Begin by preparing 4 servings of brown or white rice per the box instructions.
Then add the cooked rice and sour cream to a medium size mixing bowl and use a wood spoon to mix until the rice is covered with sour cream. Next add 1/2 cup of shredded cheese, jalapeños, salt and pepper to the rice and stir it until the ingredients are combined.
Finally, pour the rice mixture into a microwave safe (or oven safe) casserole dish. Sprinkle the remaining cheese over the casserole then heat your Easy Mexican Rice in the microwave for 7-9 minutes on high or in the oven for 20 minutes at 350* degrees.
Serve warm and enjoy!
