How to Make Creamy Baked Fish on Potato Gratin

Now that you have all your ingredients ready, let’s dive into the steps to create this comforting dish. Follow along, and soon you’ll have a delicious meal that’s sure to impress!

Step 1: Preheat and Prepare

Start by preheating your oven to 375°F (190°C). This ensures your dish cooks evenly. While the oven warms up, grab a 9×13-inch baking dish and grease it with cooking spray or butter. This will help prevent sticking and make cleanup a breeze.

Step 2: Sauté the Onions

In a large skillet, heat 2 tablespoons of olive oil over medium heat. Once hot, add the thinly sliced onions. Sauté them for about 5 minutes, stirring occasionally, until they become soft and translucent. This step is crucial; it brings out the sweetness of the onions, adding depth to your dish.

Step 3: Mix the Cream Mixture

In a large bowl, combine 1 cup of heavy cream, 1 cup of milk, 1 teaspoon of garlic powder, 1 teaspoon of salt, 1/2 teaspoon of black pepper, and 1/2 teaspoon of dried thyme. Whisk everything together until well combined. This creamy mixture is what makes the dish so indulgent and flavorful.

Step 4: Layer the Potatoes

Now it’s time to build your gratin! Start by layering half of the sliced potatoes in the bottom of your prepared baking dish. Spread the sautéed onions evenly over the potatoes. Then, pour half of the cream mixture over this layer. Repeat with the remaining potato slices and the rest of the cream mixture. Gently press down to ensure the potatoes are submerged in the creamy goodness.

Step 5: Bake the Potatoes

Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 45 minutes. This initial baking allows the potatoes to soften and absorb all those delicious flavors. The foil helps trap steam, ensuring everything cooks evenly.

Step 6: Add the Fish and Cheese

After 45 minutes, carefully remove the foil. Season your fish fillets with salt and pepper, then place them on top of the baked potatoes. Sprinkle 1 cup of shredded cheddar cheese over the fish. This cheesy layer will create a delightful crust as it bakes.

Step 7: Final Bake

Return the dish to the oven, uncovered, and bake for an additional 20-25 minutes. You’ll know it’s done when the fish is cooked through and the cheese is bubbly and golden. The aroma wafting through your kitchen will be irresistible!

Tips for Success

• Use a mandoline slicer for perfectly even potato slices.
• Let the dish rest for a few minutes after baking; it helps the layers set.
• Experiment with different cheeses like Gruyère or mozzarella for a unique twist.
• For added flavor, consider marinating the fish in lemon juice before baking.
• Don’t skip the fresh parsley; it brightens the dish beautifully!

Equipment Needed

• Baking Dish: A 9×13-inch dish is ideal, but any oven-safe dish will work.
• Skillet: A large skillet for sautéing onions; a non-stick option makes cleanup easier.
• Whisk: Essential for mixing the cream mixture; a fork can work in a pinch.
• Mandoline Slicer: For even potato slices; a sharp knife will do if you’re careful.

Variations

• Vegetable Boost: Add layers of spinach, broccoli, or zucchini for extra nutrition and color.
• Herb Infusion: Experiment with fresh herbs like dill or basil for a fragrant twist.
• Spicy Kick: Incorporate a pinch of red pepper flakes or a dash of hot sauce for some heat.
• Seafood Medley: Mix in shrimp or scallops along with the fish for a seafood extravaganza.
• Gluten-Free Option: Ensure all ingredients are certified gluten-free, especially the cheese.

Serving Suggestions

• Fresh Salad: Pair with a crisp green salad dressed in a light vinaigrette for a refreshing contrast.
• Crusty Bread: Serve with a warm, crusty baguette to soak up the creamy sauce.
• White Wine: A chilled glass of Sauvignon Blanc complements the fish beautifully.
• Garnish: Add lemon wedges on the side for a zesty finish.
