Begin by turning your Instant Pot to the Saute function. Add the butter and allow it to melt. Then, pour the couscous into the pot. Stir the couscous around in the butter for 1-2 minutes to allow the couscous to toast. Don’t let it burn!
Turn saute off, and add the chicken broth into the pot. Seal the lid and turn the pot to MANUAL on high. Set the timer for 7 minutes.
When the cook cycle is complete, allow for a 2 minute natural pressure release. Then perform a quick release.
Once you open the lid of the pot, there may still be some liquid with the couscous. This is okay! Turn the pot to the KEEP WARM function, and stir the couscous occasionally until the rest of the liquid is evaporated.
