Chicken a la King is a easy comfort food, and a terrific way to use up roast chicken leftovers. It can be prepared in advance and frozen, then warmed up and served over rice or our favorite, puff pastry.
Tip: For crispy chicken skin, sprinkle salt over the chicken the day before you plan on cooking it. Leave the chicken uncovered on a plate in the fridge so the air and salt can draw out excess water.
