This kitchen potato casserole recipe can easily be doubled to accommodate a crowd, a family gathering, or a potluck. Just use a larger casserole dish, and adjust the cooking time.  Another option is to make two separate casseroles. Once the potatoes are cooked, turn your oven to broil to darken the top a little. Looks even more mouth-watering and your cheesy potatoes for a crowd is bound to be a hit.
