Vegan French Onion Soup

1. In a large pot or Dutch oven, melt the butter over medium heat and add the onions. Cook for 20 to 25 minutes, stirring occasionally, until the onions are browned and caramelized. Cook for 2 to 3 minutes more, or until the garlic is fragrant, before adding the garlic, thyme, and bay leaves. Cook, stirring occasionally, until the liquid has been absorbed by the wine. Cook, stirring constantly, until the oat flour is no longer visible, about 2 minutes.
2. Bring the broth to a boil, then remove from the heat. Reduce the heat to low and continue to cook for about 15 minutes, or until the sauce has thickened. Combine the nutritional yeast (if using), salt, and pepper in a mixing bowl. Take the pan off the heat and discard the bay leaves.
3. Preheat the oven broiler. On a baking sheet, arrange six small ovenproof bowls or ramekins. Pour the soup into the serving bowls. 1 or 2 baguette slices should be placed on top of the soup. Spread the cheese sauce on top of the bread. Preheat the broiler while the baking sheet with the bowls is in the oven. Broil the cheese for 3 to 4 minutes, or until it is browned and bubbly. Take the pan off the heat and sprinkle with parsley (if using). Serve right away. Leftover soup can be stored in an airtight container in the refrigerator for 2 to 3 days.

Recipe Notes

Because the cheese sauce will take 5 to 7 minutes to heat, I recommend making it while the soup is simmering.
