Ingredients

Scale

Bread and Cheese

  • 6 slices of bread
  • 4 tablespoons butter, divided
  • 6 ounces cream cheese, softened
  • 12 slices Cheddar cheese

Soup Mixture

  • 1 (10.75 ounce) can tomato soup
  • 2 cups tomato juice
  • 2 large eggs
  • 1 teaspoon Italian seasoning
  • 1/2 teaspoon garlic powder
  • 1 large tomato, chopped

Topping

  • 1 cup shredded Italian blend cheese

Instructions

  1. Preheat and prepare baking dishes: Preheat your oven to 450°F (230°C) and grease a 9×13-inch baking dish to prevent sticking.
  2. Butter bread slices: Spread 2 tablespoons of the butter evenly on one side of each slice of bread. Place the buttered side down on a large baking sheet.
  3. Assemble sandwiches: Spread each bread slice on the unbuttered side with softened cream cheese. Add 2 slices of Cheddar cheese atop each slice, then cover with the remaining bread slices to form sandwiches.
  4. Butter sandwich tops and bake: Spread the remaining butter on top of each sandwich. Bake them at 450°F (230°C) for 12–14 minutes, flipping once halfway through until golden brown and the cheese is melted. Let cool for at least 15 minutes. Then reduce oven temperature to 350°F (175°C).
  5. Prepare tomato soup mixture: In a bowl, whisk together tomato soup, tomato juice, eggs, Italian seasoning, and garlic powder until combined. Stir in the chopped tomato to add freshness.
  6. Cut sandwiches into cubes: Cut the cooled grilled cheese sandwiches into 1-inch cubes for the casserole layering.
  7. Assemble casserole: Pour the tomato soup mixture into the greased baking dish. Evenly distribute the sandwich cubes over the top, pressing lightly so they submerge partially in the liquid.
  8. Add cheese topping and bake: Sprinkle the shredded Italian blend cheese over the casserole top. Bake at 350°F (175°C) for 25–30 minutes until the top is golden brown, bubbly, and heated throughout.

Notes

  • Allow grilling sandwiches to cool thoroughly before cutting to maintain shape in the casserole.
  • Use a sturdy bread that holds together well during baking, like white or sourdough.
  • Feel free to substitute tomato juice with fresh tomato puree for a fresher taste.
  • This dish can be prepared ahead; assemble fully and refrigerate, then bake before serving.
  • Serve with a fresh green salad for a complete meal.
