The French Onion Soup Burger transforms the beloved bistro classic into handheld form, capturing all the deeply savory, caramelized richness that makes French onion soup so irresistible. This burger features a beef patty smothered in slow-cooked onions, melted Gruyère cheese, and a side of rich beef au jus for dipping—bringing that iconic soup experience to burger night.

The secret to this burger's incredible depth of flavor is patience. The onions are cooked low and slow until they're mahogany-colored and intensely sweet, concentrating their natural sugars and developing complex caramelized notes. When combined with nutty Gruyère cheese and a juicy beef patty, then dunked in savory au jus, each bite delivers that same soul-warming satisfaction as a steaming bowl of French onion soup.

This burger is perfect for cozy dinners, impressing guests with bistro-quality flavors, or whenever you're craving comfort food with a gourmet twist. Serve with shoestring fries and extra au jus for the ultimate French-inspired feast.
