Preheat your oven to 375°F (190°C).
Heat olive oil in a skillet over medium heat.
Season chicken breasts with salt, pepper, garlic powder, and onion powder.
Sear the chicken in the skillet until golden brown on both sides (about 5 minutes each side).
In a separate bowl, mix cream cheese, sour cream, Parmesan, spinach, and artichokes.
Once chicken is browned, transfer it to a baking dish.
Spread the spinach-artichoke mixture evenly over the chicken.
Bake in the preheated oven for 20 minutes, or until chicken is cooked through.
Let the dish rest for 5 minutes before serving.
Garnish with additional Parmesan if desired.
