Herm Island Lobster Thermidor

Ingredients

  • 2 live lobsters (about 1 1/2 pounds each)
  • 1/2 cup unsalted butter
  • 1/4 cup all-purpose flour
  • 1 1/2 cups whole milk
  • 1/2 cup grated Gruyère cheese
  • 1/4 cup grated Parmesan cheese
  • 2 tablespoons Dijon mustard
  • 1/4 cup chopped fresh parsley
  • Salt and pepper to taste

Instructions

  1. Bring a large pot of salted water to a boil. Add the live lobsters and cook for 8-10 minutes until they turn bright red. Remove from the pot and let them cool.
  2. Once the lobsters are cool enough to handle, crack the shells and remove the meat. Chop the lobster meat into bite-sized pieces and set aside.
  3. In a saucepan, melt the butter over medium heat. Whisk in the flour to create a roux, then slowly pour in the milk while whisking constantly. Cook until the sauce thickens, then stir in the Gruyère cheese, Parmesan cheese, and Dijon mustard. Season with salt and pepper.
  4. Add the chopped lobster meat and parsley to the sauce, stirring to combine. Simmer for a few minutes until the lobster is heated through.
  5. Preheat the broiler. Transfer the lobster mixture to a baking dish and sprinkle with additional Parmesan cheese. Place under the broiler for 3-5 minutes until the top is golden and bubbly.
  6. Serve the Herm Island Lobster Thermidor hot, garnished with fresh parsley.
