Vegetarian French Onion Soup

Be the first to rate & review!

This vegetarian French onion soup is teeming with onions and shallots that caramelize and add sweet and savory flavor to the soup. Vegetable broth stands in for beef broth, but mushroom broth, with its dark color and earthy flavor, is also a good option.

Ingredients

3 tablespoons extra-virgin olive oil, divided
4 medium sweet onions, thinly sliced (about 8 cups)
2 large shallots, thinly sliced
1 tablespoon chopped fresh thyme
¾ teaspoon salt
¼ teaspoon ground pepper
1 bay leaf
2 tablespoons all-purpose flour
½ cup dry white wine
1 teaspoon vegetarian Worcestershire sauce
8 cups lower-sodium vegetable broth or mushroom broth
6 slices crusty whole-wheat bread
1 ¼ cups shredded Swiss or Gruyère cheese

Directions

Heat 2 tablespoons oil in a large Dutch oven over medium heat. Stir in onions, shallots, thyme, salt, pepper and bay leaf. Cook, stirring often, until the onions are very tender and darkened, 40 to 45 minutes.

Stir in flour; cook, stirring constantly, until the flour is well distributed and darkened about 1 minute. Stir in wine and Worcestershire; cook, scraping up browned bits from the bottom of the pot, until incorporated, about 30 seconds. Stir in broth; bring to a boil over high heat. Reduce heat to low; simmer, stirring occasionally, until slightly reduced, 20 to 30 minutes.

Meanwhile, preheat oven to 400°F. Line a baking sheet with foil. Brush 1 side of bread slices evenly with the remaining 1 tablespoon oil. Arrange the bread, oil-side up, on the prepared baking sheet. Bake until toasted, about 10 minutes. Remove from the oven. Transfer the toasted bread to a plate. Do not turn the oven off.

Remove and discard the bay leaf from the soup. Place 6 ovenproof soup bowls on a clean baking sheet. Divide the soup among the bowls; top evenly with the toast and cheese. Bake at 400°F until the cheese is melted, bubbling and brown, about 10 minutes. Serve immediately.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
