Preparing Chicken and Spinach Casserole with Cream Cheese

This layered approach ensures that every bite of the casserole is infused with flavor—from the juicy chicken to the cheesy, savory topping.

What You’ll Need

To recreate this comforting meal, gather the following ingredients:

  • 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
  • 2 cups fresh spinach
  • 8 ounces cream cheese (softened)
  • 1 cup shredded mozzarella cheese (divided)
  • 1/2 cup Parmesan cheese (optional for extra flavor)

You can also customize some ingredients; for instance, you may substitute the spinach with kale or use different types of cheese based on your taste preference.

Step-by-Step Instructions

Here’s a clear guide to making this casserole:

  1. Preheat your oven to 400°F (200°C) and lightly grease a 9×13-inch baking dish.
  2. Cut each chicken breast in half horizontally to make four thin cutlets. Pound the thicker parts with a meat mallet for even cooking.
  3. In a bowl, mix 1 tablespoon of olive oil, garlic, Italian seasoning, salt, and black pepper. Toss the chicken in this marinade, cover, and refrigerate for 15-30 minutes.
  4. Heat the remaining olive oil in a skillet over medium heat. Add the spinach and sauté for 2-3 minutes until wilted. Set aside.
  5. In another bowl, beat the softened cream cheese until smooth, then stir in the wilted spinach and 1/2 cup of mozzarella cheese (add Parmesan if using).
  6. (Optional) For extra flavor, sear the marinated chicken in the hot skillet for 1-2 minutes per side before baking.
  7. In the prepared baking dish, arrange the chicken, spread the cream cheese and spinach mixture on top, and sprinkle with the remaining mozzarella.
  8. 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. Allow the casserole to rest for 5 minutes before serving.
