Preheat oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
If chicken breasts are thick, slice horizontally or pound to 1-inch thickness. Pat dry and season with salt and pepper.
(Optional) Heat olive oil in a skillet over medium-high heat. Sear chicken 2–3 minutes per side until lightly golden. Transfer to baking dish.
In a mixing bowl, combine sour cream, mayonnaise, garlic powder, onion powder, smoked paprika, salt, black pepper, and Parmesan cheese. Mix until creamy.
Spread mixture evenly over chicken breasts. If desired, sprinkle mozzarella or cheddar cheese on top.
Bake uncovered for 35–40 minutes, until internal temperature reaches 165°F (74°C).
For a golden top, broil for 2–3 minutes at the end, watching closely.
Let rest for 5 minutes. Garnish with parsley, chives, or red pepper flakes before serving.
