Lobster Mac and Cheese with Bacon Breadcrumbs

This creamy baked lobster mac and cheese recipe includes a homemade cream sauce, buttery bacon breadcrumbs, and tender lobster tail meat.

A generous spoonful of creamy, cheesy lobster mac and cheese, homemade with cavatappi noodles, a rich cheese sauce, and buttery bacon breadcrumbs.

Imagine this: homemade baked mac and cheese with a super creamy, cheesy sauce made from scratch. Sounds good, right? What if we loaded it with lobster tail meat—even better? Okay, okay… what if I layered the lobster mac and cheese with even MORE cheese, then topped it off with butter bacon breadcrumbs? Freaking amazing, right?!

Well, Cousins, that is what I did! I made the best lobster mac and cheese EVER a couple of nights ago. Now I know I must share the recipe with you!

I planned on posting a seafood macaroni and cheese recipe a few years ago. Y’all know I love me some creamy seafood recipes, like my seafood macaroni salad or my seafood baked ziti recipe. A few years back, I went to Margaritaville in Las Vegas and fell in love with their seafood mac and cheese. It was so freaking good I swore up and down that I would recreate it (I even posted about it on my Instagram!). However, I never got around to it.

Fast forward to now. I was grocery shopping a few days ago and decided it was time. So I gathered up all the ingredients to make homemade seafood mac and cheese. However, once I reached the seafood department, I changed my mind. Instead, I decided to make a simple lobster macaroni and cheese. I thought it would be a little easier and, of course, less expensive than making a fully loaded seafood mac and cheese with scallops, crab, shrimp, and lobster (but of course, I still wanted to make it feel dressed up and special).

Once I got home and unpacked all my ingredients, I decided I wanted my baked mac and cheese to have a crisp topping. That’s where the bacon breadcrumbs come in. The rest is history! Now, y’all have a creamy, delicious, homemade from-scratch lobster mac and cheese recipe.

It’s a little boujee, but it’s perfect for a special occasion. Holidays, the occasional date night, just because you’re feelin’ fancy. It’s what I call comfort food at its finest!

What’s in Lobster Mac and Cheese?

This homemade lobster mac and cheese recipe is made with pretty simple ingredients. If you’ve already peeked at the recipe card at the end of this post, it may look like a lot of steps, but I swear it’s actually a pretty easy recipe! The best homemade lobster mac has three main parts:

  • The pasta: A typical mac and cheese is made with elbow macaroni pasta, and if you want to use that kind, it will work just fine. I, however, chose to use cavatappi. The noodles are cute and hang on to a LOT of sauce. The best pasta for mac and cheese has a lot of nooks and crannies to hang onto the creamy, cheesy sauce.
  • The seafood: I use lobster tail meat for my recipe. I chose to use frozen cooked lobster meat, but if you find a deal on fresh lobster, go for it! Lobster meat is sweet and buttery, which goes perfectly with the creaminess of the homemade cheese sauce.
  • The cheese sauce: My homemade cheese sauce is oh-so-creamy! I make it with butter, evaporated milk, half and half (or heavy cream), sour cream, and FOUR types of cheese! I recommend shredding or cubing the cheese off the block. It is so much fresher and creamier than pre-shredded cheese.

How to Make Homemade Lobster Mac and Cheese

Step 1: Make the bacon for the bacon breadcrumb topping.

You want to start by cooking the bacon for our buttery bacon breadcrumb topping. You can either cook the bacon in the oven, like I did or pan-fry it. Either way, you want it nice and crispy. Make sure to reserve some of the bacon grease, which will add tons of flavor to our cheese sauce.

Step 2: Make the creamy cheese sauce.

Our homemade cheese sauce starts with a simple roux—salted butter and all-purpose flour, with some of that savory bacon grease. After the roux is formed, you’ll add the evaporated milk, half and half (you can also use heavy cream if that’s what you have on hand), and sour cream.

At this point, you can add some basic seasonings—salt and pepper, garlic powder, onion powder, or even some cayenne pepper for a kick of heat. It’s up to you and your tastes, but basic salt and pepper are a must!

Finally, once that cream sauce is nice and bubblin’, lower that heat and add in the cheese. I use muenster and smoked gouda as the base for my creamy cheese sauce. You can use your favorite kinds of cheese—mild or sharp cheddar cheese, cheddar jack, Italian cheese, the possibilities are endless! Off-the-block cheese melts so much better than pre-shredded, and for this fancy mac and cheese recipe, it is 100% worth it! After the cheese is mixed in and fully melted, take the cheese sauce off the heat, so it doesn’t overcook.

Step 3: Make the pasta.

This is the easiest step of them all. Simply cook the pasta based on the package directions. For the perfect al dente pasta, cook for 6-7 minutes in boiling, salted water. Once it’s done, drain the pasta (don’t rinse it, and you don’t have to save any pasta water for this recipe), and add it to the cheese sauce.

Note that it will seem like you have a LOT of cheese sauce for the amount of pasta. This is how we want it—we don’t want no dry mac and cheese in this house! So don’t worry; this lobster mac and cheese will be the creamiest, cheesiest, least dry seafood mac and cheese you’ve ever had, baby.

Step 4: Make the buttery bacon breadcrumbs.

For this next step, all you have to do is toss the bacon into a food processor with some breadcrumbs and butter, pulse it up, and you’re good to go. Some tips for the best breadcrumb topping:

  • If you don’t like bacon or don’t eat pork, you can substitute it with turkey bacon. Since turkey bacon renders less fat, you’ll just have to use a little bit of olive oil in the roux instead of bacon fat.
  • Use seasoned breadcrumbs for extra flavor. For example, Italian breadcrumbs would be delicious in this recipe!
  • A blender works just fine if you don’t have a food processor. No blender? No problem. Give your bacon a nice chop into fine pieces, and use melted butter to mix everything together.


Step 5: Get ready to bake the lobster mac and cheese!

The final step—prep and bake! First, add the chunks of lobster meat to the mac and cheese sauce and mix. If you’re using pre-cooked lobster like I am, you don’t want the meat to overcook, so don’t leave it on the stove for too long after adding it to the cheese sauce.

Then, butter a baking dish. Add half of the lobster mac and cheese to the baking dish. At this point, I add more shredded cheese—a hearty lay of Monterey jack and cheddar cheese. Pour the rest of the lobster mac, another layer of cheese, and finally, the buttery bacon breadcrumb mixture.

Pop this babe in the oven at 350 degrees for 20-25 minutes until the top is nice and golden brown and that creamy cheese is bubbling. Y’all. Mouthwatering. Cheesy. Creamy. THE BOMB.

What to Serve with Homemade Lobster Mac and Cheese

This creamy lobster mac is honestly the star of the show. It can absolutely be your entrée! You could serve it alongside steak for a surf and turf dinner if you feel extra fancy. As far as side dishes for lobster mac and cheese, simple is better! Serve with homemade garlic bread or cheesy garlic and herb cornbread. Buttery breadsticks, homemade dinner rolls, or a tossed green salad are simple and allow the lobster mac to take all the attention.
