🛒 Ingredients
- 2 cups cooked chicken breast, shredded or diced
- 2 cups fresh spinach, chopped
- 1 cup mushrooms, sliced
- 1/2 cup green onion cream cheese (or regular cream cheese + chopped green onions)
- 1/4 cup sour cream
- 1/2 cup grated mozzarella cheese
- 1/4 cup grated Parmesan cheese
- 1 tbsp olive oil
- 1 tsp garlic powder
- 1 tsp onion powder
- Salt & pepper, to taste
- 1/2 cup chicken broth
- 1 tbsp fresh parsley, chopped (for garnish)
👩🍳 Preparation Steps
1. Preheat the oven
Set your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. Cook the mushrooms
Heat olive oil in a large skillet over medium heat. Add the mushrooms and cook for 5–7 minutes, stirring occasionally, until they’re soft and golden. Remove and set aside.
3. Wilt the spinach
In the same skillet, add chopped spinach. Sauté for 2–3 minutes until wilted. Remove and set aside.
4. Mix the creamy base
In a bowl, whisk together cream cheese, sour cream, chicken broth, garlic powder, onion powder, salt, and pepper. Blend until creamy and smooth.
5. Layer the casserole
In your prepared baking dish, layer the cooked chicken, then the mushrooms, followed by the spinach. Pour the creamy sauce evenly over the entire dish, making sure all the layers are covered.
6. Add the cheese topping
Sprinkle the top with grated mozzarella and Parmesan cheese.
7. Bake to perfection
Bake for 20–25 minutes, or until the cheese is melted, golden, and bubbling, and the casserole is heated through.
8. Garnish & serve
Top with freshly chopped parsley before serving. Enjoy warm.
