Papa doesn’t always know best.

Papa John’s has not changed its recipes despite its namesake founder’s binge-fueled claims that the pies have gotten worse, the pizza chain’s CEO said.

“Nothing has changed,” chief executive Rob Lynch said in a CNBC interview published Wednesday. “I’ve never been a part of a system that takes more pride in what goes into the food that we’re making and how we’re making it. So we feel great about the food that we’re putting out there.”

Lynch was responding to criticism from his predecessor John Schnatter, who said last week that his former firm’s food “just doesn’t taste as good” — a conclusion he reached by eating 40 pizzas in a month.

Schnatter stepped down as CEO last year after he stoked controversy by criticizing NFL leadership over national anthem protests. He left his post as chairman months later after using the N-word on a conference call.

Schnatter has attacked the company he launched in recent months while saying he was only paraphrasing someone else when he used the racial slur.

“Papa John’s management may be emphasizing cost-cutting over product quality,” Schnatter wrote in a Post op-ed in October. “Even the pizzas don’t appear to be made the way that I made them just a few years ago.”

But the company has turned around since Schnatter’s departure. Its stock price has risen more than 50 percent year-to-date, with the sharpest climb coming since Lynch replaced longtime executive Steve Ritchie in August.

Lynch said the company doesn’t pay much attention to Schnatter’s feedback.

“Mr. Schnatter is entitled to his opinion,” Lynch said on CNBC. “We’re focused on doing the things that are gonna move the business forward.”
