What Kind Of Lobster Do I Use?

For this lobster mac and cheese recipe, you want about 1 and 1/4 pounds of lobster meat. I think freshly steamed lobster tails are the best choice and you’d need 2 – 3 of them.

You can take a shortcut and use frozen lobster meat for this macaroni and cheese, but fresh is better if you have access to it. If you’re not into steaming your own lobster, many grocery stores will steam one for you while you wait.

How To Make Lobster Macaroni And Cheese

To start, get your oven preheating and your water for the pasta boiling. Then, you’ll make a rich cheese sauce with sharp Cheddar and Gruyere cheese. Gruyere is a great melting cheese – it’s traditionally used for fondue – and its nutty flavor pairs wonderfully with buttery lobster.

To make the cheese sauce, you’ll start by making a roux of butter and flour. Then you’ll add milk, minced shallot, ground mustard, and nutmeg. Let that simmer until it starts to thicken, around 5 to 10 minutes.

Next, add in all that delicious cheese. You’ll want to stir it until it’s mixed in and smooth. Mix your cooked macaroni noodles with the amazing cheese sauce and then stir in the cooked and chopped lobster.

All of that gets put in a baking dish, then sprinkle with buttery breadcrumbs. Put the lobster mac and cheese into the oven and bake uncovered until the cheese is bubbling and the crumb topping is browned. It’s sooo good!
