Ingredients

Scale

Sandwiches

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

Tomato 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 sticking and ensure easy cleanup.
  2. Butter the Bread: Spread 2 tablespoons of butter evenly on one side of each slice of bread. Place the buttered sides down on an extra-large baking sheet to prepare for assembling the sandwiches.
  3. Assemble the Sandwiches: On the non-buttered side of each bread slice, spread softened cream cheese evenly. Top with 2 slices of Cheddar cheese per slice, then cover each with a remaining slice of bread, forming a sandwich.
  4. Butter the Sandwich Tops: Spread the remaining butter on the top side of each sandwich to create a golden crust during baking.
  5. Bake the Sandwiches: Place the baking sheet with sandwiches in the oven and bake for 12–14 minutes, flipping them once halfway through, until the bread is golden brown and the cheese inside is melted. Set aside to cool for at least 15 minutes.
  6. Reduce Oven Temperature: Lower the oven setting to 350°F (175°C) to prepare for baking the casserole.
  7. Prepare Tomato Soup Mixture: In a mixing bowl, whisk together tomato soup, tomato juice, eggs, Italian seasoning, and garlic powder until smooth. Fold in the chopped tomato for added freshness and texture.
  8. Cube the Sandwiches: Cut the cooled grilled cheese sandwiches into 1-inch cubes, ensuring they are bite-sized for the casserole.
  9. Assemble the Casserole: Pour the soup mixture into the greased baking dish. Evenly distribute the sandwich cubes over the top, pressing gently to submerge them slightly into the liquid.
  10. Add Cheese Topping: Sprinkle the shredded Italian blend cheese evenly over the casserole to add a flavorful cheesy crust.
  11. Bake the Casserole: Place the dish in the oven and bake for 25–30 minutes, or until the casserole is golden brown, bubbly, and thoroughly heated through.

Notes

  • For best results, allow the sandwiches to cool completely before cubing to prevent them from falling apart in the casserole.
  • You may substitute the Italian seasoning with an equal amount of dried oregano or basil if preferred.
  • Feel free to use different types of cheese blends for a unique flavor profile.
  • This casserole can be prepared a day ahead; cover and refrigerate before baking.
  • Reheat leftovers in the oven at 350°F until warmed through, keeping the cheese topping crisp.
