How to Make Gourmet Seafood Cassolette Recipe
Step 1: Sauté Aromatics
Start by gently heating the olive oil in a skillet over medium heat. Once warm, add the finely chopped shallot and minced garlic. Sauté them for 1 to 2 minutes just until they release their fragrant aroma and soften, setting a savory foundation for the seafood to shine.
Step 2: Cook the Seafood
Next, toss in the shrimp, scallops, and lump crab meat. Season everything with salt, black pepper, and red pepper flakes if you like a little mild heat. Cook for 2 to 3 minutes until the shrimp turn that perfect shell-pink and the scallops become just opaque, careful not to overcook. Then, remove the skillet from heat and set aside so the seafood stays tender and juicy.
Step 3: Craft the Roux and Sauce
In the same skillet, melt 2 tablespoons of unsalted butter over medium heat. Stir in the flour and cook for about 1 minute until it turns a light golden color—that’s your roux building flavor and texture. Slowly whisk in the white wine, letting it bubble gently for 1 to 2 minutes to evaporate the alcohol and intensify taste.
Step 4: Build the Creamy Base
Now, whisk in the seafood stock and heavy cream to your roux, combining everything until smooth and luscious. Add the grated cheese, Dijon mustard, fresh lemon juice, and chopped parsley, stirring well as the sauce thickens over about 2 minutes. This sauce is what makes your cassolette absolutely irresistible.
Step 5: Combine Seafood and Sauce
Return the cooked seafood mixture back into the skillet and gently fold it into the sauce. This ensures every bite is creamy, cheesy, and packed with that fresh seafood goodness.
Step 6: Prepare for Baking
Divide the seafood and sauce evenly into 4 to 6 individual ramekins or a single baking dish if you prefer family-style. In a small bowl, mix together the panko breadcrumbs, extra grated cheese, and melted butter. Sprinkle this crunchy topping evenly over each serving.
Step 7: Bake to Perfection
Place the ramekins on a baking sheet and bake in a preheated oven at 375°F (190°C) for 15 to 20 minutes. Watch as the topping turns a gorgeous golden brown and the bubbling sauce hints at the rich flavors waiting inside.
How to Serve Gourmet Seafood Cassolette Recipe

Garnishes
A finishing touch of freshly chopped parsley or a light drizzle of lemon-infused olive oil brightens the dish beautifully, adding visual appeal and a hint of freshness. A lemon wedge on the side invites a fresh squeeze for those who love an extra citrus kick.
Side Dishes
This cassolette pairs magnificently with crusty artisan bread to soak up every last bit of creamy sauce or a simple green salad dressed with vinaigrette for contrast. Steamed asparagus or sautéed green beans add color and a crisp textural counterpoint to the creamy richness.
Creative Ways to Present
Serve the Gourmet Seafood Cassolette Recipe in elegant individual ramekins for dinner parties, letting each guest enjoy their own bubbling treasure. For a family gathering, a large casserole dish creates a comforting centerpiece perfect for sharing. You can even spoon portions onto toast rounds for sophisticated seafood crostini-style appetizers.
Make Ahead and Storage
Storing Leftovers
If you find yourself lucky enough to have leftovers, let the cassolette cool to room temperature before transferring it to airtight containers. Stored in the refrigerator, it will keep fresh for up to 2 days—perfect for a quick, gourmet meal later.
Freezing
While fresh is best, this dish freezes well if you want to plan ahead. Freeze unbaked cassolette portions in freezer-safe containers for up to 2 months. When ready, thaw overnight in the refrigerator for even baking results.
Reheating
Reheat individual servings gently in a microwave or, even better, in a preheated oven at 350°F (175°C) until warmed through and the topping regains some crispness. Stir a little cream into leftovers if the sauce thickened excessively overnight for silky smoothness.
FAQs
Can I use frozen seafood for this Gourmet Seafood Cassolette Recipe?

The red pepper flakes add just a gentle warmth that enhances the flavors without making the dish truly spicy—feel free to adjust the amount or omit based on your heat preference.
