Azzip Pizza, an 11-location chain based in Indiana, is bringing East Coast summer vibes to the Midwest with its latest Pizza of the Month: the Shell Yeah! lobster roll pizza.

Launching July 1, the Shell Yeah! swaps the classic split-top bun for Azzip’s buttery, crispy Detroit-style Square Zip crust, topped with real Maine lobster, mozzarella, Old Bay butter sauce, lemon pepper, Ruffles chips and chives. It is also notably served with a side of warm drawn butter.

The pizza will retail for $15.95, and it marks the first time Azzip has ever used of a premium protein like lobster. The Shell Yeah! is available throughout July at all Azzip locations in Indiana and Kentucky.

“I’m really excited to showcase a premium product like lobster at an approachable price in a fast-casual setting,” said Azzip Chef Blake Kollker. “Enjoying a fresh lobster roll on the beach is one of the best parts of summer, and we’re offering that to people in the Midwest who may not get to the coast.”

“Our guests love when we get really creative and fun with the POTM,” said Azzip founder Brad Niemeier. “This one definitely checks all the boxes.”

At Azzip, the Pizza of the Month (POTM) isn’t just a new topping combo—it’s a creative playground for Kollker, Niemeier and Azzip’s customers alike. Developed by Kollker, the rotating monthly special has become a fan-favorite amongst Azzip’s loyal following, drawing repeat visits and frequently accounting for a significant chunk of monthly sales. From the March Crabness (a crab rangoon pizza that now makes up 30% of sales each March) to burnt ends-laden brisket pies, the POTM is where Kollker’s culinary background shines through.

“If we can put it on a pizza, it’s going on a pizza,” founder Brad Niemeier likes to say—and he means it.

The POTM also powers their loyalty club: diehards can subscribe annually to get each month’s creation, plus a say in what comes next.

Azzip was founded by Brad Niemeier in 2014 after he won Purdue University’s Burton D. Morgan Business Plan Competition with the concept for a build-your-own fast-casual pizza restaurant. Inspired by a Seinfeld clip and driven by a gap in the market, Niemeier turned his $20,000 prize into a growing, family-run brand that now spans Indiana and Kentucky—with more locations on the way.
