Attempting to make a vegetarian French onion soup is a challenge because most versions rely on beef broth. Red wine, tomato paste, and fresh herbs flavor this soup. Don't be tempted to use sweet yellow onions - besides being too sweet, they're also watery.

How to Make It

Step 1

Melt the butter in a large Dutch oven coated with cooking spray over medium heat. Add the onions, salt, and pepper; cover and cook over low heat 30 minutes or until onions are browned, stirring occasionally.

Step 2

Increase heat to medium-high; stir in wine and tomato paste. Cook until wine almost evaporates (about 5 minutes). Add water, tomatoes, rosemary, thyme, parsley, and bay leaves; bring to a boil. Cover, reduce heat, and simmer 20 minutes. Stir in soy sauce; discard parsley and bay leaves.

Step 3

Preheat broiler.

Step 4

Ladle 1 1/3 cups soup into 6 ovenproof bowls. Place bowls on a baking sheet. Top each serving with 1 bread slice, and sprinkle each bread slice with 2 tablespoons Gruyère and about 1 tablespoon Asiago. Broil 3 minutes or until cheese melts.
