Ingredients

Ingredients:
– 2 lobster tails (or whole lobsters, if available)
– 3 tablespoons butter
– 1 shallot, finely chopped
– 1/2 cup white wine
– 1/2 cup heavy cream
– 1 tablespoon Dijon mustard
– 2 teaspoons brandy (or cognac)
– 2 egg yolks
– 1/2 cup grated Gruyère cheese
– 1 tablespoon chopped fresh parsley
– Salt and freshly ground black pepper, to taste
– Paprika, for garnish

For Garnish

How to Make Lobster Thermidor

Step 1: Prepare the Lobster Meat

Bring a large pot of salted water to a boil.
Add the lobster tails (or whole lobsters) and cook for 6-8 minutes for tails or 12-15 minutes for whole lobsters until they turn bright red and the meat is just cooked through.
If using whole lobsters, remove the meat from the shells and chop it into bite-sized pieces. Set the shells aside for later use.
Once cooked, carefully extract the meat from the shells. If using lobster tails, cut them in half lengthwise before removing the meat.

Step 2: Make the Sauce

In a medium skillet over medium heat, melt the butter.
Add the finely chopped shallots and sauté for 2-3 minutes until soft and fragrant.
Pour in the white wine, scraping any browned bits from the bottom of the pan; let it simmer for 2-3 minutes until reduced by half.
Stir in heavy cream and Dijon mustard; bring to a gentle simmer and cook for another 4-5 minutes until thickened.
Remove from heat; whisk in brandy (or cognac) and egg yolks carefully—this will thicken further as it cools.
Add chopped lobster meat into the sauce; stir well to coat. Season with salt and pepper to taste.

Step 3: Assemble and Bake

Spoon the lobster mixture back into reserved shells, dividing it evenly between them while packing gently.
Sprinkle grated Gruyère cheese over each stuffed shell evenly.
Place stuffed shells on a baking sheet; bake in preheated oven at 400°F (200°C) for 10-15 minutes or until cheese is golden brown and bubbly.

Step 4: Garnish and Serve

Once baked, remove Lobster Thermidor from oven; sprinkle with freshly chopped parsley and light paprika dusting for color.
Serve immediately with lemon wedges on side for added freshness.

Common Mistakes to Avoid

When preparing Lobster Thermidor, even small missteps can impact the dish’s final flavor and presentation. Here are some common mistakes to watch out for:

Skipping Fresh Ingredients: Using stale or low-quality ingredients can diminish the overall taste of your Lobster Thermidor. Always opt for fresh lobster and high-quality dairy products for the best results.
Overcooking the Lobster: Cooking the lobster too long can result in tough meat. Keep a close eye on the cooking time to ensure it remains tender and flavorful.
Neglecting the Sauce Consistency: A sauce that is too thin will not coat the lobster meat properly. Make sure to let it simmer until it thickens before combining it with the lobster.
Ignoring Seasoning: Under-seasoning can leave your dish bland. Don’t forget to taste and adjust seasoning with salt and pepper as you prepare.
Rushing the Assembly Process: Packing the lobster mixture too tightly or unevenly can lead to an unattractive presentation. Take your time when filling the shells to create a beautiful dish.
Forgetting Presentation Elements: A well-presented dish elevates any meal. Always garnish with parsley and paprika before serving for an elegant touch.
