Step‑by‑Step Instructions for Tomato Soup and Grilled Cheese Casserole
Step 1: Prepare Ingredients
Begin by cubing your favorite bread, such as sourdough or brioche, and place it in a large mixing bowl. Melt several tablespoons of butter and pour it over the bread cubes, gently tossing to ensure each piece is well-coated. You’re looking for that glistening buttery finish, which helps achieve a crunchy texture during baking. Set the bowl aside as you move on to the next step.
Step 2: Combine Soup Base
In a separate bowl, combine the tomato soup with any optional flavor enhancements, such as fresh herbs, chili flakes, or Worcestershire sauce. Stir well until all ingredients are thoroughly mixed. The vibrant color of the soup should be rich and inviting, indicating a flavorful base for your Tomato Soup and Grilled Cheese Casserole. Ensure you’ve got a good blend, as it will coat your bread beautifully.
Step 3: Layer the Casserole
Preheat your oven to 350°F (175°C). In a greased baking dish, layer half of the buttered bread cubes evenly on the bottom. Pour half of the soup mixture over this bread layer, making certain to cover it completely. Next, add the remaining bread cubes on top, creating a solid foundation for the casserole. This layering ensures every bite will be a delightful mix of the creamy soup and crunchy bread.
Step 4: Add Cheese
Generously sprinkle your chosen cheese blend—like Cheddar, mozzarella, or Italian mix—over the top layer of bread. Ensure even coverage for a perfectly melty, golden topping. The cheese will bubble and form a delightful crust as it bakes, becoming that irresistible layer we all love on a classic grilled cheese.
Step 5: Bake
Place the assembled casserole in your preheated oven and bake for 30 to 45 minutes. Keep an eye on it—when the cheese is bubbling and turning a lovely golden brown, you’ll know it’s nearly ready. This baking time allows the flavors to meld together beautifully, creating a warm and inviting dish that’s perfect for any family gathering.
Step 6: Cool and Serve
Once baked to perfection, remove the casserole from the oven and let it cool for about 10 minutes. This resting time enhances the flavors and allows the casserole to set, making it easier to portion out. The appealing aroma of your Tomato Soup and Grilled Cheese Casserole will fill the kitchen, inviting everyone to gather around the table.

Make Ahead Options
These Tomato Soup and Grilled Cheese Casserole options are perfect for busy weeknights when you want to save time without sacrificing flavor! You can prep the casserole up to 24 hours in advance by assembling it fully, then cover it tightly with plastic wrap or foil and refrigerate. To maintain the quality, ensure the bread is well-coated in butter to prevent sogginess. When you’re ready to bake, simply remove it from the fridge and increase the baking time by about 10-15 minutes. For an even quicker option, you can also prepare the bread cubes and soup mixture separately, storing them in the fridge for up to 3 days. Just layer and bake when you’re ready to enjoy this comforting dish!
