Made for My 3 Chefs - Very good soup and quite similar to my stove top recipe. I think the only thing I missed was that I caramelize my onions and it adds great colour and flavour. Thx Mrs. Sherm.

I really liked this soup from start to finish. I didn't have any dry onion soup mix, so I used Recipe #327297 instead. I reduced the butter to 1 tablespoon and 1 medium onion since I cut this in 1/2. I also had my own beef broth, so subbed the broth out for the bouillon too. Fast, and oh so tasty. I put this in my big coffee cup, sat and watched the day finish and enjoy this warm soup. Thank you Mrs. Sherm!
