Step-by-Step Instructions

Now, let’s get cooking! Follow these detailed instructions to create your own delicious Crunchy Cheesy Fish and Spinach Casserole.

**Step 1: Prepare the Fish**

1. Preheat oven to 375°F (190°C).
2. Lightly grease a 9×13 inch baking dish.
3. In a bowl, gently toss the fish pieces with 1 tablespoon of olive oil, salt, and pepper. This ensures the fish is seasoned evenly.

**Step 2: Sauté the Vegetables**

1. Heat the remaining 1 tablespoon of olive oil in a large skillet over medium heat.
2. Add the chopped onion and cook until softened, about 5-7 minutes. Stir occasionally to prevent burning.
3. Add the minced garlic and cook for another minute, until fragrant.
4. Add the spinach to the skillet and cook until wilted, about 2-3 minutes. If using frozen spinach, make sure it is thoroughly drained before adding it to the skillet. Excess water will make the casserole soggy.
5. Remove the skillet from the heat and set aside.

**Step 3: Make the Cheese Sauce**

1. In a medium saucepan, melt the butter over medium heat.
2. Whisk in the flour and cook for 1-2 minutes, stirring constantly. This creates a roux, which will thicken the sauce.
3. Gradually whisk in the milk, ensuring there are no lumps. Continue whisking until the sauce starts to thicken.
4. Bring the sauce to a simmer, then reduce the heat to low.
5. Add the softened cream cheese and stir until melted and smooth. This adds richness and creaminess to the sauce.
6. Stir in 1 1/2 cups of the shredded cheese, salt, and pepper. Continue stirring until the cheese is melted and the sauce is smooth and creamy. Taste and adjust seasonings as needed. A pinch of nutmeg can add a warm, subtle flavor. Some people also like a touch of garlic powder or onion powder in the sauce.

**Step 4: Assemble the Casserole**

1. Spread the spinach mixture evenly over the bottom of the prepared baking dish.
2. Arrange the fish pieces over the spinach. Try to distribute the fish evenly so that each serving has a good portion.
3. Pour the cheese sauce over the fish and spinach, ensuring everything is evenly coated.

**Step 5: Prepare the Crunchy Topping**

1. In a small bowl, combine the panko bread crumbs, Parmesan cheese, and remaining 1/2 cup of shredded cheese.
2. Sprinkle the bread crumb mixture evenly over the cheese sauce. This will create a golden brown and crunchy topping.

**Step 6: Bake the Casserole**

1. Bake in the preheated oven for 25-30 minutes, or until the topping is golden brown and the fish is cooked through and flakes easily with a fork. The internal temperature of the fish should reach 145°F (63°C).

**Step 7: Let it Rest and Serve**

1. Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This allows the sauce to thicken slightly and prevents it from being too runny.
2. Serve hot, garnished with lemon wedges, if desired. A side salad or steamed vegetables would be a perfect accompaniment.

Tips for Success

* **Use fresh, high-quality fish:** The quality of the fish will greatly impact the taste of the casserole. Choose fillets that are firm, moist, and have a fresh, clean smell.
* **Don’t overcook the fish:** Overcooked fish will be dry and rubbery. Cook the fish just until it flakes easily with a fork.
* **Drain the spinach thoroughly:** Excess water from the spinach will make the casserole soggy. Squeeze out as much water as possible before adding it to the skillet.
* **Use a good quality cheese:** The cheese is a key component of the sauce, so use a good quality cheese that melts well.
* **Adjust the seasonings to your liking:** Taste the cheese sauce and adjust the seasonings to your liking. Don’t be afraid to experiment with different spices and herbs.
* **Prevent the topping from burning:** If the topping starts to brown too quickly, cover the casserole with foil for the last 10-15 minutes of baking.
* **Make it ahead of time:** You can assemble the casserole ahead of time and store it in the refrigerator for up to 24 hours. Add the breadcrumb topping just before baking.
* **Reheat leftovers:** Leftover casserole can be reheated in the oven or microwave. To reheat in the oven, cover the casserole with foil and bake at 350°F (175°C) until heated through.

Variations and Substitutions

* **Fish:** You can use different types of fish, such as salmon, tuna, or shrimp. Adjust the cooking time accordingly.
* **Vegetables:** Add other vegetables to the casserole, such as mushrooms, bell peppers, or broccoli.
* **Cheese:** Use different types of cheese, such as Gruyere, Swiss, or pepper jack.
* **Sauce:** Add a splash of white wine or lemon juice to the cheese sauce for extra flavor. For a richer sauce, use heavy cream instead of milk.
* **Topping:** Use crushed crackers, potato chips, or cornflakes instead of bread crumbs for the topping. Add some chopped nuts or seeds to the topping for extra crunch and flavor.
* **Gluten-Free:** To make this casserole gluten-free, use gluten-free flour for the roux and gluten-free bread crumbs for the topping.
* **Dairy-Free:** For a dairy-free version, use dairy-free butter, milk, cream cheese, and shredded cheese. You can also omit the cheese sauce and use a white sauce made with vegetable broth and cornstarch.
* **Spicy:** Add a pinch of red pepper flakes or a dash of hot sauce to the cheese sauce for a spicy kick.
