Gourmet Seafood Cassolette

A seafood cassolette is a classic French-inspired dish that combines tender seafood, creamy sauce, and a golden topping—usually cheese or breadcrumbs. It’s luxurious, full of flavor, and perfect for entertaining or a special dinner.

Ingredients

For the Seafood

8 oz shrimp, peeled and deveined
8 oz scallops, cleaned
8 oz white fish fillets (like cod or halibut), cut into chunks
8 oz mussels or clams, cleaned (optional)
Salt and black pepper, to taste
1 teaspoon lemon juice

For the Sauce

3 tablespoons unsalted butter
1 small onion, finely chopped
2 cloves garlic, minced
2 tablespoons all-purpose flour
1 cup heavy cream
½ cup white wine (optional)
¼ teaspoon nutmeg
1 teaspoon Dijon mustard
Salt and pepper, to taste
2 tablespoons chopped fresh parsley

For the Topping

½ cup grated Gruyère or Parmesan cheese
½ cup breadcrumbs (optional for extra crunch)
1 tablespoon melted butter

For Assembly

4–6 individual cassolette dishes (ramekins or small ovenproof bowls)

Instructions

1. Prepare the Seafood

Season shrimp, scallops, and fish chunks lightly with salt, pepper, and lemon juice.
If using mussels or clams, steam briefly until just opening, then remove from shells (reserve cooking liquid if desired).

2. Make the Creamy Sauce

In a skillet, melt butter over medium heat.
Add chopped onions and sauté until soft and translucent, 3–4 minutes.
Stir in garlic and cook 30 seconds.
Sprinkle in flour and whisk for 1 minute to form a roux.
Gradually add white wine (if using) and heavy cream, whisking constantly until smooth.
Stir in Dijon mustard, nutmeg, and chopped parsley.
Simmer gently for 2–3 minutes until the sauce thickens. Adjust seasoning with salt and pepper.

3. Combine Seafood and Sauce

Add shrimp, scallops, and fish to the sauce. Stir gently to coat.
Let cook for 2–3 minutes on the stove, just enough to start cooking the seafood (it will finish baking in the oven).

4. Assemble the Cassolette

Preheat oven to 375°F (190°C).
Spoon the seafood and sauce mixture into individual cassolette dishes.
Mix breadcrumbs with melted butter and sprinkle evenly over each dish.
Top with grated cheese.

5. Bake

Place dishes on a baking tray.
Bake for 15–20 minutes, or until topping is golden and bubbly.

6. Serve

Garnish with additional parsley or a lemon wedge.
Serve hot with crusty bread, a fresh salad, or steamed vegetables.

Tips for Gourmet Results

Use fresh seafood for the best flavor. Frozen works, but thaw completely and pat dry.
Don’t overcook seafood on the stove—the oven will finish cooking and keep it tender.
White wine adds depth; substitute with seafood stock if you prefer non-alcoholic.
For extra richness, fold in a tablespoon of crème fraîche or cream cheese into the sauce.

Variations

Lobster Cassolette: Replace some seafood with lobster meat for an extra luxurious dish.
Spicy Version: Add a pinch of cayenne or smoked paprika to the sauce.
Vegetable Addition: Mushrooms, peas, or diced bell peppers complement the seafood nicely.

Storage

Best enjoyed fresh, but leftovers can be stored in an airtight container in the fridge for up to 1 day.
Reheat gently in the oven; avoid microwaving to maintain the crust.
