Instructions
- Heat butter and oil in a large cast iron pot over medium heat. Add onions and stir every 4 minutes initially, and every 2 minutes towards the end until the onions have caramelized into a rich brown/golden color. Lower heat if onions are browning too quickly. The process will take 45 to 60 minutes.
- Once onions are caramelized, add wine, broth, garlic, bay and thyme. Let zimmer for an hour.
- At the end of zimmering, add vinegar, salt and pepper to taste. Remove thyme sprigs and bay leafs.
- Ladle soup into casseroles, and cover top with bread slices. Sprinkle each casserole generously with Gruyère. Broil until cheese melts and browns.
