Step‑by‑Step Instructions for Lobster Thermidor

Step 1: Cook the Lobsters
Start by bringing a large pot of salted water to a rolling boil. Carefully add the live lobsters, ensuring they are fully submerged. Boil for about 8–10 minutes, until they turn bright red. Once cooked, immediately transfer them to an ice bath to halt the cooking process. Allow the lobsters to cool for a few minutes before handling.

Step 2: Extract Lobster Meat
Once the lobsters are cool, gently crack the shells using a lobster cracker or mallet, and remove the meat. Chop the tender lobster meat into bite-sized pieces, keeping an eye out for any shell fragments. Set aside the chopped meat and reserve the shells for filling later in the Lobster Thermidor.

Step 3: Preheat the Oven
Preheat your oven to 400°F (200°C) to get ready for that golden, bubbly finish. While the oven heats up, line a baking sheet with parchment paper to catch any drips from the Lobster Thermidor as it bakes. This ensures easy cleanup and a crisp bottom for your dish.

Step 4: Infuse the Milk
In a medium saucepan, combine whole milk, bay leaves, fresh tarragon, chopped onion, and black peppercorns. Bring the mixture to a gentle boil over medium heat, stirring occasionally. Once boiling, remove it from the heat and let it infuse for about 10 minutes. Afterward, strain the mixture to remove the solids, leaving you with a fragrant, flavorful milk base.

Step 5: Make the Roux
In a separate saucepan, melt 4 tablespoons of unsalted butter over medium heat. Once melted, sauté minced garlic and shallots until they’re fragrant and translucent, about 3 minutes. Then, whisk in all-purpose flour and cook for another minute until the mixture is golden. This roux will thicken your Lobster Thermidor sauce beautifully.

Step 6: Add Wine and Brandy
Slowly pour in the dry white wine and brandy, whisking constantly to avoid lumps. Cook the mixture until it thickens slightly, about 3 minutes. This will deepen the flavors of your Lobster Thermidor sauce, creating an irresistible foundation for the remaining ingredients.

Step 7: Create the Sauce
Gradually whisk in the infused milk into the roux mixture, ensuring a smooth consistency. Add Dijon mustard, lemon zest, chopped tarragon, chives, and whipping cream. Stir until fully combined. Finally, fold in the chopped lobster meat, seasoning generously with sea salt and freshly cracked black pepper for extra flavor.

Step 8: Fill the Lobster Shells
Take the reserved lobster shells and carefully fill them with the rich lobster mixture. Pile it high, then sprinkle the top with grated Comté or Gruyère cheese. This will guarantee a cheesy, bubbly crust once baked. Place the filled shells on the prepared baking sheet, ready for the oven.

Step 9: Bake to Perfection
Place the baking sheet in the preheated oven and bake for 20–25 minutes. Watch closely as the cheese melts and begins to turn a beautiful golden brown. You’ll know the Lobster Thermidor is ready when it’s bubbly and the cheese has formed a delightful crust.

Step 10: Garnish and Serve
Once out of the oven, let the Lobster Thermidor cool for a minute. Garnish with fresh dill leaves for a pop of color and added flavor. Serve immediately with lemon wedges on the side, creating an indulgent dish that will impress anyone lucky enough to share in this culinary masterpiece!
