Recipe Notes
When you add the rice to the Instant Pot, stir it constantly so none of it sticks to the bottom of the pot. If any rice sticks, you'll likely end up with a burn notice during cooking, so make sure to scrape it up with the spatula when you add the chicken broth.
Make it Vegetarian/Vegan: Use vegetable broth instead of chicken broth.
