Step 1

In a large pan, combine scallops, shrimps, mushrooms, wine, onion, parsley, lemon juice, and a pinch of salt. Bring to a boil, then simmer for 5 minutes. Avoid overcooking to keep seafood tender.

Step 2

Transfer the mixture to a strainer set over a pot to reserve 1 cup of the cooking liquid.

Step 3

In the same pan, melt ¼ cup of butter. Add flour and mix well.

Step 4

Pour in the reserved liquid and the cream all at once, and cook while whisking for about 3 minutes, or until the mixture comes to a boil and thickens.

Step 5

Remove from heat, add the Gruyère cheese, and stir until melted.

Step 6

Add the seafood mixture back into the pan and mix well.

Step 7

Distribute the mixture evenly into 4 oven-safe shells.

Step 8

In a microwave-safe bowl, melt 1 tbsp of butter, then mix in the breadcrumbs.

Step 9

Sprinkle the breadcrumb mixture over the seafood in the shells.

Step 10

Broil for about 2-3 minutes or until the topping is golden and bubbling.
