This may seem like a fancy name, but it is super easy to make and tastes so good. Your family will love it!
Plus it uses up a ton of red onions if you need that! ;)
- butter or cooking oil
- 2 lbs red onions, sliced
- 1 TBLS balsamic vinegar
- 1 TBLS Worcester sauce
- 1/4 TSP dried tarragon or thyme
- 1/2 cup red wine
- 4 cups chicken, beef, or veg broth
- salt and pepper to taste
- 2 cups grated gruyere cheese
- french baguette slices
- Heat butter or oil in large pot on medium heat.
- Add onions and cover.
- Cook, stirring frequently to prevent burning, until deep golden in color, 15-30 minutes.
- To the onions, add vinegar, Worcester sauce, spices, wine, and broth.
- Bring to a boil and turn down to a simmer. Cook uncovered for 15 minutes.
- Preheat broiler. Ladle soup into oven safe bowls and top with a slice of bread and cheese. Melt cheese under broiler and serve.
