Step‑by‑Step Instructions for French Lobster Thermidor
Step 1: Prepare Lobsters
Begin by bringing a large pot of salted water to a boil. Carefully add the live lobsters and cook for 8-10 minutes until they turn bright red. Once cooked, remove them from the pot and let them cool for a few minutes. Crack open the shells and extract the succulent lobster meat, setting it aside for later use in your French Lobster Thermidor.
Step 2: Sauté Aromatics and Mushrooms
In a large skillet over medium heat, melt 3 tablespoons of unsalted butter until foamy. Add finely chopped shallots and sauté for about 2 minutes until they turn translucent. Next, stir in sliced mushrooms, cooking for an additional 4-5 minutes until they become tender and fragrant, creating a delicious base for your creamy sauce.
Step 3: Create Sauce Base
Pour in a generous splash of white wine, scraping the bottom of the skillet to deglaze. Let the mixture simmer for 3-4 minutes, allowing the wine to reduce. Then, add 1 cup of heavy cream and stir continuously, thickening the sauce over medium heat for another 3 minutes until it becomes velvety and coats the back of a spoon beautifully.
Step 4: Combine Ingredients
Gently fold the lobster meat into the warmed sauce, along with a teaspoon of paprika for an added depth of flavor. Sprinkle half of the grated Parmesan cheese into the mixture and season generously with salt and pepper to taste. This harmonious blend will create the richness that defines your French Lobster Thermidor.
Step 5: Fill Shells and Broil
Preheat your broiler to high. Carefully spoon the rich lobster and sauce mixture back into the lobster shells, ensuring an even distribution. Top each filled shell with the remaining Parmesan cheese. Place the shells on a baking tray and broil for 3-5 minutes, watching closely until the cheese is melted and golden brown, producing a delightful crust.
Step 6: Serve Hot
Once perfectly broiled, remove the French Lobster Thermidor from the oven. Allow it to cool slightly before serving. Pair this lavish dish with a crisp salad or warm crusty bread to complement the rich flavors, creating a gourmet dining experience that will impress family and friends alike.
