Ingredients

For the Spinach Casserole

• 4 cups fresh spinach, chopped
• 1 cup ricotta cheese
• 1 cup grated Parmesan cheese
• 2 large eggs
• 1/2 cup heavy cream
• 1 teaspoon garlic powder
• 1 teaspoon onion powder
• Salt and black pepper, to taste
• 1/2 teaspoon red pepper flakes, optional

For the Crispy Topping

• 1 cup breadcrumbs
• 2 tablespoons olive oil
• 2 tablespoons grated Parmesan cheese, optional

How to Make Spinach Parmesan Casserole

1. Prepare the Oven

Preheat the oven to 375°F (190°C). Lightly grease a medium-sized baking dish and set it aside.

2. Prepare the Spinach

Place the chopped spinach in a large skillet over medium heat. Cook for 2–3 minutes, stirring occasionally, until the spinach has wilted.

Allow it to cool slightly, then squeeze out as much excess moisture as possible. Removing the extra liquid helps prevent the casserole from becoming watery.

3. Make the Creamy Filling

In a large bowl, combine the ricotta, Parmesan, eggs, heavy cream, garlic powder, onion powder, salt, black pepper and red pepper flakes if using.

Stir until the mixture is smooth and evenly combined.

4. Add the Spinach

Fold the cooked spinach into the cheese mixture. Stir gently until the spinach is evenly distributed throughout the filling.

5. Transfer to the Baking Dish

Spread the spinach and Parmesan mixture evenly into the prepared baking dish. Smooth the surface with the back of a spoon.

6. Prepare the Crispy Topping

In a small bowl, combine the breadcrumbs, olive oil and optional Parmesan cheese.

Mix until the breadcrumbs are lightly coated with the oil.

7. Add the Crispy Topping

Sprinkle the breadcrumb mixture evenly over the spinach and Parmesan filling, covering the surface as evenly as possible.

8. Bake

Bake uncovered for 30–35 minutes, until the casserole is hot and set in the centre and the breadcrumb topping is golden and crisp.

9. Rest and Serve

Allow the casserole to rest for 5–10 minutes before serving. Finish with freshly cracked black pepper and a little extra Parmesan if desired.

Tips for the Best Spinach Parmesan Casserole

• Remove excess spinach moisture: Squeeze the cooked spinach thoroughly after it cools slightly.
• Don’t skip the resting time: Letting the casserole sit briefly helps the centre settle before serving.
• Spread the breadcrumbs evenly: This gives you a consistent golden, crispy topping.
• Watch the final minutes: The breadcrumb topping can brown quickly towards the end of baking.
• Add chilli to taste: Red pepper flakes are optional, so leave them out for a milder casserole.

What to Serve with Spinach Parmesan Casserole

This creamy spinach casserole works beautifully as a side dish. Serve it with roasted chicken, baked fish, grilled meat or roasted vegetables.

It can also be served as part of a larger vegetarian meal alongside a fresh green salad, crusty bread or other vegetable dishes.

Frequently Asked Questions

How do I know when the casserole is ready?

The centre should be set and the breadcrumb topping should be golden and crisp after approximately 30–35 minutes of baking.

Can I make this casserole less spicy?

Absolutely. Simply leave out the red pepper flakes for a milder version.
