Ingredients
- 2 tablespoons butter
- 4 yellow onions (about 1 3/4 pounds), thinly sliced with the grain to hold their shape
- Kosher salt and freshly ground black pepper
- 1 teaspoon flour
- 1/2 cup dry red wine
- 1 tablespoon chopped fresh thyme
- 1 bay leaf
- 1 teaspoon lemon juice
- 2 cups beef stock
- 2 cups chicken stock
- 1/2 cup grated Swiss
- 1 tablespoon grated Parmesan
- 4 (1-inch thick) baguette slices, cut on the bias
Directions
In a heavy bottomed Dutch oven or large saucepan, melt the butter over medium-low heat. Add the onions, sprinkle with salt, cover, and cook until deeply caramelized, 1 to 1 1/2 hours. Turn the heat up to medium and sprinkle the onions with the flour. Stir and allow to cook for 1 or 2 minutes. Deglaze the pan with the red wine. Add the thyme, bay leaf, lemon juice, and stock and simmer for 10 minutes. Taste and add salt and pepper, as needed. Ladle the soup into 4 ovenproof crocks.
Heat the broiler to high. Mix the cheeses together in a small bowl. Top each crock with a baguette slice and evenly distribute the cheese on top of each. Place the crocks under the broiler just until the cheese is bubbly and browning, about 1 minute. Serve hot.

I was not all that impressed with this recipe. The lovely smells permeating the house kind of heightened my expectation for the overall flavor of this soup.

FOUND IT!!! I had been searching for the best french onion soup and this recipe is it! This soup is delicious and I can't wait to make it again. The only thing I changed was the wine, I used white.

Dear Melissa,
This is the first time a simple onion soup got me so exited that I can not stop talking about it and I decide to write something for the very first time on this web page! The last time I had french onion was 10 years ago and since then I thought it was just waste of money to order this soup! Honestly when I decide to give this receipt a try, I was so not sure about it. I tried it last night and my picky 4 years old daughter and I finished by lunch today. It was so so awsome! Thanks a lot for sharing this wonderful mouth watering receipt Melissa . Everybody please give it a try. Remember the key is a Dutch oven pot for slow cooking!
