An amazing photographer from Montreal Quebec posted this recipe on her blog a few weeks ago. I have never had French Onion Soup so I decided to make it for my parents last weekend. I altered the recipe a bit after I translated it from French. It was the best soup I have ever had. Honestly, you have to make it. Thanks Catherine Giroux!
Here is the recipe I used:

French Onion Soup

SERVES 8 PEOPLE

1. Place 1 TB spoon of butter and a splash of Olive Oil in a large pot and cook 4 Large White Onions until they begin to brown (10-12 minutes)
2. Add 2-4 Cloves of chopped garlic, 2  TB of sugar, and a some Thyme. Continue to stir onions until brown
3. Sprinkle in about a TB of flour. Add 120 ML of White Wine and 2 Liters of Beef Stock. Bring to a boil.  REDUCE HEAT AND SIMMER GENTLY FOR 45 MINUTES
4. Reduce heat and simmer the soup for 45 minutes. Occasionally stirring. When soup is almost done toast Whole Grain English Muffins and then break into small pieces.
5. Fill soup bowls with a few pieces of the bread, add soup and  enjoy. Top with parmesan cheese if desired.
