Description
This French Onion Soup with Gruyere provides a rich and decadent experience with deep onion flavor and gooey cheese crust, ready in under 30 minutes using a streamlined process.
Ingredients
Scale
4 large Yellow Onions
3 tablespoons Unsalted Butter
6 cups Beef Bone Broth
1/2 cup Dry Sherry or White Wine
3 sprigs Fresh Thyme
1 Baguette slice per bowl
1.5 cups Gruyere Cheese, grated
1 teaspoon Balsamic Vinegar
Instructions
- Peel and slice the onions into thin, uniform half-moons
- Melt the butter in a large pot over medium-high heat. Toss in the onions and a pinch of salt. Cover for 5 minutes to let them sweat
- Remove the lid, raise the heat, and add two tablespoons of water each time the bottom of the pot gets dark brown. Repeat until onions are dark mahogany, about 10-12 minutes
- Pour in the sherry or wine, scraping the bottom to release flavorful brown bits
- Add the beef broth, thyme, and balsamic vinegar. Bring to a boil, then reduce heat and simmer for 10 minutes
- Toast bread slices under the broiler for 1 minute per side
- Ladle soup into oven-safe crocks, place a toasted bread slice on top, and add gruyere cheese. Broil for 2-3 minutes until cheese is bubbly
- Serve immediately while hot
Notes
Use a mandoline for consistent onion slices to save prep time.
Ensure cheese reaches the edges of the bowl for better sealing.
