Zuppa di Cipolle (Italian Onion Soup)

Experience the comforting warmth of Zuppa di Cipolle, a traditional Italian onion soup known for its rich, caramelized flavor and rustic simplicity. This dish brings together slow-cooked onions, savory broth, and a hint of wine to create a soul-soothing meal perfect for any season.

Ingredients

• 6 large yellow onions, thinly sliced
• 3 tablespoons olive oil
• 2 tablespoons butter
• 2 cloves garlic, minced
• 1 teaspoon sugar
• 1/2 cup dry white wine
• 6 cups beef or vegetable broth
• 1 teaspoon salt (or to taste)
• 1/2 teaspoon freshly ground black pepper
• 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
• 1 baguette, sliced and toasted
• 1 cup grated Parmesan or Gruyère cheese

Instructions

1. Caramelize the Onions

   In a large pot, heat the olive oil and butter over medium heat. Add the sliced onions and cook, stirring often, until they become soft and golden brown—about 30 to 40 minutes. Sprinkle with sugar to help with caramelization.

2. Add Garlic and Wine

   Add the minced garlic and cook for another minute. Pour in the white wine and stir, scraping up any browned bits from the bottom of the pot. Let the wine simmer for about 5 minutes until mostly reduced.

3. Simmer the Soup

   Add the broth, salt, pepper, and thyme. Bring to a boil, then reduce the heat and let it simmer gently for 20–25 minutes, allowing the flavors to meld together.

4. Prepare the Topping

   While the soup simmers, toast the baguette slices until crisp. Sprinkle each slice with grated cheese and broil until the cheese is melted and bubbly.

5. Serve

   Ladle the hot soup into bowls and top each serving with a slice of cheesy toast. Alternatively, place the toast directly on top of the soup before broiling for a gratinéed finish.

Serving

Serve Zuppa di Cipolle hot, garnished with a sprinkle of fresh thyme or extra cheese if desired. Pair it with a crisp green salad and a glass of white wine for an authentic Italian dining experience.

Embrace the rustic charm of Zuppa di Cipolle - a comforting bowl of warmth and depth that captures the essence of Italian home cooking.
