Description

This Miso French Onion Soup is a comforting twist on a classic French favorite, combining deeply caramelized onions with the umami richness of miso paste. The soup is topped with toasted sourdough and bubbling Gruyere cheese, then broiled to perfection for a deliciously savory and warming dish perfect for cozy nights.

Ingredients

Soup Ingredients

  • 3 tbsp butter
  • 4 yellow onions, thinly sliced
  • ½ tsp salt
  • 3 cloves garlic, minced
  • ½ tsp dried thyme
  • ½ cup white wine
  • 4 cups beef broth
  • 2 tbsp miso paste

Toppings

  • 4 slices sourdough bread
  • ⅔ cup grated Gruyere cheese

Instructions

  1. Caramelize the Onions: Melt the butter in a large pot over medium heat. Add the thinly sliced onions and sprinkle with salt. Cover the pot and let the onions cook for 10-15 minutes until they soften. Remove the lid and continue cooking for about 40 minutes, stirring occasionally, until the onions are deeply caramelized. If the onions start to brown too quickly or stick, add a splash of water and reduce the heat.
  2. Add Aromatics and Deglaze: Stir in the minced garlic and dried thyme, cooking for 2 minutes until fragrant. Pour in the white wine, increase the heat to medium-high, and cook until most of the wine liquid has evaporated, intensifying the flavor.
  3. Simmer the Soup: Add the beef broth and miso paste to the pot and bring to a simmer. Let the soup simmer gently for 10 minutes, stirring occasionally to fully dissolve the miso and marry the flavors.
  4. Prepare for Broiling: Preheat the oven broiler. Ladle the hot soup evenly into four ovenproof bowls placed on a baking sheet. Top each bowl with a slice of sourdough bread, then sprinkle the grated Gruyere cheese generously over the bread.
  5. Broil the Soup: Place the baking sheet under the broiler and broil for 2-3 minutes until the cheese melts, bubbles, and turns golden brown. Keep a close eye to prevent burning. Serve hot and enjoy the rich, savory flavors.

Notes

  • Use a heavy-bottomed pot for even caramelization of onions and to prevent burning.
  • If you prefer a vegetarian version, substitute beef broth with vegetable broth.
  • You can substitute Gruyere with Swiss or mozzarella cheese if preferred.
  • Adjust the thyme quantity based on your taste preference.
  • Keep stirring the onions occasionally to ensure even cooking and prevent sticking.
