Directions
- Preheat the Oven: Preheat your oven to 375°F (190°C).
- Prepare the Seafood: In a large skillet over medium heat, melt a tablespoon of olive oil or butter. Add the minced garlic and shallot, sautéing until fragrant, about 1-2 minutes.
- Cook the Seafood: Add the shrimp, scallops, and fish pieces to the skillet. Cook for about 3-4 minutes until just opaque. Season with salt and pepper. Remove from heat and set aside.
- Make the Sauce: In a separate saucepan, combine the heavy cream, seafood stock, Dijon mustard, lemon juice, fresh parsley, and thyme. Simmer over low heat for about 5 minutes, stirring occasionally. Stir in half of the grated Gruyère cheese until melted and smooth. Season with salt and pepper as needed.
- Combine Ingredients: In a baking dish, mix the cooked seafood with the creamy sauce until well combined.
- Top with Cheese and Breadcrumbs: Sprinkle the remaining Gruyère cheese and breadcrumbs evenly over the seafood mixture.
- Bake: Place in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and the sauce is bubbling.
