  • 1 baguette sliced in 1/2-3/4-inch rounds
  • 1/2 cup butter
  • 2 cloves garlic minced
  • 2 5- inch sprigs fresh thyme or 1/2 teaspoon dried thyme
  • 1 cup white wine I like my French Onion Soup slightly on the sweet side: Reisling works very nicely for me
  • 3 tablespoons flour
  • 4 medium onions caramelized
  • 4 cups vegetable broth I use 4 cups of water plus 3 teaspoons of "Better Than Bouillon" Vegetable Base
  • 6 ounces Gruyere grated (Provolone works nicely too)


  • Melt the butter in a large pot over medium heat. Add the garlic, thyme, and salt and pepper and sauté for a few seconds, until you can smell the garlic sautéing. Remove from heat.
  • (If you don't have caramelized onions already prepared, add four sliced medium onions to the herb-butter mixture now and continue to cook over medium-low heat until very soft and caramelly. This will take no less than one hour. Don't rush it or your onions may turn out bitter.)

Prepare Baguette Croutons:

  • Arrange the baguette slices on a baking sheet in a single layer. Brush lightly with the garlic-herb butter from the pot. Set under broiler just long enough to toast lightly. Flip the baguette rounds over and repeat. Set aside.

Prepare Soup:

  • To the remaining herb-butter mixture, add the caramelized onions and cook until the mixture is hot and there is very little liquid, about 5 minutes. Add the wine, bring to a boil, reduce the heat and simmer until the wine has evaporated and the onions are nearly dry, about 5 minutes. If you used fresh thyme, discard the thyme sprigs. Sprinkle the flour over the onions and stir to combine. Reduce the heat to low and cook for about 5 minutes, stirring frequently. (This is to cook out the raw flour taste.) Now add the vegetable stock, return to a simmer, and cook for another 5 to 10 minutes. Season, to taste.


  • When you are ready to serve, ladle hot soup into oven-safe bowls and float several of the prepared baguette croutons on top. Sprinkle with grated gruyere and place under broiler just long enough to melt and slightly brown the cheese.
