Dutch Oven French Onion Soup

Comforting Dutch Oven French Onion Soup

A rich and hearty French Onion Soup made in a Dutch oven, featuring caramelized onions, savory beef broth, and melted cheese on toasted baguette slices.

Ingredients

Scale
  • 4 large yellow onions, thinly sliced
  • 4 tbsp unsalted butter
  • 2 tbsp olive oil
  • 1 tsp sugar
  • 4 cloves garlic, minced
  • 8 cups beef broth
  • 1/2 cup dry white wine
  • 2 bay leaves
  • 1 tsp fresh thyme leaves (or 1/2 tsp dried thyme)
  • Salt and freshly ground black pepper, to taste
  • 1 baguette, sliced
  • 2 cups grated Gruyère cheese

Instructions

  1. In a Dutch oven, heat butter and olive oil over medium heat until melted and hot.
  2. Add the sliced onions and sprinkle with sugar; cook, stirring frequently, until onions are deeply caramelized, about 40-50 minutes.
  3. Add minced garlic and cook for another 2 minutes, stirring constantly.
  4. Pour in the white wine to deglaze the pot, scraping up any browned bits from the bottom.
  5. Add beef broth, bay leaves, and thyme; bring soup to a simmer and cook for 30 minutes. Season with salt and pepper to taste.
  6. While the soup simmers, toast baguette slices until golden brown.
  7. Preheat the oven broiler. Ladle soup into oven-safe bowls, top with toasted baguette slices and generous amounts of grated Gruyère cheese.
  8. Place bowls on a baking sheet and broil until cheese is melted and bubbly, about 3-5 minutes.
  9. Carefully remove from oven and serve hot.

Notes

For an extra depth of flavor, add a splash of brandy or sherry before simmering the soup.
