"The winner has created a pizza with both love and passion, and with a great respect for the ingredients. The winner has pushed the pizza into the top echelons of modern gastronomy," said jury member Tommy Myllymäki in a statement.
Karlsson, who plies his trade as chef at Speceriet in central Stockholm, won with his creation entitled "Tarte flambé à la Karlsson".
Ceveryd competed with "Horseradish luxury" and Tokmark produced "Vitello con Ruccola".
The finalists were selected after a countrywide search for the best candidates and were instructed to make their speciality pizza as well as a more orthodox recipe.
The jury was led by Myllymäki, runner-up in the world chef championships, and Tom Sjöstedt, winner of chef of the year 2008. The panel was completed by 2011 pizza champ Tony Gerasovski and international celebrity chef Michel Arvblom.
Jonas Karlsson expressed satisfaction that the jury shared his ideas about the pizza, one of the most popular dinner dishes amongst Swedes.
"Most people have a relation to the pizza and everyone has their favourite. I want to show with my special pizza that you don't need to use expensive ingredients for it to taste good," he said.
The pizza championships are an annual event organized by Fast Food Magazine in collaboration with a slew of food industry companies.
