Yes, you can freeze sweet potatoes but unfortunately not without partially cooking them first. You can freeze them sliced, diced, or mashed. This rule goes for any potato really.
Due to sweet potatoes and other potatoes having a high water content freezing them without cooking them first doesn’t work out well. They tend to get watery and mushy and freezer burnt.
Cooking them and then freezing them allows for you to have fresh sweet potatoes, even in the off-season, in the freezer for up to 12 months.
Freezing sweet potatoes allows for you to have hashbrowns, mashed potatoes, french-fries and many more things at your fingertips in or out of season.
So depending on how you want to freeze your sweet potatoes will dictate how you go about freezing them.
How to freeze sweet potatoes
There are a few different ways to go about freezing your sweet potatoes and it all depends on how you plan to use them later.
It is important to only freeze sweet potatoes that are fresh. Don’t wait until they are going bad and then freeze them.
I will go over how to freeze sweet potatoes that are cubed, fries, wedges, and mashed.
You always want to start off by washing your sweet potatoes. This goes for any method you are using to freeze them.
Run them under cold water giving them a little scrub using your hands or a spud brush. This is to get off any dirt or bacteria that might be on them from the farm or travel to the stores.
Peeling them is optional but it is something I always do. I find that not peeling the skin off when I freeze them makes for chewy skin later. But this is your call.
1. Freezing cubed or wedged sweet potatoes
You want to cube your potato into bite-size pieces about 1-2 inches. As with any cooking you want to be sure that the sizes are consistent to ensure that your potatoes cook evenly.
Blanch the cubed or wedged sweet potatoes. This will help you to achieve crispier potatoes when you are ready to use them out of the freezer.
Blanching means placing them in a pot of boiling water until they are tender but not fully cooked. The time will vary depending on the size and quantity you have in the pot.
You want them to be tender enough to just barely be able to poke them with a fork but not easily. As I said, it’s important that you don’t fully cook them.
Once they are tender, drain them from the hot water and put them directly into an ice bath to stop the cooking process.
Give them a minute in the ice water and then drain them again, let them completely cool and pat them dry with a paper towel.
Line a baking sheet with parchment paper and spread the potatoes out in a single layer on a baking sheet. Place them in the freezer for 4-5 hours or until they are completely frozen solid.
Remove them from the baking sheet and put them into a freezer bag. Be sure to remove as much air as you can and seal the bag closed.
Place them in your freezer bag laying them down trying to keep them in somewhat of a single layer. This will help keep them from sticking together and make it easier to take them out of the bag later.
How to reheat frozen sweet potato cubes/wedges
To reheat cubes or wedges just simply stick them into the oven from the freezer and bake at 350 degrees for 15-20 minutes.
2. How to freeze sweet potato fries
The same thing applies to sweet potato fries as with the cubed or wedged potatoes. You want to blanch them before you freeze them. Remember this has the added benefit of making crispier fries!
Cut up your fries as thin or as thick as you would like them and then add them into a pot of boiling water to blanch them for about 2-3 minutes. Don’t forget, you do not want to fully cook them.
After 2-3 minutes drain the water and put them into an ice bath. This will stop the cooking process. Drain them from the ice bath, pat them dry, and allow for them to fully cool off.
Once they are completely cooled off, place them on a baking sheet lined with parchment paper in a single layer and put them into the freezer for about 2 hours.
Once they are frozen put them into a freezer bag and keep them in the freezer until you need them. They should last in the freezer for up to 12 months.
How to reheat frozen sweet potato fries
These bake really nicely right from them the freezer into the oven or fryer. Simply place them on a baking sheet and place them in the oven for 20-30 minutes at 350 degrees.
Or if you are going to fry them, heat up your oil and add them into the hot oil for about 4-5 minutes or until the crispy.
3. How to freeze mashed sweet potatoes
Freezing mash potatoes is a little different than fries or wedges. You want to go ahead and make your sweet potatoes as if you were going to serve them.
Peel and cube them before them to a pot of boiling water. Once they are ready to be mashed add in your seasonings, cream or whatever it is that you like to add into your mashed sweet potatoes.
Allow for them cool off completely. Two great ways to store them are to either put them into a freezer bag and then lay the bag flat and freeze them.
Or, I like to freeze them into icecube trays so that I can easily take out how much or as little is needed and they thaw out nicely too. I would recommend about 4 cubes for one side.
How to reheat frozen mashed potatoes
Just take them out and reheat them in a pan until they are back to the consistency of mashed potatoes. It’s super fast and great to have on hand year-round.
