Instructions

Caramelize the Onions
- In a large pot or Dutch oven, melt butter with olive oil over medium heat.
- Add sliced onions, salt, and sugar. Cook, stirring occasionally, for about 40-50 minutes until deep golden brown.
Make the Broth
- Add white wine to deglaze the pot, scraping up browned bits.
- Pour in beef broth, chicken broth (if using), Worcestershire sauce, thyme, bay leaf, and black pepper.
- Simmer for 20-30 minutes, then remove thyme and bay leaf.
Prepare the Bread & Cheese
- Preheat oven to 400°F (200°C).
- Place baguette slices on a baking sheet and toast for 5-7 minutes until golden.
Assemble & Serve
- Ladle soup into oven-safe bowls. Place toasted bread on top and sprinkle generously with Gruyère cheese.
- Broil on high for 2-3 minutes until cheese is bubbly and golden brown.
- Serve hot and enjoy!

Notes

For deeper flavor: Use homemade beef broth or let the soup simmer longer.
Cheese options: Gruyère is classic, but Swiss or mozzarella work too.
Make-ahead tip: Caramelized onions can be made a day in advance.
