Ingredients
For the Scallops
- 1 pound (450 g) fresh or thawed sea scallops, cleaned
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- Salt, to taste
- ¼ teaspoon freshly ground black pepper
For the Creamy Mushroom Sauce
- 1 cup (100 g) mushrooms, finely sliced
- 2 shallots, finely chopped
- 2 garlic cloves, minced
- ½ cup (120 ml) dry white wine
- ¾ cup (180 ml) heavy cream
- ½ cup (120 ml) seafood stock or low-sodium chicken stock
- 1 tablespoon all-purpose flour
- 1 tablespoon unsalted butter
- 1 teaspoon fresh lemon juice
- 1 tablespoon chopped fresh parsley
- A pinch of ground nutmeg, optional
For the Golden Topping
- ½ cup (50 g) grated Gruyère or Parmesan cheese
- ¼ cup (25 g) fine breadcrumbs
- 1 tablespoon melted butter
- Extra chopped parsley, for garnish
Instructions
- Pat the scallops dry with paper towels and remove any tough side muscles if still attached. Season lightly with salt and black pepper.If the scallops are very large, cut them into bite-sized pieces so they cook evenly. Keep smaller scallops whole for a more traditional presentation.
- Heat the olive oil and 2 tablespoons of butter in a large skillet over medium-high heat. Add the scallops in a single layer, working in batches if necessary.Sear briefly until lightly golden on the outside, approximately 1–2 minutes per side depending on size. They do not need to be fully cooked at this stage because they will finish cooking in the oven. Transfer them to a plate.
- Reduce the heat to medium and add the sliced mushrooms to the same skillet. Cook for 4–5 minutes, stirring occasionally, until they release their moisture and begin to brown.Add the chopped shallots and cook for another 2–3 minutes until softened. Stir in the minced garlic and cook for approximately 30 seconds, taking care not to burn it.
- Pour the white wine into the skillet and scrape up any flavorful browned bits from the bottom. Simmer for 2–3 minutes to reduce the liquid slightly.If you are not using wine, add the stock instead and proceed with the recipe.
- In a small bowl, whisk the flour into a little of the cool stock until smooth. Stir this mixture into the skillet, followed by the remaining stock and heavy cream.Add the remaining tablespoon of butter and the optional nutmeg. Simmer gently for 3–5 minutes, stirring frequently, until the sauce thickens enough to coat the back of a spoon. Avoid boiling vigorously.
- Add the lemon juice and chopped parsley. Taste and adjust the seasoning with salt and black pepper.The sauce should taste creamy and savory, with enough acidity to complement the sweetness of the scallops. If it becomes too thick, add a small splash of stock.
- Return the seared scallops and any accumulated juices to the skillet. Gently fold them into the mushroom sauce.Warm briefly, then remove from the heat. Avoid prolonged cooking at this stage because the scallops will continue cooking in the oven.
- Preheat the oven to 400°F (200°C). Divide the scallop mixture among four oven-safe scallop shells, shallow gratin dishes, or ramekins.Arrange the scallops evenly and spoon the mushroom cream sauce over them. Place the dishes on a sturdy baking tray for easier handling.
- In a small bowl, combine the breadcrumbs, grated Gruyère or Parmesan, and melted butter. Sprinkle the mixture evenly over each portion.For a lighter topping, use a little less cheese and allow the breadcrumbs to provide most of the crisp texture.
- Bake for approximately 8–12 minutes, until the topping is golden and the sauce is bubbling around the edges. Cooking time depends on the size of the dishes and how much the scallops were cooked during searing.The scallops must reach a safe internal temperature of 145°F (63°C). If the topping needs additional color, briefly use the oven grill or broiler, watching carefully to prevent burning.
- Remove the dishes from the oven and let them rest for 2–3 minutes. Sprinkle with fresh parsley and, if desired, a small squeeze of lemon juice.Serve hot with crusty French bread, steamed asparagus, or a simple green salad. Handle the hot shells carefully, as they retain heat.
Notes
- Choose fresh-quality scallops: Fresh or properly thawed scallops provide the best delicate flavor and texture.
- Dry the scallops thoroughly: Excess moisture prevents proper browning and can dilute the sauce.
- Avoid overcrowding the skillet: Sear the scallops in batches if necessary.
- Cook mushrooms until golden: Browning develops a deeper, more savory flavor.
- Use gentle heat for the cream: A gentle simmer helps create a smooth sauce without scorching it.
- Select the right cheese: Gruyère offers a nutty flavor, while Parmesan creates a sharper, saltier finish.
- Watch the topping closely: Breadcrumbs and cheese can brown quickly under a grill or broiler.
- Serve immediately: The sauce and topping are at their best when freshly baked.
