This easy homemade French Onion Soup is irresistibly delicious topped with a toasted baguette and a thick layer of gooey melted Gruyere!
- 3 tablespoons Butter
- 4 whole Large yellow onions, chopped
- 1 teaspoon Brown sugar (white or raw sugar will work)
- 2 cloves minced garlic
- 1 tbsp Brown rice flour (or all-purpose flour)
- ½ cups White wine (optional but recommended)
- 4 cups Broth or beef broth
- 1 branch Fresh thyme
- 1 whole Baguette
- 1 tbsp Olive oil for brushing
- 1 cup grated cheese
Melt the butter in a Dutch oven or any large saucepan. Add the chopped onions and cook over medium heat until completely caramelized. This process will take approximately 40-45 minutes. Stir occasionally at the beginning and often towards the end. About 38-40 minutes into the process, add the sugar and garlic and continue to stir.
When the onions are medium brown (not burnt) and fully caramelized, add the flour to slightly thicken the broth; stir. Add the wine and, using a wooden spoon, scrape up any bits of onion that may be attached to the bottom of the pan. Add the beef broth, fresh thyme and partially cover the pan, simmering for 15 minutes.
Meanwhile, turn the oven to 400ºF degrees. Slice the baguette and brush each slice with olive oil on both sides. Bake for about 5 minutes or until golden brown and toasted. Remove the baguette from the oven and switch the oven to broil.
Pour the onion soup into an ovenproof bowl. Place 2 slices of toasted baguette on top of the soup and generously cover the baguette and the soup with grated Gruyère cheese. Place the ovenproof bowls on a baking sheet to catch drippings of melted cheese and broil for about 3 minutes or until the cheese is completely melted and delicious!
