Lobster Mac and Cheese

I’m craving all the comfort foods and this Lobster Mac and Cheese recipe is at the top of my list. I bought one a few weeks ago at the farmer’s market and it was truly lacking in creamy, cheesy comfort so I knew I had to make my own. Homemade mac and cheese is always better anyway.

But this is the BEST Lobster Mac and Cheese recipe ever made and it’s soooooo easy to prepare. I can have this on the table in just under an hour. BUT bonus points because this recipe can be prepped in advance and then baked in the oven right before serving making this a great dinner for holidays….or how about just a Monday night.

How to Make Lobster Mac and Cheese

You’re going to be so seriously surprised at how easy this Lobster Mac N Cheese is to make from scratch. You can even prep the whole recipe in advance and then just bake it right before serving making this the ultimate recipe for entertaining.

  1. Add pasta to boiling water and cook until just al dente (the pasta will still be firm but not crunchy).
  2. Drain pasta and set aside. In a large pot over medium-low heat, melt the butter.
  3. Sprinkle the flour over the butter, whisking to combine and make a roux. (It will look like a paste.) Continue cooking, stirring constantly with a wooden spoon, until the roux is golden brown.
  4. Slowly add the milk and cream, whisking constantly to incorporate and create a béchamel sauce. Stir in the nutmeg. Increase the heat to medium-high and bring the sauce to a low boil, whisking constantly.
  5. Reduce to a simmer, whisking occasionally, and cook until the béchamel sauce is thick and coats the back of a spoon, about 4-5 minutes.
  6. Stir in the salt, pepper, and mustard powder. Add the cheeses, 1 cup at a time, whisking until each addition is completely melted before adding more. Remove from heat.
  7. Stir the drained pasta into the sauce and toss to coat.
  8. Fold in the lobster meat.
  9. Transfer macaroni mixture to the prepared baking dish and place on a rimmed baking sheet covered with foil.
  10. Sprinkle topping evenly over pasta. Bake until golden and bubbling, approximately 20-25 minutes.
  11. Allow to cool 15 minutes before serving.

Seriously……so easy. Don’t you think?

Alternatively, you can FREEZE your Lobster Mac & Cheese recipe for up to 2 months. Cover tightly with plastic wrap and then with two layers of aluminum foil before freezing.

To bake your previously frozen Lobster Mac and Cheese, uncover and bake at 400 degrees for approximately 60 minutes or until heated through and bubbling.

What is the best cheese for mac and cheese?

You can use whatever cheese you like for mac and cheese, I like to tinker with my mac and cheese recipes to try out different combinations of cheese but for this Lobster Mac and Cheese recipe, I like to use a blend of cheddar and gruyere because of the sharpness of both cheeses. The meltability of the cheddar and gruyere is far superior to many other cheeses, as well, making it perfect for baked mac and cheese recipes.

What cheese is similar to Gruyere?

Gruyere cheese is a mild form of swiss cheese that’s easy to find at many supermarkets, however, if you are having trouble finding Gruyere specifically you can use a standard swiss cheese in it’s place. Jarlsberg is a great swiss cheese that would work well in this Lobster Mac and cheese recipe.

In my opinion, this is the BEST Lobster Mac and Cheese ever because the sauce is smooth and creamy….very similar to Ruth’s Chris Mac and Cheese or the same one we’ve enjoyed at the Capital Grille. It’s the perfect steakhouse side dish but we love to enjoy it as a main course with a salad, too.
