Ingredients

Scale

Chicken

  • 2 large boneless, skinless chicken breasts
  • 2 tablespoons olive oil, divided
  • 3 cloves garlic, minced
  • 1 tablespoon Italian seasoning
  • 1/4 teaspoon salt
  • 1/2 teaspoon black pepper

Spinach and Cheese Mixture

  • 2 cups fresh spinach
  • 8 ounces cream cheese, softened
  • 1 cup shredded mozzarella cheese, divided
  • 1/2 cup Parmesan cheese, optional

Instructions

  1. Preheat Oven and Prepare Dish: Preheat your oven to 400°F (200°C) and lightly grease a 9×13-inch baking dish to prevent sticking.
  2. Slice and Pound Chicken: Cut each chicken breast in half horizontally to create four thin cutlets, pounding the thicker ends to ensure even thickness for uniform cooking.
  3. Marinate Chicken: In a bowl, whisk together 1 tablespoon of olive oil, minced garlic, Italian seasoning, salt, and black pepper. Toss the chicken cutlets in this marinade, cover, and refrigerate for 15-30 minutes to infuse flavor.
  4. Cook Spinach: Heat the remaining tablespoon of olive oil in a skillet over medium heat. Add fresh spinach and cook for 2-3 minutes until wilted. Remove from heat and set aside.
  5. Prepare Cheese Mixture: Beat the softened cream cheese in a bowl until smooth, then stir in the cooked spinach and 1/2 cup of shredded mozzarella cheese. Add Parmesan cheese if using, mixing well.
  6. Optional Sear: For added flavor, sear the marinated chicken cutlets in a hot skillet for 1-2 minutes per side until lightly browned, but do not fully cook.
  7. Assemble Casserole: Arrange the chicken pieces evenly in the greased baking dish. Spread the cream cheese and spinach mixture evenly over the chicken, then sprinkle the remaining 1/2 cup mozzarella cheese on top.
  8. Bake: Place the baking dish in the oven and bake for 20-30 minutes, or until the chicken reaches an internal temperature of 165°F (75°C) and the cheese is melted and lightly browned.
  9. Rest and Serve: Remove the casserole from the oven and let it rest for 5 minutes before serving to allow flavors to meld and juices to settle.

Notes

  • For extra flavor, searing the chicken before baking is recommended but can be skipped if short on time.
  • If Parmesan cheese is not available, you can omit it; the dish will still be creamy and tasty.
  • Use fresh spinach for best texture and flavor, but frozen spinach can be substituted if properly thawed and drained.
  • Make sure not to overcook the chicken during the searing step since it will finish cooking in the oven.
  • Serve with a side of rice, pasta, or crusty bread for a complete meal.
