The Saracens pivot was moved to fly-half after club-mate Charlie Hodgson, who started against Italy and Scotland, suffered a finger injury.
Hodgson has returned to fitness for the vital Six Nations clash but has been confined to the bench with Farrell continues to pull the strings at 10.
Elsewhere Manu Tuilagi continues in the centre, alongside Brad Barritt, while Tom Palmer takes a place among the replacements following Courtney Lawes leg injury.
"It was a forced change going into the Wales game but it was a chance to seen Owen, Brad and Manu together and I felt they delivered," said Lancaster.
"They played well and there was no reason to change it really.
"Lee Dickson also deserves to keep his spot for the tempo he brings.
"The back three got themselves into the game more and we think they will play a big part at the weekend, with France giving us plenty of ball in terms of kicking."
England: Ben Foden; Chris Ashton, Manu Tuilagi, Brad Barritt, David Strettle; Owen Farrell, Lee Dickson; Alex Corbisiero, Dylan Hartley, Dan Cole; Mouritz Botha, Geoff Parling; Tom Croft, Chris Robshaw (captain), Ben Morgan.
Replacements: Rob Webber, Matt Stevens, Tom Palmer, Phil Dowson, Ben Youngs, Charlie Hodgson, Mike Brown.
