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 Oven: Preheat your oven to 400°F (200°C) and lightly grease a 9×13-inch baking dish to prepare for the casserole.
  2. Prepare Chicken Cutlets: Cut each chicken breast horizontally in half to make four thin cutlets. Pound the thicker ends to ensure even thickness for uniform cooking.
  3. Make Marinade and Marinate Chicken: In a bowl, whisk together 1 tablespoon olive oil, minced garlic, Italian seasoning, salt, and black pepper. Toss the chicken cutlets in this marinade, then cover and refrigerate for 15 to 30 minutes to enhance flavor.
  4. Cook Spinach: Heat the remaining olive oil in a skillet over medium heat. Add the spinach and cook for 2 to 3 minutes until wilted. Remove from heat and set aside to cool slightly.
  5. Prepare Cheese Mixture: In a bowl, beat the softened cream cheese until smooth. Stir in the cooked spinach, 1/2 cup shredded mozzarella, and Parmesan cheese if using. Mix thoroughly until combined.
  6. (Optional) Sear the Chicken: For added flavor, sear the marinated chicken cutlets in a hot skillet for 1 to 2 minutes per side until lightly browned but not cooked through.
  7. Assemble Casserole: Arrange the chicken cutlets 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 preheated oven and bake for 20 to 30 minutes, or until the chicken reaches an internal temperature of 165°F (75°C) and the cheese on top is melted and lightly browned.
  9. Rest and Serve: Let the casserole rest for 5 minutes after baking to allow flavors to meld and juices to settle, then serve warm.

Notes

  • You can substitute fresh spinach with frozen spinach; just be sure to thaw and drain excess water before using.
  • For a richer flavor, searing the chicken before baking adds a nice texture but is optional.
  • If you prefer a lower-fat version, use reduced-fat cream cheese and mozzarella.
  • Leftovers can be stored in the refrigerator for up to 3 days and reheated in the oven or microwave.
  • Adding Parmesan cheese is optional but adds a nice sharpness and depth of flavor.
