Set your slow cooker on high, then add onions,
garlic, brown sugar, butter, salt and balsamic
and mix until combined. Cover and let cook for
60 minutes, stirring occasionally, until onions
are a bit caramel and brown on the edges. Add
in flour, then stir thoroughly and let sit for
5 minutes. Add in beer, beef stock, thyme, and
pepper, then turn heat down to low, cover and
cook for 6-8 hours.

Before serving, cut French bread or baguette
into slices. Fill soup bowls to the top, then
cover with slice of bread and a slice of
cheese. Set under the broiler for 2-3 minutes,
or until cheese is bubbly and golden brown. Be
careful when serving as bowls will be hot!
