In a large mixing bowl, combine your tomato soup with optional herbs and spices to elevate flavor. Stir until well blended.

Cube your choice of bread into bite-sized pieces. Melt butter in a skillet, then toss the bread cubes until coated and toast until golden brown.

Preheat your oven to 350°F (175°C). In a greased baking dish, pour in the prepared tomato soup mixture, spreading it evenly. Layer the toasted bread cubes over the soup.

Generously sprinkle a mix of your favorite cheeses over the top of the bread layer.

Place your casserole in the preheated oven and bake for 30-45 minutes, until the cheese is bubbly and golden brown.

Once baked, remove it from the oven and let it cool for about 5-10 minutes before serving.
