Lobster Mac and Cheese is a classic spin that elevates mac and cheese to an entirely different level. We’ve been meaning to get around to writing this recipe for our customers and have finally got to it!
We’ve already gone over some simple recipes like butter poached lobster, as well as some classic recipes like lobster bisque and lobster ravioli. Now that we’re moving into spring months and the covid-19 pandemic is starting to come to an end, family gatherings and potlucks are going to go next level! Lobster Mac and Cheese is a great way to prepare lobster for many guests, but also just a great meal to prepare for yourself or the family.
With all that being said, let’s get started on the lobster mac recipe!
Ingredients For the Cheese Sauce for the Lobster Mac and Cheese
- 8 ounces of mascarpone cheese
- 1 Cup for sharp cheddar cheese, shredded
- 3 Cups of fontina cheese
- 3 1/2 Cups of whole milk
- Pinch of cayenne pepper
- 1/4 Cup of all purpose flyer
- 6 tablespoons of butter
Ingredients For the Breadcrumb Topping for the Lobster Mac
- 1-2 teaspoons of lemon zest
- 1 clove of garlic diced
- kosher salt
- 2 tablespoons of butter
- 1 1/2 cups of fresh breadcrumbs
Ingredients For the Pasta for the Lobster Mac and Cheese
- 1 lb of your choice of pasta noodles (elbows, conchiglie, shells, capatappi for example)
- 1 lb of cooked lobster meat
- You can use our pre-cooked lobster meat or frozen lobster tails (see post on how to cook lobster tails)
- Chopped parsley for garnish

Let’s get things started for the Lobster Mac and Cheese
The most important step is getting yourself organized. There are a lot of components to the lobster mac and cheese dish but cooking them is easy.
- We’ll start by getting the oven pre-heated to 350 degrees Fahrenheit.
- Get water boiling on the stove and cook the pasta al dente as the package specifies. Drain and set aside while we prepare the rest of the components for the dish.
Cooking the Lobster Tails for the Lobster Mac and Cheese
As linked in the ingredients, you can use our cooked lobster meat but we also have great deals on lobster tails for sale that can really elevate this dish to a whole new level. We’ll go over some quick instructions on how to steam the lobster tails for the lobster mac and cheese.
- Pour about an inch of water in a large pot and bring to a boil
- Add a tablespoon of salt and place the steamer insert inside the pot so that it is just above water level
- Put the lobster tails on the rack and cover the pot
- Cover and steam for about a minute to a minute and a half per ounce of lobster tail sizes (ie.8 minutes per 6oz tail)
- Set aside and let cool while preparing the cheese sauce (tip, the lobster will continue cooking so you can either shock with cold water, or slightly undercook and allow it to cook through while it rests)
Preparing the Cheese Sauce for the Lobster Mac and Cheese
- Melt about 4 tablespoons of butter in a large saucepan over medium heat
- Whisk in flour to make a nice roux, and add in a pinch of cayenne pepper.
- Cook over medium-low heat for about 3-4 minutes until the roux becomes light brown in color
- Whisk in the milk and cook over medium heat for another 5 minutes until the sauce begins to thicken. Whisk frequently.
- Bring the heat down to low for about 10 minutes.
- Once the sauce has thickened, remove from heat and stir in the mascarpone until melted. Add in the fontina and cheddar cheese, and stir until melted in the sauce. If the cheese isn’t melting, turn the burner on low and stir until the sauce becomes smooth.
Prepare your breadcrumb topping for the Lobster Mac and Cheese
- Melt 2 tablespoons in a small frying pan over medium-high heat
- Add in the finely chopped garlic until it has a nice fragrance
- Add in the breadcrumbs and turn the heat to high to toast for about 1 minute.
- Stir in the lemon zest and season to taste with salt, then remove from heat.
Finishing up your Lobster Mac and Cheese
- Dice your cooled lobster into bite-sized pieces (remove from shell if using lobster tails).
- Stir in your drained pasta to the cheese sauce to thoroughly coat, and gently add in your lobster meat.
- Spoon pasta into one baking dish or multiple one-serving gratin dishes.
- Sprinkle bread crumb mixture on top of the pasta and bake for 15-20 minutes or until the lobster mac and cheese is bubbly and light-brown on top.
