Ingredients
Method
- Slice and prepare the onions by peeling and cutting them into thin half-moons.
- Melt butter and olive oil in a pot, add onions, cover for 10 minutes, then caramelize for 45-60 minutes.
- Deglaze the pot with sherry or wine, scraping up caramelized bits.
- Add beef stock, thyme, and bay leaf; simmer uncovered for 30 minutes.
- Toast baguette slices in the oven at 400°F until crisp.
- Ladle soup into bowls, top with toasted bread and cheese, then broil until cheese is bubbly.
Notes
Use a heavy pot for even cooking. Grate your own cheese for best melting. Store leftovers without bread and cheese.
