Ingredients
- 3 lbs sweet onions sliced
- ¼ cup melted unsalted butter
- 1 tbsp brown sugar
- 6 cups unsalted or low-sodium beef broth/stock
- 2 tbsp dry sherry vinegar
- 1 tsp dried thyme
- ½ tsp salt
- ½ tsp black pepper
- 3 garlic cloves minced
- 1 bay leaf
- French Bread
- 1 cup freshly shredded gruyere cheese
Instructions
- Place sliced onions in the slow cooker. Add brown sugar and melted butter. Mix well and cover. Cook on high for 10 hours.
- Remove lid and add garlic, thyme, dry sherry and mix. Add beef broth and bay leaf.
- Cover and cook on high for 2-3 hours. Discard bay leaf. Season with salt & pepper to taste.
Toast bread ~ This is highly recommended but not required. It will be slightly crunchy and not soggy.
- Preheat the oven to 325°F (162°C). Place the sliced bread on a baking sheet and toast 2 minutes per-side or until golden. Remove the bread from the oven.
- Transfer the soup to a bowl(s). Place toast o top. Sprinkle gruyere cheese on top of the bread and soup.
- Return the baking sheet to the oven. Broil on high for 3-4 minutes or until the Gruyere is bubbly and golden brown. Then remove from the oven. Exercise caution: the dish/bowl will be very hot.
- It is highly recommended to pre-toast the bread prior to placing on the soup bowl as it will maintain a better crunch. However if you prefer your bread a bit soggy then you can just place sliced bread and cheese on top of the soup. Broil until the cheese has melted. Again exercise caution: the dish will be very hot.
