Ingredients

Method

Directions

  1. 1

    Prepare the Onions

    Slice the yellow onions thinly. Heat butter and olive oil in a large pot over medium heat. Add the onions and a pinch of salt, cooking until they become soft and caramelized, about 20-25 minutes.

  2. 2

    Add Mushrooms and Garlic

    While the onions are caramelizing, slice the cremini mushrooms. Add them to the pot along with minced garlic. Cook for an additional 5-7 minutes until the mushrooms are tender.

  3. 3

    Deglaze the Pot

    Pour in the sherry or white wine to deglaze the pot, scraping the bottom to release any browned bits. Allow it to simmer for 2-3 minutes.

  4. 4

    Add Broth and Seasoning

    Add the beef or vegetable broth, thyme, salt, and black pepper to the pot. Bring to a boil, then reduce the heat and let it simmer for 15 minutes.

  5. 5

    Finish with Cheese

    Ladle the soup into bowls and top with Gruyère cheese. Place under the broiler for 2-3 minutes until the cheese is melted and bubbly. Garnish with fresh parsley before serving.
