How To Freeze Sweet Potatoes

There are a few methods you can choose to freeze sweet potatoes so let’s start with freezing raw sweet potatoes for those times when you have excess potatoes and no need for them right now. So let’s get started:

  1. Clean
    Freezing sweet potatoes raw does take a little work as they won’t hold their texture and taste if you don’t blanch them first so step one is to scrub and make sure your potatoes are free from dirt.
  2. Chop
    Next, chop your potatoes into chunks about the size you want. You’ll want to consider how you normally use your sweet potatoes. If you tend to cook wedges, then cut them into wedges for example.
  3. Prepare for Blanching
    Next, you need to prepare everything required to blanch the potatoes. So, you need to boil some water in a pan and prepare a bowl of ice water. You need to keep the ice water by the cooker as you will need to have it to hand.
  4. Blanch
    When the water is boiling pop the potatoes into a metal colander and lower it into the boiling water. Let the potatoes boil for a couple of minutes and then take them back out again and immediately plunge the colander and potatoes into the ice water.
  5. Drain and Dry
    Drain and allow the potatoes to dry. You can help them along by patting them with kitchen paper or a clean towel.
  6. Freeze
    You can either flash freeze your potatoes to avoid them sticking together and then store in a large bag or you can freeze them immediately in portions in individual freezer bags. Place the bag(s) into the freezer.
