Chef’s Tips
- Caramelize onions slowly for the deepest flavor and sweetest finish.
- Mix different onion types for a balanced sweet-savory taste.
- Use Gruyere for classic melt and flavor, or swap with Swiss if preferred.
- If you don’t have broiler-safe bowls, melt the cheese on the bread separately and place it on top of the soup before serving.
