Why You'll Love This Recipe

Ingredients

The backbone of this cassolette is a trio of premium seafood—large shrimp, sweet scallops, and firm white fish such as cod or halibut. A creamy base built from heavy cream, dry white wine, and a splash of fish stock provides richness, while fresh herbs, lemon zest, and a pinch of smoked paprika add brightness and depth. The final garnish of chopped parsley and a drizzle of melted butter ties everything together with a glossy finish.

Seafood & Main Components

• 12 large shrimp, peeled and deveined
• 8 scallops, cleaned and patted dry
• 1 lb white fish fillets (cod, halibut, or sea bass), cut into 2‑inch pieces

Sauce & Aromatics

• 1 cup heavy cream
• ½ cup dry white wine (Sauvignon Blanc or Pinot Grigio)
• ¼ cup fish stock or low‑sodium chicken broth
• 2 cloves garlic, minced
• Zest of 1 lemon

Seasonings & Garnish

• 1 tsp smoked paprika
• ½ tsp freshly ground black pepper
• ½ tsp sea salt (adjust to taste)
• 2 tbsp fresh tarragon, finely chopped
• 2 tbsp fresh parsley, chopped (for garnish)
• 2 tbsp unsalted butter, melted

Each component plays a purpose: the seafood supplies sweet, briny notes; the cream and wine create a luxurious sauce that clings to every bite; aromatics like garlic, lemon zest, and tarragon brighten the richness, while smoked paprika adds a subtle, earthy warmth. The final butter glaze gives the cassolette a glossy, restaurant‑style finish that makes the dish look as good as it tastes.

Step-by-Step Instructions

Preparing the Base

Begin by patting the shrimp, scallops, and fish pieces completely dry with paper towels. This step is crucial because excess moisture will steam the seafood instead of searing it, preventing the golden crust we want. Lightly season all pieces with salt, pepper, and smoked paprika, then set aside for 5 minutes to let the seasoning adhere.

Searing the Seafood

1. Heat the skillet. Place a large, oven‑safe skillet over medium‑high heat and add 1 tablespoon of olive oil. When the oil shimmers (about 2 minutes), it’s hot enough for a quick sear.
2. Sear shrimp and scallops. Add the shrimp and scallops in a single layer, being careful not to crowd the pan. Cook for 1‑2 minutes per side until lightly pink and just opaque. Remove with a slotted spoon and set aside.
3. Sear the fish. Add the fish pieces to the same pan, searing each side for 2‑3 minutes until a thin golden crust forms. This step locks in moisture and adds a subtle caramelized flavor.

Creating the Creamy Sauce

Reduce the heat to medium and add the minced garlic, stirring for 30 seconds until fragrant—be careful not to let it brown. Deglaze the pan with the white wine, scraping up any browned bits; these “fond” pieces are flavor gold. Once the wine reduces by half (about 2 minutes), stir in the fish stock, heavy cream, lemon zest, and tarragon. Simmer gently for 4‑5 minutes until the sauce thickens enough to coat the back of a spoon.

Baking & Finishing

1. Combine everything. Return the seared shrimp, scallops, and fish to the skillet, gently tossing to coat each piece in the sauce. Drizzle the melted butter over the top for added richness.
2. Transfer to the oven. Place the skillet in a preheated 375°F (190°C) oven. Bake for 12‑15 minutes, or until the seafood is opaque throughout and the sauce is bubbling around the edges.
3. Garnish and serve. Remove from the oven, let rest for 3 minutes, then sprinkle chopped parsley over the surface. Serve directly from the skillet or transfer to a shallow casserole dish for a more formal presentation.

Tips & Tricks

Perfecting the Recipe

Flavor Enhancements

Finish the dish with a squeeze of fresh lemon juice for extra brightness, and stir in a pinch of crushed red‑pepper flakes if you enjoy a subtle heat. For added richness, swirl a tablespoon of mascarpone into the sauce just before baking.

Common Mistakes to Avoid

Avoid overcrowding the pan during searing; it creates steam and prevents a golden crust. Also, never add the cream before the wine has reduced, or the sauce may split and lose its silky texture.

Pro Tips

Variations

Ingredient Swaps

Replace the shrimp with lobster tail for a more indulgent version, or swap scallops for mussels to introduce a briny pop. If you prefer a milder flavor, use firm white fish alone. Vegetables like thinly sliced fennel or baby spinach can be folded in for added texture and color.

Dietary Adjustments

For a dairy‑free take, substitute heavy cream with coconut cream and use olive oil instead of butter. Gluten‑free cooks should verify that the broth and wine are certified gluten‑free. To keep it keto, omit any added sugars and serve over cauliflower rice rather than grain‑based sides.

Serving Suggestions

Pair the cassolette with buttery herb‑infused rice, creamy polenta, or a simple quinoa pilaf. A crisp arugula salad dressed with lemon vinaigrette adds a peppery contrast, while toasted baguette slices are perfect for mopping up the luscious sauce.

Storage Info

Leftover Storage

Allow the cassolette to cool to room temperature, then transfer it to an airtight container. Refrigerate for up to 3 days. For longer keeping, portion into freezer‑safe bags, lay flat, and freeze for up to 2 months. Seal tightly to avoid freezer burn and preserve the sauce’s creaminess.

Reheating Instructions

Reheat gently in a 325°F oven, covered with foil, for 15‑20 minutes until heated through. Stir halfway and add a splash of broth or cream if the sauce looks thick. In a microwave, heat individual portions on medium power for 2‑3 minutes, pausing to stir, then finish with a drizzle of melted butter for shine.
