Ingredients

Scale

the Soup:

  • 4 large yellow onions, thinly sliced
  • 3 tablespoons butter
  • 1 tablespoon olive oil
  • 2 cloves garlic, minced
  • 1 teaspoon sugar (helps with caramelization)
  • ½ teaspoon salt

Instructions

1: Caramelize the Onions

  1. Heat butter and olive oil in a large pot over medium heat.
  2. Add the sliced onions, salt, and sugar. Cook, stirring occasionally, for 30–40 minutes, until onions are deep golden brown.
  3. Stir in garlic and cook for another 1–2 minutes.

2: Deglaze the Pot

  2. Let it simmer for 3–5 minutes, until the liquid reduces slightly.

3: Simmer the Soup

  1. Stir in flour (if using) and cook for 1 minute.
  2. Add beef broth, Worcestershire sauce, thyme, and bay leaf.
  3. Bring to a simmer and cook for 20 minutes, allowing flavors to meld.
  4. Remove the thyme sprigs and bay leaf before serving.

4: Prepare the Topping

  1. Preheat the oven to 400°F (200°C).
  2. Brush baguette slices with melted butter and bake for 5 minutes until crisp.
  3. Remove from oven and top each slice with shredded Gruyère cheese.

5: Assemble and Serve

  1. Ladle the hot soup into oven-safe bowls.
  2. Place cheese-topped baguette slices on top of each bowl.
  3. Broil for 2–3 minutes until the cheese is melted and bubbly.
  4. Serve immediately and enjoy!
