Lobster Thermidor

My great love of Maine and all that it has to offer has taught me many lessons. However, there is one in particular that I am especially grateful for, and that is how to cook Maine lobster.

I was quite surprised to learn that once I knew how to cook lobster, there were dozens of wonderful lobster recipes that I would be able to prepare right in my own kitchen.

It was not just a simple lobster roll or lobster salad that awaited me, but my newfound skills would allow me to create much more elegant dishes, such as this rich Lobster Thermidor.

Lobster Thermidor Recipe

Meat from fresh cooked lobster, or cooked frozen lobster tails, works well for this recipe.

Servings: 2
Preparation time: 45 minutes (includes casserole baking time)

Lobster Thermidor Ingredients:

2 cooked lobster tails, meat coarsely chopped. Save shells for use when baking.
2 tablespoons butter
1 1/2 tablespoons olive oil
2 tablespoons flour
3/4 cup light cream or half and half
1/4 cup dry sherry or white wine
1 tablespoon lemon juice
1 clove minced garlic
1 teaspoon tarragon
1 teaspoon fresh chopped parsley
1/4 cup diced leeks (white part)
1/4 cup minced red pepper
1/2 cup sliced mushrooms
1/2 cup shredded cheddar cheese (white)
1/4 cup parmesan cheese (ideally freshly grated)
1/2 teaspoon paprika
Salt and pepper to taste

Note… For a thicker sauce, use less half and half and less sherry or white wine.


1. Saute mushrooms and red pepper in olive oil. Set aside.
2. Melt butter, add leeks and garlic. Cook 1-2 minutes. Stir in flour to create roux.
3. Stir in wine and then slowly add cream – stirring constantly. Bring to a boil, then reduce heat.
4. Add lemon juice, parsley and tarragon.
5. Add cheddar, and whisk until cheese has melted. Salt and pepper to taste.
6. Stir in sauteed mushrooms, red peppers and lobster.
7. Place lobster tail shells in a casserole dish. Fill shells with mixture and sprinkle with Parmesan and paprika.
8. Bake 10-12 minutes in a preheated 425 degree oven.

Note… When the Lobster Thermidor is made according to this recipe it will run outside of the lobster shells. The shells are meant for decoration, not as a means to contain the sauce.

Serving suggestions:

Although this dish can be served in its baking casserole, I prefer to present it in individual, serving size casserole dishes, with a shell as garnish. Or, the Thermidor is also great when served over puff pastry in individual portions.
This is a very rich recipe. Therefore, I would keep side dishes simple, perhaps serving a green salad as an accompaniment.

Lobster Thermidor New England Style

These is some debate over the origins as well as the ingredients of Lobster Thermidor, a classic French dish. Some historians believe Lobster Thermidor was first introduced in 1894 by Marie’s, a popular Paris restaurant. The Lobster Thermidor recipe was created for the premiere of ‘Thermidor’, a play by Victorien Sardou. The play takes it name for one of the months of the Fresh republican calendar, known as the month of heat (July 19th- August 17th). Another story credits the dish to Chef Tony Girod at Café de Paris, also in Paris. Others believe it was named by Napoleon when he tasted it in the month of Thermidor.  Here is our New England version of  this luxurious lobster dish.

Lobster Thermidor Recipe Ingredients
2 cups dry white vermouth
2 cups water
1 onion, sliced thin
1 carrot, sliced thin
1 celery stalk, sliced thin
6 parsley sprigs
1 bay leaf
1/4 teaspoon dried thyme
3 peppercorns
1 tablespoon dried tarragon
3 live lobsters (2 pounds each)
1 tablespoon lemon juice
1/2 teaspoon salt
1/2 pound fresh mushrooms, sliced

1.Simmer vermouth, water, vegatables, parsley, bay leaf, thyme, pepercorns and tarragon in a large kettle for 15 minutes. Bring to a rolling boil and add live lobsters. Cover and steam for about 16 minutes, or until lobsters are cooked and bright red.
2.While lobsters are cooking, melt butter in a small saucepan. Add lemon juice, salt and mushrooms, and simmer for 10 minutes.  Remove mushrooms from sauce with a slotted spoon and set aside.
3.When lobsters are cooked, remove them from the kettle. Pour butter sauce from mushrooms into kettle and stir well. Boil down mixture rapidly, until liquid in kettle has reduced to about tho cups. Remove kettle from heat and reserve liquid for use as a base for thermidor mixture.
4.Prepare lobsters. Split each into halves, separating body from tail section. Remove sand sacs in the head, and intestinal tubes. Remove lobster meat and dice into chunks. Cut away soft underside of body. Keep the shell halves intact.
5.Wash shells thoroughly and fill with thermidor mixture.
6. Preheat oven to 425 F. Place lobster shells in roasting pan and heat for 10 to 15 minutes, or until lobster is bubbling and top of sauce is nicely browned.

Thermidor Mixture
4 teaspoons of butter
4 teaspoons flour
Diced lobster meat
1/2 cup heavy cream
2 cups reserved lobster stock
2 tablespoons dry sherry or Cognac
Reserved Mushrooms
3 tablespoons butter
1 1/2 cup shredded white bread

1. Melt 4 teaspoons butter in a large saucepan. Stir in flour and blend.
2. Add diced lobster meat. Slowly stir in cream and stock and simmer gently for 10 minutes, stirring frequently.
Season to taste with salt, cayenne and paprika.
3. Remove mixture from heat and add sherry or Cognac and reserved mushrooms.
4. Melt the 3 tablespoons butter and add shredded bread. Cook gently in a saucepan until butter has been absorbed by bread. Fill lobster halves with thermidor mixture. Sprinkle buttered bread on top of each lobster half, and bake as directed.
