Ingredients You’ll Need

Each ingredient in this Gourmet Seafood Cassolette Recipe plays a role in layering flavor, from the delicate sweetness of the seafood to the buttery richness of the sauce. When shopping, go for the freshest seafood you can find — it really makes all the difference.

• Mixed seafood (shrimp, scallops, white fish fillets, and mussels): Fresh or properly thawed seafood will ensure the best texture and flavor.
• Butter: Adds richness to the sauce and helps sauté the aromatics.
• Olive oil: Helps balance butter’s richness and prevents burning.
• Onion: Finely chopped to melt into the sauce and add sweetness.
• Garlic: Minced for that essential aromatic punch.
• Dry white wine: Adds acidity and depth, but you can substitute with fish stock if needed.
• Heavy cream: Creates the silky, luscious base of the sauce.
• Fish or chicken stock: Adds umami and thins out the cream just right.
• Grated Parmesan cheese: For that salty, savory kick and creaminess.
• Breadcrumbs (preferably panko): Give the dish a lovely crunchy topping after baking.
• Fresh parsley: Chopped to brighten the flavors and add a pop of color.
• Salt and pepper: To taste — essential to bring out all the flavors.
• Fresh lemon wedges: For garnish and a fresh burst of acidity.

Variations

I love tweaking this Gourmet Seafood Cassolette Recipe depending on what’s in season or what I have on hand. Feel free to personalize it to suit your taste or dietary needs—it’s all about making it yours.

• Variation: Swap in crab meat or lobster for a more indulgent feel. I did this once for a special occasion, and it elevated the dish to something really memorable.
• Dairy-free option: Use coconut milk instead of heavy cream and nutritional yeast in place of Parmesan to keep the creaminess without dairy.
• Spicy twist: Add a pinch of red pepper flakes or a finely chopped chili for a little kick—I find it wakes up the flavors beautifully.
• Vegetarian-style: Use firm tofu and omit the seafood, adding mushrooms and artichoke hearts instead for a satisfying alternative.

How to Make Gourmet Seafood Cassolette Recipe

Step 1: Sauté the Aromatics

Start by melting butter and olive oil together in a skillet over medium heat. Once shimmering, add your finely chopped onion and garlic. Cook them gently until soft and fragrant, about 3-4 minutes. This step builds the flavor base, so don’t rush it or let the garlic brown—that can turn bitter.

Step 2: Deglaze and Simmer the Sauce

Pour in the dry white wine to deglaze your pan, scraping up any little bits stuck to the bottom. Let the wine reduce by half—that intensifies the flavor. Then stir in the heavy cream and fish or chicken stock. Bring to a low simmer to thicken slightly while you prep the seafood.

Step 3: Cook the Seafood Gently

Add the mixed seafood to the sauce, seasoning with salt and pepper. Mussels will open up quickly, and the shrimp and scallops will turn opaque—this only takes a few minutes, so keep an eye to prevent overcooking. Once the seafood is just cooked through, remove from heat.

Step 4: Assemble and Bake

Transfer everything into individual oven-safe dishes or a single casserole. Sprinkle Parmesan and breadcrumbs evenly on top. Pop it under the broiler for 3-5 minutes until the topping is golden and crispy. This contrast of creamy seafood and crunchy topping is exactly what makes this Gourmet Seafood Cassolette Recipe a crowd-pleaser.

How to Serve Gourmet Seafood Cassolette Recipe

Garnishes

I always serve this dish with fresh lemon wedges on the side—the citrus brightens up every bite and cuts through the richness perfectly. A sprinkle of chopped parsley adds freshness and a pop of color, making the dish even more inviting.

Side Dishes

For sides, I love pairing it with crusty bread to soak up that delicious sauce or a simple green salad dressed with lemon vinaigrette to keep things light. Roasted asparagus or sautéed green beans also complement the seafood beautifully without overpowering it.

Creative Ways to Present

When I want to dress things up for a dinner party, I serve the seafood cassolette in charming individual ramekins. It looks so elegant, and guests appreciate the personalized touch. Sometimes, I even lay down a bed of lightly sautéed spinach underneath for an extra layer of color and flavor.

Make Ahead and Storage

Storing Leftovers

I always store leftovers in airtight containers in the fridge and enjoy them within 2 days. Because seafood is delicate, it’s best not to keep it too long. When reheating, I gently warm it on the stovetop to keep the sauce creamy without overcooking the seafood.

Freezing

Freezing this Gourmet Seafood Cassolette Recipe is possible, but I recommend avoiding it if you want the freshest texture. Seafood tends to become a bit rubbery after freezing. If you freeze it, consume it within 1 month and thaw slowly in the fridge.

Reheating

To reheat leftovers, I use a gentle stovetop method over low heat with a splash of cream or stock to loosen the sauce. This keeps everything moist and prevents the seafood from drying out—a microwave tends to do the opposite here.
