Main Ingredients

Toppings

Method

Preparation

  1. 1

    Prepare the Onions

    Slice the yellow onions thinly, about 1/8 inch thick. This will help them caramelize evenly.

  2. 2

    Sauté the Onions

    In a large skillet over medium heat, melt the unsalted butter. Add the sliced onions and a pinch of salt. Cook, stirring frequently, until the onions are golden brown and caramelized, about 25-30 minutes.

Cooking

  1. 3

    Prepare the Broth

    Once the onions are caramelized, add the dry white wine to the skillet, scraping up any browned bits from the bottom. Let it simmer for 5 minutes until reduced slightly.

  2. 4

    Combine Ingredients

    Transfer the caramelized onions to a slow cooker. Add the beef broth, fresh thyme leaves, bay leaves, black pepper, and additional salt to taste.

  3. 5

    Cook

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

Serving

  1. 6

    Prepare the Baguette

    While the soup is cooking, slice the baguette into 1-inch thick slices. Toast the slices until golden brown.

  2. 7

    Assemble the Dish

    Once the soup is ready, ladle it into oven-safe bowls. Top each bowl with toasted baguette slices and sprinkle with Gruyère and Parmesan cheese.

  3. 8

    Broil

    Place the bowls under the broiler for 2-3 minutes until the cheese is bubbling and golden.

  4. 9

    Serve

    Carefully remove the bowls from the oven and let cool slightly before serving. Enjoy your French Onion Crock!
