Ingredients
- 2 large sweet onions, cut in half and thinly sliced
- Hunk of butter
- 2-3 cups vegetable stock (see notes below)
- 1 TBSP flour, chick pea flour or organic arrow root powder for gluten-free
- 1 tsp balsamic vinegar
- 1-2 cloves garlic, minced
- Freshly ground pepper
- Gruyere cheese, shaved thin or grated
- Salt (maybe)
Instructions
In a dutch oven or a pot big enough for the entire soup, cook the onions in the butter until they start to brown. Add garlic, stock, flour, and vinegar. Stir and cover. Simmer for 15-20 minutes until the stock has thickened and the onions are soft and tender. Sprinkle in some freshly ground pepper.
Fill custard cups or oven safe soup bowls 3/4 inch from to with soup. Top with cheese. Place under broiler until the cheese is melty and browned. Enjoy!
In the picture, I didn’t have gruyere cheese so I used raclette, it melted down in the soup and while it didn’t get all bubbly on the top of the soup like gruyere it was still really good. I also don’t like soggy bread, so instead of putting the cubed bread in the bottom of the soup dish, I toasted it and had it on the side 🙂
Notes:
For the vegetable stock, I save the water from cooking potatoes and other vegetables and can it. I like to use potato water and beet water in this soup.
