You can never go wrong with mac and cheese, especially if it’s slow cooker mac and cheese or jalapeno popper mac and cheese. That being said, lobster mac and cheese is the best I’ve ever had, and it’s easy to make too!

Lobster mac and cheese topped with crispy breadcrumbs.

Mac and cheese is pretty great on its own, but when you add lobster to the mix, you end up with something spectacular. I love to make lobster mac and cheese for special occasions – it’s become a family favorite and my kids always request it on their birthday!

How do you make lobster mac and cheese?

This recipe starts with a base of flour, butter, milk and water which cooks into a thin sauce. Pasta goes into the pot along with seasonings, and everything simmers together. The next step is to add a generous amount of grated cheese. Finally, the lobster is added into the mix. The mac and cheese is transferred to a baking dish, topped with breadcrumbs, then bakes until golden brown. Add a sprinkle of chives and dinner is served!

How do you cook lobster?

I like to broil lobster tails to get my chopped lobster meat for this recipe.  The tails can be brushed with butter and sprinkled with salt and pepper, then broiled for about 12 minutes until the meat is opaque. There are many varieties of lobster, and it doesn’t really matter which one you use in this dish. Need more guidance? Check out my complete guide on how to cook a lobster.

How do you reheat lobster mac and cheese?

Mac and cheese tends to thicken up when it’s cooled. I recommend reheating this dish in a low heat oven (about 300 degrees) for 20 minutes or until warmed through.

Cheddar cheese is my favorite choice for macaroni and cheese. It’s flavorful, melts great and gives the mac and cheese its traditional orange color. That being said, make sure you’re using a regular mild, medium or sharp cheddar cheese and not a cheddar cheese that’s extra sharp or aged. The aged cheeses can separate when melted and you won’t get a smooth and silky sauce. For this recipe, I’ve also added some mozzarella cheese because I love the creamy flavor it adds to this dish.

Can you freeze lobster mac and cheese?

I wouldn’t recommend freezing this dish because dairy typically does not freeze well, and can separate and curdle upon thawing.

Lobster macaroni and cheese variations

While I typically prepare this recipe as written, sometimes I use different ingredients for a whole new flavor.

  • Protein: I turn this into seafood mac and cheese by using a combination of shrimp, lobster and lump crab meat.
  • Cheeses: While cheddar is classic in mac and cheese, you can also use fontina, Monterey Jack or even a soft cheese like a garlic and herb Boursin.
  • Herbs: I love the flavor of the chives in this dish, but you can also use parsley, green onions, or even fresh chopped dill.

Once you try this dish, you’ll never look at macaroni and cheese the same way again! The sweet lobster meat pairs perfectly with the creamy pasta and the crunchy breadcrumb topping is the perfect finish.

  1. This recipe is so wonderful. The only alteration I made was to add about 4oz of bacon into the mix, I followed everything else to the T. So decadent and flavorful! <3

    We couldn’t stop eating this amazing dish! Can’t wait to make it again! Loved that it was also easy to make.

    I made this last night for an unconventional Christmas dinner and it was absolutely delicious! I followed the instructions exactly as written, except I used 2% milk because that’s what I had. I will definitely be sharing and saving this recipe to use again. Thank you!!

    P. S. I recommend using the 3-quart dish – mine was full nearly to the top, so I don’t think my 2-quart dish could have handled all the gooey deliciousness!

  4. Hi,
    I need to use GF pasta. Would I still prepare it the same way. Also, can I boil the lobster tails instead of broiling?
