How to Make Grilled Cheese and Tomato Soup Casserole

Step 1: Prepare the Bread and Cheese

Start by buttering one side of each slice of bread generously. Layer sharp cheddar or your choice of cheese between two slices, ensuring the buttered sides face out. Cut each sandwich into halves or quarters for easy layering.

Step 2: Mix the Tomato Soup Base

In a bowl, combine your tomato soup with milk or cream and season with salt, pepper, and any optional herbs. Stir well to create a smooth, creamy illusion that will soak into the bread while baking.

Step 3: Assemble the Casserole

Layer the bottom of a greased casserole dish with sandwich pieces, then pour half of the soup mixture over them. Repeat the layers, making sure the sandwiches are well-coated but not swimming.

Step 4: Bake Until Golden

Bake the casserole in a preheated oven at 350°F (175°C) for about 30-35 minutes or until the top is bubbly and golden brown with a crispy texture.

Step 5: Let It Rest and Serve

Allow the casserole to rest for 5-10 minutes before serving to let it set slightly, ensuring each slice holds together beautifully.

Pro Tips for Making Grilled Cheese and Tomato Soup Casserole

• Use Thick Bread: Thick slices help maintain structure and prevent sogginess during baking.
• Butter Generously: Don’t skimp on butter for that perfect grilled texture on each sandwich piece.
• Choose Good Cheese: Sharp cheddar melts well and provides robust flavor but feel free to blend cheeses for complexity.
• Drain Overly Thick Soup: If your tomato soup is too thick, thin it slightly with broth or milk to avoid dryness.
• Rest Before Serving: Letting the casserole sit after baking improves slicing and flavor melding.

How to Serve Grilled Cheese and Tomato Soup Casserole

Garnishes

A sprinkle of freshly chopped basil, a drizzle of balsamic glaze, or a little shredded Parmesan on top can elevate the casserole’s flavor and presentation.

Make Ahead and Storage

Storing Leftovers

Place any leftover casserole in an airtight container and refrigerate for up to 3 days. It reheats well and retains much of its original flavor and texture.

Freezing

This casserole freezes beautifully. Wrap tightly in plastic wrap and foil, then freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

Reheat leftovers in a preheated oven at 350°F (175°C) for about 15-20 minutes or until warmed through to maintain crispness, avoiding soggy texture from microwaves.

FAQs

Can I use different types of bread for this casserole?

Absolutely! While thick white or sourdough bread works best for structure and texture, multigrain or even rye bread can offer interesting flavors and are great substitutes.

Is homemade tomato soup better than canned for this recipe?

Both work well, but homemade soup allows you to control seasoning and sweetness, creating a fresher taste. High-quality canned soup is an excellent shortcut without compromising much on flavor.

Can I make this casserole vegan?

Yes! Use plant-based cheese and butter alternatives, along with a vegan-friendly tomato soup, to keep it delicious and animal-free.

How do I avoid the casserole becoming soggy?

Choosing thick, sturdy bread and thoroughly buttering slices ensure they crisp nicely. Baking at the right temperature and letting the casserole rest before serving also helps prevent sogginess.

Can I add protein to this dish?

Adding cooked bacon, ham, or even shredded chicken between layers can boost the protein content and add savory depth to your casserole.
