The wait was on the long side for the pizza - 18 hours - but this was an extraordinary pie measuring 1.59545 kilometres or nearly a mile long.
More than 60 of Italy's best pizza makers worked through the night to create the pizza at Milan's world fair, Expo 2015.
Their toil was rewarded with a proclamation by a Guinness World Records judge that it was the world's longest pizza.
Expo organisers said the record-setting pizza, made with 1.5 tons of mozzarella and two tons of tomato sauce, weighed five tons in all.
The creation topped the record of a 1.1415-kilometre-long pizza made in Spain. Fair-goers could eat slices of the Milan pizza for free.
