Lobster Thermidor is a classic recipe that is always a showstopper on any special occasion. While it does have a few steps, none of them are especially hard or require advanced cooking techniques. Our recipe has broken them down so it's easy enough for any cook to follow.
Use a New England or spiny lobster and get fresh tarragon if possible, as its aroma and flavor are beautiful when fresh. The pine of the herb together with the sherry makes a huge impact on the final flavor.
If you've never cooked a lobster, remember that with these shellfishes, less is more. So try to stick to recipes or use very few ingredients, as too many things at the same time only mask the wonderful and mild flavor of its meat. Keep in mind to use 1 or 1.5 pounds of lobster per person, as the final yield will bring about 4 to 8 ounces of meat per person.
- For the Lobster:
- 2 lobsters
- 2/3 cup olive oil

Note: while there are multiple steps to this recipe, this lobster dish is broken down into workable categories to help you better plan for preparation and coking.
Prepare the Lobster
Gather the ingredients.
Preheat oven to 400 F.
With a sharp chef's knife, split the live lobster in half lengthwise. Start with the head side and work the knife back toward the tail. Starting with the head end, the process kills the lobster instantly.
Brush the lobster with olive oil and bake in the preheated oven for 15 minutes.
Make the Béchamel Sauce
In a small skillet or saucepan, make a roux by melting the butter and adding the flour one spoonful at a time. Mix vigorously until all flour is in the saucepan and cook until it is blonde or caramel in color, about 3 to 4 minutes.
Add 1/2 cup of the stock and stir well to combine.
Let the mixture come to a simmer, then slowly add the milk, stirring continuously.
After the mixture has simmered again, add some salt and pepper to taste and then the nutmeg. Be mindful of not letting the béchamel boil.
Remove from heat and reserve.
Make the Thermidor
Remove the lobster from the oven and let it cool.
With the help of a fork, remove all the meat from all parts of the lobster.
Chop the lobster meat coarsely.
In a small frying pan, add the wine, sherry, 1 cup of lobster stock, shallots, and tarragon and boil it down until it is thick in consistency, almost like a glaze.
Add this glaze to the béchamel sauce you've previously made and stir well to combine.
In a separate bowl, mix the cream with the egg yolks.
Slowly add some of the béchamel-glaze mixture into the cream, stirring constantly.
When you get about 1/2 cup of the hot mixture into the bowl with the egg yolks and cream, pour it all back into the rest of the béchamel-glaze mixture. By tempering the cream-egg mixture, you won't get scrambled eggs in your sauce.
Bring to a simmer but don't let boil.
Add the dry mustard and some salt to taste. Cook until the sauce is thickened and remove from heat.
Add the lobster meat to the sauce and mix well.
Assemble the Dish
Preheat the oven to 375 F.
Fill the empty lobster shells with this mixture and bake for 5 to 8 for minutes in the preheated oven. Alternatively, eat the Thermidor outside of the shells on its own with crusty bread or over egg noodles.
Sprinkle a little paprika over the top when you serve for garnish.
Raw Egg Warning
Consuming raw and lightly-cooked eggs poses a risk of food-borne illness.
