The History of Lobster Thermidor: A Classic is Born
Page Contents
Lobster Thermidor is the very definition of French haute cuisine. Combining one of the French mother sauces, velouté, with classic techniques, this impressive dish might seem complicated to make yet comes together in a few easy-to-follow steps.
The name of this decadent dish comes from the 1891 play about the French revolution, Thermidor by Victorien Sardou. Chef Léopold Étienne Mourier of Chez Marie created this lobster dish and presented it to the cast and crew on opening night. While the play only lasted three nights due to its questionable content, this luxurious seafood creation lived on.
By the turn of the 20th century lobster Thermidor crossed the Atlantic and found its way to high end restaurants in the United States, especially in New York City. Famed establishments such as the Hotel Knickerbocker, Waldorf Astoria, and Delmonico’s all included it on their menus.
What is Lobster Thermidor?
Traditional lobster Thermidor combines gently cooked lobster meat with a wine-based cream sauce that is then stuffed back into its own shell and baked until the top is browned and bubbly. The original included tomatoes, English mustard, cayenne, and brandy.
By the time it crossed the pond to America, the tomatoes were left out and instead it became a wine-based cream sauce with the top being sprinkled with cheese, often Gruyere. Here are the most common ingredients you’ll find in lobster thermidor.
- Whole lobsters are traditional. Not only will you get the most flavor, but the shells also allow more surface area for stuffing.
- Velouté sauce. This is one of five French mother sauces. It’s a roux based sauced made with stock, in this case lobster or seafood stock.
- Egg yolks are a popular addition to many Thermidor recipes. They add another layer of richness as well as thickening the sauce and giving it a silky mouthfeel.
- Wine/Sherry/Cognac. Just one can be used, or they can be used in a combination like wine with sherry. They add both a layer of acidity that balances the richness of the dish, and the cognac or sherry echo the natural sweetness of the lobster meat.
- Fresh herbs like tarragon or parsley wakes up the flavors.
- Gruyere cheese is a very classic addition, but parmesan cheese, and even occasionally white cheddar, find themselves in this recipe.
Substitutions and Variations

- While whole lobsters are the traditional option for lobster Thermidor, this same recipe can be made utilizing lobster tails. The lobster meat and Thermidor sauce gets stuffed into the lobster tail shells and baked until golden and bubbly.
- Other types of seafood can be included such as chopped scallops or shrimp. This gives even more complex seafood flavor with depth.
- Like things spicy? Add a generous pinch of cayenne pepper or shake of hot sauce.
- If you absolutely don’t cook with alcohol, you can leave it out entirely. Give a squeeze of lemon to the sauce to add that layer of brightness and acidity.
- If you are dairy free, use your favorite dairy substitutes. Coconut milk will give a mild sweetness, while oat milk will produce a slightly thinner sauce. There are also plant based cream options.
- To make this recipe gluten free, replace the flour in the roux with your favorite gluten free flour. You will want to use a 1 to 1 gluten free flour, so you don’t have to add any additional ingredients.
Seafood Substitutions
Because lobster Thermidor is stuffed back into its own shell, you will need to use a baking dish for any seafood substitution.
Seafood Substitute | Flavor Profile | Texture | Considerations |
Crab Meat | Sweet & Delicate | Tender and flaky | Use high quality lump, jumbo, claw meat, or a combination |
Shrimp | Mild, neutral, slightly sweet | Firm with a slight chew | Choose large shrimp to help prevent from overcooking |
Scallops | Sweet, rich, and buttery | Tender | Sear the scallops briefly, not cooking all the way through. They will finish cooking with the sauce. |
Langostines | Sweet and succulent | Delicate | These are often smaller so adjust cooking time accordingly |
Firm White Fish | Mild | Firm and flaky | Pick a thicker fish such as cod and avoid thin filets like flounder or tilapia. |
Cheese Substitutions
Original Cheese(s) | Cheese Substitute | Flavor Profile | Melting Properties | Considerations |
Gruyere | Comte | Nutty and slighty sweet | Excellent | Similar to Gruyere |
Gruyere | Emmental | Mild and a little nutty | Good | More mild in flavor |
Parmesan | Fontina | Smooth, nutty, and rich | Excellent | Gives richness and creaminess |
Gruyere/Parmesan | Sharp White Cheddar | Sharp and tangy | Good | More bold in flavor |
Gruyere/Parmesan | Monterey Jack | Mild and buttery | Excellent | Mild creamy flavor profile |
Gruyere/Parmesan | Provolone | Comes in different varieties from mild, to smoky, and even pungent | Good | Not as flavorful, but a good melting cheese |
Liquid Substitutions
Ingredient | Substitute | Flavor Contribution | Considerations |
White Wine | Seafood stock | A more neutral flavor profile that accents the lobster | Because it doesn’t have the bright note of wine, you may want to add additional lemon juice. |
Sherry | White wine | Bright and acidic | Doesn’t give the same sweetness as sherry |
Seafood Stock | Chicken or vegetable stock | Neutral and savory | The finished dish will be a little less seafood forward |
Heavy Cream | Plant based cream | Adds richness and a silky texture | Avoid any sweet cream replacements such as coconut cream to keep the dish savory |
Cognac | Brandy | Adds a little sweetness | Cognac is a variety of brandy so it will give a similar flavor profile |
Lobster Tail Thermidor Recipe
If you are looking for a twist on the classic that will impress a crowd, opting for lobster tail Thermidor is a great option. It’s equally as decadent and will demand center stage of your table without being quite as labor intensive. This recipe was adapted from Chef Kardea Brown.

Ingredients
- Four 8-10 ounce lobster tails
- 4 tablespoons unsalted butter
- 1 shallot, finely chopped
- 1 clove garlic, finely chopped
- 2 tablespoons all-purpose flour
- 1/2 cup dry white wine
- 3/4 cup seafood or fish stock
- 1 tablespoon sherry
- 1/2 cup heavy cream
- 1 teaspoon Dijon mustard
- 2 tablespoons finely chopped fresh parsley
- 1 tablespoon fresh lemon juice
- 1 teaspoon finely chopped fresh tarragon
- 1/2 cup grated Gruyere
- 1/4 cup panko breadcrumbs
Directions
- Preheat the broiler on low with the rack set in the middle of the oven. Line a sheet tray with aluminum foil.
- In a pot fitted with a steamer basket, bring 3 inches water up to a rolling simmer. Place the lobster tails in, then cover with a tight-fitting lid. Steam until the meat easily pulls away from the shells, 4 to 5 minutes. Submerge the tails in an ice bath (a bowl with ice and cold water) until completely cooled. Drain and allow to dry on a paper towel-lined tray. Using kitchen shears, cut the soft underside of the tail to expose the meat. Remove the tail meat and cut into bite-sized pieces. Arrange the hollowed tails on the sheet tray cut side up, then set aside.
- In a medium skillet, melt the butter. Saute the shallots until translucent, 4 to 5 minutes, then add the garlic and cook for another minute more. Add the flour and cook, stirring, 1 to 2 minutes. Deglaze the pan with the wine and sherry, then reduce until the skillet is almost dry. Add the fish stock and bring to a simmer, then add the cream and mustard. Reduce for 2 to 3 minutes, then add the parsley, lemon, tarragon, 1/4 cup Gruyere and the reserved lobster meat. Toss to heat the lobster through, then remove from the heat.
- In a small bowl, combine the breadcrumbs and remaining 1/4 cup Gruyere. Divide the lobster filling evenly among all the tail shells, then top with a generous sprinkling of the breadcrumb mixture. Broil until browned on top, 3 to 4 minutes.
