Preheat oven to 425°F. Grease a 9×13 inch baking dish.
Add half of potatoes evenly on the bottom of the dish. Season with salt and pepper. Spread 1 ½ cups Swiss cheese on top. Dot evenly with 2 tbsp butter. Repeat layers. Pour chicken broth over top.
Bake 45 minutes until potatoes are cooked and the cheese is golden brown. Serve hot.
