Preheat the oven to 350 degrees. While the oven is heating up, slice 1 loaf of bread into small pieces.
Cut the bread into about 1 inch pieces. Once the bread is all cut, spread it on a large baking sheet. Bake for 20 to 25 minutes so the bread can dry out.
Make sure to stir occasionally while the bread is cooking.
Melt ½ cup butter in a large pan. Once melted, add 1 diced onion and 4 diced celery stalks.
Allow the veggies to cook until they are tender. This usually takes about 10 to12 minutes.
Stir in 1 tablespoon minced garlic, ½ teaspoon dried thyme leaves, ½ teaspoon salt, ½ teaspoon black pepper, and ¼ cup chopped fresh parsley. Stir until well combined and heat for 2 to 3 minutes.
Put the dried bread pieces in a large mixing bowl and add the onion mixture. Stir together and gradually pour 2 cups chicken broth over the mixture.
It is best to gradually add the broth and stir as you go. The goal is to have the bread moist and not overly soggy so you may not need to use all of the broth.
You will need a 9X13 baking pan and make sure to spray with a non-stick cooking spray. Add the stuffing mixture and bake covered with foil for 30 minutes.
During the last 15 minutes, uncover the dish so the top can brown slightly.
