Creamy Buffalo Chicken Casserole

0 Preheat the oven to 350℉.
1 Peel and cut the potatoes into 1" cubes and place them in a large pot on the stove. Cover the potatoes with water and add 2 teaspoons of salt (optional). Bring to a boil and boil for 15 minutes until the potatoes are fork tender. Drain and then mash potatoes with a potato masher. Add the butter, sour cream, and crumbled bacon. Stir to combine, then set aside.

3 To a casserole dish, layer the loaded mashed potatoes, then the buffalo-ranch chicken mixture, and top with shredded cheese. 
4 Cover the dish with foil and bake for 30 minutes. Uncover and broil for 3 minutes to brown cheese. 
5 Garnish with green onions, serve, and enjoy!
