  • Brandy or cognac: Gives a gentle warmth and rich flavor Choose a good sipping brandy if possible
  • Egg yolks: Thicken and enrich the sauce Use eggs with deep orange yolks for extra color

Step-by-Step Instructions

Cook the Lobster:
Bring a generous pot of salted water to a rolling boil and gently lower in the lobster tails or whole lobsters Cook lobster tails for about six to eight minutes and whole lobsters for up to fifteen minutes until they turn bright red and the meat is firm yet tender Do not overcook Transfer the cooked lobster to a plate to cool Slightly crack shells for easier meat removal later
Remove the Meat:
Once cool enough to handle use kitchen shears to cut lobster tails lengthwise or split whole lobsters Remove all meat in large pieces to keep the texture beautiful Carefully reserve the cleaned shells for filling and serving
Sauté the Shallots:
Melt butter in a medium skillet over medium heat Add finely chopped shallots and sauté them gently for two to three minutes until they are translucent and fragrant Stir often to prevent browning as you build a gentle flavor base
Deglaze with Wine:
Pour the white wine into the skillet and use a wooden spoon to scrape up any brown bits from the pan Let the mixture simmer for about three minutes until the wine reduces by half intensifying its flavor
Enrich with Cream and Mustard:
Lower the heat and stir in heavy cream and Dijon mustard Let the sauce gently simmer for four to five minutes until it thickens to a luxurious consistency This is where the richness develops
Finish with Brandy and Egg Yolks:
Remove the skillet from the heat Whisk in the brandy and egg yolks allowing the residual heat to further thicken and enrich the sauce The flavor will deepen and become velvety
Coat the Lobster:
Fold the lobster meat into the sauce until each piece is luxuriantly coated Season with salt and fresh pepper to taste
Stuff and Top the Shells:
Carefully fill the reserved lobster shells with the saucy lobster mixture dividing it evenly Nestle in all the nooks Pack without pressing too tight Sprinkle the tops generously with grated Gruyère for ultimate bubbling crust
Bake to Perfection:
Arrange the stuffed lobster shells on a baking sheet and slide into a hot oven Bake at four hundred degrees fahrenheit or two hundred celsius for about twelve minutes until the cheese is melted and golden
Garnish and Serve:
Remove from the oven and immediately sprinkle with chopped fresh parsley and a dusting of sweet paprika Serve right away for the best texture and flavor Add a wedge of lemon for a bright finish

Ingredient Substitutions

If you cannot find Gruyère try Emmental Jarlsberg or even a good quality Swiss cheese For the wine choose a dry white such as Sauvignon Blanc or Chardonnay Cognac and brandy are interchangeable but omit the alcohol if needed and add a dash more mustard Sea scallops or even firm white fish can stand in for lobster if you want to adapt the recipe for budget or availability

Frequently Asked Questions About Recipes

→ What type of lobster is best for this dish?

Using fresh lobster tails or whole live lobsters yields the most tender, succulent result. Both options work, but ensure the lobster meat is freshly cooked for optimal flavor.

→ Can I substitute another cheese for Gruyère?

Gruyère adds a nutty, creamy flavor, but Emmental or a mild Swiss cheese can be substituted if needed. Avoid overly sharp or hard cheeses for best texture.

→ Is there an alternative to brandy or cognac?

For depth of flavor, brandy or cognac work best, but a splash of dry sherry or even white wine can be used if you prefer to avoid spirits.

→ How do I keep the lobster meat tender?

Avoid overcooking during the boiling step. Boil gently until just cooked through, then remove promptly to prevent toughness before baking with the sauce.

→ What sides pair well with this dish?

Light accompaniments such as buttered asparagus, steamed greens, or a crisp salad make excellent pairings, balancing the dish’s richness without overpowering the lobster’s flavor.

→ Can Lobster Thermidor be prepared in advance?

The filling can be made ahead and assembled in the shells, but for best results, bake just before serving to maintain the cheese’s savory crust and creamy sauce consistency.

Required Ingredients

→ Main Components

01 2 lobster tails or 2 whole lobsters
02 3 tablespoons unsalted butter
03 1 shallot, finely chopped
04 120 millilitres dry white wine
05 120 millilitres heavy cream
06 1 tablespoon Dijon mustard
07 2 teaspoons brandy or cognac
08 2 egg yolks
09 60 grams Gruyère cheese, grated

How to Make It

Step 01

Bring a large pot of generously salted water to a boil. Add lobster tails or whole lobsters and cook for 6–8 minutes for tails or 12–15 minutes for whole lobsters, until shells are vivid red and meat is opaque and just cooked through. If using whole lobsters, remove meat from shells and cut into bite-sized pieces. Reserve shells for serving.

Step 02

Carefully remove the meat from shells. For tails, halve them lengthwise and gently extract the meat. Reserve shells to use as a serving vessel.

Step 03

Melt butter in a medium skillet over medium heat. Add finely chopped shallot and sauté for 2–3 minutes until aromatic and softened.

Step 04

Pour in the white wine, scraping the pan to release any browned bits. Simmer for 2–3 minutes until reduced by half.

Step 05

Add heavy cream and Dijon mustard to the skillet, stirring continuously. Bring to a gentle simmer and cook for 4–5 minutes, allowing the sauce to thicken.

Step 06

Remove pan from the heat. Whisk in brandy or cognac and egg yolks until fully incorporated. The sauce will thicken slightly as it cools.

Step 07

Fold the chopped lobster meat into the sauce, ensuring each piece is well coated. Season to taste with salt and freshly ground black pepper.

Step 08

Spoon the lobster and sauce mixture back into the reserved lobster shells, dividing it evenly. Gently pack mixture to maintain shape.

Step 09

Evenly distribute grated Gruyère cheese over the filled lobster shells.

Step 10

Place filled lobster shells on a baking sheet. Bake in a preheated oven at 200°C for 10–15 minutes, or until cheese is golden and bubbling.

Step 11

Remove from oven and sprinkle with fresh parsley and a light dusting of paprika. Serve immediately, optionally with lemon wedges.
