Recipe FAQ
Can I use white onions instead of yellow? Absolutely! White onions bring a milder flavor but still waltz beautifully with the other ingredients.
What’s the best wine for this recipe? A dry red wine like Cabernet Sauvignon adds depth, but feel free to use what you have.
Can I freeze the soup? While the broth freezes well, the texture of the onions may change. Fresh is best, but freezing won’t banish the magic entirely.

- 1 ¼ cup red wine
- 1 Tbsp worcestershire sauce
- 2 Tbsp all-purpose flour
- 8 cups chicken broth
- 1 French baguette sliced
- ½ lb gruyere cheese shredded or sliced
Instructions
- In a large pot, or Dutch oven, melt the butter over medium-high heat. Add the onions and garlic, seasoning generously with salt and pepper. Cook, stirring occasionally, for about 10-15 minutes until onions are softened and beginning to caramelize.
- Add 1 cup of the wine along with the mushrooms and cook, stirring occasionally, for about 10 minutes to soften the mushrooms. Add remaining wine, Worcestershire sauce, and flour then stir to combine; cooking for additional 5 minutes.
- Add the chicken broth to the pot, and season again with salt and pepper. Bring to a boil, then reduce heat and simmer for 10-15 minutes.
- While simmering, preheat the oven to 400° F. Lay your bread slices on a sheet pan and toast in the oven for 4-5 minutes, watching closely to make sure they don't burn. Remove from oven and turn up to broil.
- Once the soup has simmered, ladle into oven-safe bowls and place on a baking sheet. Top the bread with a generous handful of shredded cheese (or a couple slices if using sliced).
- Place the sheet pan of soups into the broiler for 3-4 minutes or until the cheese is fully melted and just starting to bubble and brown.
