French Onion Soup

French Onion Soup is such a classic and SO easy to make! Onions are slowly caramelized until soft and sweet, simmered with beef broth, thyme, sherry, and white wine. It's topped with a crispy crouton, loads of shredded gruyere cheese and broiled into a crispy, cheesy oblivion. So good!

Ingredients

Servings
  • 3 tablespoons unsalted butter
  • 10 cups thinly sliced onions
  • ¾ teaspoon salt more to taste
  • 2 tablespoons all-purpose flour
  • ¼ cup sherry
  • ½ cup dry white wine sauvignon blanc or pinot Grigio
  • 4 cups beef broth
  • 5 prigs thyme
  • 4-8 lices baguette 1-inch slices
  • 8 ounces gruyere cheese

Instructions

  1. Heat a large, heavy-bottomed pot over medium heat. Add 3 tablespoons unsalted butter and let it melt. Add 10 cups thinly sliced onions and ¾ teaspoon salt and stir.
  2. Let the onions sauté for 5-10 minutes or until they begin to turn translucent. Reduce the heat to medium-low and continue to cook the onions for another 45 minutes, stiring every 5-10 minutes to prevent them from burning. If they are burning instead of caramelizing, turn the heat to low and stir more frequently. They should be fragrant and turn a deep golden brown. The size will reduce drastically.
  3. Turn the heat back to medium, stir 2 tablespoons all-purpose flour into the onions, and cook for 1 minute. Slowly stir in 4 cups beef broth , ¼ cup sherry, and ½ cup dry white wine. Bring to a simmer. Simmer until the soup begins to thicken and reduce, about 4-5 minutes. Stir in 5 sprigs thyme. Adjust the salt as needed.
  4. While the onions cook, toast the 4-8 slices baguette pieces in the oven. Brush both sides with olive oil, then bake at 350 degrees Fahrenheit for 6-8 minutes. Flip the bread halfway through. Remove from the oven and set aside.
  5. Ladle the soup into four oven-safe bowls. Place a slice or two of toasted bread on top of the soup and cover with some of the 8 ounces Gruyere cheese. Place the bowls on a large sheet pan and broil until the cheese has melted and started to turn brown and bubbly, about 2-3 minutes. Keep a close eye on them. Some broilers can cook faster than others. Serve immediately.
