McBreen signed a new one-year contract with Falkirk in June 2005, and manager John Hughes predicted "With a good pre-season under his belt, I'm sure he'll get even better". He scored his first goal of the 2005–06 season in the 83rd minute of a home match against Rangers on 10 September, with a header from Alan Gow's cross that secured Falkirk a 1–1 draw. McBreen scored the only goal in Falkirk's 1–0 win over Livingston on 6 May 2006 with a header from Gow's free kick, which was only the team's second victory at home all season. He appeared more frequently in 2005–06, making 38 appearances but only scoring 8 goals, Despite taking over the main striking role after Duffy's transfer to Hull City in January, McBreen was released by the club in May.
