🛒 Ingredients

For the Casserole:

  • 8 slices of white or sourdough bread
  • 4 tablespoons butter, softened
  • 2 cups shredded cheddar cheese (or a mix of cheddar and mozzarella)
  • 1 can (10.5 oz) condensed tomato soup
  • ¾ cup milk or cream
  • 1 teaspoon garlic powder
  • ½ teaspoon onion powder
  • Salt & pepper to taste
  • ½ teaspoon dried basil or Italian seasoning

Optional Topping:

  • Extra shredded cheese or a sprinkle of breadcrumbs for crunch

👩‍🍳 Instructions

  1. Preheat oven to 375°F (190°C). Lightly grease an 8×8-inch baking dish.
  2. Butter the bread: Spread butter on one side of each bread slice, then cut each slice into quarters.
  3. Layer the casserole: Arrange half of the buttered bread (butter side down) in the baking dish. Sprinkle with half of the shredded cheese.
  4. Mix the soup layer: In a bowl, whisk together tomato soup, milk, garlic powder, onion powder, salt, pepper, and basil. Pour half of this mixture over the bread and cheese.
  5. Repeat layers: Add remaining bread and cheese, then pour the rest of the soup mixture evenly on top.
  6. Top it off: Sprinkle with extra cheese (and breadcrumbs if using).
  7. Bake for 25–30 minutes, until hot and bubbly with a golden top.
  8. Cool slightly before serving — it’s best enjoyed warm and gooey!
