Ingredients

Scale

Chicken and Marinade

  • 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 and prepare baking dish: Preheat your oven to 400°F (200°C) and lightly grease a 9×13-inch baking dish to prevent sticking.
  2. Prepare chicken cutlets: Cut each chicken breast in half horizontally to create four thin cutlets. Pound the thicker ends to ensure even thickness for consistent cooking.
  3. Marinate the 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 the spinach: In a skillet, heat the remaining olive oil over medium heat. Add the fresh spinach and cook for 2-3 minutes until wilted. Remove from heat and set aside.
  5. Mix cream cheese filling: Beat the softened cream cheese in a bowl until smooth. Stir in the cooked spinach and 1/2 cup of shredded mozzarella cheese. If using, add the Parmesan cheese as well and mix thoroughly.
  6. Optional sear chicken: For added flavor, heat a skillet over medium-high and sear the marinated chicken cutlets for 1-2 minutes per side until lightly browned. This step adds a deeper flavor but is optional.
  7. Assemble casserole: Arrange the chicken cutlets in the greased baking dish in a single layer. Spread the cream cheese and spinach mixture evenly over the chicken, then top with the remaining 1/2 cup mozzarella cheese.
  8. Bake until cooked: Place the casserole in the preheated oven and bake for 20-30 minutes until the chicken reaches an internal temperature of 165°F (75°C) and the cheese is melted, bubbly, and lightly browned on top.
  9. Rest and serve: Remove the casserole from the oven and let it rest for 5 minutes to allow flavors to settle before serving warm.

Notes

  • Ensure chicken cutlets are pounded evenly for uniform cooking.
  • Seared chicken adds extra flavor but can be skipped for a quicker prep.
  • Parmesan cheese is optional but enhances the cheesy flavor profile.
  • Use fresh spinach for best texture; frozen spinach can be substituted but should be thoroughly drained.
  • You can prepare the casserole a day ahead and refrigerate before baking.
  • Check chicken temperature with a meat thermometer to guarantee doneness.
