🧾 Ingredients:

For the seafood:

  • 200g (7 oz) raw shrimp, peeled and deveined

  • 200g (7 oz) scallops

  • 150g (5 oz) white fish (e.g., cod or halibut), cut into chunks

  • 100g (3.5 oz) mussels or clams (optional, cleaned)

  • 1 tbsp butter

  • Salt and pepper to taste

  • Splash of white wine (about 2–3 tbsp)

For the sauce:

  • 2 tbsp all-purpose flour

  • 1 cup fish stock (or chicken/vegetable broth)

  • ½ cup dry white wine

  • ½ cup heavy cream

  • 1 tsp Dijon mustard

  • Salt, pepper, and a pinch of nutmeg

  • 1 tbsp chopped fresh tarragon or parsley

For the topping:

  • ⅓ cup grated Gruyère or Parmesan cheese

  • ½ cup fresh breadcrumbs (or panko for crunch)

  • 1 tbsp melted butter

  • Optional: extra herbs or lemon zest

🍳 Instructions:

1. Preheat oven to 400°F (200°C).

2. Sear the seafood:

  • In a skillet, melt 1 tbsp butter over medium-high heat.

  • Lightly season the shrimp, scallops, and fish chunks with salt and pepper.

  • Sear for about 1–2 minutes per side until lightly golden (do not fully cook).

  • Add a splash of white wine and quickly steam the mussels (if using), just until they open.

  • Remove seafood and set aside. Discard any unopened mussels.

3. Make the creamy white wine sauce:

  • In the same pan, melt 2 tbsp butter.

  • Sauté shallots and garlic until soft (2–3 minutes).

  • Stir in flour to make a roux and cook for 1 minute.

  • Gradually whisk in wine and stock, then simmer until slightly thickened.

  • Add cream, Dijon, herbs, nutmeg, salt, and pepper.

  • Let simmer for 5–7 minutes until velvety.

4. Assemble the cassolette:

  • Divide the seafood evenly into 4 individual ramekins or place into a single shallow gratin dish.

  • Pour sauce over the seafood to coat generously.

  • In a small bowl, mix breadcrumbs, cheese, melted butter, and a touch of salt/herbs.

  • Sprinkle the topping over each ramekin.

5. Bake:

  • Bake for 15–20 minutes, until bubbling and golden brown on top.

  • Broil for an extra 1–2 minutes if you want a more toasted crust.

6. Serve:

  • Garnish with chopped parsley, a squeeze of lemon, or a drizzle of truffle oil (optional).

  • Serve with crusty bread or a crisp green salad.

❓ Q&A – Common Questions About Seafood Cassolette

🟢 Q: Can I use frozen seafood?

A: Yes, just thaw it completely and pat dry before searing. Overly wet seafood will make the dish watery.

🔵 Q: I don’t have fish stock—what can I use?

A: Chicken stock, vegetable stock, or even clam juice are good substitutes. Just be mindful of the salt level.

🟠 Q: Can I make this in advance?

A: Yes! Assemble everything ahead and refrigerate. Add the topping right before baking. Bake an extra 5 minutes if cold.

🟣 Q: Is it possible to make this dish lighter?

A: Use half-and-half instead of heavy cream, and reduce the cheese/breadcrumbs. You can also skip butter and sauté with olive oil.

🔴 Q: I’m allergic to shellfish. Can I make this with fish only?

A: Absolutely. Use only white fish, salmon, or even smoked fish like haddock for a rich variation.

🟡 Q: Can I make this dish gluten-free?

A: Yes. Use gluten-free flour for the roux and gluten-free breadcrumbs or crushed GF crackers for the topping.

🟤 Q: What wine pairs best with this?

A: Dry white wines like Sauvignon Blanc, Chardonnay (unoaked), or even a light Pinot Gris work beautifully. Use the same wine in the sauce if possible.

🧄 Bonus Tip:

Add sautéed leeks, wild mushrooms, or a touch of saffron to elevate the flavor to an ultra-gourmet level.
