany! I’m not exactly sure what you mean as the recipe includes the lobster in the ingredient list and directions. You add the cooked lobster during step 4 (with the pasta.) Enjoy!

  2. I first love this recipe because it’s easy and delicious and also love that it is jazzed up with the lobster! Checks all the boxes to a perfect dish!

  3. Made this for a potluck and it was a hit!
