Preheat oven: Preheat your oven to 350°F (175°C).
Arrange ingredients in pan: Place the cubed chicken breasts, potatoes, and drained green beans in a single layer in a baking pan (a 9×13 inch pan or similar size works well).
Season with Italian dressing: Sprinkle the entire contents of the dry Italian dressing mix evenly over the chicken, potatoes, and green beans.
Drizzle with butter: Drizzle the melted butter evenly over the top of everything in the pan.
Cover and bake: Cover the baking pan tightly with aluminum foil.
Bake: Bake in the preheated oven for 1 hour and 10 minutes, or until the chicken is cooked through and the potatoes are tender.
Serve: Carefully remove the foil and serve the chicken, potatoes, and green beans hot.
Enjoy your simple and delicious one-pan chicken dinner!
