Each spoonful is cozy, cheesy, and deeply savory, making it a perfect dish for chilly evenings or a warm holiday starter.

Ingredients

  • 2 tablespoons butter

  • 2 tablespoons olive oil

  • 3 large yellow onions, thinly sliced

  • 2 cloves garlic, minced

  • 1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)

  • ½ teaspoon salt

  • ¼ teaspoon black pepper

  • ½ cup dry white wine (optional)

  • 4 cups beef broth

  • 1 cup water

  • 1 teaspoon Worcestershire sauce

  • 1 pound potato gnocchi

  • 1 cup shredded Gruyère cheese

  • ½ cup shredded mozzarella or Swiss cheese

  • 2 tablespoons grated Parmesan

  • Fresh parsley, chopped (for garnish)

Cooking Time

  • Cook time: 40 minutes

  • Total time: 50 minutes

Serving

  • Serves 4

Instructions

  1. Caramelize the onions:

    In a large pot, heat butter and olive oil over medium-low heat. Add sliced onions, salt, and thyme. Cook for 25–30 minutes, stirring often, until the onions are soft, golden brown, and caramelized.

  2. Deglaze the pot:

    Add garlic and cook for 1 minute. Pour in white wine (if using) and stir, scraping up any browned bits from the bottom. Simmer for 3 minutes until the liquid slightly reduces.

  3. Build the soup base:

    Stir in beef broth, water, black pepper, and Worcestershire sauce. Bring to a simmer and cook for 10 minutes to deepen the flavor.

  4. Add the gnocchi:

    Stir in the gnocchi and cook for 3–4 minutes until they float to the surface and are tender.

  5. Add cheese:

    Turn off the heat and stir in Gruyère, mozzarella, and Parmesan until melted and creamy. Adjust seasoning with salt and pepper if needed.

  6. Serve:

    Ladle into bowls, sprinkle with extra cheese or parsley, and serve hot. For an authentic French onion touch, you can also broil the bowls with extra cheese on top until bubbly and golden.

Tips

  • Use store-bought or homemade gnocchi—either works beautifully.

  • Replace beef broth with vegetable broth for a vegetarian version.

  • For extra flavor, top each serving with toasted baguette slices before adding melted cheese.
