Ingredients For Seafood Thermidor Recipe
Lobster meat: Cooked and chopped, this is the star ingredient of the dish, providing a rich and succulent flavor.
Shrimp: Peeled and deveined, these add a delightful texture and taste to the recipe.
White wine: Adds depth and complexity to the sauce, enhancing the overall flavor.
Heavy cream: Creates a rich and creamy base for the sauce.
Gruyère cheese: A type of Swiss cheese that melts beautifully and adds a nutty flavor. Parmesan can be used as an alternative.
Butter: Used to create the roux, which thickens the sauce.
Flour: Combined with butter to make the roux, giving the sauce its creamy consistency.
Dijon mustard: Adds a subtle tanginess and depth to the sauce.
Salt: Enhances the flavors of all the ingredients.
Black pepper: Adds a touch of heat and balances the richness of the dish.
Technique Tip for This Recipe
When making the roux with butter and flour, ensure you cook it just until it turns a light golden color. This will remove the raw flour taste and add a subtle nutty flavor to your Seafood Thermidor. Be careful not to let it brown too much, as this can alter the flavor profile of the dish.

How to Store or Freeze This Dish
Allow the Seafood Thermidor to cool to room temperature before storing. This helps prevent condensation, which can make the dish soggy.
Transfer the Seafood Thermidor to an airtight container. If you don't have an airtight container, you can use a baking dish covered tightly with plastic wrap or aluminum foil.
Store the container in the refrigerator if you plan to consume the dish within 2-3 days. This ensures the seafood remains fresh and safe to eat.
For longer storage, place the Seafood Thermidor in a freezer-safe container. Make sure to leave a little space at the top of the container to allow for expansion as the dish freezes.
Label the container with the date of storage. This will help you keep track of how long the dish has been stored and ensure you consume it within a safe timeframe.
When ready to reheat, if the dish is frozen, allow it to thaw in the refrigerator overnight. This gradual thawing helps maintain the texture and flavor of the Seafood Thermidor.
Reheat the Seafood Thermidor in an oven preheated to 350°F (175°C) until it is heated through. This usually takes about 20-25 minutes. Cover the dish with aluminum foil to prevent the top from over-browning.
If reheating in a microwave, use a microwave-safe dish and cover it with a microwave-safe lid or plastic wrap. Heat on medium power in 1-2 minute intervals, stirring in between, until the dish is evenly heated.
Avoid reheating the Seafood Thermidor multiple times, as this can degrade the quality and safety of the dish. Only reheat the portion you plan to consume immediately.

Stovetop Method:

Microwave Method:
- Transfer the Seafood Thermidor to a microwave-safe dish.
- Cover with a microwave-safe lid or plastic wrap, leaving a small vent for steam to escape.
- Heat on medium power for 2-3 minutes, stirring halfway through.
- Continue heating in 30-second intervals until the lobster and shrimp are thoroughly warmed.
Sous Vide Method:
- Place the Seafood Thermidor in a vacuum-sealed bag or a resealable plastic bag using the water displacement method.
- Set your sous vide machine to 140°F (60°C).
- Submerge the bag in the water bath and heat for about 30 minutes.
