To prepare a waldorf chicken boats recipe, you will first need to prepare the ingredients for the recipe. Wash the chicken breasts and pat them dry with paper towels. Cut the wings in half lengthwise and scoop out the insides. Place the wing halves in the bottom of an 8 x 8-inch baking dish. Fill each half with chicken. Cover the dish with plastic wrap and refrigerate for at least 1 hour. Preheat the oven to 375?F (190?C) and bake for 20 to 25 minutes or until chicken is no longer pink. Remove from oven and let stand for 5 minutes before serving.
