Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish using olive oil or non-stick spray.
Season the chicken breasts with salt, pepper, and garlic powder on both sides.
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Sear the chicken breasts for 3-4 minutes on each side until lightly browned. They do not need to be fully cooked at this stage. Remove and set aside.
In a small bowl, combine the cream of chicken soup, sour cream, garlic powder, and 1/4 cup of water. Mix until smooth.
Place the seared chicken breasts in the prepared casserole dish in a single layer. Top each chicken breast with 2 slices of Swiss cheese, ensuring the cheese covers the chicken.
Pour the soup mixture evenly over the chicken and cheese, spreading it with a spatula to ensure full coverage.
In a medium bowl, mix the seasoned stuffing mix with the melted butter until the crumbs are lightly moistened.
Sprinkle the stuffing mixture evenly over the casserole to create a crunchy topping.
Bake the casserole in the preheated oven for 35-40 minutes, or until the chicken is fully cooked and the topping is golden brown. The internal temperature of the chicken should reach 165°F (74°C).
Remove the casserole from the oven and allow it to rest for 5 minutes before serving. Serve warm and enjoy!
