Description

This vegan-friendly French Onion Soup recipe offers a comforting and deeply flavorful dish made by slow-cooking caramelized onions in a vegetable broth base, enhanced with white wine and herbs, then topped with toasted baguette slices and melted cheese under the broiler for a golden finish.


Ingredients

Scale

Main Ingredients

  • 4 large onions, thinly sliced
  • 2 tablespoons olive oil or vegan butter
  • 1 teaspoon sugar
  • 4 cups vegetable broth
  • 1 cup dry white wine (optional)
  • 1 teaspoon dried thyme
  • Salt and pepper to taste

Topping

  • Baguette slices for topping
  • Vegan or traditional shredded cheese


Instructions

  1. Prepare onions: Add thinly sliced onions, olive oil or vegan butter, and sugar to the crockpot.
  2. Caramelize onions: Cook on high for 4–5 hours or on low for 8–10 hours, stirring occasionally until the onions are deeply caramelized and golden brown.
  3. Add broth and seasonings: Pour in vegetable broth, white wine if using, dried thyme, salt, and pepper. Cover and cook on low for 1–2 hours to meld the flavors.
  4. Preheat broiler: When ready to serve, preheat your oven’s broiler to high.
  5. Assemble soup bowls: Ladle the hot soup into oven-safe bowls, place a slice of baguette on top of each, and generously sprinkle with shredded cheese.
  6. Broil: Place the bowls under the broiler for 2–3 minutes, or until the cheese is melted, bubbly, and slightly browned.
  7. Serve: Carefully remove from oven and serve the French Onion Soup hot and enjoy the rich, savory flavors.

Notes

  • You can substitute vegan butter for olive oil to keep the recipe vegan.
  • Adjust sugar to help with caramelization depending on onion sweetness.
  • The white wine is optional but adds depth; substitute with more broth if preferred.
  • Use oven-safe bowls for broiling the soup with cheese topping.
  • If you want a gluten-free version, use gluten-free bread for the topping.
