Ingredients

• 1 whole cooked lobster (or two cooked lobster tails)

• 2 tablespoons unsalted butter

• 2 garlic cloves, minced

• 2 tablespoons finely chopped shallot

• 1 tablespoon all-purpose flour

• ½ cup heavy cream

• ¼ cup grated Parmesan cheese

• ¼ cup grated Gruyère cheese

• 1 teaspoon Dijon mustard

• 1 teaspoon lemon juice

• 1 tablespoon chopped fresh parsley

• Salt, to taste

• Freshly ground black pepper

• Paprika, for garnish

• Lemon wedges, for serving

Step 1: Prepare the Lobster

Remove the lobster meat from the shells and cut it into bite-sized pieces.

Reserve the cleaned lobster shells if you'd like to serve the finished dish in them for a traditional presentation.

Step 2: Make the Sauce

Melt the butter in a skillet over medium heat.

Add the shallot and cook for 2 to 3 minutes until softened. Stir in the garlic and cook for another 30 seconds.

Sprinkle in the flour and stir continuously for about 1 minute.

Slowly add the heavy cream while whisking until the sauce becomes smooth.

Mix in the Dijon mustard, Parmesan cheese, Gruyère cheese, lemon juice, parsley, salt, and black pepper. Stir until the cheeses have melted and the sauce is creamy.

Step 3: Add the Lobster

Fold the lobster meat gently into the sauce until evenly coated.

Cook for 1 to 2 minutes, just long enough to warm the lobster without overcooking it.

Step 4: Fill the Shells

Spoon the lobster mixture back into the reserved lobster shells or transfer it to small oven-safe baking dishes.

Sprinkle a little extra Parmesan and a light dusting of paprika over the top.

Step 5: Bake

Preheat the oven to 400°F (200°C).

Bake for 10 to 12 minutes, or until the top is lightly golden and bubbling.

For additional browning, broil for 1 to 2 minutes while watching carefully.

Step 6: Serve

Garnish with chopped parsley and serve immediately with fresh lemon wedges.

The bright citrus helps balance the richness of the creamy sauce.
