** If you want to use bread, you should cube it and leave it out overnight in a dish or dry in the oven at 270 F. on a sheet pan for about 5 minutes until hardened.
Preheat the oven to 350 F. Fry the onion, celery and garlic in butter for 5 minutes in a pan on the stove until softened. Remove. Place the dried bread cubes in a bowl, add salt and herbs, as well as fried vegetables.
Pour in the broth in small portions and gently stir the bread cubes so that they are evenly saturated with liquid. If you see that the bread is already quite wet, do not add the remaining broth.
Transfer to a baking dish and cover with foil or a lid. Bake at 350 degrees for half an hour. Then remove the foil and bake for another 10 minutes or until it is lightly browned on top. Serve immediately for best results.
