A chain where business is all about moms was just named the best pizza restaurant in America.

Papa Murphy’s ranks as America's favorite pizza chain, according to Market Force Information’s annual quick-service-restaurant study.

This is the third year in a row that Papa Murphy's has snagged the top spot — despite the fact that its sales are nowhere near Papa John's, Domino's, or Pizza Hut's.

Unlike the biggest names in the pizza business, Papa Murphy’s doesn’t sell pizza piping hot and ready to be eaten.

Instead, the pies are never baked — the restaurants don't even have ovens or freezers. Customers buy a raw pie, to be baked at home.

Papa Murphy’s has more than 1,500 locations in 38 states, as well as restaurants in Canada and the United Arab Emirates, making it the fifth-largest pizza chain in the US. It is by far the largest take-and-bake pizza chain in the country — the nearest competitor, Figaro’s Pizza, has fewer than 50 locations.

While chains like Domino’s or Papa John’s appeal to younger, mostly male customers who are hungry for delivery pizza, Papa Murphy’s is focused on marketing to families, something that pays off when it comes to finding loyal customers.

In addition to being named the No. 1 pizza chain by Market Force, Consumer Reports and Nation's Restaurant News have also ranked Papa Murphy's as the top pizza-restaurant chain in the US.

"Young males are not loyal. So a young male typically will love you today, and then when the next pizza place says they can charge nine bucks for that versus 10, they'll go for that," CEO Ken Calwell told Entrepreneur.com. "Moms are hard to get, but moms are really loyal."

In an effort to appeal to families, Papa Murphy’s markets its pizzas as healthier options than the delivery-centric competition. The chain has lower-calorie options on the "Gourmet Delite" menu, cutting calories by serving up pizzas with thin crusts.

On the other side of the calorie spectrum is Papa Murphy’s "stuffed" menu, with sandwich-esque pizzas like Chicken Bacon Stuffed, with one layer of creamy garlic sauce, chicken, bacon, tomatoes, and mixed onions topped with another layer of tomatoes, bacon, provolone, and cheddar.

The menu is completely customizable. The "Create Your Own" platform lets customers pick their own dough, sauce, and toppings combinations.
