• ½ teaspoon black pepper

• 2 cups fresh spinach
• 8 ounces cream cheese, softened

Tools & Equipment Needed

Having the right tools makes cooking this casserole seamless:

• 9×13-inch baking dish
• Medium mixing bowl
• Skillet or sauté pan
• Whisk or fork for mixing
• Cutting board and sharp knife
• Meat mallet or rolling pin (for pounding chicken)

Optional: Instant-read thermometer to ensure perfectly cooked chicken.

Step-by-Step Instructions

Here’s how to bring this creamy, cheesy casserole to life—step by step.

1. Prep the Oven and Baking Dish

Preheat your oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish to prevent sticking.

2. Prepare the Chicken

Cut each chicken breast in half horizontally to create four thin cutlets. Pound the thicker ends to ensure even thickness, which helps the chicken cook uniformly.

3. Marinate the Chicken

In a small bowl, whisk together 1 tablespoon olive oil, minced garlic, Italian seasoning, salt, and black pepper. Toss the chicken in this marinade, cover, and refrigerate for 15–30 minutes. This step infuses the chicken with flavor and makes it tender.

4. Sauté the Spinach

In a skillet, heat the remaining 1 tablespoon olive oil over medium heat. Add the spinach and cook for 2–3 minutes, just until wilted. Set aside to cool slightly.

5. Prepare the Creamy Filling

Beat the softened cream cheese in a bowl until smooth. Stir in the sautéed spinach, ½ cup mozzarella, and Parmesan cheese if using. This will form a rich, velvety filling for the casserole.

6. Optional Chicken Sear

For added flavor, you can sear the marinated chicken in a hot skillet for 1–2 minutes per side before baking. This step is optional but adds a golden crust and extra depth of flavor.

7. Assemble the Casserole

Arrange the chicken in the prepared baking dish. Spread the cream cheese and spinach mixture evenly over the chicken. Top with the remaining ½ cup mozzarella cheese.

8. Bake to Perfection

Bake in the preheated oven 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. Rest and Serve

Allow the casserole to rest for 5 minutes before serving. This helps the filling set slightly, making it easier to slice and serve.
