Fourcade, who took both the individual and sprint races at the first World Cup in Sweden, suffered his first defeat of the season when he was edged out by Lars Berger in Friday's sprint event.
But he reclaimed top spot on the medal rostrum after finishing in 32:43.3 with just one penalty, 24 seconds ahead of Norway pair Emil Hegle Svendsen in second and Tarjei Boe in third.
In the women's 10k pursuit, Norway's Synnove Solemdal picked up only her second ever career victory in 30:16.2 with one penalty in great biathlon weather conditions.
Going into the closing stages, Solemdal was closely followed by Ukraine's Juliya Dzhyma but after the Norwegian cleaned rapidly on the shooting range, she raced away to win by five seconds.
Poland's Krystyna Palka rouded off the medal positions in third place, just the second podium of her career, after moving away from Veronika Vitkova of the Czech Republic at the 9.3k mark.
