Preheat the oven to 350 degrees F. Spritz a 9x13 baking dish with nonstick spray. Place the bread in a large mixing bowl.
Heat the butter in a large skillet or Dutch oven over medium heat. Once melted, stir in the onion, celery and garlic with the kosher salt and pepper. Cook until the onions and celery soften, about 8 to 10 minutes.
Stir in the sage, thyme, and bouillon. Cook for another minute. Stir in 1 1/2 cups of water.
Pour the vegetable mixture over the bread crumbs and toss well to coat.
In the same skillet, off of the heat, whisk together the remaining 1 ½ cups water, fresh parsley, and 2 eggs. Pour this mixture into the bread cubes and stir and fold the bread cubes until thoroughly combined.
Bake the stuffing for 40-45 minutes, until the internal temperature registers 160 degrees F. If the stuffing is getting too browned, you can tent it with foil.
Let cool for at least 5 minutes. Sprinkle with minced parsley. Cut the casserole into 8 portions and serve.
