Cut bread into 1-inch pieces. Place on baking sheet and put in oven at 225°F for 45 minutes-1 hour until dry, stirring occasionally. Or, let air dry for 1-2 days.
Preheat your oven to 350 F.
Melt butter over medium heat on stove. Once melted add the green parts of the scallions and cook for 2-3 minutes until softened.
Place bread cubes in a large mixing bowl and add in butter mixture, thyme, sage, rosemary, salt, and pepper. Mix until evenly coated.
Drizzle broth over the bread mixture and toss until well mixed.
Pour mixture into a greased 2.5 qt casserole dish and bake for 35-45 minutes, or until the stuffing is golden brown. If you are stuffing a turkey, leave out the broth, as the juices from the turkey will moisten it.
