Slice the bread so that each slice is at least 1-inch thick. If desired, remove crust. Cut each slice in half, then in 1-inch cubes. Set aside.
Coat the bottom of a baking sheet with olive oil. Arrange the bread in a single layer. Drizzle with olive oil. Generously season croutons with desired herbs and spices. Using your hands, gently toss croutons until seasoning is well-distributed. Return croutons to a single layer on the baking sheet.
Bake at 375 degrees until croutons are toasty, about 5-7 minutes. Turn; bake for another 5 minutes. Do not over cook. Remove from oven and cool.
