🦞 Gourmet Seafood Cassolette

⭐ Ingredients (serves 4)

Seafood

8 oz scallops
8 oz shrimp, peeled & deveined
6–8 mussels or clams (optional)
8 oz lobster meat or firm white fish (cod, halibut, or monkfish)

Base Sauce

2 tbsp butter
1 tbsp olive oil
1 shallot, finely minced
2 cloves garlic, minced
1 cup sliced mushrooms
2 tbsp all-purpose flour
½ cup dry white wine
1 cup seafood stock (or chicken stock)
½ cup heavy cream
½ tsp Dijon mustard
Salt & white or black pepper
Pinch of paprika
Fresh thyme or tarragon (½–1 tsp)

Gratin Topping

½ cup shredded Gruyère or Parmesan cheese
¼ cup breadcrumbs (panko works beautifully)
1 tbsp melted butter

Optional Add-Ins

Splash of cognac
Chopped chives for garnish
A drizzle of truffle oil (for a luxury finish)

🔧 Instructions

1. Prepare and sear the seafood

Pat seafood dry and season lightly with salt and pepper.
Heat a skillet with a little butter/oil over medium-high.
Quickly sear shrimp and scallops just until lightly golden (they’ll finish in the oven).
Remove and set aside.
Steam mussels/clams in a splash of wine until they open (discard any that stay closed).

2. Make the creamy cassolette sauce

In the same skillet, lower heat to medium. Add 2 tbsp butter.
Sauté shallots and garlic until fragrant.
Add mushrooms and cook until softened.
Sprinkle flour over the mixture; stir to form a roux.
Pour in white wine—scrape up the browned bits.
Add seafood stock and simmer 2–3 minutes until thickened.
Stir in cream, Dijon, herbs, paprika, salt & pepper.
Taste and adjust seasoning.

(Optional: Add 1–2 tsp cognac for a classic French depth.)

3. Combine seafood & sauce

Add seared shrimp, scallops, lobster/fish pieces, and mussels/clams to the sauce.
Gently fold together—don’t over-stir or the seafood may break.

4. Assemble and bake

Preheat oven to 400°F (200°C).
Spoon mixture into individual ramekins or a shallow casserole.
Mix breadcrumbs, cheese, and melted butter; sprinkle generously on top.
Bake 10–12 minutes, or until golden and bubbling.
Broil 1–2 minutes for extra browning if desired.

5. Serve

Serve hot with:

Crusty French bread
Buttered noodles
A light green salad
Champagne or crisp white wine

Finish with fresh herbs or a light drizzle of truffle oil for a truly gourmet touch.

💡 Chef Tips

Gruyère is classic, but Parmesan or Comté works beautifully.
Don’t overcook the seafood—quick sear + brief bake keeps it tender.
Add a pinch of saffron to the sauce for a luxurious golden flavor.
For a richer dish, swap part of the cream with crème fraîche.
