In a large mixing bowl, combine stale bread with egg, water, celery, onion, mushrooms, apples, and seasonings. Combine well.
Press into a 9-inch square baking dish (about 2-3 quart). Once you have all your stuffing in the dish, press it in firmly.
Cover stuffing with foil. Bake for 60 minutes in a 350 degree F oven. You can make this a day ahead of time too! ENJOY.
Notes
For the bread, white or wheat is fine. I like to take my bread and let it sit open on the counter overnight, making it a little stale. Too fresh of bread will get soft and soggy.
This recipe for classic stuffing will easily double. I would use a lasagna pan or 13×9 for a doubled batch of the dressing.
You can make this stuffing 24 hours ahead of time to keep things simple on the big day. I suggest you take it out of the refrigerator at least an hour or two before putting into the oven. If it’s still cold, add extra time to adjust for the chill.
