A comforting casserole featuring tender chicken, earthy mushrooms, and nutrient-packed spinach in a luscious creamy sauce. Perfect for weeknight dinners or potlucks.

Ingredients

Scale
  • 23 cups cooked chicken breast, shredded or diced
  • 4 cups fresh spinach, roughly chopped
  • 2 cups sliced mushrooms
  • 2 tablespoons unsalted butter
  • 2 cloves garlic, minced
  • 1 1/2 cups whole milk
  • 1 cup low-sodium chicken broth
  • 2 tablespoons all-purpose flour
  • 1 cup shredded mozzarella cheese
  • Salt, pepper, and a pinch of nutmeg

Instructions

  1. Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish lightly with oil or butter.
  2. Heat the butter in a large skillet over medium heat. Add the garlic and sauté for 30 seconds until fragrant. Add the mushrooms and cook for 5-7 minutes until softened. Add the spinach and cook for another 2-3 minutes until wilted.
  3. Sprinkle the flour over the cooked vegetables and stir well. Gradually whisk in the milk and chicken broth to form a smooth sauce. Season with salt, pepper, and a pinch of nutmeg. Cook for 3-5 minutes, stirring constantly, until the sauce thickens.
  4. In a large bowl, mix the shredded chicken with the cooked spinach and mushrooms. Pour the creamy sauce over the mixture and stir until everything is well coated.
  5. Transfer the mixture to the prepared baking dish. Spread it out evenly and sprinkle mozzarella cheese on top.
  6. Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and golden brown.
  7. Let the casserole cool for 5 minutes before serving. Enjoy warm!

Notes

Use pre-cooked chicken for convenience. Don’t skip sautéing the mushrooms and spinach to enhance flavor. Freshly shredded cheese melts better than pre-shredded cheese.
