  • 3 tablespoons Unsalted Butter Base for the roux; allows for controlled seasoning.
  • 3 tablespoons Flour Forms the roux for a creamy béchamel sauce.

  • 1 cup Heavy Cream Creates a luscious sauce.

Step-by-Step Instructions for Gourmet Seafood Cassolette
  1. In a large pot, combine 1 cup of dry white wine, minced garlic, and fresh thyme. Bring to a gentle simmer over medium heat, then add the mussels. Cover and steam for 4–6 minutes, or until the mussels have opened.
  2. In a medium saucepan, melt 3 tablespoons of unsalted butter over medium heat. Add finely minced shallots and sauté until translucent, about 2–3 minutes. Stir in 3 tablespoons of flour to form a roux, cooking for another minute.
  3. Gradually whisk in the reserved mussel liquid and 1 cup of heavy cream, simmering until the sauce thickens, about 5–6 minutes.
  4. Gently poach 1 cup each of shrimp, scallops, and cubed white fish (like cod or haddock) in the béchamel for about 3–4 minutes, or until they turn opaque.
  5. Carefully fold in the steamed mussels and a handful of chopped fresh parsley to enhance flavors.
  6. Preheat your oven to 400°F (200°C). Spoon the creamy seafood mixture into individual ramekins or a large baking dish.
  7. In a small bowl, mix 1 cup of breadcrumbs with 2 tablespoons of melted butter and ½ cup of grated Gruyère cheese, then sprinkle this topping over the seafood.
  8. Place the assembled Gourmet Seafood Cassolette in the preheated oven and bake for 12–15 minutes, or until the top is golden and crispy.
  9. Remove the cassolette from the oven, allow it to rest for a few minutes, and serve immediately.
