Allow your cooked batch of rice and beans to cool and come to room temperature. You can even lay the dish onto a baking tray making sure that it’s in an even layer. It will take about 30 minutes for the dish to cool down completely.

Alternatively, you can cool the rice and beans in your fridge to speed up the cooling process.

Divide the cooled rice and beans into 1 or 2 cup portions, depending on how much of the prepared dish is left. This will ensure that the dish remains free of freezer burn. Moreover, this will allow you to reheat the exact amount of rice and beans whenever you want to eat it.  

Put the divided portions of rice into airtight freezer bags such as Ziploc bags or vacuum sealer bags. Once all the rice and beans are in the bag, flatten the bag out to create a thin, even layer.

Label each bag with the contents and the amount inside. Also, add the date of storage to the label. This way, when you take out the rice and beans to reheat them, it will help you determine how long the dish has been in your freezer and how many servings you have. 

Put the bags of rice and beans in your freezer.
