Toulouse booked their place in a Top 14 final for the first time since 2012 after they overcame La Rochelle in Bordeaux.
Toulouse saw off La Rochelle 20-6 to claim the first spot in the Top 14 final on Saturday.
Not since winning the title in 2012 had Toulouse reached a final, but they are just one victory away from lifting the trophy again.
Sofiane Guitoune put them in front with a try in the 13th minute, with Thomas Ramos adding the extras.
Two penalties within five minutes from Ihaia West brought La Rochelle to within a point of Toulouse at the interval, but the game was taken away from the European Challenge Cup runners-up in the second half.
Sebastien Bezy crossed on the hour-mark and another try from Cheslin Kolbe followed within five minutes.
Bezy added further gloss with a penalty in the 73rd minute, as Toulouse secured their first Top 14 final appearance in seven years, with Clermont Auvergne or Lyon - who play on Sunday - their opponents.
