Pour the couscous, water or broth, and a pinch of salt (if using) into the Instant Pot.
If you prefer, you can also add a drizzle of olive oil to enhance the flavor and prevent the couscous from sticking together.
Secure the lid of the Instant Pot and set the timer for 0 minutes on the high pressure. Make sure the vent is set to 'Sealing.'
The Instant Pot will take a few minutes to build pressure before the timer starts.
Once the timer expires, allow 5 minutes of natural release before manually using the quick release option for any remaining pressure.
Fluff the couscous with a fork after a couple of minutes and serve hot.
