Lobster Thermidor is a rich lobster dish in which pieces of lobster meat are prepared with a sauce that includes heavy cream, egg yolks, butter, mustard, pepper, and herbs. The mixture also usually includes either cognac or brandy. Before the dish is served, the mixture of lobster meat and sauce is usually stuffed into a split, hollowed lobster shell. The stuffed shells may be topped with cheese and browned in the oven before the dish is served. A French dish, Lobster Thermidor is often compared with Lobster Newberg.
This seafood dish not only requires a great deal of time to cook, but also calls for a number of expensive ingredients. For these reasons, Lobster Thermidor is usually served as part of a special occasion. Despite the many variations that exist in present cookbooks, it is believed that the authentic Lobster Thermidor was invented in Paris in the 1890s.
