Ingredients

Instructions

  1. Step 1: Thinly slice 4 large Vidalia onions and melt 3 tbsp butter in a large pot over medium-low heat. Cook onions for 45 minutes, stirring occasionally, until deeply caramelized and golden.
  2. Step 2: Sprinkle 2 tbsp flour over onions and stir for 1 minute to cook off raw flour taste. Gradually whisk in 4 cups chicken broth and 1 tbsp fresh thyme, then simmer for 20 minutes.
  3. Step 3: Preheat oven broiler. Place 6 buttered baguette slices on a baking sheet and top each with 1/8 cup grated Gruyère cheese.
  4. Step 4: Broil slices 3 inches from heat for 2-3 minutes until cheese bubbles and browns.
  5. Step 5: Ladle soup into bowls, top with 1 cheese-topped bread slice, and serve immediately.
