what you need...
8-10 pcs medium onions (sliced into thin rings)
2 tsp Cooking oil
1/4 cup butter
2 pcs bay leaves
3-4 cups beef broth
Toasted bread (optional)
cheddar cheese (grated, optional)
what to do...
1. In a sauce pan, saute onions and butter in oil over a medium flame. Cook until onion turns dark brown and caramelizes.
2. Add bay leaves and beef broth.
3. Cook for about 10-15 minutes.
4. Serve hot. Best served with toasted bread, topped with cheese.
Make sure to cook onions until they are really dark brown before adding the liquid. This process of caramelization brings out the natural sweetness of the onion and gives the soup its intense flavor.
