Main Ingredients

  • 8–10 slices Thick slices of sturdy white or sourdough bread Choose bread with a firm crumb and a sturdy crust.
  • 1 cup Butter Enough to butter both sides of the bread slices.
  • 3–4 cups Sharp cheddar cheese, shredded Grate from a block for better melt and flavor.
  • 3 cups Canned or homemade tomato soup Canned keeps this recipe fast, while homemade deepens flavor.
  • 1 cup Milk or cream Use cream for richness or milk for a lighter finish.
  • 1–2 teaspoons Dried herbs (basil and oregano) Adds warmth to the soup mixture.
  • 1/2 cup Grated Parmesan cheese Sprinkled on top for a golden crust.

Instructions
 

Preparation

  • Butter both sides of each bread slice.
  • Lightly toast the buttered slices in a skillet over medium heat until golden brown and slightly crisp.

Layering

  • Layer the toasted bread slices in a casserole dish, overlapping slightly and adding a layer of shredded cheddar cheese between each slice.

Tomato Soup Mixture

  • In a bowl, whisk together the tomato soup, milk/cream, and dried herbs.
  • Season lightly with salt and pepper.

Combining and Topping

  • Pour the tomato soup mixture over the bread and cheese layers.
  • Press lightly so the bread absorbs the mixture.
  • Sprinkle grated Parmesan cheese on top.

Baking

  • Preheat oven to 375°F (190°C) and bake the casserole for 25–30 minutes until bubbly and golden brown.
  • Let it rest for 5–10 minutes before serving.

Notes

Serve with a side salad or pickles to cut through the richness. Leftovers can be stored in airtight containers for up to 3-4 days, and can be reheated easily.
