An Alassane N'Diaye strike midway through the second half gave Palace a 1-0 victory at Hayes Lane on Thursday night in their latest pre-season friendly.
New signing Stern John started the match in attack alongside loanee Freddie Sears, while there were also starts for Neil Danns, Nick Carle and Shaun Derry, with the back four made up of Clint Hill, Patrick McCarthy, Jose Fonte and Nathaniel Clyne.
It was a game of few chances, though Bromley came close to opening the scoring in the first half when a long-range effort struck Julian Speroni's crossbar.
The Eagles then hit the woodwork themselves later in the half through Danns.
The win was Palace's fifth in pre-season. They entertain Gillingham on Sunday.
