Ingredients
  

Lobster and Sauce Base
  • 2 whole whole lobsters Alternatively, use cooked lobster meat.
  • 2 tablespoons butter For creating a creamy sauce.
  • 2 tablespoons flour To thicken the sauce.
  • 1 cup milk or half and half For a rich sauce.
  • 1 tablespoon Dijon mustard Adds a unique flavor.
  • 1 cup Parmesan or Gruyere cheese For browning on top.
  • 1 tablespoon lemon juice To brighten the dish.

Method
 

Preparation
  1. Begin by cooking or steaming the lobsters until bright red and the meat is opaque.
  2. Allow the lobsters to cool, then remove the meat from the shells.
  3. In a saucepan, melt the butter over medium heat, then whisk in the flour to create a roux.
  4. Slowly add the milk or half and half while continuously whisking until the mixture is smooth and thickened.
  5. Stir in the Dijon mustard and lemon juice, seasoning with salt and pepper to taste.
Combining
  1. Fold the cooked lobster meat into the creamy sauce until well combined.
  2. Transfer the lobster and sauce mixture to a shallow baking dish.
  3. Top with grated cheese evenly.
Baking
  1. Preheat the oven to 375°F (190°C) and bake the lobster for about 20-25 minutes until the sauce is hot and bubbling.
  2. Broil for an additional 2-3 minutes to achieve a golden top, watching closely to prevent burning.
Serving
  1. Let the dish rest for about 5 minutes before serving.
  2. Enjoy with crusty bread or a simple green salad.

Notes

This dish can be prepared ahead of time by combining the lobster and sauce and keeping it covered in the fridge for up to a day. Bake when ready and add the cheese topping right before cooking.
