Ingredients

Instructions

1. Prepare the Casserole Dish

Begin by preheating your oven to 350°F (175°C). This temperature ensures even baking and prevents the fish from drying out. While the oven warms, take your 1½-quart casserole dish and generously coat it with non-stick cooking spray or a light layer of butter to prevent sticking. Proper preparation of the dish is crucial to maintain the integrity of the bake and facilitate easy cleanup afterward.

2. Layer the Spinach

Once the casserole dish is ready, spread the frozen chopped spinach evenly across the bottom. If the spinach is frozen, there is no need to thaw it beforehand; just ensure it is evenly distributed to create a flavorful base. If you prefer a more textured spinach layer, gently pat it down with the back of a spoon or spatula. This layer serves as a nutritious foundation, providing fiber, iron, and a subtle earthy flavor that complements the delicate flounder fillets perfectly. For an extra burst of flavor, you could sprinkle a pinch of garlic powder or nutmeg over the spinach before adding the fish.

3. Arrange the Flounder

Next, carefully place the flounder fillets over the spinach layer. Arrange them in a single layer, spacing them evenly to ensure uniform cooking. If the fillets are thick, consider gently pressing them down to ensure they are in contact with the spinach and sauce layers. Season each fillet with salt and freshly ground black pepper to taste, ensuring the seasoning is evenly distributed. This step is vital as it enhances the natural sweetness of the fish and brings out the flavors of the other ingredients. For an added flavor dimension, you can sprinkle a dash of paprika or lemon zest over the fillets before baking.

4. Prepare the Sauce

In a mixing bowl, combine the dry sherry and flour. Whisk or stir until the flour is fully incorporated, forming a smooth paste. The sherry not only adds depth and a subtle acidity but also helps to infuse the fish with a delicate aroma. After mixing, add the cream of mushroom soup to the bowl and stir thoroughly until you achieve a smooth, consistent sauce. This creamy mixture will envelop the fish, keeping it moist and tender during baking. For a gluten-free variation, substitute the all-purpose flour with cornstarch or a gluten-free flour blend. For a richer flavor, consider adding a splash of lemon juice or a teaspoon of Dijon mustard to the sauce.

5. Assemble the Dish

Pour the prepared sauce evenly over the flounder fillets, ensuring each piece is coated thoroughly. The sauce should seep into the layers, creating a moist environment that encourages delicate flounder to remain tender. Once the sauce is distributed, sprinkle the grated Parmesan cheese evenly over the top. The cheese will melt during baking, forming a golden, bubbly crust that adds a savory richness to the dish. If you like a more intense cheesy flavor, you can mix additional Parmesan with other grated cheeses like Gruyère or mozzarella.

6. Add Butter and Bake

Finally, distribute the bits of unsalted butter over the cheese layer. The butter will melt and seep into the dish, adding richness and helping develop a beautiful golden topping. Place the casserole dish on the middle rack of your preheated oven and bake for 25 minutes. During this time, the fish will cook through, the sauce will thicken slightly, and the cheese will form a bubbling, golden crust. Keep an eye on the dish during the last few minutes; if the cheese is browning too fast, tent the dish with aluminum foil to prevent burning while ensuring thorough cooking.

7. Serve and Enjoy

Once baked, remove the casserole from the oven and let it rest for about 5 minutes. This pause allows the flavors to settle and the sauce to thicken slightly, making it easier to serve. Use a spatula or large serving spoon to transfer portions onto individual plates. The dish pairs beautifully with a fresh side salad, steamed vegetables, or crusty artisan bread to soak up the savory sauce. For a more complete meal, consider serving with a glass of chilled white wine or sparkling water infused with lemon.

Preparation Tips

• Use Fresh Fish: For the best flavor and texture, opt for fresh flounder fillets if available. If using frozen, ensure they are properly thawed and patted dry to prevent excess moisture from diluting the sauce.
• Season Generously: Don’t be shy with salt and pepper; these seasonings are essential to enhance the natural flavors of the fish and greens.
• Customize the Sauce: Feel free to add herbs like dill or parsley to the sauce for an herbaceous note. A splash of lemon juice can also brighten the dish.
• Cheese Variations: Experiment with different cheeses such as Gruyère, Fontina, or a blend to achieve varied flavor profiles.
• Gluten-Free Options: Substitute the flour and cream of mushroom soup with gluten-free alternatives to accommodate dietary restrictions.

Save and Store

This dish is best enjoyed fresh out of the oven, but leftovers can be stored in an airtight container in the refrigerator for up to 2 days.

For best results, consume within 1 month of freezing.

FAQ

Can I use fresh spinach instead of frozen?

Yes, but you should blanch the fresh spinach briefly and drain excess water thoroughly before adding it to the casserole. Frozen spinach is more convenient and has a softer texture that integrates well with the sauce.

Can I substitute other fish?

Absolutely. Cod, haddock, or sole can be used as alternatives to flounder. Adjust cooking times based on the thickness of the fillets to prevent overcooking.

Is this dish suitable for a low-carb diet?

Yes. To make it more low-carb, reduce or omit the flour and consider using a cheese or nut-based crust instead of the breadcrumb or cheese topping.

Can I make this ahead?

Yes. Assemble the dish up to the baking stage, cover tightly, and refrigerate for up to 24 hours. Bake when ready, adding a few extra minutes if cold from the fridge.
