Frequently Asked Questions
Can I prepare scallop gratin in advance?
You can assemble the shells a few hours ahead and keep them refrigerated, then bake just before serving.
Can I use frozen scallops?
Yes, but make sure they are fully thawed and patted dry before using.
Can I replace béchamel sauce?
You can substitute it with cream, but béchamel gives the most classic and balanced result.
How do I know when scallops are cooked?
They should be opaque and tender. Overcooking will make them rubbery.
Can I add other herbs?
Yes, thyme or chives work well, but keep flavors delicate.
How to Store
Scallop gratin is best enjoyed immediately. If needed, store leftovers in the refrigerator for up to 1 day and reheat briefly in the oven.
How to Freeze
Freezing is not recommended, as scallops may lose their delicate texture and become watery.
Ingredients
How to Make Scallop Gratin with Béchamel

In a bowl, combine the breadcrumbs, grated Parmesan, finely chopped garlic, parsley, and extra virgin olive oil.
Season with salt and black pepper, then mix until well combined. The mixture should be fragrant and crumbly, not greasy. Using a knife, carefully separate the scallop meat from the shell.
Clean the shells if needed and set them aside.

Place a small layer of the breadcrumb mixture inside each shell.
Add a spoonful of béchamel sauce, then place the scallop on top.
Cover with more breadcrumb mixture, pressing lightly to help it adhere. Arrange the filled shells on a baking tray.

Bake in a preheated oven at 200°C (392°F) for about 15 minutes, or until the top is golden brown and lightly crisp.
Serve the scallop gratin hot, straight from the oven, for the best texture and flavor.
