The Boglio brothers and the invention of stuffed pizza
Giordano's origin story begins with the Boglio family in Torino, Italy. The family emigrated from Italy to Argentina in the post-World War II period, settling in Buenos Aires where Efren and Joseph Boglio grew up. By the late 1960s the brothers had decided to emigrate to the United States, settling in Chicago in the early 1970s with limited English-language skills and modest resources. The decision to open a pizzeria came from family kitchen traditions; the brothers had grown up cooking what they called "Mama's recipe" — a layered stuffed pie from Torino that combined a double crust with cheese stuffing and tomato sauce on top.
The first Giordano's opened in 1974 on the south side of Chicago. The brothers introduced their Italian-family stuffed pizza recipe to the Chicago market at a moment when Chicago deep-dish was already established as a regional pizza tradition but the stuffed-pizza variant had no prior local presence. The novelty of the format — the dramatic cheese-pull from the deeply layered structure, the substantial volume of cheese, the inverted tomato-sauce-on-top arrangement — resonated with Chicago diners and the restaurant grew steadily.
By the 1980s Giordano's had expanded to multiple Chicago-area locations and was firmly established as one of the city's defining pizzerias. The Boglio brothers sold the chain in the 2010s; subsequent ownership transitions and a brief bankruptcy reorganization have not significantly altered the menu, the recipes, or the restaurant atmosphere. Giordano's currently operates more than 75 locations across multiple states, with the Chicago-area locations remaining the brand's identity center.
