Ingredients You’ll Need

Before you begin, gather these high-quality ingredients for the best results.

For the Lobster Thermidor:

  • 2 whole lobsters (approximately 1.5 lbs each), split lengthwise
  • 2 tbsp unsalted butter
  • 2 tbsp all-purpose flour
  • 1 cup heavy cream
  • 1/2 cup dry white wine
  • 1 tbsp Dijon mustard
  • 1 tbsp cognac
  • 1/4 tsp ground nutmeg
  • 1 tbsp fresh tarragon, finely chopped
  • 1 tbsp fresh parsley, finely chopped
  • 1/4 cup grated Gruyère cheese
  • 1/4 cup grated Parmesan cheese

For Plating and Garnishes:

  • Saffron beurre blanc (1/4 cup)
  • Microgreens (for garnish)
  • Smoked paprika (a pinch)
  • Citrus pearls (optional, for brightness)
  • Roasted baby vegetables (asparagus and heirloom carrots)


Step 1: Prepare the Lobster

Your lobster is the star of this dish, so handling it properly is essential to achieving that delicate texture and flavor.

Ingredients Used in This Step:
2 whole lobsters, water, and salt (for boiling).

Method:

  1. Boil the Lobster: Bring a large pot of salted water to a boil. Cook the lobsters for 7–8 minutes, then remove them and let them cool slightly.
  2. Extract the Meat: Carefully split the lobster lengthwise. Remove the meat from the tails and claws, dice into bite-sized pieces, and set aside. Reserve the shell halves for plating.

💡 Pro Tip: Use kitchen shears to cut through the shells cleanly for a polished presentation.


Step 2: Make the Thermidor Sauce

The creamy, herbaceous Thermidor sauce is what makes this dish unforgettable.

Ingredients Used in This Step:
Unsalted butter, all-purpose flour, heavy cream, dry white wine, Dijon mustard, cognac, nutmeg, tarragon, parsley, and Gruyère cheese.

Method:

  1. Create the Roux: Melt butter in a saucepan over medium heat. Whisk in flour to create a roux and cook for 1–2 minutes.
  2. Add Liquid Ingredients: Gradually whisk in the heavy cream, followed by the white wine, Dijon mustard, and cognac. Let the mixture simmer until thickened.
  3. Season and Finish: Stir in the nutmeg, tarragon, and parsley. Add the Gruyère cheese and mix until melted.
  4. Fold in Lobster Meat: Gently fold the diced lobster into the sauce, ensuring it is evenly coated.

💡 Pro Tip: Taste as you go to adjust seasoning, balancing the richness with just a hint of acidity from the wine.


Step 3: Assemble and Broil

The golden, bubbling Parmesan crust brings texture and visual appeal to the dish.

Ingredients Used in This Step:
Lobster-filled shells, Parmesan cheese, and the prepared Thermidor mixture.

Method:

  1. Fill the Shells: Spoon the Thermidor mixture into the reserved lobster shells.
  2. Add the Gratin: Sprinkle a generous layer of Parmesan cheese on top.
  3. Broil to Perfection: Place the shells on a baking sheet and broil for 3–4 minutes, or until the topping is golden and bubbly.

💡 Pro Tip: Keep a close eye while broiling to prevent the crust from burning.


Step 4: Plate and Serve

Plating is where this dish transforms into a true work of art.

Ingredients Used in This Step:
Saffron beurre blanc, roasted vegetables, microgreens, and citrus pearls (optional).

Method:

  1. Drizzle the Sauce: Using a spoon or piping bag, artfully drizzle saffron beurre blanc in a sweeping motion around the plate.
  2. Arrange the Lobster: Place the lobster halves in the center of the plate.
  3. Add Garnishes: Arrange roasted asparagus and heirloom carrots alongside the lobster. Sprinkle with microgreens and a light dusting of smoked paprika. For added brightness, scatter a few citrus pearls.

💡 Pro Tip: Serve the dish on a matte black slate plate for a dramatic contrast that enhances the colors of the lobster and garnishes.
