Notes
Long grain white rice is recommended as it holds its shape well during the slow cooking process.Avoid quick-cooking or instant rice, as they can become too mushy.Adding the broccoli later in the cooking process ensures it remains vibrant and doesn't overcook. Overcooked broccoli can become mushy and lose its bright green color.Refrigerate the leftovers in an airtight container for up to 5 days.
