French Onion Soup - Easy Slow Cooker RecipeIngredients

  • 5 large onions, thinly sliced
  • 1/4 cup unsalted butter
  • 1 tablespoon sugar
  • 4 cups beef broth
  • 1 cup dry white wine (optional)
  • 1 teaspoon Worcestershire sauce
  • Salt and pepper, to taste
  • French bread, sliced
  • 2 cups shredded Gruyère cheese

Instructions

  1. In your slow cooker, add the sliced onions and butter. Toss them together and cover the slow cooker.
  2. Cook the onions on low for about 10 hours until they are caramelized and golden brown.
  3. After the onions have cooked down, add the sugar, beef broth, white wine (if using), Worcestershire sauce, salt, and pepper. Stir well to combine.
  4. Cover the slow cooker again and cook on low for an additional 2 hours. Taste and adjust seasoning if necessary.
