Step‑by‑Step Instructions for Seafood Gratin
Step 1: Prepare Seafood
Start by thoroughly drying the mixed seafood. If you’re using larger fish fillets, cut them into bite-sized pieces. Season with salt and pepper to enhance the flavors. Set aside while you prepare the aromatic base, allowing the seafood to absorb the seasoning.
Step 2: Create Aromatic Base
Preheat your oven to 200°C (400°F). In a large skillet, heat the olive oil over medium heat. Add the finely chopped onion and sauté for about 5 minutes until it becomes translucent. Stir in the minced garlic, cooking for an additional 1-2 minutes until fragrant and golden, creating a rich flavor foundation for your Seafood Gratin.
Step 3: Make Creamy Sauce
Reduce the skillet heat to low. Add the butter, stirring until melted. Whisk in the all-purpose flour to create a roux, cooking for 1-2 minutes until it forms a smooth paste. Gradually add the milk and heavy cream, whisking continuously for 3-4 minutes until the sauce thickens to a creamy consistency, perfect for enveloping your seafood.
Step 4: Combine
Remove the skillet from heat and gently fold the prepared seafood into the creamy sauce. Mix well until each piece is coated, ensuring the flavors meld together. Taste and adjust seasoning with additional salt and pepper if needed, creating a harmonious blend for your Classic Seafood Gratin.
Step 5: Add Topping
Transfer the seafood and sauce mixture into a greased baking dish, spreading it evenly. Sprinkle the grated cheese generously over the top, followed by the breadcrumbs. For extra crunch, you can mix the breadcrumbs with melted butter before sprinkling, enhancing the texture of your Seafood Gratin.
Step 6: Bake
Place the baking dish in the preheated oven and bake for 20-25 minutes. Watch as the topping turns golden brown and the edges bubble enticingly, showcasing the creamy goodness underneath. This visual cue indicates that your gratin is ready to delight.
Step 7: Serve
Once baked, remove the Seafood Gratin from the oven and let it rest for about 5 minutes before serving. This allows the flavors to settle. Garnish with freshly chopped parsley for a pop of color, and then scoop out portions to enjoy the creamy, comforting richness you’ve created.

Classic Seafood Gratin Recipe FAQs
What type of seafood should I use in my gratin?
Absolutely! You can use a delightful mix of seafood such as shrimp, scallops, and white fish to create the perfect flavor combination. If you’re feeling adventurous, you can also try lump crab or even lobster for a more luxurious version. Just ensure everything is fresh or properly thawed and patted dry to avoid added moisture.
How can I store leftovers from my Seafood Gratin?
For sure! Store any leftover Seafood Gratin in an airtight container in the fridge for up to 2 days. Be sure to let it cool completely before sealing. When reheating, it’s best to do so in the oven covered with foil to prevent drying out, which should take about 15-20 minutes at 180°C (350°F).
Can I freeze Seafood Gratin?
Yes, you can! To freeze, prepare your gratin but do not bake it. Wrap the unbaked dish tightly in plastic wrap, then in foil. It can be kept in the freezer for up to 2 months. When you’re ready to enjoy, simply thaw it overnight in the fridge and bake it as instructed, usually at 200°C (400°F) for 20-25 minutes.
What if my gratin turns out too watery?
No worries! If your gratin is watery, it could be due to the seafood not being fully dried or using too much cream. Next time, ensure your seafood is thoroughly dried before mixing into the sauce, and consider reducing the amount of heavy cream. If it happens, you can thicken the mixture with a little more flour while cooking the sauce.
Are there any dietary restrictions I should consider?
Very much so! You can easily adapt Seafood Gratin to suit various dietary needs. For a dairy-free option, substitute the heavy cream and cheese with coconut milk and dairy-free cheese. Additionally, ensure that the seafood is safe for any allergies, especially shellfish allergies. Always check labels for any gluten-related products if you’re making it gluten-free.
Can I make Seafood Gratin ahead of time?
