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!

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!

If you are in the mood for lobster, try some other great lobster dinner recipes like lobster salad, grilled lobster tail, lobster rolls and my very popular seafood boil that features, you guessed it, lobster!

Lobster Mac And Cheese Ingredients

To make this delicious mac and cheese you will need butter, all purpose flour, water, milk, pasta, salt, cheddar cheese, mozzarella cheese, lobster meat, panko breadcrumbs, chives and seasonings.

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 the shredded cheeses. Finally, add the lobster into the mix. Transfer the mac and cheese to a baking dish, top it with breadcrumbs, then bake it until golden brown. Add a sprinkle of chives and dinner is served!

Tips For Lobster Mac And Cheese

  • I recommend shredding your own cheese. The pre-shredded bags of cheese can have anti caking agents that prevent the cheese from melting well.
  • Leftovers of this dish will stay fresh in an airtight container in the fridge for three days. I do not recommend freezing this dish because it will not freeze well.
  • You can use other short pastas. Simply adjust the cooking time to the amount of time stated in the package instructions. If you use a larger pasta you may need to add more milk.

Quick Tip

Make sure you have cooked and chopped lobster meat before you start this recipe. The lobster can be chilled before it goes into the mac and cheese.

Recipe FAQs

How do you reheat lobster mac and cheese?

I recommend reheating lobster mac and cheese in a low heat oven (about 300 degrees) for 20 minutes or until warmed through.

What is the best cheese to use for macaroni and cheese?

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. Make sure to use a mild, medium or sharp cheddar cheese and not an extra sharp or aged cheddar cheese. 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.

Why is lobster mac and cheese a thing?

Lobster mac and cheese is popular because it takes the comfort food classic dish of mac and cheese and adds the decadence of fresh chunks of sweet lobster meat. You can’t go wrong with combining these two great flavors.

How do you cook lobster?

I like to broil lobster tails to get my chopped lobster meat for lobster mac and cheese. Brush the tails with butter and sprinkle them with salt and pepper, then broil them 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.

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 and lobster. I also have an amazing crab mac and cheese recipe.
  • 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.

    My husband (who is allergic to shellfish) made this for me for my birthday a few years back. I loved it so much, I use this recipe as my go to Mac and Cheese and just omit the seafood. I play with the cheese mix here and there but this recipe is delicious as is (with or without lobster)!

    1. It should just take about 2-3 minutes, it’s not supposed to be super thick at that point because the starch from the pasta will also thicken the sauce later.

  2. 5 stars
    Delicious. Made it with just cheddar cheese, other than that, followed the recipe .Cut it in half and my wife and I still got two nights out of it. Going to try it with shrimp next time.

    1. You can make it ahead but just be aware the pasta will continue to absorb the sauce as it sits, so it might be a bit drier as a result.

  3. 5 stars
    This was a HUGE HIT! We made this for part of our Christmas dinner and it was the favourite thing we had. I added sauteed onions and garlic and some dry mustard. Plus, since we were treating ourselves because we were home alone during the pandemic, I added crab legs and a can of crab. OUTSTANDING! I will use this as my basis for making mac & cheese in the future (without going overboard on the seafood). We do have leftovers but – not for long! Thank you for a wonderful recipe! I am sending it off to my relatives today so they know what they missed at our house.

    1. What is it with dried mustard and Mac and cheese. Always better ! This is a great recipe and the idea of making it while cooking the pasta is genius!

      1. Does using individual baking dishes alter this recipe? Also can you substitute seafood stock for the water?

      2. Individual dishes should be fine. You can use seafood stock but then you’ll need to reduce the amount of salt you add to the recipe!

    Substituted gluten free pasta and almond flour and adjusted the cook time by a few minutes….WOW! Outstanding dish, thank you for sharing this recipe!

  5. 5 stars
    Delicious! I love your time (and dirty pan) saving process of cooking the dry pasta with the sauce. For the water, I used the water I boiled the lobster tails in to get even more lobster flavor throughout. this recipe is definitely a keeper. Thanks!

  6. 5 stars
    Very good!! I played around with the seasonings and cheeses based on our taste preferences. This is so easy and the method is awesome. Thank you!

      We are not “mac n cheese” lovers… but I’ve always heard a lot of people talk and order, ‘ lobster mac n cheese’ , I was also looking for a different side dish to make with our lobster tails. So I decided to give it a try. I am BEYOND happy I tried this recipe – it was great tasting, easy to do and easy to follow instructions. So thank you for this great recipe! To anyone reading the reviews to see if this recipe is worth trying??? LOOK NO FURTHER!!
      I loved the automatic option of changing serving size…. BUT 🙁 the adjusted measurements were a little hard to follow.

      1. 5 stars
        Delish, I had to go one it several around the noodle cooking; have never seen them cooked as you do it before, But liked that step saver. Turned out excellently. I also added some chopped cooked bacon, which luckily did not detract from the lobster. Little in the way of leftovers speaks volumes…perhaps a small lunch left!

  7. This is amazing !!! We tried Mac and cheese the first time at a restaurant…this was far better !!!! Thank you

  8. so I want to make this tomorrow, if I can’t;t find fresh lobster can I use frozen lobster or imitation?
    Thanks in advance.

  9. I never did eat mac & cheese, but I tried it with the lobster. Now, I LOVE LOBSTER MAC & CHEESE. I am gonna try this recipe, I just know I am gonna like it. I think I am gonna join a gym also, asI know I am gonna make this dish more than I should. Thanks…

    1. I’ve been eyeing to make this recipe for so long and i’m finally gonna try to make it tomorrow. I’m so excited! Although i don’t think we’ll be able to finish it but ‘ll store it in our refrigerator so we can consume it at a later date. How long is the shelf life of this mac and cheese? Thank you!
