Description
A nostalgic blend of creamy tomato soup and golden, cheesy bread, this casserole is comfort food reimagined in one warm, baked dish.
Ingredients
- 1 tablespoon olive oil
- 1 small yellow onion, diced
- 3 garlic cloves, minced
- 2 tablespoons tomato paste

- Butter (optional, for brushing top bread cubes)
Instructions
- Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish.
- In a large skillet, heat olive oil over medium heat. Sauté onion until soft, about 5 minutes. Add garlic and tomato paste, and cook for 1 minute.
- Add crushed tomatoes, broth, cream, basil, salt, and pepper. Stir and simmer for 10 minutes. Blend with immersion blender for a smooth texture if desired.

Notes

How to Make Tomato Soup & Grilled Cheese Casserole
The Key Ingredients That Bring It All Together
To make a truly satisfying Tomato Soup & Grilled Cheese Casserole, start with high quality, simple ingredients. The casserole works best with crusty sourdough or Italian bread, cubed for texture and structure. For the cheese, sharp cheddar brings bold flavor, while mozzarella adds that melty, stretchy goodness. You’ll want to avoid pre shredded blends, they just don’t melt the same.
The tomato soup base is what sets this dish apart. Instead of just opening a can, we blend rich tomato paste with garlic, onion, broth, and a hint of cream for smoothness. The result? A homemade soup that’s cozy but layered with flavor.
Once you’ve prepped your bread and cheese, pour the tomato mixture over everything in a casserole dish. Let it soak just long enough to soften the bread, but not turn it mushy. Bake until golden and bubbling, and enjoy that irresistible toasted cheese crust on top.
This method blends all the elements of a grilled cheese sandwich with homemade soup, creating something more cohesive and indulgent than either alone. If you’re into variations, swap the cheddar for smoked gouda or try sour cream instead of cream in the base.

Tools You’ll Need (And Probably Already Have)
This recipe doesn’t demand special equipment. A sharp bread knife, mixing bowls, a sauté pan, and a sturdy baking dish are all you need. A blender or immersion blender helps with the tomato base, but even that’s optional if you prefer a chunkier texture.
Much like our Honey Buffalo Chicken and Mac and Cheese, this casserole is all about flavor with minimal fuss. It’s the kind of dish you can pull together midweek without a trip to the specialty store, and still impress every single time.

How Tomato Soup & Grilled Cheese Casserole Works
The Science of Comfort in One Pan
The genius of Tomato Soup & Grilled Cheese Casserole is how it blends two comfort staples into a single, balanced bite. The creamy tomato base softens the bread just enough to absorb flavor, while the cheese binds everything with richness. When baked, the top crisps up, creating a contrast in textures that makes every forkful satisfying.
Tomato brings natural acidity and umami, balancing the richness of the cheese. Bread acts like a sponge, soaking up that seasoned base without falling apart, especially if you use denser loaves like sourdough or artisan white. And because the casserole is layered and baked, you get uniform flavor in every scoop, no soggy bottoms or dry edges.
Cheese melts differently depending on type. Sharp cheddar melts into a bold base, while mozzarella adds a mild, gooey pull. Combining both gives you the best of both worlds.
Like our Tomato Soup Guide, this recipe highlights how layering flavors and textures can elevate even the simplest ingredients.
Tips for Success Every Time
To make the best Tomato Soup & Grilled Cheese Casserole, cube the bread and let it sit out to dry slightly before assembling, this helps it hold up better in the bake. Don’t skip sautéing your aromatics (onion, garlic), they deepen the flavor of the tomato base.
Always preheat your oven and check the center of the casserole to make sure it’s fully heated through. For golden perfection, broil the top for the last 2–3 minutes. Want extra crisp? Butter a few top bread cubes before baking.
Much like our Chicken Broccoli Cheese Soup, this dish rewards patience. Letting it rest for 5–10 minutes after baking helps it set and makes serving easier.
With the right technique and simple tweaks, you can serve this classic in a way that tastes like childhood, only better.
