Preheat the Oven: Preheat your oven to 375°F (190°C). Lightly grease a baking dish with non-stick cooking spray.

Prepare the Chicken: Season the chicken breasts with salt, black pepper, and paprika on both sides. Place the chicken in the prepared baking dish.

Make the Garlic Parmesan Mixture: In a small bowl, mix together the mayonnaise, grated Parmesan cheese, garlic powder, and Italian seasoning until well combined.

Spread the Sauce : Evenly spread the garlic Parmesan mixture over the tops of the chicken breasts, coating each one generously.

Add the Toppings: Sprinkle the shredded mozzarella cheese over the chicken, followed by the optional breadcrumbs if you prefer a crispy topping.

Bake the Chicken: Bake in the preheated oven for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (74°C) and the topping is golden and bubbly.

Serve: Remove the chicken from the oven and let it rest for 5 minutes before serving. Pair it with your favorite side dishes like roasted vegetables, mashed potatoes, or a fresh salad.
