Preheat the oven to 350 degrees.

In an 8x8 casserole dish, add the rice, broth, salt, and garlic powder and stir together.

Add the sliced butter evenly over the top of the rice mixture.

Cover the dish with foil and bake for 30 minutes. Uncover and bake for an additional 30 minutes or until the moisture is absorbed and the rice is tender.
