Princess Cruises announced that Alfredo’s Pizzeria aboard the Sun Princess and the Star Princess has been awarded the Ospitalità Italiana Certification, the highest global recognition for authentic Italian cuisine and hospitality.

The certification is awarded only to dining establishments that uphold Italy’s rich culinary heritage, according to the company.

“Earning the Ospitalità Italiana Certification is a meaningful validation of our dedication to authentic Italian culinary excellence,” said Sami Kohen, vice president of food and beverage at Princess Cruises.

“As we celebrate National Pizza Day, we’re proud to recognize this achievement and our partnership with Chef Tony Gemignani to showcase how we bring our guests closer to the tastes, traditions and hospitality of Italy, one perfectly crafted pizza at a time.”

The pizzeria serves Neapolitan-style pizza made to order, hand-stretched and baked in a stone Moretti Forni oven using fresh ingredients and traditional techniques.

Princess Cruises partners with chef Tony Gemignani, a 13-time World Pizza Champion, who has created five unique pizzas served across the fleet of 17 ships.

The pizzas feature ingredients including Soppressata sausage, hot honey, Gorgonzola and sweet fig preserves.

The achievement reinforces Princess Cruises’ recognition by USA Today as offering the Best Pizza at Sea, the company said.

The certification was announced alongside National Pizza Day on Feb. 9.
