Iconic Chicago pizzeria Lou Malnati’s has partnered with city favorite Portillo’s to bring back its Lou Malnati’s x Portillo’s Italian Beef Deep Dish pizza, according to a press release.

The pizza is available for retail purchase through Tastes of Chicago or at a Lou Malnati’s restaurant. It debuted last year and became Lou Malnati’s highest-selling LTO pizza.

“When we created the Italian Beef Deep Dish Pizza in partnership with Portillo’s last fall, we knew the pairing of our legendary deep-dish recipe and ingredients along with Portillo’s slow-roasted Italian beef, au jus and peppers was a culinary hit, but we never anticipated it would take off as one of the most buzz worthy and sought after pizzas we’ve ever made,” Marc Malnati, owner of Lou Malnati’s, said in the release. “When people visit the Windy City, Lou Malnati’s and Portillo’s are must visit dining destinations. We are thrilled to bring this now iconic Chicago pizza to customers once again – just in time for holiday gifting and gatherings, whether in Chicago or around the country.”

The pizza is available with either Portillo’s sweet peppers or its hot giardiniera. It features Lou Malnati’s signature crust, vine-ripened plum tomatoes and Wisconsin mozzarella, topped with Portillo’s slow-roasted, thin-sliced Italian beef.

“It doesn’t get more Chicago than Italian beef and deep-dish pizza. The Lou Malnati’s x Portillo’s Italian Beef Deep Dish Pizza is the stuff of icons — we simply had to bring it back,” Michael Osanloo, Portillo’s president and CEO, said in the press release. “Whether you like your Italian Beef with hot giardiniera or with sweet peppers, there is something for everyone in the marriage of our brands.”

Lou Malnati’s operates more than 75 locations in Chicago, Arizona, Indiana and Wisconsin.
