Preheat your oven to 400°F (200°C) and grease a large baking dish with cooking spray or a little olive oil.
In a large bowl, combine the chicken pieces, salt, black pepper, garlic powder, and paprika. Toss until the chicken is evenly coated with the seasonings.
In a large skillet, melt the butter over medium heat. Add the minced garlic and sauté for about 1 minute, until fragrant.
Add the seasoned chicken to the skillet and cook for 5-7 minutes, stirring occasionally, until the chicken is browned and cooked through.
Transfer the cooked chicken to the prepared baking dish. Sprinkle the mozzarella and Parmesan cheese evenly over the top.
Bake in the preheated oven for 10-15 minutes, or until the cheese is melted and bubbly.
Remove from the oven and let it cool for a few minutes. Garnish with fresh parsley if desired before serving.
