Cook the potatoes in a 350 F oven for one hour. Remove from the oven and scoop out the flesh into a medium-sized bowl. Do not turn off the oven.

Pour in the milk and add the sour cream and softened cream cheese, salt, pepper, garlic powder, and dried parsley. Mix everything well just until smooth.

Grease the bottom and sides of a baking dish. Spread the potato mixture evenly on the dish and bake for 35 minutes.

Take the casserole out of the oven and sprinkle the cheese evenly on top. Return to the oven and bake for 5 more minutes or until the cheese is completely melted.

Once the cheese has melted, top with the crumbled bacon and sliced green onions. Serve while hot.
