French Onion Soup with Beef Broth
Recipe courtesy of Harvard University Dining Services
Cook Time 1.5 hrs.
Serves 100
Ingredients:
- 1 cup olive oil
- 4 ounces butter
- 25 pounds white onions, thinly sliced
- 1 cup dry sherry or cognac
- 5 gallons beef stock
- 4 ounces fresh thyme, chopped
- 8 ounces chives, chopped
- 1 ounce black pepper
Preparation:
- In a soup pot over medium heat, add butter and oil. When butter is melted, add onions. Cook, stirring occasionally so onions do not burn.
- As soon as onions start to brown, approximately 15 minutes, reduce heat to medium-low and stir more often, until onions are a rich brown color, about 45 minutes.
- Add sherry or cognac and beef stock. Bring to a boil and reduce heat to simmer. Simmer 20 minutes.
- Add thyme, chives, and pepper. Serve.
