How much Mexican rice for 20 people?

To serve 20 people, you generally need about 1/4 to 1/3 cup of uncooked Mexican rice per person, which translates to approximately 5 to 7 cups of uncooked rice in total. This amount will yield around 10 to 14 cups of cooked rice, depending on the cooking method. It's always a good idea to prepare a little extra to accommodate varying appetites.
