What is Tomato Soup and Grilled Cheese Casserole?

Packed with familiar flavors, tomato soup and grilled cheese casserole is the perfect dish to whip up for a cozy night in. A layer of mini grilled cheese sandwiches tops a pan filled with a rich soup mixture made with tomatoes three ways (condensed soup, juice, and diced fresh) eggs and spices. A layer of shredded cheese finishes the casserole, which is baked in the oven to produce a golden crust and a soft interior akin to savory bread pudding. One bite will evoke memories of dunking a grilled cheese sandwich into a bowl of hot tomato soup.

How to Make Tomato Soup and Grilled Cheese Casserole

What You’ll Need

• Sourdough bread: Slices of sourdough bread, which have a sturdier texture than plain white bread and toast up beautifully, are a great pick for grilled cheese sandwiches, which are the foundation of the casserole. 
• Butter: Spreading softened butter on the slices of bread adds flavor and helps them brown in the oven.
• Cheeses: The sandwiches are stuffed with a decadent, melty combination of cream cheese and slices of Cheddar. The entire casserole also gets a generous sprinkling of shredded Italian blend or Cheddar cheese before it goes into the oven.
• Tomatoes: A trio of condensed tomato soup, tomato juice, and diced Roma tomatoes enrich the casserole with sweet, tangy, and fresh flavors.
• Eggs: A couple of beaten eggs thickens the soup mixture and binds everything together.
• Spices: Italian seasoning and garlic powder gives the casserole some mild garlicky and herbaceous flavors.

Making the Casserole

Bake assembled grilled cheese sandwiches, turning halfway through, until golden brown. Let them cool, then cut them into cubes. Mix the tomato soup, tomato juice, eggs, and spices together, then pour the mixture into a greased 9×13-inch baking dish. Add the sandwich cubes to the baking dish and sprinkle with Italian seasoning or cheese. Bake until the casserole is heated through.
