Can it sit out?
Sesame oil is shelf-stable, so sitting out at room temperature isn’t the safety question — storage time is.
How to tell if sesame oil has gone bad
- The toasted smell replaced by something flat and putty-like
- A scratchy, bitter finish at the back of the throat
- Oil gone cloudy or thickened at room temperature
- A sticky, varnished ring around the neck of the bottle
When in doubt, throw it out.
Toasted sesame oil is a finishing oil, not a frying one — a spoonful off the heat at the end keeps its whole point intact.
