Essential Ingredients for the Gratin
To make this delicious gratin, you’ll need fresh cod fillets, spinach, parmesan cheese, and a few pantry staples. Each ingredient plays a crucial role in achieving the perfect balance of flavors and textures. The parmesan adds a nutty, savory element, while the spinach brings a hint of earthiness that rounds out the dish.

Step-by-Step Instructions
Preparing the Cod and Spinach
Begin by ensuring your cod fillets are fresh and free of bones. Season them lightly with salt and pepper. SautƩ the spinach until just wilted, then set aside. This step ensures the spinach retains its vibrant color and nutrients, adding a fresh contrast to the creamy gratin.
Assembling the Gratin
Layer the cod and sautƩed spinach in a baking dish, and generously sprinkle parmesan cheese over the top. This layering technique ensures each bite is packed with flavor. The cheese will melt and form a golden crust during baking, which is a hallmark of a perfect gratin.
Baking to Perfection
Preheat your oven to 375°F (190°C) and bake the gratin until the top is bubbly and golden brown. This should take about 25-30 minutes. The key to achieving the perfect bake is to ensure the cheese is melted and slightly crisped at the edges, giving you that irresistible crunch.

Pro Tips
Mastering the perfect gratin is an art, and these tips will help you achieve that golden crust every time.
- Use freshly grated parmesan for the best flavor and melting quality.
- Ensure your cod is dry before cooking to prevent excess moisture in the gratin.
- Add breadcrumbs to the topping for extra crunch.
- Let the gratin rest for a few minutes before serving to allow the flavors to meld and the cheese to set.
The most crucial tip is to avoid overcooking the fish. Keep a close eye on the gratin during the last few minutes of baking. For more creamy dishes, try our Creamy Mushroom Spinach Ravioli Bake.
