Onion Gruyère soup is the ultimate French onion soup experience. While many recipes use whatever Swiss cheese is available, this version insists on authentic Gruyère - its nutty, slightly sweet flavor is irreplaceable and elevates the soup to special-occasion status.
The key is using generous amounts of quality Gruyère, both melted into the soup and broiled on top. This creates layers of cheesy goodness that stretch beautifully when you dig in.
Why Gruyère?
- Flavor: Nutty, sweet, complex
- Melting: Smooth, not stringy
- Browning: Perfect golden crust
- Origin: Swiss Alps tradition
Gruyère Tips
- Age matters - use aged for more flavor
- Grate fresh for best melting
- Room temperature melts better
- Don't substitute with pre-shredded
Serving Suggestions
