Ingredients
  

For the Soup
  • 4 large yellow onions Sliced, best for sweetness and flavor
  • 2 tablespoons unsalted butter For sautéing the onions
  • 6 cups beef or vegetable broth Low-sodium is preferable
  • 1 teaspoon salt Adjust based on broth saltiness
  • 1 teaspoon black pepper To taste
For the Topping
  • 4 slices sturdy bread Baguette or sourdough works best
  • 1 cup Gruyère cheese Shredded, for melting over the soup

Method
 

Prepare the Onions
  1. Melt butter in a large pot over medium heat.
  2. Add sliced onions and cook, stirring often, until they become soft and translucent.
  3. Continue to cook, stirring frequently, for about 30-40 minutes until the onions are deeply caramelized.
Make the Soup
  1. Add the broth, salt, and pepper to the caramelized onions. Bring the mixture to a boil.
  2. Reduce heat and let it simmer for 20 minutes to deepen the flavors.
Assemble and Serve
  1. Preheat the oven to broil.
  2. Ladle the soup into oven-safe bowls and top each with a slice of bread.
  3. Sprinkle Gruyère cheese generously over the bread.
  4. Place the bowls on a baking sheet and broil for 3-5 minutes until the cheese is bubbly and golden.

Notes

For best flavor, allow onions to caramelize slowly. Consider using a combination of beef and vegetable broth for a richer taste. Serve with a crisp green salad for a well-rounded meal.
