Ingredients For Lobster Thermidor Recipe
Lobsters: The main ingredient, providing the succulent meat for the dish.
Heavy cream: Adds richness and creaminess to the sauce.
Dry white wine: Enhances the flavor of the sauce with a subtle acidity.
Brandy: Adds depth and complexity to the sauce.
Butter: Used to create the base of the sauce and adds a rich flavor.
Flour: Helps thicken the sauce to the right consistency.
Dijon mustard: Adds a tangy, sharp flavor to the sauce.
Egg yolks: Enrich the sauce and help bind it together.
Gruyère cheese: Provides a creamy, nutty topping that melts beautifully.
Salt and pepper: Essential seasonings to enhance the overall flavor.
Technique Tip for This Recipe
When preparing lobster, make sure to boil them just until they turn bright red, which typically takes about 8 minutes. Overcooking can make the meat tough and rubbery. After boiling, immediately transfer the lobsters to an ice bath to stop the cooking process and make it easier to handle when removing the meat from the shells. When making the sauce, ensure to cook the flour and butter mixture (roux) for a full 2 minutes to eliminate any raw flour taste. Reducing the white wine and brandy by half concentrates their flavors, adding depth to the dish. Finally, when incorporating the egg yolks, temper them by slowly adding a bit of the hot sauce first to prevent curdling.

How to Store or Freeze This Recipe
- Allow the lobster thermidor to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
- Transfer the cooled lobster thermidor into an airtight container. If you have multiple portions, consider using separate containers to make reheating easier.
- Label the container with the date to keep track of freshness. Lobster thermidor can be stored in the refrigerator for up to 2 days.
- For freezing, wrap each lobster shell tightly in plastic wrap to prevent freezer burn. Then, place the wrapped shells in a heavy-duty freezer bag or an airtight container.
- When ready to reheat, thaw the lobster thermidor in the refrigerator overnight. This gradual thawing helps maintain the texture and flavor of the lobster meat.
- Preheat your oven to 350°F (175°C). Place the lobster thermidor in an oven-safe dish and cover it with aluminum foil to prevent drying out.
- Heat for about 15-20 minutes or until the internal temperature reaches 165°F (74°C). If you prefer a crispy top, remove the foil for the last 5 minutes of heating.
- Avoid using a microwave to reheat lobster thermidor as it can make the lobster meat rubbery and the sauce may separate.
How to Reheat Leftovers
- Preheat your oven to 350°F (175°C). Place the Lobster Thermidor in an oven-safe dish, cover with aluminum foil to prevent drying out, and heat for about 15-20 minutes until warmed through.
- For a quicker method, use a microwave. Place the Lobster Thermidor on a microwave-safe plate, cover with a microwave-safe lid or plastic wrap, and heat on medium power for 2-3 minutes. Check and stir halfway through to ensure even heating.
- If you prefer a stovetop method, heat a skillet over medium-low heat. Add a small amount of butter or olive oil to the pan, place the Lobster Thermidor in the skillet, and cover. Heat for about 5-7 minutes, stirring occasionally, until warmed through.
- For a more gourmet touch, use a double boiler. Place the Lobster Thermidor in the top part of the double boiler and gently heat over simmering water for about 10-15 minutes, stirring occasionally, until hot.
