French Red Onion Soup

Have you ever thought about making French onion soup with red onions? I did, and finally decided to give it a whirl. I also added red wine and some more strong flavors like balsamic vinegar. It was amazing and well worth trying.

1 1/2 lbs red onions, sliced in 1/2 inch wedges
1/2 lb sweet yellow onions, sliced in 1/2 inch wedges
2 tablespoons butter
2 tablespoons olive oil
1 tablespoon balsamic vinegar
1 tablespoon Worcestershire sauce
1/4 teaspoon dried tarragon
1/4 teaspoon freshly cracked black pepper
2 cups chicken broth
2 cups beef broth
1/2 cup red wine

To garnish
1 fresh baguette
2 cups freshly grated Gruyere cheese


1. Preheat a large soup pot. Add olive oil and butter, and then onions. Cover with a lid and cook over medium heat until browned, stirring frequently to prevent burning, about 20 – 30 minutes.

2. When onions are browned, add balsamic vinegar, Worcestershire sauce, dried tarragon, freshly cracked black pepper, chicken broth, beef broth and red wine. Bring to a boil and cook over medium heat for 15 – 20 minutes.

3. Preheat broiler. Spoon soup into oven safe bowls and top with a slice of baguette and 1/2 cup cheese. Melt cheese under broiler and serve.

    Well, no actually, I haven’t ever thought of it…but I like the idea and really like your additions of red wine and balsamic vinegar. One thing that fascinates me about cooking is that the more you cook, the more adventurous your ideas become. You are cooking more than ever and it’s so cool to see what you’re coming up with! I always read your recipe ideas through other vehicles these days (email, fb, babble) so I feel like I never come visit you anymore. I need to start coming back to your blog. It feels more like a real visit. Hope you’re well!!
