Ingredients You’ll Need
Tip: You’ll find the full list of ingredients and measurements in the recipe card below.
For the Scallops:
- 220g (7 1/2 oz) medium raw scallops
- 1/4 teaspoon salt
Mushroom Béchamel Sauce:
- 30g (2 tablespoons) unsalted butter
- 1 shallot, finely diced
- 200g (7 oz) white mushrooms, diced
- 2 tablespoons all-purpose flour
- 1/2 cup hot milk
- 1/2 cup hot heavy cream
- 1/4 teaspoon salt
- 1/8 teaspoon black pepper
- Pinch of ground nutmeg
Cheesy Crust:
- 3/4 cup panko breadcrumbs
- 50g (3 tablespoons) melted butter

- 1/8 teaspoon salt
These ingredients work together to create layers of flavor, from the creamy base to the crispy, cheesy topping.
Let’s Get Started
- Prepare the Scallops
Pat the scallops dry with paper towels and lightly season with salt. This helps them sear properly and enhances their natural flavor. - Sear the Scallops
Heat a pan over medium-high heat with a little butter or oil. Sear the scallops briefly on each side until lightly golden. Remove and set aside—they will finish cooking in the oven. - Make the Mushroom Base
In the same pan, melt butter and sauté the diced shallots until soft. Add mushrooms and cook until they release their moisture and become tender. - Create the Béchamel Sauce
Sprinkle flour over the mushroom mixture and stir well. Gradually add hot milk and cream, stirring constantly to avoid lumps. Cook until the sauce thickens. - Season the Sauce
Add salt, pepper, and a pinch of nutmeg. Stir until smooth and well combined. - Combine Scallops and Sauce
Gently fold the scallops into the sauce, ensuring they are evenly coated. - Assemble the Dish
Transfer the mixture into individual ramekins or baking dishes. - Prepare the Topping
Mix breadcrumbs, melted butter, Gruyère cheese, and salt. Sprinkle evenly over the scallop mixture. - Bake
Bake in a preheated oven at 400°F (200°C) for about 10–15 minutes, or until the top is golden and bubbling. - Serve Immediately
Serve hot for the best flavor and texture.
Servings and Pairing Variations
This recipe typically serves 2–3 people as a main dish or 4 as an appetizer.
For pairing, a light green salad with a simple vinaigrette works beautifully to balance the richness of the dish. Crusty French bread is also a great addition, perfect for soaking up the creamy sauce. If you enjoy wine, a crisp white wine like Sauvignon Blanc or Chardonnay complements the flavors well.
You can also experiment with variations. Add a splash of white wine to the sauce for extra depth, or include a small amount of grated Parmesan for a sharper cheese flavor. Some versions even incorporate a hint of garlic for added aroma.
Storage Tips
Store leftovers in an airtight container in the refrigerator for up to 2 days.
Reheat gently in the oven to maintain the texture of the topping. Avoid microwaving if possible, as it can make the scallops rubbery and the crust soggy.
Freezing is not recommended, as the creamy sauce may separate and the texture of the scallops can change.
FAQs
Can I use frozen scallops?
Yes, just make sure they are fully thawed and patted dry before cooking.
What can I use instead of Gruyère cheese?
Swiss cheese or a mild cheddar can work as substitutes.
Can I prepare this ahead of time?
Yes, assemble the dish and refrigerate, then bake just before serving.
Why are my scallops tough?
Overcooking is usually the cause. Sear briefly and finish cooking in the oven.
