Boil the water either on top of the stove or in the microwave. For 1 cup of rice, I put my water in a 2-cup measuring cup and heat it in the microwave on high for 3-4 minutes until boiling.
While the water is heating, rinse your white rice by putting it in a colander and running it under cold water until the water runs clear. (If using brown rice, skip this step.)
Pour the rice into a pot that is big enough to hold 4x the amount of rice you use.
Add the salt, pepper, and butter to the rice.
Pour the boiling water into the rice and give the rice a stir.
Cover the rice with a well fitted cover or tightly with aluminum foil.
Bake at 375F degrees for 1 hour for brown rice or 25 minutes for white rice.
Remove the cover and fluff the rice. Serve hot.
Notes
NOTE: To double the recipe, simply double the ingredients and bake it for the same amount of time (don't double the time). Be sure that the pot you choose can accommodate 4x the amount of dry rice you cook.
