This is what is for dinner tonight! I am writing what I did & used. Smells fabulous!
2 medium yellow onions, sliced
1 stick butter (salted)
1 cup Red wine
3 cans Beef broth
dash worchestershire sauce
Melt Butter in a soup pot (I used my dutch oven, my stockpot would be too big). Cook onions in butter until they are translucent. Add the wine & simmer for 20 minutes. Add the beef broth & simmer.
I will be using wheat bread for the "Crouton" & a smoked cheddar for the cheese, because that is what I have, but it is best served with French bread for "crouton" & Swiss or provolone cheese.
Ladle soup into individual bowls add crouton & top with cheese. place under broiler until cheese is browned.
