Ingredients You’ll Need

Before we dive into the process, let’s gather the essentials:

Ingredients of Grilled Cheese Tomato Soup Casserole
  • Sliced bread (sourdough or white bread works best)
  • Butter for spreading
  • Shredded cheese (cheddar and mozzarella blend recommended)
  • Tomato soup (canned or homemade)
  • Heavy cream for creaminess
  • Fresh basil for garnish

This short ingredient list ensures that the dish remains accessible and budget-friendly.

How to Make the Perfect Casserole

This recipe comes together in three simple steps: prepping the grilled cheese layer, making the tomato soup base, and assembling the casserole.

Step 1: Prepare the Grilled Cheese

Apply a thin, even layer of butter to one side of each bread slice. Heat a skillet over medium heat and cook until golden brown on both sides, layering shredded cheese in between. Let them cool slightly, then cut into squares.

Tip: Using day-old bread helps prevent sogginess in the casserole.


Step 2: Create the Tomato Soup Base

Combine tomato soup, heavy cream, and seasonings like garlic powder, black pepper, and a pinch of sugar in a saucepan. Heat until warm but not boiling. This step enhances the soup’s flavor, giving it a creamy and robust profile.

Tip: Add fresh basil or a dash of red pepper flakes for extra flavor.

Step 3: Assemble the Casserole

Layer the grilled cheese squares in a greased baking dish. Pour the tomato soup mixture evenly over the top, ensuring it seeps into every crevice. Add a generous layer of shredded cheese on top to cover everything.

Tip: For an extra crunch, add breadcrumbs or crumbled crackers on top before baking.

Bake to Perfection Preheat your oven to 375°F (190°C). BBake the casserole for 25 to 30 minutes, or until the cheese is bubbly and golden brown, creating a deliciously melted top layer. Allow it to rest for a few minutes to cool slightly before serving.

Tip: Serve with a simple side salad for a complete meal.
