Lobster Thermidor is a luxurious French dish where tender lobster meat is combined with a rich, creamy mushroom-wine sauce, stuffed back into its shell, topped with cheese, and broiled until golden brown. Created in Paris in 1894 at Marie’s, a renowned restaurant near the Comédie Française theater, it was named after a popular play called “Thermidor” running at the time.

Storage and Reheating
While Lobster Thermidor is best served fresh, you can store and reheat it properly:
- Storage: Keep in an airtight container for up to 2 days
- Reheating:
- Oven method: 350°F for 15-20 minutes
- Avoid microwave (makes sauce separate)
- Add splash of cream when reheating
Serving Suggestions
I love serving Lobster Thermidor with:
- Crisp green salad with light vinaigrette

Common Questions and Answers
Q: Can I make this dish ahead of time?
A: You can prepare the components up to 24 hours ahead. Store the sauce and lobster meat separately, then assemble and broil just before serving.
Q: What if I can’t find live lobsters?
A: While fresh is best, you can use frozen lobster tails. Adjust cooking time accordingly and consider adding extra herbs to enhance flavor.
Q: Is there a substitute for cognac?
A: Yes! You can use brandy or dry white wine. For non-alcoholic version, use fish stock with a splash of lemon juice.
Q: Can I freeze Lobster Thermidor?
A: I don’t recommend freezing as the sauce can separate and the texture of the lobster will change.
Q: How do I know when the sauce is thick enough?
A: The sauce should coat the back of a spoon and leave a clear line when you run your finger through it.
Troubleshooting Common Issues
| Problem | Cause | Solution |
|---|---|---|
| Grainy sauce | Flour not cooked enough | Cook roux longer before adding liquids |
| Rubbery lobster | Overcooked | Reduce initial boiling time |
| Watery filling | Wet lobster meat | Pat meat dry before adding to sauce |
| Burnt topping | Too close to broiler | Lower rack position, watch carefully |
| Separated sauce | Too much heat | Reheat gently, whisk constantly |
