Ingredients
  

Ingredients
  • 2 large boneless, skinless chicken breasts (about 1.5 lbs), cut into thin cutlets
  • 2 tablespoons olive oil, divided
  • 3 cloves garlic, minced
  • 1 tablespoon Italian seasoning
  • 1/4 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 cups fresh spinach
  • 8 ounces cream cheese, softened to room temperature
  • 1 cup shredded mozzarella cheese, divided
  • 1/2 cup Parmesan cheese, grated (optional, but recommended)

Equipment

  • 9x13 inch baking dish
  • medium bowl
  • Skillet
  • Meat mallet or rolling pin
  • Instant-read meat thermometer

Method
 

Instructions
  1. Prepare Your Oven and Dish: First things first, preheat your oven to 400°F (200°C). Grab a 9×13-inch baking dish and give it a light greasing to prevent sticking.
  2. Prep the Chicken: Cut each chicken breast in half horizontally. This creates four thinner cutlets, which is key for quick and even cooking. If any parts are still a bit thick, gently pound them to an even thickness.
  3. Marinate the Chicken: In a medium bowl, whisk together 1 tablespoon of the olive oil, minced garlic, Italian seasoning, salt, and pepper. Add the chicken cutlets and toss them until they're fully coated. Cover the bowl and let it marinate in the fridge for at least 15 minutes—30 is even better if you have the time.
  4. Wilt the Spinach: While the chicken marinates, heat the remaining tablespoon of olive oil in a skillet over medium heat. Add the fresh spinach and cook, stirring occasionally, for just 2-3 minutes until it’s fully wilted. Transfer the spinach to a separate bowl and set it aside. Don't forget to drain any excess liquid!
  5. Mix the Creamy Filling: In another bowl, beat the softened cream cheese until it’s smooth. This is much easier when the cream cheese is at room temperature. Stir in the wilted spinach, half of the mozzarella (1/2 cup), and the Parmesan cheese, if you're using it.
  6. Optional Searing Step: For an extra layer of flavor, you can sear the marinated chicken in a hot skillet for 1-2 minutes on each side. This isn't required, but it gives the chicken a beautiful golden crust.
  7. Assemble the Casserole: Arrange the chicken cutlets in a single layer in your prepared baking dish. Spread the cream cheese and spinach mixture evenly over the top of the chicken. Sprinkle the remaining 1/2 cup of mozzarella cheese over everything. This will create that perfect Cheesy Chicken Casserole topping.
  8. Bake to Perfection: Place the dish in the preheated oven and bake for 20-30 minutes. The casserole is done when the chicken is cooked through (reaching an internal temperature of 165°F or 75°C) and the cheese on top is melted, bubbly, and lightly browned.
  9. Let It Rest: This is an important step! Let the casserole rest for about 5 minutes after taking it out of the oven. This allows the juices to redistribute and the sauce to set up a bit, making it easier to serve.

Notes

Pound chicken to an even thickness for tender, juicy results. It is critical to squeeze all excess moisture from the spinach to prevent a watery sauce. The casserole can be fully assembled a day in advance for meal prep; just add 10-15 minutes to the baking time. Boneless chicken thighs or shredded rotisserie chicken can be used as substitutes.
