Italian beef is not the regular smoked version available everywhere. Each slice is shaved paper-thin to absorb the rich flavors of its seasoned broth. This slow-simmered infusion creates the unmistakable tenderness that makes Chicago’s version stand apart. Without the right cut, the entire sandwich loses its signature texture.

A true Italian beef isn’t complete without giardiniera. This pickled mix of hot or mild vegetables adds a bold crunch and bursts of spice. Chicagoans fiercely debate the best kind: some swear by oil-based varieties, while others prefer vinegar-packed blends. Either way, giardiniera is a non-negotiable topping.
