How to Make Creamy Baked Fish on Potato Gratin
-
Preheat the oven to 180°C (350°F). This step is crucial for ensuring your dish cooks evenly, yielding that beautiful golden crust we’re after.
-
Prepare Potatoes: Cut your starchy potatoes into quarters, then slice them thinly. Soak them in water for about 10 minutes to prevent browning—this keeps them fresh and ready for the oven.
-
Make Crunchy Topping: In a bowl, mix together the panko breadcrumbs with extra virgin olive oil and stir in some grated Parmesan. This will provide that delicious crispy layer on top.
-
Sauté Leeks and Garlic: In an ovenproof skillet, melt the unsalted butter over medium heat. Add the leeks and garlic, cooking for about 3 minutes until fragrant and soft.
-
Sauté Potatoes: Add the soaked and drained potato slices to the skillet, seasoning with salt and pepper. Stir well and cook for about 6 minutes until they’re just tender.
-
Reduce Wine and Stock: Pour the dry white wine over the sautéed potatoes, allowing it to simmer until mostly evaporated (about 2-3 minutes). Then add the vegetable stock and simmer for another 1.5 minutes until reduced by half.
-
Layer Fish: Turn off the heat and carefully place the white fish fillets on top of the potatoes. Pour the heavy cream over the fish to ensure it stays moist during baking.
-
Top with Panko: Evenly sprinkle the prepared panko mixture over the fish and potatoes, covering everything for that ideal crunch.
-
Bake: Transfer the skillet to the preheated oven and bake for 30 minutes, or until the fish is cooked through and tender.
-
Broil: For an extra crispy finish, place the dish under the broiler for an additional 4 minutes until the topping is golden brown.
-
Rest: Allow the dish to rest for about 5 minutes before serving. This helps everything combine beautifully and enhances the flavors.
Optional: Garnish with fresh herbs like parsley or chives before serving for a pop of color.

Expert Tips for Creamy Baked Fish on Potato Gratin
-
Choose the Right Fish: Opt for thicker cuts of white fish like barramundi or snapper to ensure they remain moist during cooking. Avoid thin fillets that may dry out.
-
Don’t Overcrowd the Pan: Prevent steaming by evenly distributing the potato slices in the pan. This ensures proper cooking and lets the panko topping get wonderfully crispy.
-
Rest Before Serving: Let the dish rest for about 5 minutes after baking. This allows the fish to reabsorb juices and enhances the flavor of every serving.
-
Depth of Flavor: For a richer taste, don’t skip the step of reducing the wine and stock. This concentrates the flavors and elevates your creamy baked fish on potato gratin.
-
Customize to Taste: Feel free to include seasonal vegetables like spinach or peas in the dish for added nutrition. Mixing in different cheeses can also elevate the flavor profile!

Creamy Baked Fish on Potato Gratin Recipe FAQs
What type of fish is best for this recipe?
Absolutely! For the best results in your creamy baked fish on potato gratin, I recommend using white fish fillets like barramundi, snapper, or tilapia. They should be about 2cm (0.8″) thick to ensure they cook evenly and remain moist. Thinner cuts can overcook easily and lose tenderness.
How do I choose the right potatoes for the gratin?
Very! Starchy potatoes such as Russet, Sebago, or Maris Piper are ideal for a creamy gratin texture. Make sure to peel and slice them thinly for even cooking. If your potatoes feel firm and have a smooth skin, they’re good to go!
How can I store leftovers?
Absolutely! Leftovers can be stored in an airtight container in the fridge for up to 3 days. When reheating, cover the dish with foil to keep the top from burning while ensuring the inside heats through nicely. It’s a comforting meal to enjoy more than once!
Can I freeze this dish?
No, this dish is not suitable for freezing. The creamy texture of both the fish and potatoes can suffer upon thawing, leading to a less enjoyable experience. It’s best enjoyed fresh or as leftovers within a few days!
What if my potatoes aren’t crispy after baking?
Ah, the dreaded soggy potato! If you find your potatoes haven’t crisped up properly, make sure they’re not overcrowded in the pan before baking. Also, broiling for a few extra minutes at the end can help achieve that perfect golden-top texture. Just keep an eye on them so they don’t burn—trust me, it’s worth it!
Are there any dietary considerations for this recipe?
Very! Always be cautious if there’s a risk of allergies. This dish contains dairy due to the heavy cream and unsalted butter, which might not suit lactose-intolerant individuals or those with dairy allergies. For a non-alcoholic version, substituting white wine with vegetable stock works beautifully, making it accessible for everyone at your dinner table. Enjoy the flavors freely!
