Level of Difficulty:
Time Needed:
15 min.
1 stick butter
1 can beef bouillon
1 tsp. Worcestershire sauce
Grated Parmesan cheese
1 1/2 cup onion rings
1 can water
Seasoned Croutons
Grated Swiss Cheese
(I don't think they make canned beef bouillon anymore. My mom said the can was in the soup section and typically the size of a condensed soup can. If Wiki Answers gives me an idea I'm thinking that the can of water was for the can of beef bouillon to dilute it to that of beef stock. So I'm thinking to sub. 2 cans of beef stock for the 1 can of beef bouillon and omit the water or if you have the bouillon cubes just use one and follow your directions for that).
