Ingredients

Scale

For the Grilled Cheese Sandwiches

  • 6 slices bread (sourdough or white)
  • 4 tbsp butter
  • 6 oz cream cheese (optional)
  • 12 slices sharp cheddar cheese

For the Tomato Soup Mixture

  • 1 can (10.75 oz) condensed tomato soup
  • ½ cup tomato juice
  • 2 large eggs
  • ½ tsp garlic powder
  • 1 tsp Italian seasoning
  • ½ cup diced tomatoes (optional)

Topping

  • 1 cup shredded Italian blend cheese


Instructions

  1. Preheat Oven: Preheat your oven to 450°F (230°C) to prepare for baking the grilled cheese sandwiches.
  2. Prepare Sandwiches: Butter each slice of bread generously. Assemble grilled cheese sandwiches by layering cheddar cheese slices and optional cream cheese between the bread slices.
  3. Bake Sandwiches: Place the sandwiches on a baking sheet and bake for 12–14 minutes, flipping once halfway through to ensure even browning. Remove from oven and let cool slightly before cutting into 1-inch cubes.
  4. Reduce Oven Temperature: Lower the oven temperature to 350°F (175°C) to prepare for baking the casserole.
  5. Mix Soup Base: In a large bowl, whisk together the condensed tomato soup, tomato juice, eggs, garlic powder, Italian seasoning, and optional diced tomatoes until smooth and well combined.
  6. Assemble Casserole: Grease a 9×13-inch baking dish lightly. Pour the tomato soup mixture evenly into the dish.
  7. Add Sandwich Cubes: Layer the cubed grilled cheese sandwiches over the tomato soup mixture, pressing them gently to submerge slightly in the liquid.
  8. Add Cheese Topping and Bake: Sprinkle the shredded Italian blend cheese evenly over the casserole. Bake in the 350°F oven for 25–30 minutes or until the topping is bubbly and golden brown.

Notes

  • Use sourdough bread for a tangier flavor and better texture.
  • Adding cream cheese inside the sandwiches enhances creaminess but can be omitted for a lighter version.
  • Be sure to flip sandwiches during the initial bake to get an even golden crisp.
  • Press the sandwich cubes gently into the soup mixture so they absorb flavor without becoming too soggy.
  • If you prefer a spicier kick, add a pinch of cayenne pepper to the soup mixture.
  • Serve warm and enjoy with a fresh green salad for a balanced meal.
