Description

A luxurious yet approachable Lobster Thermidor Gruyère Bake featuring tender lobster, a creamy wine-infused sauce, and a golden Gruyère topping—perfect for special occasions or elevated weeknight dinners.


Ingredients

Scale
  • 2 lobster tails or whole lobsters
  • 3 tablespoons unsalted butter
  • 1 shallot, finely chopped
  • 120 ml dry white wine
  • 1/2 cup heavy cream
  • 1 tablespoon Dijon mustard
  • 2 teaspoons brandy or cognac
  • 2 egg yolks
  • 1/2 cup grated Gruyère cheese
  • 1 tablespoon chopped parsley
  • Salt and pepper to taste
  • Paprika for garnish

Instructions

  1. Boil lobster tails for 6–8 minutes (or whole lobsters for 12–15) until shells turn red and meat is opaque. Cool slightly, then extract and chop meat.
  2. Melt butter in a skillet and sauté chopped shallot for 2–3 minutes until softened.
  3. Add white wine and simmer 2–3 minutes to reduce by half.
  4. Stir in heavy cream and Dijon mustard. Simmer 4–5 minutes until slightly thickened, then remove from heat.
  5. Whisk in brandy and egg yolks until smooth. Fold in lobster meat and season with salt and pepper.
  6. Spoon mixture into reserved lobster shells or a small baking dish. Top with grated Gruyère.
  7. Bake at 200°C (392°F) for 10–15 minutes until cheese is golden and bubbling. Garnish with parsley and paprika.

Notes

Use Emmental as a mild cheese substitute. Avoid overcooking lobster for the best texture. Reheat gently to maintain sauce creaminess.
