Creamy chicken and veggies nestled in a fluffy cloud of mashed potatoes, topped with melted cheese, true comfort food at it's finest! A simple and easy recipe, this casserole can be assembled in advance and popped into the oven an hour before serving. Serve with warm buttered biscuits. Enjoy! Tip: The hot mashed potatoes are especially tasty prepared with chicken broth in place of water, and cream cheese in place of the usual milk & butter. I sometimes skip the cream of chicken soup--equally delicious! Can be made using leftover rotisserie chicken.
