How to Make Gourmet Seafood Cassolette Recipe
Step 1: Sauté Aromatics
Start by heating olive oil in a skillet over medium heat, then add the finely chopped shallot and minced garlic. Cook them gently for 1-2 minutes until fragrant but not browned—this is the aromatic foundation of your dish, awakening your senses with mild sweetness and savory depth.
Step 2: Cook the Seafood
Next, toss in the peeled shrimp, scallops, and lump crab meat, seasoning with salt, black pepper, and red pepper flakes if you want a little heat. Cook for just 2-3 minutes until the shrimp blush pink and the scallops turn slightly opaque—this step prevents overcooking and keeps the seafood tender and juicy. Once cooked, remove the mixture from heat and set aside.
Step 3: Make the Sauce Base
In the same skillet, melt 2 tablespoons of unsalted butter, then stir in the all-purpose flour. Cook the roux for about 1 minute until it turns lightly golden; this step is crucial for that rich, velvety texture. Gradually whisk in the dry white wine, letting it simmer for 1-2 minutes to reduce the alcohol and concentrate the flavors.
Step 4: Build the Creamy Sauce
Now pour in the seafood stock and heavy cream, whisking constantly to keep the sauce smooth and lump-free. Stir in the grated Gruyère or Parmesan cheese, Dijon mustard, fresh lemon juice, and chopped parsley. Allow the sauce to thicken for about 2 minutes, creating a luscious, cheesy bath for the seafood that’s brightened by the lemon and herbs.
Step 5: Assemble and Bake
Return the seafood to the skillet, folding it gently into the creamy sauce. Divide the mixture evenly among 4 to 6 individual ramekins or pour into a single baking dish. In a small bowl, mix panko breadcrumbs with the remaining grated cheese and melted butter, then sprinkle this golden topping generously over the seafood.
Step 6: Bake to Perfection
Place the ramekins on a baking sheet and bake in a preheated oven for 15-20 minutes until the topping is beautifully golden brown and the sauce bubbles merrily underneath. This finishing touch adds a crispy, flavorful crust that contrasts wonderfully with the creamy seafood underneath.
How to Serve Gourmet Seafood Cassolette Recipe

Garnishes
Fresh herbs like chopped parsley or chives sprinkled over each cassolette add a burst of color and freshness, enhancing the dish’s vibrant seafood flavors. A thin twist of lemon zest or a small wedge of lemon on the side can also lift the flavors just before digging in.
Side Dishes
Serve alongside light, crisp salads or steamed green vegetables like asparagus or green beans to balance the richness of the cassolette. Warm, crusty bread or garlic baguette slices are perfect for mopping up every last bit of that heavenly sauce.
Creative Ways to Present
For an elegant touch, serve the dish in individual mini gratin dishes or rustic ceramic pots to make every guest feel pampered. You can even craft mini versions as appetizers for parties by using small ramekins or even oven-safe espresso cups.
Make Ahead and Storage
Storing Leftovers
Your Gourmet Seafood Cassolette Recipe can be stored in an airtight container in the refrigerator for up to two days. The sauce may thicken upon cooling; simply reheat gently to restore its creamy texture.
Freezing
While this dish is best enjoyed fresh for optimal texture, you can freeze it in airtight containers. For freezing, avoid baking first—assemble and freeze the unbaked cassolette, then bake from frozen adding a few extra minutes to cook time.
Reheating
To reheat leftovers, use a low oven setting or microwave on medium power to avoid drying out the seafood. Adding a splash of cream or stock while reheating can help revive the sauce’s silky consistency.
FAQs
Can I use other types of seafood in this cassolette?
Absolutely! This Gourmet Seafood Cassolette Recipe is flexible. You can swap or add lobster, mussels, clams, or firm fish fillets depending on what you have or prefer.
What wine pairs well with this recipe?
A crisp, dry white wine like Sauvignon Blanc, Chardonnay, or a light Pinot Grigio complements the creamy sauce and seafood flavors beautifully without overpowering them.
Is this recipe gluten-free?
The recipe uses all-purpose flour and panko breadcrumbs, which contain gluten. However, you can replace them with gluten-free flour and breadcrumbs to make a gluten-free version.
Can I prepare the seafood ahead of time?
It’s best to cook the seafood fresh right before assembling the cassolette for optimal texture and flavor, but you can chop and prep all other ingredients a day in advance to save time.
How spicy is the dish with the red pepper flakes?
The red pepper flakes add just a gentle warmth. If you prefer no spice or more heat, adjust the amount according to your taste or omit altogether for a milder dish.

Notes
- Use fresh seafood for the best flavor and texture.
- If dry white wine is unavailable, a seafood or chicken broth substitute can be used for a non-alcoholic option.
- Make sure not to overcook seafood initially to prevent toughness, as it will continue cooking during baking.
- Gruyère cheese adds a nutty flavor, but Parmesan is a suitable alternative.
- The breadcrumb topping can be customized with herbs like thyme or rosemary for added aroma.
