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 dish: Preheat your oven to 450°F (230°C) and grease a 9×13-inch baking dish to prevent the casserole from sticking.
  2. Prepare the bread slices: Spread one side of each of the 6 bread slices with 2 tablespoons of butter total, then place the buttered sides down on an extra-large baking sheet.
  3. Assemble grilled cheese sandwiches: Evenly spread softened cream cheese on the top side of each bread slice. Then add 2 slices of Cheddar cheese per slice. Top each with remaining bread slices, forming sandwiches, and spread the tops with the remaining butter.
  4. Bake sandwiches: Bake the sandwiches for 12–14 minutes, flipping once halfway through, until golden brown and cheese inside has melted. Let them cool for at least 15 minutes to firm up.
  5. Reduce oven temperature: Lower the oven temperature to 350°F (175°C) in preparation for baking the casserole.
  6. Prepare tomato soup mixture: In a bowl, whisk together the canned tomato soup, tomato juice, eggs, Italian seasoning, and garlic powder. Stir in the chopped fresh tomato for added texture and flavor.
  7. Cut sandwiches into cubes: Once cooled, cut the grilled cheese sandwiches into 1-inch cubes to ensure even layering in the casserole.
  8. Assemble the casserole: Pour the tomato soup mixture into the greased baking dish. Spread the sandwich cubes evenly over the soup, pressing lightly to submerge them in the liquid.
  9. Add topping cheese: Sprinkle the shredded Italian blend cheese over the top of the layered casserole for a flavorful, melted topping.
  10. Bake the casserole: Bake for 25–30 minutes at 350°F (175°C) until the casserole is bubbling, golden brown, and thoroughly heated through.

Notes

  • Letting the grilled cheese sandwiches cool before cutting helps maintain their shape in the casserole.
  • Using Italian blend cheese on top adds a nice melty, savory crust. You can substitute with mozzarella or more Cheddar if preferred.
  • This dish can be made ahead of time: prepare the sandwiches and soup mixture, then assemble and refrigerate before baking.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven for best texture.
