Description
A comforting, savory soup featuring deeply caramelized onions, rich beef broth, and a decadent topping of toasted baguette and melted Gruyère cheese.
Ingredients
- 1 Tbsp. Sugar
- 4 Tbsp. Butter
- 1/2 Cup Extra beef broth (for deglazing)
- 3/4 Tsp. Dried thyme
- 1 Tbsp. Apple cider vinegar
- 2 Lbs. Yellow onions, halved and thinly sliced
- 12 Oz. Gruyère cheese, grated
- 1 Tbsp. All-purpose flour
- 6 Cups Beef stock
- 12 slices French baguette (3/4-inch thick)
- Fresh Thyme sprigs for garnish
- Kosher salt and freshly ground black pepper to taste
Instructions
- Melt the butter in a large pot or Dutch oven over medium heat. Add the sliced onions and sprinkle with sugar. Cook slowly, stirring often, for about 55-65 minutes until the onions are soft and deep golden brown.
- Sprinkle the flour over the caramelized onions and stir for 1 minute. Add the apple cider vinegar and the extra beef broth to deglaze the pan, scraping up browned bits.
- Pour in the remaining beef stock and add the dried thyme. Bring to a simmer and cook partially covered for 25-30 minutes. Season with salt and pepper.
- Preheat your broiler. Place baguette slices on a baking sheet and toast under the broiler until golden brown on both sides.
- Ladle the soup into oven-safe bowls. Top each with two slices of toasted bread and a generous amount of grated Gruyère cheese.
- Broil the bowls on a baking sheet for 2-3 minutes until the cheese is melted, bubbly, and browned. Garnish with fresh thyme and serve hot.
Notes
This recipe uses apple cider vinegar and extra broth instead of the traditional sherry to keep it alcohol-free while maintaining excellent flavor.
