How to Make Creamy Seafood Cassolette Recipe
Step 1: Prepare Your Baking Dishes
Start by preheating your oven to 375°F (190°C). This step ensures you get that beautiful, evenly golden crust once it’s time to bake. Grease individual cassolette dishes if you want to serve each guest their own little pot of heaven, or use a single large baking dish for easy sharing.
Step 2: Sauté Aromatics
In a large skillet, heat your butter and olive oil over medium heat—they’ll work together for a deeply flavorful base. Toss in the chopped onion and garlic, and let them soften and become fragrant. This duo will lay the foundation for the whole Delicious Recipe.
Step 3: Gently Cook the Seafood
Add your mixed seafood to the skillet. Sauté everything for just 2-3 minutes; you want the seafood to start cooking, but not finish, so it stays tender when baked. Scoop out the seafood and set it aside on a plate—you’ll add it back in soon.
Step 4: Deglaze with Wine
Pour that half cup of dry white wine into the skillet. Scrape up any delicious brown bits left from the seafood and aromatics—the wine will quickly reduce and infuse the sauce with brightness and depth.
Step 5: Make the Cream Sauce
Stir in the heavy cream and the fish or chicken stock. This mixture should bubble gently and thicken as you simmer it for about 5 minutes. You’re aiming for a luxurious sauce that will coat every bite of seafood in the finished Delicious Recipe.
Step 6: Return Seafood and Finish the Filling
Add the seafood back to the pan, sprinkle with salt and pepper, and stir gently. Be careful not to break up the fish! Make sure everything is well coated and heated through before moving on to the next step.
Step 7: Assemble and Top
Spoon the succulent seafood and that glorious sauce into your baking dishes. Shower the tops with grated Parmesan cheese and a generous layer of panko breadcrumbs. This is where the Delicious Recipe gets its famous crackling crust.
Step 8: Bake to Perfection
Slide the casseroles into your preheated oven and bake for 12–15 minutes. The tops should be bubbling and a gorgeous golden brown—resist the urge to dig in right away! They’ll be piping hot.
Step 9: Finish and Serve
Once out of the oven, scatter fresh parsley over the top and garnish with lemon wedges. The burst of green and citrus aroma will turn this Delicious Recipe into an unmistakably elegant crowd-pleaser.
How to Serve Creamy Seafood Cassolette Recipe

Garnishes
The right garnish brings this dish to life—don’t skip it! Sprinkle lots of freshly chopped parsley over each cassolette right before serving for a pop of color and freshness. Lemon wedges are more than decorative: a quick squeeze over the hot seafood brightens every flavor.
Side Dishes
This Delicious Recipe pairs beautifully with a crisp green salad dressed in a tangy vinaigrette. Crusty French bread is a must for soaking up any luscious cream sauce left in the dish. For heartier meals, try buttery mashed potatoes or a light risotto on the side.
Creative Ways to Present
Make it truly special by serving the cassolette in individual oven-safe ramekins for a dinner party. Or, for a rustic touch, spoon the filling into hollowed-out bread bowls and bake until golden. For easy entertaining, prepare the whole Delicious Recipe in one large casserole dish and serve family-style, straight from the oven. The bubbling crust always gets a round of applause!
Make Ahead and Storage
Storing Leftovers
If you’re lucky enough to have leftovers, transfer them to an airtight container and keep them in the fridge for up to 2 days. The flavors will meld overnight, making the Delicious Recipe even creamier and more irresistible the next day.
Freezing
This dish actually freezes surprisingly well! Portion the cooled cassolette into freezer-safe containers and freeze for up to 2 months. For best results, wait to top with breadcrumbs and cheese until ready to bake, so you still get that signature crispy crust.
Reheating
Warm up individual portions in a 350°F oven for about 15 minutes, or until heated through and bubbling. If you saved the topping separately, sprinkle it on before reheating for a freshly crisped crust. Avoid the microwave, as it can make seafood rubbery and the sauce grainy.
FAQs
Can I use frozen seafood for this Creamy Seafood Cassolette Recipe?
Absolutely! Just thaw completely and pat dry before cooking to avoid extra liquid in the sauce. Frozen seafood works beautifully and helps make this Delicious Creamy Seafood Cassolette Recipe weeknight-friendly.
What’s the best wine to use in the sauce?
Any dry white wine will work, but a crisp Sauvignon Blanc or Pinot Grigio is ideal. Avoid anything too sweet, as it can overpower the delicate seafood flavors.
Can I make this Creamy Seafood Cassolette Recipe dairy-free?
It’s possible! Swap the heavy cream for full-fat coconut milk and use a vegan parmesan substitute. The result will be a bit different but still creamy and delicious.
Do I need to peel the shrimp and clean the mussels?
Yes—peel and devein the shrimp and make sure your mussels are scrubbed and debearded before cooking. These steps make for an elevated, company-worthy bite every time.
What’s the difference between cassolette and casserole?
A cassolette is typically a single-serving French dish, while a casserole is larger and baked family-style. Either way, this Delicious Creamy Seafood Cassolette Recipe adapts easily to both formats—just use the cookware that fits your occasion.
