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
  • 1 can (28 oz) crushed tomatoes
  • 2 cups low-sodium vegetable or chicken broth
  • 1/2 cup heavy cream or sour cream
  • 1 teaspoon dried basil
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper
  • 6 cups cubed crusty bread (sourdough or Italian)
  • 1 1/2 cups shredded sharp cheddar cheese
  • 1 cup shredded mozzarella cheese
  • Butter (optional, for brushing top bread cubes)


Instructions

  1. Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish.
  2. 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.
  3. 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.
  4. In a large mixing bowl, combine cubed bread and cheeses. Pour tomato soup mixture over the top and gently stir to coat evenly.
  5. Transfer mixture to the casserole dish and press gently to flatten. Let sit for 5–10 minutes to soak.
  6. Optional: brush a few top cubes of bread with melted butter for extra crispness.
  7. Bake uncovered for 25–30 minutes or until bubbling and golden. Broil for 2–3 minutes for extra crisp top.
  8. Let rest 5–10 minutes before serving. Enjoy warm with a side salad or extra soup drizzle.

Notes

Let the bread dry out slightly before baking to prevent sogginess. Use a mix of cheddar and mozzarella for perfect flavor and melt. Add caramelized onions or swap in smoked gouda for fun variations.
