Description

A creamy and flavorful baked chicken dish loaded with tender spinach, savory mushrooms, and melted cheese. This comforting casserole is perfect for an easy weeknight dinner or meal prep favorite.


Ingredients

  • 1 1/2 lbs boneless, skinless chicken breasts (about 34 pieces)
  • 2 tbsp olive oil
  • 2 cups fresh spinach leaves
  • 8 oz mushrooms, sliced
  • 1 small onion, finely chopped
  • 3 cloves garlic, minced
  • 1 cup heavy cream
  • 1/2 cup chicken broth
  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • 1 tbsp butter
  • 1 tsp Italian seasoning
  • 1/2 tsp paprika
  • Salt and black pepper to taste
  • 2 tbsp chopped parsley (for garnish)


Instructions

  1. Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
  2. Season chicken breasts with salt, pepper, and paprika on both sides.
  3. In a large skillet, heat olive oil over medium heat. Sear chicken for 3–4 minutes per side until lightly golden. Remove and set aside.
  4. In the same skillet, melt butter and add onions and mushrooms. Sauté for 5–6 minutes until softened and browned.
  5. Add minced garlic and cook for 30 seconds until fragrant.
  6. Stir in chicken broth and heavy cream, then add Italian seasoning and Parmesan cheese. Simmer for 3–4 minutes until sauce slightly thickens.
  7. Stir in spinach and cook until wilted, about 1–2 minutes.
  8. Pour half of the creamy mixture into the prepared baking dish. Arrange seared chicken breasts on top, then pour the remaining sauce over the chicken.
  9. Sprinkle mozzarella cheese evenly over the top.
  10. Bake uncovered for 20–25 minutes, or until the chicken is cooked through (internal temp 165°F / 74°C) and the cheese is bubbly and golden.
  11. Garnish with chopped parsley before serving.

Notes

  • Use baby spinach for a tender texture.
  • Substitute half-and-half for a lighter sauce if desired.
  • This dish pairs beautifully with pasta, rice, or a green salad.
  • Make ahead by assembling the casserole and refrigerating up to 24 hours before baking.
