Preheat your oven to 375°F (190°C).
Heat olive oil in a skillet over medium heat.
Season chicken breasts with salt, pepper, and garlic powder.
Sear the chicken in the skillet for about 5 minutes on each side until golden.
In a bowl, mix cream cheese, sour cream, Parmesan, spinach, and artichokes.
Place seared chicken in a baking dish.
Spread the spinach-artichoke mixture over each chicken breast.
Bake in the oven for 20 minutes or until the chicken is cooked through.
Remove from the oven and let it rest for a few minutes.
Garnish with fresh parsley before serving.
