2. Melt butter in a heavy pot over medium heat.
3. Add in sliced onions, sugar, thyme, bay leaf and salt; cook stirring occasionally until onions are a deep golden brown (this should take about 25 minutes (you may need to do the onions in two batches to caramalize properly).
4. Add in flour and cook stirring for 1 minute.

6. Sir in broth, water and black pepper; simmer uncovered for about 30-35 minutes.
7. While the soup is simmering set the oven rack to middle position at set to 350 degrees.

12. Place the slices of Gruyere cheese over the top allowing the ends to hang over the rims of the crocks, then sprinkle with grated parmesan cheese.
