Folks legit can’t get over how good my Lobster Mac and Cheese recipe is. The rave reviews speak for themselves. My trick is using a mix of different cheeses so you get a lot of meltiness and creaminess. Then I spice the heck out of that cheese sauce y’all. Add in the lobster and a crunchy topping of buttery bread crumbs, and this dish just hits hard. I serve it for any special occasion where I need to straight up impress folks.

How To Make Lobster Mac and Cheese

Step 1: Cut lobster tails in half vertically and place on a foil lined baking sheet. Melt 2 tablespoons of butter and brush the tops of lobster tails with butter then sprinkle with cajun seasoning. Bake for 10 minutes at 450 or until they develop a beautiful color then remove from shells. Roughly chop lobster into large chunks in a medium sized bowl and pour remaining butter from the baking sheet over the lobster and set aside. Lower temperature on oven to 375 degrees.

Step 2: Add olive oil to pan and heat over medium high heat. Add garlic and cook for 1 minute then add 3 more tablespoons of butter to the pan and allow to melt down.
TIP: When your tails come out of the oven the meat should be firm and only very slightly opaque. Remember, the meat will continue to cook while resting.

Step 3: Quickly whisk in flour and cook for approximately 1 minute.

Step 4: Pour in heavy cream and whole milk continuing to whisk. Next add onion powder , garlic powder, dry mustard, paprika and cayenne continuing to whisk. Season with salt and pepper.

Step 5: Stir in half of shredded cheeses and allow them to melt continuing to stir. Once cheese melts down, turn off heat.

Step 6: Stir in beaten eggs and 1 tablespoon of butter into the pasta.

Step 7: Next pour as much of the cheese sauce as you would like (for super cheesy, use it all) and half of the lobster to the pasta and mix super well.

Step 8: Next spread remaining lobster over top of mac and cheese. Top with remaining shredded cheeses leaving the lobster pieces bare so they will be seen once baked. P.S. Add extra shredded cheese to the top of this dish if you want it to be super cheesy and have all the cheese pulls.

Step 9: Finally in a small bowl, melt remaining 2 tablespoons of butter and add breadcrumbs and toss together.

Step 10: Sprinkle breadcrumbs over the top leaving the lobster mostly bare so it peeks through and bake at 375 for 27-35 minutes. Rest before serving.

Recipe Tips
- Cook the Pasta to Al Dente: Remember, it will continue cooking in the oven with the cheese sauce. Don’t overcook it because it will end up mushy.
- Avoid Overcooking the Lobster: They will continue to cook in the oven once mixed into the mac and cheese, so slightly undercooking them will keep them from being rubbery.
- Choose Fresh Lobster: Whenever possible, opt for fresh lobster. The freshness will shine in this mac. In fact, ask your local market attendant at the seafood counter to pull the good stash from the back.
- Let it Rest Before Serving: This allows the cheeses to set a bit.
- For the roux. Use room-temperature milk to avoid seizing and clumping.
- Taste as you go! Seasoning is always based on preference. A little extra paprika or garlic never hurt nobody.
- Don’t use pre-shredded cheese. They use an anti-caking agent to keep the cheese from sticking together so it doesn’t melt as well. Instead, buy in blocks and shred them yourself.

I made this for Fathers’s day….along with the Balsamic Brown Sugar Lamb Chops and the Peach Cobbler Cheesecake…..wow, wow, wow! I had never cooked lobster before, and had to do a quick google/pinterest search to figure out to butterfly the tails, but it’s easy enough once you figure it out. Honestly, the mac and cheese by itself was heavenly, but the addition of the lobster takes it to the next level. This is for sure going to be remade time and time again in my kitchen! I’m actually a bit sad I offered to share some with a friend….there’s less leftovers for me to enjoy! 😉
This is amazing. You have to make it.
Good morning, this dish looks so good I’m salivating. Could you upload a video? I’m a visual learner so that’d help me out a lot.
