Add rice and broth to the Instant Pot and stir to combine.
Cover and lock lid into place. Set the valve on the top of the lid to “Sealing."
Select the “Manual” and “High Pressure” settings.
Adjust cook time to 22 minutes. The Instant Pot will come to pressure and then cook for 22 minutes.
Once cook time is complete, allow pressure to release naturally for 10 minutes.
Then do a quick release by carefully turning the sealing valve to either side for any remaining pressure.
Remove lid and stir in lime juice, lime zest, cilantro, and garlic powder. Season with salt and black pepper, to taste, and stir to combine.
If desired, allow flavors to combine for several minutes before serving.
