How to Make Grilled Cheese Tomato Soup Step-by-Step

Step 1: Butter both sides of each bread slice. Toast the buttered slices lightly in a skillet until golden brown. Layer the toasted bread slices in a casserole dish, adding a generous layer of shredded sharp cheddar cheese between each slice to build the classic grilled cheese texture.
Step 2: In a medium bowl, whisk together canned or homemade tomato soup with milk or cream, and dried herbs like basil and oregano. This mixture will soak into the bread, adding richness and depth.
Step 3: Pour the tomato soup mixture evenly over the layered bread and cheese in the casserole dish. Press lightly so the bread absorbs the mixture but does not become soggy. Sprinkle grated Parmesan cheese evenly on top to form a golden crust.
Step 4: Preheat oven to 375°F (190°C). Bake the casserole for 25-30 minutes until the top is bubbly and golden brown. Let it rest for 5-10 minutes before serving to allow it to set and enhance flavors.
