Leeds took out their frustration at last week's hammering by St Helens by thrashing the Catalans at Headingley.
The Rhinos scored three tries in the first 10 minutes and had three more on the board by half-time, full-back Jordan Tansey completing a hat-trick.
Thomas Bosc and Justin Murphy did cross for Catalans but there was no let-up in the second half as their inaugural Super League season ended in a rout.
Leeds added four more tries to approach the play-offs in better heart.
Danny Williams grabbed a couple, while Scott Donald, Gareth Ellis, Keith Senior, Danny McGuire and James Jones-Buchanan all got in on the act.
Kevin Sinfield (seven) and Rob Burrow (three) converted all 10 tries between them.
McGuire's try on his return from six weeks out was his 24th of the season, but Murphy's score for the the visitors took him to 25, and he is now favourite to finish top try-scorer.
St Helens winger Ade Gardner needs to score a hat-trick of tries against
Warrington on Sunday to draw level with the Australian.
Leeds coach Tony Smith:
(on Danny McGuire, who he replaced in the final quarter)
"He missed out on his top try-scoring feat, but I did not want him to run out
"There are bigger things that Danny would like to pick up this year. He is a proven try-scorer - he's done it year after year and he'll do it for years to come.
"He came through well, but tomorrow is going to be the real big test. He felt fine and looked sharp. We've missed him."
(on 20-year-old Jordan Tansey)
"To score a hat-trick in Super League is quite an achievement for anybody but for someone so young and still gaining experience, I'm delighted for him."
Catalans coach Mick Potter:
"I thought Leeds played very well. They executed some really good plays and caught us wide out.
"We had a lot of young French players out there, and I thought they applied
themselves. There were some encouraging signs, but we handed the ball over far too often.
"I'm very pleased for Justin (Murphy). It's great for where we are sat in the league (bottom) for him to lead the try-scoring list. It's phenomenal for him personally and shows that we are a team who can score tries."
