Method

Soup Directions

  1. 1

    Prepare the Onions

    Slice the onions thinly. The key to good onion soup is to caramelize the onions slowly.

  2. 2

    Cook the Onions

    In a large pot, melt the butter over medium heat. Add the sliced onions and cook for about 30-40 minutes, stirring frequently, until they are caramelized and golden brown.

  3. 3

    Add Garlic

    Add minced garlic to the pot and cook for an additional 2-3 minutes until fragrant.

  4. 4

    Add Broth and Spices

    Pour in the beef broth, add thyme, bay leaf, salt, and pepper. Bring to a gentle simmer and let it cook for about 30 minutes.

  5. 5

    Adjust Seasoning

    Taste the soup and adjust seasoning if necessary, adding more salt or pepper to taste.

Crostini Directions

  1. 6

    Slice the Baguette

    Cut the baguette into 1/2 inch slices.

  2. 7

    Prepare Crostini

    Preheat your oven to 400°F (200°C). Arrange the baguette slices on a baking sheet, brush with olive oil, and sprinkle with garlic powder.

  3. 8

    Bake the Crostini

    Bake in the preheated oven for about 10-12 minutes, or until they are golden and crispy.

Topping Directions

  1. 9

    Prepare the Cheese

    Shred the mozzarella cheese if using a block.

  2. 10

    Assemble the Soup

    Remove the bay leaf from the soup. Ladle the soup into bowls, top with shredded mozzarella cheese.

  3. 11

    Broil the Cheese

    Place the bowls under a broiler for 1-2 minutes until the cheese is melted and bubbly.

  4. 12

    Garnish

    Garnish with fresh parsley before serving.
