Chicago’s iconic deep dish pizzeria marks the milestone with 550 free slices, $19.71 founding year pricing, and a month-long anniversary offer

Lou Malnati’s Pizzeria, a cornerstone of Chicago’s culinary identity, is poised to commemorate a significant achievement on March 17, 2026, marking its 55th year of operation. What began as a single neighborhood eatery in Lincolnwood, Illinois, in 1971, has blossomed into an expansive enterprise encompassing over 70 locations across Chicagoland, Wisconsin, and Arizona. The brand’s enduring success is deeply rooted in its unwavering commitment to crafting handmade deep dish pizzas, celebrated for their signature buttery, flaky crust and a steadfast dedication to utilizing premium quality ingredients. This diamond anniversary not only signifies half a century of culinary excellence but also underscores the pizzeria’s profound impact on local communities and the broader food industry.

Marc Malnati, owner of Lou Malnati’s, articulated the enduring ethos of the establishment, stating, "Even after 55 years, our mission is unchanged. We are committed to handmade quality and to being part of the memories people make around our pizza. The communities and families who have supported us for generations are at the heart of everything we do." This sentiment reflects the deep-seated family values that have guided the business since its inception, fostering a loyal customer base that spans generations. The celebration of this milestone is therefore not merely an internal affair but a public tribute to the customers and communities that have been integral to the Lou Malnati’s journey.

A Legacy Forged in Chicago’s Deep Dish History

To fully appreciate Lou Malnati’s 55-year tenure, one must delve into the rich history of Chicago’s deep dish pizza itself. The invention of this iconic dish is often credited to Pizzeria Uno in the 1940s, evolving as a hearty, casserole-like pizza designed to feed hungry workers. Its distinctive characteristics — a thick, often buttery crust forming a high edge, an inverted layering of ingredients with cheese directly on the crust, followed by toppings, and finally crowned with a rich, chunky tomato sauce — set it apart from its New York-style counterpart. The deep dish became more than just a meal; it became a symbol of Chicago, a culinary ambassador representing the city’s robust and no-nonsense character.

The Malnati family’s connection to this burgeoning pizza scene runs deep, predating Lou Malnati’s establishment. Rudy Malnati Sr., Lou’s father, was a key figure in the early development of Chicago-style deep dish pizza, often credited with helping to create some of the city’s first recipes at establishments like Pizzeria Uno and later founding Pizano’s. Lou Malnati, steeped in this family tradition and possessing an innate understanding of the craft, envisioned his own pizzeria. On March 17, 1971, he opened the doors to Lou Malnati’s Pizzeria in Lincolnwood, Illinois, with a recipe that built upon his family’s heritage while introducing his unique spin, particularly emphasizing a distinct, flaky crust that has become a hallmark of the brand. This founding moment marked the beginning of a legacy that would see the Malnati name become synonymous with Chicago’s quintessential pizza experience, solidifying its claim as the oldest family name in Chicago pizza.

Following this, Wisconsin became the next frontier, with new restaurants opening to enthusiastic reception.

Adding a touch of historical reflection, the pizzeria is offering a special Founding Year Pricing Offer. On March 17 and 18, customers can purchase a large deep dish cheese pizza or an extra-large thin crust cheese pizza for an exclusive price of $19.71. This price point is a direct nod to the year Lou Malnati’s first opened its doors, allowing customers to literally taste a piece of history.
