• 6 large sea scallops
• 2 tablespoons unsalted butter
• 1 small shallot, finely chopped
• 1 garlic clove, minced
• 1/2 cup mushrooms, finely sliced
• 1 tablespoon all-purpose flour
• 1/2 cup heavy cream
• 1/4 cup milk
• 1/4 cup grated Gruyère cheese
• 2 tablespoons breadcrumbs
• 1 tablespoon chopped fresh parsley
• 1 tablespoon olive oil
• 1 tablespoon lemon juice
• 1/4 teaspoon salt
• 1/4 teaspoon black pepper
• Pinch of nutmeg

Directions

1. Preheat your oven to 400°F (200°C). Lightly grease small gratin dishes or scallop shells.
2. Pat the scallops dry with paper towels. Season lightly with salt and black pepper.
3. Heat olive oil and 1 tablespoon butter in a skillet over medium heat. Sear the scallops for about 1 minute per side until lightly golden. Remove and set aside.
4. In the same skillet, melt the remaining butter. Add the shallot, garlic, and mushrooms. Cook for 3 to 4 minutes until softened.
5. Stir in the flour and cook for 1 minute while stirring constantly.
6. Slowly pour in the milk and heavy cream, whisking until smooth. Add nutmeg and lemon juice. Simmer for 2 to 3 minutes until slightly thickened.
7. Return the scallops to the sauce and gently coat them.
8. Spoon the mixture into the prepared dishes or shells.
9. Combine the breadcrumbs, Gruyère cheese, and parsley in a small bowl. Sprinkle evenly over the scallops.
10. Bake for 10 to 12 minutes until bubbly and golden brown on top.
11. Serve immediately while hot and creamy.

Variations

Storage/Reheating

Store leftovers in an airtight container in the refrigerator for up to 2 days.

To reheat, place the scallops in an oven-safe dish and warm at 350°F (175°C) for about 10 minutes until heated through. Avoid overheating, as scallops can become rubbery.

Microwave reheating is possible, but the topping may lose its crisp texture.

Freezing is not recommended because the creamy sauce may separate after thawing.
