Cooking Instructions

  1. 1

    Prepare the Onions

    Begin by slicing the yellow onions thinly. In a large pot or Dutch oven, melt the butter and olive oil over medium heat. Add the sliced onions and a pinch of salt, and sauté for about 20-25 minutes until they are caramelized and golden brown.

  2. 2

    Add Garlic and Thyme

    Stir in the minced garlic and thyme, cooking for another 1-2 minutes until fragrant.

  3. 3

    Deglaze with Broth

    Pour in the broth, scraping the bottom of the pot to release any flavorful bits. Bring the mixture to a simmer and let it cook for about 15-20 minutes. Season with salt and pepper to taste.

  4. 4

    Prepare the Bread

    While the soup is simmering, preheat your oven to 350°F (175°C). Arrange the slices of French bread on a baking sheet and toast them in the oven for about 10 minutes until they are golden and crisp.

  5. 5

    Assemble the Dish

    Ladle the French onion soup into oven-safe bowls. Top each bowl with a slice of toasted French bread and sprinkle with shredded Gruyère cheese.

  6. 6

    Broil the Soup

    Place the bowls under the broiler for about 3-5 minutes, or until the cheese is melted and bubbly. Keep a close eye to prevent burning.

  7. 7

    Serve

    Carefully remove the bowls from the oven and let them cool slightly before serving. Enjoy your homemade roasted French onion soup!
