Defrost hash browns completely and mix in 8x11 dish with cheese, soup, and sour cream.
Spread out evenly in pan.
Bake at 450 for 40-50 minutes (or until edges are browned). You can test the potatoes to see if they're done or if they need to cook a bit longer.
Once they are done, crush 2 cups (or handfuls) of Kettle Chips in a bag and spread them across your potato mixture and put back in the oven for 5 more minutes.
