*The Coq au Vin can be made in advance, covered and simmered over low heat on the stove or in a 280 degree F. oven until ready to serve. You will need to add more chicken broth or wine to keep the sauce from getting too thick. I also would recommend using chicken thighs to avoid dry chicken if you will be cooking this all day. **I like to mash my potatoes the super easy way by just letting my stand mixer do all the work. If you have never done this, just add the hot potatoes to your stand mixer and use the paddle attachment to mash the potatoes. It works so well!
