Instructions
  1. Preheat oven to 400°F (200°C).
  2. Caramelize onions in a pan over medium-low heat for 20-25 minutes, stirring occasionally, until they are dark golden brown.
  3. Add beef broth to the pan and bring to a boil, then reduce heat and let simmer for 10 minutes.
  4. Butter slices of bread and toast until golden brown.
  5. Assemble the soup by placing toasted bread slices in the bottom of a bowl, ladling the onion soup over the bread, and topping with grated cheese.
