Ingredients
  

4 large yellow onions, thinly sliced

2 tablespoons butter

2 tablespoons olive oil

1 teaspoon salt

1 teaspoon sugar

4 cloves garlic, minced

6 cups beef broth (low-sodium preferred)

1 cup dry white wine (optional)

1 tablespoon fresh thyme leaves (or 1 teaspoon dried)

1 bay leaf

½ teaspoon black pepper

1 French baguette, sliced

2 cups shredded Gruyère cheese

Fresh parsley, chopped (for garnish)

Instructions
 

In a large skillet, melt the butter and olive oil over medium heat. Add the sliced onions and sprinkle with salt and sugar. Cook for about 20-25 minutes, stirring occasionally, until the onions are caramelized and golden brown.

    Add minced garlic to the skillet and cook for an additional minute until fragrant.

      Transfer the caramelized onions and garlic to the crockpot. Pour in the beef broth and white wine (if using). Stir in thyme, bay leaf, and black pepper.

        Cover the crockpot and cook on low for 6-8 hours or high for 3-4 hours, until the flavors meld together.

          About 30 minutes before serving, if desired, toast the baguette slices until they are golden brown in a toaster or oven.

            Once the soup is ready, remove and discard the bay leaf. Taste and adjust seasoning if necessary.

              To serve, ladle the soup into bowls, top with toasted baguette slices, and sprinkle generously with Gruyère cheese.

                Place the bowls under the broiler for 2-3 minutes until the cheese is melted and bubbly. Remove carefully.

                  Garnish with chopped parsley before serving.
