How to Make Lobster Thermidor in Casserole
-
Boil the Lobsters: Bring a large pot of salted water to a boil. Add the lobster tails and cook for 8-10 minutes until they turn bright red. Once done, remove them and let cool slightly.
-
Extract the Meat: Once the lobsters are cool enough to handle, carefully extract the meat from the tails and claws. Chop them into bite-sized pieces and set aside for later.
-
Make the Roux: In a saucepan, melt the butter over medium heat. Add the chopped shallots and cook until they become translucent, about 3-4 minutes. Sprinkle in a bit of flour, stirring to form a roux. Cook for 2 minutes to eliminate the raw flour taste.

Create the Sauce: Gradually pour in the fish stock and heavy cream while constantly whisking to prevent lumps. Cook until the mixture thickens slightly, about 5 minutes.

Combine Ingredients: Stir in the chopped lobster meat, Dijon mustard, and a splash of brandy. Mix until everything is well combined and heated through, about 3-4 minutes.
-
Prep for Baking: Preheat your oven to 200°C (about 400°F). While the oven heats, fill individual casserole dishes with the luscious lobster mixture.
-
Add the Cheese: Generously sprinkle the grated cheese over the lobster mixture in each dish. This will create that irresistible cheesy crust as it bakes.
-
Bake Awesomely: Place the casseroles in the preheated oven and bake for 10-15 minutes, or until the cheese is golden and bubbly.
