Place the long-grain rice in a saucepan with a lid, pour in the chicken broth, and bring it to a gentle boil over medium heat for about 2 minutes.
Lower the heat to the lowest setting, stir in the butter until melted, cover with a lid, and let the rice cook undisturbed for 15 minutes.
Turn off the heat, stir the rice, cover it again, and let it rest for 5 minutes. Serve warm.
Notes
A Good Pan with a Tight-Fitting Lid: The key to perfectly cooked rice with this method is using a quality saucepan and a well-fitting lid. A proper lid traps the steam inside, ensuring the top layer cooks evenly along with the rest.Don’t Lift the Lid Too Soon: It can be tempting to peek and check if the rice is done, but resist the urge. I always wait until the full cooking time has passed, keeping the lid closed helps the steam do its job and guarantees fluffy, evenly cooked rice.Let It Rest: I always keep the lid on for 5 minutes after cooking; the steam finishes the rice and makes it extra fluffy.Keep It Simple: Chicken broth adds enough flavor on its own, but sometimes I toss in a bay leaf for a gentle boost.
