Notes

Be patient when caramelizing the onions; low and slow brings out the best flavor. Use a good quality beef broth for optimal taste; consider enhancing store-bought broth with soy sauce or miso. The bouquet garni is essential for added depth of flavor. Leftovers can be stored in the fridge for up to 3-4 days in an airtight container. Consider freezing without the bread and cheese for longer storage. Experiment with different onion types or cheese for variety!
