There’s something about seafood that feels like a celebration. Every time I make this Gourmet Seafood Cassolette, I’m instantly transported back to summers spent along the coast with my family. I can still hear the sound of the waves, smell the salty breeze, and feel the excitement of those seafood dinners we would all look forward to after long days on the beach.

One evening stands out in my memory: a cozy little bistro by the water, where I had my first-ever seafood cassolette. The delicate combination of tender shrimp, buttery scallops, and sweet lump crab meat baked under a golden cheesy crust felt like pure magic. I knew right then I had to learn how to recreate that dish at home.

Fast forward to today, this recipe has become a cherished tradition in my kitchen — perfect for date nights at home, special family dinners, or even as a fancy seafood dinner party centerpiece.

Today, I’m so excited to walk you through it, just like I would if you were in my kitchen with me — cozy, barefoot, sipping a glass of Sauvignon Blanc, and cooking up something unforgettable. 🍷💬

Ingredient Notes: What You Need and Why It Matters 🍤

Seafood

½ lb Shrimp (peeled and deveined):
Fresh, firm shrimp are crucial for that juicy bite. If using frozen, be sure to thaw and pat dry completely to avoid excess moisture.
½ lb Scallops (patted dry):
Scallops bring that luxurious, melt-in-your-mouth texture. Choose sea scallops over bay scallops for a meatier feel.
½ lb Lump Crab Meat (picked over for shells):
Sweet, delicate crab adds depth and richness. Look for “lump” or “jumbo lump” crab for the best texture.

Aromatics and Flavor Builders

Shallot (finely chopped):
More delicate and slightly sweeter than onion — it melts into the sauce beautifully.
Garlic (minced):
A must-have for that savory base note!
Olive Oil:
Adds fruity richness and helps everything sauté evenly.
Salt and Black Pepper:
Always essential — good seasoning brings all the flavors to life.

Liquids and Creaminess

Dry White Wine (such as Sauvignon Blanc):
Adds brightness and acidity that balance the richness of the cream and seafood. 🍷
(Tip: Never cook with wine you wouldn’t drink!)
Heavy Cream:
For that dreamy, velvety sauce. Light cream won’t thicken properly — full-fat is the way to go!
Seafood or Fish Stock:
Enhances the oceanic flavors. If you can’t find seafood stock, chicken stock can work — but the seafood flavor will be milder.
Dijon Mustard:
Just a teaspoon, but it gives the sauce a beautiful backbone of flavor without making it “mustardy.”

Finishing Touches

Grated Gruyère Cheese (or Swiss):
Nutty, melty, perfect for that beautiful golden topping.
Fresh Parsley:
Brings freshness and a pop of color.
Lemon Juice:
A bright squeeze at the end wakes up all the flavors.
Smoked Paprika (optional):
Adds a whisper of smokiness — highly recommended!

Topping

Breadcrumbs:
For that irresistible crunchy topping. Panko works too for extra crunch!
Melted Butter:
Because everything’s better with a buttery breadcrumb crust. 🧈

Equipment You’ll Need 🔪

Large skillet (preferably non-stick or stainless steel)
Medium saucepan
Baking dish (ceramic or glass)
Mixing bowls
Whisk
Small bowl for breadcrumbs
Kitchen paper towels (for drying seafood)
Cooking thermometer (optional, for checking seafood doneness)

👉 Can You Make It Without Fancy Equipment?
Absolutely! If you don’t have a skillet and a baking dish, you can use a regular oven-safe pan for everything. Just make sure it’s deep enough to hold the sauce and seafood without spilling.

Step-by-Step Instructions: How to Make Seafood Cassolette 🧑‍🍳

Step 1: Prep the Seafood

🧻 Pat the shrimp and scallops dry with paper towels. Moisture is the enemy of browning!
🦀 Gently pick over the crab meat to remove any bits of shell.

Tip: Keep the seafood cold until you’re ready to cook — it helps them sear better.

Step 2: Sauté the Aromatics

🍳 Heat the olive oil in a large skillet over medium heat.
🧅 Add the finely chopped shallot and sauté until soft and translucent, about 3 minutes.
🧄 Stir in the minced garlic and cook for another 30 seconds until fragrant — but don’t let it burn!

Step 3: Sear the Seafood

🔥 Increase the heat slightly and add the shrimp and scallops.
🌟 Season with salt and black pepper.
🍤 Cook for about 2–3 minutes until just beginning to turn opaque (they’ll finish cooking in the oven later).
🦀 Gently fold in the crab meat and cook another 1 minute just to warm through.

Note: Be gentle with the crab — you want big, juicy lumps, not shredded bits!

Step 4: Deglaze and Make the Sauce

🍷 Pour in the white wine, scraping up any delicious browned bits from the bottom.
🍚 Let it simmer and reduce by half (about 2 minutes).
🥛 Stir in the heavy cream and seafood stock. Simmer gently for another 3 minutes.
🥄 Whisk in the Dijon mustard until fully incorporated.

Step 5: Assemble and Bake

🧀 Stir in half of the Gruyère cheese and the lemon juice.
🌿 Add the parsley and (optional) smoked paprika for extra depth.
🥘 Pour everything into a greased baking dish.
🍞 In a small bowl, mix the breadcrumbs with the melted butter. Sprinkle evenly over the top.
🧀 Finish with the remaining Gruyère cheese.

Step 6: Bake to Golden Perfection

🔥 Preheat the oven to 400°F (200°C).
⏲️ Bake for 12–15 minutes until bubbling and the top is golden brown.

Tip: If the top isn’t browning as much as you’d like, you can broil it for 1–2 minutes at the end — just keep a close eye so it doesn’t burn!

Pro Tips for the Best Seafood Cassolette 🌟

Use the freshest seafood you can find. Freshness truly shines in a dish like this.
Don’t overcook the seafood. Slightly undercooked before baking is perfect — they’ll finish beautifully in the oven.
Choose a good-quality white wine. It really impacts the final flavor more than you might expect.

Tips for the Best Seafood Cassolette 🎯

Pat Seafood Dry: Essential for a perfect sear without steaming.
Season Each Step: Don’t wait to season everything at the end — layering flavor is key!
Golden, Not Burnt: Breadcrumbs brown quickly — check often during the last few minutes of baking.

Ingredient Swaps & Variations 🍽️

Swap the Seafood: Lobster chunks or firm white fish (like cod) work wonderfully too!
Cheese Choices: Fontina or Monterey Jack are great substitutes for Gruyère.
Low-Carb Version: Skip the breadcrumbs and just sprinkle more cheese on top.

Frequently Asked Questions (FAQ) ❓

Q: Can I make Seafood Cassolette ahead of time?

A: Absolutely! You can fully prepare the dish (up to the breadcrumb topping step), cover it tightly with foil or plastic wrap, and refrigerate for up to 24 hours. When ready to bake, let it sit at room temperature for about 20–30 minutes while the oven preheats, then bake as directed.

Q: Can I freeze Seafood Cassolette?

A: Yes, but with a little caution. Because this dish has cream, freezing might cause slight texture changes (cream can separate a bit). If you must freeze it, do so before baking, tightly wrapped, for up to 2 months. Thaw overnight in the fridge before baking.

Q: What wine pairs best with Seafood Cassolette?

A: A crisp, dry white wine is ideal — think Sauvignon Blanc, Pinot Grigio, or even a buttery Chardonnay if you love richer flavors. A glass while you cook makes the whole experience even better! 🍷

Q: Is it possible to make this gluten-free?

A: Yes! Simply swap regular breadcrumbs with gluten-free breadcrumbs. Double-check that your stock and Dijon mustard are gluten-free too.

Special Equipment Notes 🔧

Although a traditional ceramic or glass baking dish makes for a beautiful presentation, you don’t need fancy equipment to make this recipe unforgettable. Here are some flexible tips:

No Baking Dish? Use any oven-safe skillet or sauté pan.
No Whisk? A fork can work just fine for blending the sauce.
Seafood Thermometer: Optional, but helpful if you’re new to seafood cooking. Perfectly cooked shrimp should reach 120°F, scallops about 125°F.

Remember: Seafood cooks very quickly, so trust your eyes and nose too — opaque, firm flesh is the goal!
