Ingredients

• 500 grams fresh spinach
• 250 grams mushrooms
• 2 tablespoons butter
• 2 garlic cloves
• 2 tablespoons all-purpose flour
• 1.5 cups milk
• 120 grams cream cheese
• 1 cup shredded mozzarella cheese
• 0.5 cup parmesan cheese
• 0.5 cup breadcrumbs
• 1 tablespoon olive oil
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 0.25 teaspoon nutmeg (optional)

Directions

Step 1

Preheat the oven to 190°C (375°F) and grease a medium-sized casserole dish with a little butter or olive oil.

Step 2

Wash the spinach thoroughly and roughly chop it. Slice the mushrooms thinly. Mince the garlic cloves.

Step 3

Heat a large skillet over medium heat and add 1 tablespoon of butter. Once melted, add the garlic and sauté for 1 minute until fragrant.

Step 4

Add the mushrooms to the skillet and cook for 5–7 minutes, stirring occasionally, until softened and lightly browned. Set the mushrooms aside in a separate bowl.

Step 5

Using the same skillet, add another tablespoon of butter. Once melted, sprinkle the flour over the butter and whisk continuously to make a roux. Cook the roux for 1–2 minutes until light golden.

Step 6

Slowly pour in the milk while whisking to prevent lumps. Continue cooking and whisking for 3–4 minutes until the mixture thickens to a creamy consistency.

Step 7

Stir in the cream cheese and mix until fully melted and smooth. Season with salt, black pepper, and nutmeg (if using).

Step 8

Add the chopped spinach to the skillet and cook for 2–3 minutes, stirring frequently, until wilted. Return the cooked mushrooms to the skillet and fold them into the creamy mixture.

Step 9

Transfer the spinach and mushroom mixture into the prepared casserole dish. Spread it out evenly.

Step 10

Sprinkle the shredded mozzarella cheese and parmesan cheese evenly over the top.

Step 11

In a small bowl, mix the breadcrumbs with olive oil to lightly moisten them. Sprinkle the breadcrumb mixture over the cheese layer.

Step 12

Bake the casserole in the preheated oven for 20–25 minutes, or until the top is golden brown and bubbly.

Step 13

Remove from the oven and let it rest for 5 minutes before serving. Enjoy your Spinach and Mushroom Casserole!
