Step 1:

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.

In the prepared baking dish, add the uncooked rice. Pour in the chicken broth and milk, then stir gently.

Remove the foil, sprinkle cheese on top if using, and bake uncovered for an additional 10–15 minutes until melted and bubbly.

Step 11:

Let the casserole rest for 5–10 minutes before serving.
