French Onion Soup

Cook Time 8 hours

Prep Time 30 minutes


Makes 8 servings


4 tablespoons butter, divided
3 pounds yellow onions, sliced
1 tablespoon sugar
2 to 3 tablespoons dry white wine or water (optional)
2 quarts (8 cups) beef broth
8 to 16 slices French bread
1/2 cup (2 ounces) shredded Gruyère or Swiss cheese


  1. Melt butter in large skillet over medium to low heat. Add onions; cover and cook just until onions are tender and transparent, but not browned, about 10 minutes.
  2. Remove cover. Sprinkle sugar over onions. Cook and stir 8 to 10 minutes or until onions are caramelized. Add onions and any browned bits to 4-quart slow cooker. If desired, add wine to pan. Bring to a boil, scraping up any browned bits with wooden spoon. Add to slow cooker. Stir in broth. Cover; cook on LOW 8 hours or on HIGH 6 hours.
  3. Preheat broiler. To serve, ladle soup into individual soup bowls; top with 1 or 2 slices bread and about 1 tablespoon cheese. Place under broiler until cheese is melted and bubbly.


Substitute 1 cup dry white wine for 1 cup of the beef broth.
