What They Say...
Soup’s on... in burger form. We took everything you love about classic French onion soup and stacked it between two halves of a toasted Ken’s Artisan seeded brioche bun. Featuring a juicy Wagyu beef patty, velvety onion soup crème fraîche, sweet slow-caramelized onions, and a blanket of melted Swiss and gruyère cheeses. Rich, savory, cheesy, and outrageously satisfying—every bite tastes like your favorite bowl of French onion soup, only better.
