How To Freeze Mashed Potatoes
There are two ways to freeze mashed potatoes, depending on whether you want to freeze as single serves or a big batch. Here’s what you need to do:
Method 1: Single serving
- Cool down mashed potatoes completely and scoop them into individual servings on a baking tray lined with parchment paper.
- Stick the tray into the freezer for an hour or two (scoops freeze really fast!).
- Once it’s completely frozen, transfer to a ziplock bag and seal it, taking out as much air as possible.
- Put this bag of frozen mashed potato scoops back into the freezer, label, and use up within 2 months.
I use this method when I am storing leftovers as the quantity is smaller. I only take out as many as I need, and put the rest back in. So handy!
Method 2: Large batch in freezer bags
- Once the mashed potatoes have completely cooled, grab a ziplock bag and fill it about 3/4th of the way. Seal the bag, leaving a small opening to allow air to pass.
- Place the bag on your countertop and gently spread out the mashed potatoes into a flat, even layer. Make sure to remove any visible air pockets before sealing all the way.
- Repeat the process for the rest of the mashed potatoes.
- Lay the bags of flattened mashed potato on a tray or parchment paper and freeze for a few hours.
- Once frozen, take out the frozen sheets of mashed potatoes and transfer to a glass container or bigger zip lock bag to save freezer space.
This method works really well, but personally I find it time consuming. So this next one is my preferred method to freeze a large batch of mashed potatoes.
Method 3: Large batch in a container with lid
- Transfer room temperature mashed potatoes to an airtight container. Flatten out the top using the back of a spoon or spatula.
- Wrap the entire container in cling film three times, and then put the lid on. This is an essential step to prevent freezer burns and odors.
- Put it into the freezer and forget about it until you are ready to eat.
This is a great freezing method when you plan to use up the whole batch in one go – like for a party or gathering. This is also the method my preferred method to freeze mashed potatoes in large batches. I love quick and hassle-free it is.
How to Reheat Frozen Mashed Potatoes
It’s very easy to reheat frozen mashed potatoes without causing any breakdown in its texture or flavor. The best way to do so is to first allow frozen mashed potatoes to thaw out completely in the fridge. This can take anywhere between 1-2 days depending on the quantity. Once the mashed potatoes have completely thawed, reheat them using one of the following methods:
- Stovetop: Transfer the thawed mashed potatoes into a saucepan and reheat over a double boiler, stirring occasionally until heated through.
- Microwave: Reheat thawed mashed potatoes in a covered microwave safe bowl for about 3 minutes, stirring occasionally until heated through. Depending on the power of your microwave, the timing may differ.
- Oven: Transfer thawed mashed potatoes into an oven-safe dish and cover it up with aluminum foil. Bake in a preheated oven for about 20-30 minutes until heated through.
- Slow cooker: Transfer thawed mashed potatoes to a slow cooker on low setting and reheat for 2-4 hours, stirring occasionally.
