Prep the ingredients: dice the veggies finely and measure out the rice.
Set the Instant Pot to Sauté function on Normal mode. When the display reads "Hot" add the vegetable oil, followed by the vegetables.
Sauté, stirring often, until the vegetables turn soft and begin to stick to the pot. (Don't let them brown.)
Add the rice and sauté for another minute or so. Each rice kernel should be fully coated in oil.
Add the Better Than Bouillon and water. Turn off Sauté function.
Secure the lid onto the Instant Pot, and switch to the Pressure Cook function (Manual on older models). Leave on High Pressure for 15 minutes.
Once the Instant Pot turns off, allow the pressure to naturally release for 10 minutes, then manually release the remaining pressure.
Gently fluff the rice with a spoon or rice paddle.
