Preheat your oven to 375°F (190°C). Lightly grease a baking dish.

In a bowl, mix together the Caesar dressing, grated Parmesan cheese, black pepper, and garlic powder.

Place the chicken breasts in the prepared baking dish. Pour the Caesar mixture over the chicken, ensuring each breast is well coated.

Bake in the preheated oven for 30 minutes. After 30 minutes, sprinkle the shredded mozzarella cheese over the chicken.

Return to the oven and bake for an additional 10-15 minutes, or until the chicken is cooked through and the cheese is golden and bubbly.

Garnish with chopped fresh parsley before serving.
