There are two options for drying bread cubes for stuffing: 1. Air Drying: Arrange the bread cubes in a single layer on baking sheets or trays. Leave them uncovered at room temperature for about 1-2 days, depending on the humidity in your kitchen. Stir or toss them occasionally to ensure even drying. This method allows the bread to naturally lose moisture. 2. Oven Drying: Separate the bread cubes onto two baking sheets an an even layer. Bake at 350 degrees F for 15 minutes until dried out.
