With fall on the horizon, chain restos everywhere are churning out pumpkin spice this and apple cinnamon that. But Shake Shack is celebrating the season in an unexpected yet fitting way with the launch of its savory, soul-soothing French onion soup menu. The seasonal lineup—which includes burgers and sides alike—first hit stores on September 12, bringing caramelized onions, garlic Parm fries and, most notably, Shake Shack’s first-ever onion rings nationwide. (If you’re a diehard, you should know that the chain also brought back its fan-favorite coffee milkshake!)
