Mouthwatering French Onion Soup recipe makes a comforting, classic bowl of soup with caramelized onions in rich soup and crusty bread with melty, delicious cheese!
Slice onions thinly. Add onions, salt, and butter to a Dutch oven set over low heat.
Stir occasionally until the onions have cooked down and are a caramel color, about 45 minutes to an hour.
Add garlic and cook until fragrant, about 1 minute.
Then, add the beef and chicken stock and stir. Cover and let simmer for 30 minutes.
Ladle the soup into individual, oven-proof soup bowls.
