Instructions

In a large pot over medium-low heat, heat olive oil and melt butter. Add the onions and stir well to evenly coat with oil and butter. Cover and cook for 20 minutes, stirring every five minutes or so, until the onions have softened.
Increase heat to medium-high and add 1/2 teaspoon of salt. Stir and continue cooking for a further 15 minutes or until onions are golden browned, soft and caramelized. (The bottom of the pan will also brown during the cooking process. This is where all of the flavour is).
Stir in garlic and cook for one minute, then add in flour and cook for about 4 minutes to brown slightly. Add wine to deglaze the pan, and scrape up the browned bits stuck on the bottom of the pan. Add in the thyme and simmer wine for 2 minutes until reduced by half.
Add beef stock, bouillon and bay leaf; bring to a boil. Reduce heat to low and gently simmer, partially covered with a lid, for 30-40 minutes.
While the soup is simmering, prepare 1 loaf of cheesy garlic bread, or individually portioned garlic breads.
To serve, taste test and season with a little extra salt and pepper, to taste. Ladle into bowls and top with 1 or 2 slices of cheesy toast.

Notes

BEST WINE IN SOUP

Wine is optional to deglaze the pan and add flavour to the soup. I recommend a dry white or red wine, such as a good quality Pinot Grigio/Gris, Sauv Blanc, Sémillon, Chardonnay, Merlot or Pinot Noir. Generally, if you can't drink it, don't cook with it.

WHAT CAN I USE INSTEAD OF WINE IN FRENCH ONION SOUP?

Replace wine with extra beef broth or stock to substitute.
