What you need to make the Langostino Lobster Mac and Cheese

To make the Baked langostino mac and cheese recipe, you will need:

  • Conchiglie/shell pasta. It holds the sauce really well!
  • Half and half and milk. 2% or whole milk, whichever you prefer.
  • Cream cheese and brie.
  • White cheddar. Hand grated is best.
  • Grated parmesan cheese.
  • Butter, for the roux, and for sautéing the lobster tails.  
  • All-purpose flour.
  • Fresh grated nutmeg. So much better than the pre-ground stuff!
  • Lemon zest and minced garlic.
  • Salt and pepper to taste. Always.
  • Frozen Langostino lobster tails, fully thawed.
  • A little cornstarch slurry (equal parts cornstarch and water).

Prepping the ingredients for the Langostino Mac

To make the mac and cheese super easy to assemble, prepping first is key. I like to boil my noodles to al dente first, so they are ready to go when the sauce is ready. You’ll also want to leave the cream cheese and brie out on the counter to soften, so it easily incorporates into the sauce. And I highly recommend grating your own cheddar for a creamier result. You’ll also want to thaw your Langostinos overnight in the fridge so they are ready to sauté.

With everything prepped and at the ready, making the sauce and cooking the Langostinos is a breeze!

Topping and baking the Baked Langostino tails mac and cheese recipe

Once your sauce is ready and your noodles are well coated, they’ll get transferred to a greased baking dish. You can grease the dish with either more butter, or cooking spray.

To finish, you’ll cook up the Langostino tails in a bit of butter and lemon zest briefly, until they are just warmed through. Once warmed, they tails get folded into the mac and cheese and spread on top. For even more seafood goodness, you’ll make a quick little sauce out of the reserved liquid from cooking the Langostino lobster tails with a cornstarch slurry. The sauce thickens in mere minutes, and is then poured right over the mac and cheese mixture.

Last but not least, the creamy concoction is topped with a layer of grated parmesan. Then it’s off to the oven to bake for 25-30 minutes, until browned, bubbly and delicious!
