Ingredients

Scale

Chicken Marinade

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

Spinach Mixture

  • 1 tablespoon olive oil
  • 2 cups fresh spinach
  • 8 ounces cream cheese, softened
  • 1/2 cup shredded mozzarella cheese
  • 1/2 cup Parmesan cheese (optional)

Topping

  • 1/2 cup shredded mozzarella cheese

Instructions

  1. Preheat and Prepare: Preheat your oven to 400°F (200°C) and lightly grease a 9×13-inch baking dish to prevent sticking.
  2. Prepare Chicken: Cut each chicken breast horizontally in half to create four thin cutlets. Pound the thicker ends to ensure even thickness for uniform cooking.
  3. 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, cover, and refrigerate for 15-30 minutes to infuse flavors.
  4. Cook Spinach: Heat the remaining 1 tablespoon 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. Mix Cheese and Spinach: In a mixing bowl, beat the softened cream cheese until smooth. Stir in the cooked spinach, 1/2 cup shredded mozzarella, and Parmesan cheese if using, creating a creamy spinach mixture.
  6. Sear Chicken (Optional): For added flavor, sear the marinated chicken cutlets in a hot skillet for 1-2 minutes per side until lightly browned but not fully cooked.
  7. Assemble Casserole: Arrange the chicken cutlets evenly in the greased baking dish. Spread the cream cheese and spinach mixture over the chicken. Sprinkle the remaining 1/2 cup shredded mozzarella cheese on top.
  8. Bake: Place the baking dish in the preheated oven and bake for 20-30 minutes, or until the chicken reaches an internal temperature of 165°F (75°C) and the cheese topping 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 set.

Notes

  • For a stronger flavor, you can increase the garlic amount to 4 cloves.
  • Pounding the chicken ensures even cooking and tenderness.
  • Searing the chicken before baking is optional but adds a nice caramelized flavor and texture.
  • Feel free to substitute spinach with kale or Swiss chard if preferred.
  • Parmesan cheese is optional but adds an extra layer of richness.
  • Make sure the chicken reaches a safe internal temperature of 165°F (75°C) before serving.
