Dutch Oven French Onion Soup

"I've also made this savory soup in a slow cooker for a fuss-free meal. It cooks on low for 3 to 4 hours." Denise Hruz, Germantown, WI

    This is a good "base" recipe- I made it with the following alterations:I substituted the water for additional beef broth. I also reduced the amount of sugar by about half, and used balsamic vinegar to balance the sweetness. I used about 1/3 cup of butter instead of 1/4 cup.I would use this as a launching pad to suit it to your tastes- other times I have added Worcestershire sauce or powdered onion soup mix.

    It was WAY too sweet, I agree about withholding the sugar. The onions were delcious, but the soup itself sucked. Sorry!

    This soup was sweet - maybe if you left out the sugar it would be okay but with it in, it was awful.
