This hearty spinach and fish bake has been a lifesaver for busy weeknights in my home. With just a handful of ingredients and minimal effort, it delivers a nutritious meal that brings comfort to the table without hours in the kitchen.

I discovered this recipe during a particularly hectic week when my sister-in-law was visiting. She couldn't believe how quickly it came together, and now it's become her go-to dish for introducing seafood to her picky eaters at home.

Ingredients

  • Frozen chopped spinach: this is the foundation of the dish providing nutrients and a tender base
  • Sharp cheddar cheese: creates a creamy richness that complements the mild fish perfectly
  • Dry bread crumbs: adds essential texture and helps bind everything together
  • Egg: works as the crucial binder that keeps the spinach layer cohesive
  • Cod fillets: mild white fish that flakes beautifully, look for thick pieces with firm texture
  • Salt and pepper: simple seasoning that enhances the natural flavors

How To Make Aunt Carol's Spinach and Fish Bake

Prepare the oven:
Set your oven to 325°F. This gentle temperature ensures the fish cooks evenly without drying out while giving the cheese enough time to melt beautifully into the spinach mixture.
Create the spinach base:
Thoroughly mix the thawed and squeezed spinach with half cup of sharp cheddar cheese, five tablespoons of bread crumbs, and the beaten egg until well combined. Press this mixture evenly across the bottom of a small baking dish, creating a flavorful bed for the fish.
Layer the fish:
Arrange the cod fillets directly on top of the spinach mixture, making sure they fit comfortably without overlapping. Season generously with salt and pepper to enhance the delicate flavor of the fish.
Add the topping:
Sprinkle the remaining cheddar cheese and bread crumbs over the fish, creating a golden crust that will become irresistibly crispy during baking.
Bake to perfection:
Cover the dish with foil and bake for 20 minutes, or until the fish flakes easily with a fork. The covering helps trap moisture while the fish cooks through completely.

The first time I made this for my family, my four-year-old nephew picked up his fork and proclaimed it was "fish treasure hidden under cheese gold." That moment convinced me that this dish had special powers to make vegetables exciting even for the pickiest eaters.

Flavor Variations

While the original recipe calls for cod, almost any white fish works wonderfully. I've made successful versions with tilapia for a budget-friendly option, halibut for special occasions, and even haddock when it was on sale. Each fish brings its own texture but maintains the delicate flavor profile that pairs so well with the creamy spinach base.

Make-Ahead Tips

This recipe shines as a meal prep champion. You can prepare the spinach mixture up to two days ahead and keep it refrigerated. When ready to cook, simply layer with fresh fish and toppings, then bake. The prepped spinach base actually develops more flavor after sitting, making this a rare dish that benefits from advance preparation.

The versatility of this dish makes it perfect for various serving styles. For a complete meal, pair it with roasted cherry tomatoes and a side of quinoa or brown rice to soak up the flavorful juices. For a lighter option, serve alongside a crisp green salad dressed with lemon vinaigrette. The mild flavors also complement a side of garlic bread for a more indulgent dinner experience.
