We really like using homemade or bakery sourdough bread when making homemade stuffing. Sourdough is a hearty, chewy bread with a flavor that goes so well with stuffing. But you can really use any bread. Try to avoid soft, fluffy bread because it can turn to mush pretty quickly. However, if that is what you have we recommend drying the cubes out overnight or toasting in an oven until dry and toasty before using in your stuffing. Often your local grocery store or bakery will sell bags of stuffing cubes around the holidays that you can also use in this recipe. If using dried bread cubes, you might need to chicken broth to ensure that your stuffing isn't too dry.
