The Stars of the Show: Choosing Your Seafood
The key to an extraordinary Seafood Cassolette lies in the quality of its main ingredients. You can use a combination of fresh or frozen seafood, but for the best flavor and texture, fresh is always preferred. Look for raw shrimp that are peeled and deveined, “dry” sea scallops (which don’t have added phosphates and sear better), and a firm white fish like cod, haddock, or halibut that will hold its shape during cooking.
Ingredients You’ll Need
This recipe relies on a handful of quality ingredients to create its signature creamy sauce and savory seafood base. You’ll need butter, shallots, and garlic to build the aromatic foundation. A dry white wine like Sauvignon Blanc or Pinot Grigio adds a crucial layer of acidity, which is then balanced by the richness of heavy cream and the nutty flavor of Gruyère cheese. A little flour thickens the sauce to the perfect consistency, while fresh parsley adds a touch of brightness at the end.
How to Make This Creamy Seafood Cassolette
Making a stunning Seafood Cassolette is a simple three-step process: preparing the seafood, creating the luscious sauce, and baking it all to golden perfection.
Step 1: Prepare the Seafood
First, pat your seafood completely dry with paper towels; this is crucial for getting a good sear. Season the shrimp, scallops, and fish chunks with salt and pepper. In a large skillet, melt a tablespoon of butter over medium-high heat. Sear the scallops for 1-2 minutes per side until golden, then remove them to a plate. In the same skillet, cook the shrimp for 1-2 minutes until pink. Remove and set aside with the scallops. The fish does not need to be pre-cooked.
Step 2: Make the Creamy White Wine Sauce
Reduce the heat to medium and add the remaining butter. Sauté the minced shallots until softened, then add the garlic and cook for another minute until fragrant. Sprinkle the flour over the shallots and cook, stirring constantly, for one minute to cook out the raw taste. Slowly pour in the white wine, scraping up any browned bits from the bottom of the pan. Let it simmer and reduce by about half. Gradually whisk in the heavy cream and chicken broth, letting the sauce bubble gently until it has thickened enough to coat the back of a spoon.
Step 3: Assemble and Bake
Preheat your oven to 400°F (200°C). Remove the sauce from the heat and stir in half of the shredded Gruyère cheese, the fresh parsley, and a pinch of salt and pepper. Gently fold the seared shrimp, scallops, and raw fish pieces into the sauce. Divide this mixture evenly among four individual oven-safe ramekins. Top with the remaining cheese. Place the ramekins on a baking sheet and bake for 15-20 minutes, or until the sauce is bubbly and the cheese is golden brown and melted.

Tips for Success
- Don’t Overcook the Seafood: The initial sear is just to build flavor and color. The seafood will finish cooking in the oven, so keep the pan time brief to avoid a rubbery texture.
- Use a Dry White Wine: A crisp, dry white wine like Sauvignon Blanc, Pinot Grigio, or an unoaked Chardonnay is best. Avoid sweet wines, which will alter the flavor of the sauce. If you love wine-based sauces, you’ll love this Chicken Marsala Recipe.
- Thicken the Sauce Properly: Allow the sauce to simmer and thicken before adding the seafood. It should be thick enough to coat the ingredients without being watery.
- Serve Immediately: A cassolette is best served hot and bubbling, straight from the oven.
Serving Suggestions
The best way to enjoy a Seafood Cassolette is with plenty of crusty bread, like a French baguette, for sopping up every last drop of the delicious creamy sauce. A simple green salad with a light vinaigrette also makes a perfect accompaniment, providing a fresh, crisp contrast to the rich, savory bake.
