Ingredients
  

Soup Base

  • 6 cups yellow onions thinly sliced
  • 3 tbsp extra virgin olive oil
  • 0.5 tsp salt
  • 0.25 tsp black pepper

Seasonings

  • 2 cloves garlic minced
  • 1 tsp fresh thyme chopped
  • 1 tbsp balsamic vinegar
  • 1 tbsp brown sugar
  • 1 bay leaf

Liquids

  • 0.5 cup dry white wine
  • 6 cups vegetable broth low-sodium

Toppings

  • 4 slices baguette
  • 1 cup vegan cheese shredded

Instructions
 

Soup Base

  • Heat olive oil in a large pot over medium. Add onions, salt and pepper, stirring every few minutes until golden brown, about 35–40 minutes.

Seasonings

  • Add garlic and thyme, cook 1 minute. Stir in balsamic vinegar and brown sugar, scraping up browning bits, then cook 1–2 minutes.

Liquids

  • Pour in white wine to deglaze, simmer 2 minutes. Add broth and bay leaf, bring to a boil, then simmer 15 minutes. Remove bay leaf and adjust seasoning.

Toppings

  • Preheat broiler. Ladle soup into oven-safe bowls, top with baguette and vegan cheese. Broil until cheese bubbles, 3–5 minutes, then let rest 2 minutes.

Notes

Let soup rest 2 minutes after broiling to avoid burns and achieve a crispier cheese topping.
Skim foam during the first simmer for a clearer broth and add a splash of water if onions start to stick.
