Yes. Just make sure to put it in a freezer safe container. When thawing, I place the sealed container in a sink with hot water for about 10 minutes so that it will come out of the container. Transfer it into a pot and heat it over the stove on medium-high heat for about 15 minutes. Stir frequently so that it doesn't get scorched on the bottom. Just a side note, reheating it on the stove can potentially change the consistency if there were chunks of potatoes. Stirring it can break the chunks and result in an inconsistent texture. I don't find this to be a problem though. It's just as delicious and super simple.
