Caramelized Onion and Parmesan Cheese Soup with Parmesan Cheese Toasts

Caramelized Onion and Parmesan Cheese Soup with Parmesan Cheese Toasts

  • Prep Time: 20 minutes
  • Total Time: 1 hour 20 minutes
  • Yield: 6 servings


  • 2 tablespoons olive oil
  • 2 cups chopped yellow onions
  • 8 to 12 garlic cloves, smashed, plus 1 tablespoon minced garlic
  • 2 bay leaves
  • 1 teaspoon salt, or more to taste
  • 1/2 teaspoon freshly ground black pepper, or more to taste
  • 2 quarts Chicken Stock or canned low-sodium chicken broth
  • 2 teaspoons minced fresh thyme
  • 2 cups 1-inch cubes crusty French or Italian bread
  • 1/2 cup heavy cream
  • 1/2 cup freshly grated Parmigiano-Reggiano
  • 1 tablespoon minced fresh flat-leaf parsley
  • Parmesan Cheese Toasts


  • Heat the oil in a large heavy pot or Dutch oven over medium-low heat. Add the onions, the smashed garlic cloves, bay leaves, salt, and pepper. Cook, stirring often, until the onions are softened and golden, 10 to 15 minutes. Add the minced garlic and stir until fragrant, about 1 minute. Stir in the stock and thyme and bring to a boil. Reduce the heat to medium-low. Simmer, stirring occasionally, for 1 hour.

  • Add the bread cubes. Cook, whisking often, until the bread disintegrates and thickens the soup, about 10 minutes. Remove and discard the bay leaves. Purée the soup with an immersion blender or in batches in a food processor or blender. Return to the pot and whisk in the cream, cheese, and parsley. Season with additional salt and pepper if necessary.

  • Ladle into bowls. Serve with the hot cheese toasts.
