Rice is one of those foods that many people assume will not freeze well. However, both brown and white rice freeze and reheat beautifully!
How to cook rice for the freezer
Cook rice according to package directions and allow it to cool to room temperature. (Stirring occasionally will allow it to cool more quickly.)
Package the cooled rice in quart-size freezer bags. After filling the freezer bags, remove as much air as possible and seal. Label each bag with a permanent marker. Lay flat in the freezer to freeze.
How to use precooked rice
Precooked rice can be used straight from the freezer. You may need to run hot water over the bag until the solid chunk of rice thaws enough to break up a little.
Transfer rice to a microwave-safe bowl with a lid; add a teaspoon or two of water. Microwave until heated through. Fluff before serving.
