Ingredients
Scale
- 1 lb large shrimp, peeled and deveined
- 1 lb sea scallops, tough side muscle removed
- 2 tablespoons butter
- 1 shallot, finely chopped
- 2 cloves garlic, minced
- 1/4 cup all-purpose flour
- 2 cups milk
- 1/2 cup heavy cream
- 1 cup shredded Gruyere cheese
- 1/2 cup shredded Parmesan cheese
- 1/4 cup chopped fresh parsley
- Salt and freshly ground black pepper to taste
- 1/4 cup breadcrumbs (optional)
Instructions
- Preheat your oven to 375°F (190°C).
- Pat the shrimp and scallops dry with paper towels.
- In a large oven-safe skillet or gratin dish, melt the butter over medium heat.
- Add the chopped shallot and cook until softened, about 3-4 minutes.
- Stir in the minced garlic and cook for 1 minute more until fragrant.
- Sprinkle the flour over the shallots and garlic, stirring constantly to form a roux. Cook for 1-2 minutes.
- Gradually whisk in the milk and heavy cream until smooth. Bring to a simmer, stirring occasionally, until the sauce thickens.
- Remove the skillet from the heat. Stir in the Gruyere and Parmesan cheeses until melted and the sauce is creamy.
- Season the sauce with salt and pepper to taste.
- Gently fold in the shrimp and scallops, coating them evenly with the sauce.
- Sprinkle with fresh parsley. If using, top with breadcrumbs.
- Bake for 15-20 minutes, or until the seafood is cooked through and the topping is golden brown and bubbly.
- Let stand for a few minutes before serving.
Notes
- For a crispier topping, you can broil the gratin for the last 1-2 minutes, watching carefully to prevent burning.
- Feel free to add other herbs like chives or dill for extra flavor.
- This dish can be prepared ahead of time and baked just before serving.
