Preheat your oven to 350°F (175°C).
Season the chicken breasts with salt and pepper. Place them in a baking dish and bake until fully cooked, about 25-30 minutes.
Once done, let them cool a bit, then shred or chop into bite-sized pieces.
In a large bowl, combine the soft bread cubes with melted butter, diced onions, diced celery, dried sage, and dried thyme. Toss everything together until well mixed.
Add the shredded or chopped chicken to the bread mixture and mix well.
Gradually pour in the chicken broth, stirring continuously until the mixture is evenly moistened. Adjust the amount of broth as needed to achieve your desired consistency.
Transfer the mixture back into the baking dish and bake for an additional 25-30 minutes or until the top is golden brown and the dressing is cooked through.
Once baked, let it cool for a few minutes before serving. Enjoy your delicious homemade Chicken and Dressing!
