Place the onions, olive oil and butter over medium-low heat in a dutch oven or large pot. Toss to coat them evenly, cover and cook 20 minutes until soft and transparent
Uncover, add salt and sugar and stir while cooking until browned and caramelized, about 25 minutes
Stir in the flour and cook 2-3 minutes until it forms a paste (add more butter if necessary)
Stir in 1 cup of beef stock and raise heat to medium, then add the remaining beef stock, wine, sage, and bay leaf
Bring to a boil, then reduce to a simmer for 30 minutes
Taste, adjust salt and pepper and hold on warm
Preheat oven to 325
Slice the bread into 1/2″ pieces, brush both sides with olive oil, place on a baking sheet and bake for 15 minutes on each side
Ladle the soup into the crocks, cover the surface with bread, completely cover with a thick coating of cheese and drizzle a little olive oil over each crock
Bake uncovered for 30 minutes at 325, remove and cool for a few minutes before serving
