Aurellian beef stew was a foodstuff served aboard USS Voyager by Neelix that was mentioned in a deleted scene cut from the Star Trek: Voyager episode "Friendship One".

In the final draft of the script, it establishes that Neelix was in the middle of describing his day to a photograph of his sister, Alixia, as he prepared for bed. The scene picks up with him explaining that "Ensign Tefler checked into Sickbay with another case of "food poisoning". The Doctor requisitioned my Aurellian beef stew... but he didn't find any pathogens... of course."
