Instructions
- Heat the olive oil in a large pot or a Dutch oven. Add the butter and let it melt.
- Add in the onion and give it a stir. Cook over medium heat for 1 hour to 1 hour and 30 minutes, stirring occasionally, until the onion is caramelized.
- Add in the flour and cook for 2 minutes. Pour in 1/2 cup beef stock and stir to deglaze the pot.
- Season with salt and add the rest of the beef stock. Turn the heat to medium high and bring the soup to a simmer. Cook for 35 to 45 minutes until it's reduced in half.
- Divide the soup between 4 oven-safe crocks, bowls or ramekins. Top with the baguette slices and shredded gruyere.
- Broil for 5 minutes or until the cheese is melted. Serve immediately.

Notes
- If not using ramekins: you can place a few slices of baguette on a baking sheet and top them with cheese. Broil (or bake) in the oven until the cheese is melted. Serve the soup in bowls and top with the toasted bread.
- You can use vegetable stock instead of beef stock for vegetarian French onion soup.
- Store the leftovers in an airtight container and refrigerate for up to 4 days. You can also freeze this soup for up to 3 months.
- Instead of gruyere, you can use Comte, Emmental or gouda.
