Hey there! This is Heather from Totally Tailgates! Jenny invited me over to share with you one of family’s favorite “company is coming” casseroles. I am thrilled to be here at The Melrose Family to tell you how incredibly easy it is to wow your friends with a decadent lobster mac a cheese casserole!

Not every day is game day, and at Totally Tailgates we enjoy sharing incredible meals with our family and friends all year long. When company is headed to our home, I almost always lean towards a casserole as the centerpiece entree. Casseroles are so very versatile and usually a fairly economical way to serve a crowd. Pair a good casserole with a fresh salad, hot bread, and iced tea and you have a full dinner!

Lobster mac and cheese is one of those meals your friends & family will think you spent hours in the kitchen in preparing. And, it just sounds expensive, right? Wrong.! This recipe is easy to prepare and more budget friendly than one would expect!

Lobster Mac & Cheese Ingredients

  • One Lobster tail 
  • Cheese: Parmesan, cheddar, and Gruyere
  • Butter
  • Flour – used to as a thickener
  • Salt and pepper
  • Whole milk
  • Cayenne Pepper

Let’s get the game started! Your main players on the field are frozen lobster tails and six cups cooked macaroni. I purchased this pack of lobster tails at Wal-Mart for around $12. Only one is used in lobster mac and cheese, so I spent about $4 on a delectable piece of seafood for the whole casserole. ๐Ÿ™‚ I baked the other two tails, and used them for salads….we love suppertime salads on hectic school days or hot summer nights.

Tips For Making Lobster Mac And Cheese

  • Have noodles already cooked for easier prep. To keep the pasta from sticking together after if has been cooked, add a little olive oil to the macaroni and stir it together.
  • You only need one lobster tail for this recipe, but I like to bake a few lobster tails and use the others for weeknight meals.
  • Use whatever Parmesan you have on hand… even the cheap bottled stuff will work.
  • Whole milk works best. Low fat milk will not give you the best results and will leave you with a thinner and less creamy cheese sauce.

How To Make Lobster Mac And Cheese

Step 1: Macaroni

Cook six cups of macaroni drain, and set aside.

Step 2: Get Your Cheeses Ready 

Get your three cheeses ready: cheddar, Gruyere, and Parmesan. I know you are wondering if I actually used powdery Parmesan from that green bottle that our mama’s all used and the answer is yes…yes, I did! Feel free to use freshly grated Parmesan cheese if you wish. It will taste wonderful either way. I used what I had on hand, just like my mama used to do! Gruyere is a little on the pricier side, the canned Parmesan helps keep your budget on track, too.

Step 3: How To Cook Lobster Tails

Spray a glass baking dish with non-stick cooking spray, and place thawed lobster tails in the dish. I dotted the meat in the tails with tiny pats of butter, which is totally optional. I never miss a chance to introduce seafood to butter, so I was literally on autopilot during the preparation phase! Cook until the shell of the tail is a pretty shade of red or reaches an internal temperature of about 135 degrees.

Coarsely chop Mr. Lobster, and set aside. We’ll come back to him in a sec…..

Step 4: How To Make The Cheese Sauce For Lobster Mac & Cheese

Meanwhile, you will make a roux which serves as the basis for the cheese sauce. A roux is simply a reduction of butter and flour which is blended over heat until thickened.

So, melt the butter, whisk in the flour and then the milk. You’ll want to stir the mixture continuously until it is thick and bubbly. This takes a while, so if you are stirring and wondering “how long does Heather think this is going to take?!?” just keep stirring. I’m with ya.

After the mixture is bubbly (and your home is smelling great), and the Parmesan and spices. Voila! A homemade cheese sauce!

Step 5: Preparing The Lobster Mac & Cheese

Now, we are in the homestretch! Gently fold the prepared macaroni noodles into the cheese sauce.

Now, it is time to get back to Mr. Lobster! First, spray a casserole dish with non-stick spray. Add a layer of noodles with the cheese sauce, and top with the lobster meat. Add shredded cheddar and Gruyere cheeses. Bake until hot and bubbly! For an authentic and coastal meal, pair your lobster mac and cheese with some Southern Style Hushpuppies!

Side note: This recipe makes 6-8 servings and since I am an empty-nester now, I made three smaller portions for two. So, if the photo on the left looks like a small portion, well it actually is smaller! You can also prepare lobster mac and cheese in a larger 9×13 baking dish. If you have left overs, you can make Country Fair Style Fried Mac & Cheese Bites using this lobster mac and cheese recipe….they are SO good!
