Q. I have a whole bag of sweet potatoes taking up space in my pantry and I don’t know what to do with them all. I can’t possible eat this many at once! Can you freeze sweet potatoes?
A. Yes, sweet potatoes can be frozen with a little advance preparation. Choose sweet potatoes that are firm and have a deep orange colour for best results. Sweet potatoes should be cooked before freezing for best results. Cut off the ends and peel sweet potatoes. Cut into cubes. Sweet potatoes will change colour when frozen, becoming darker. To prevent or minimize this from happening, dip cubes in a mixture of lemon juice and water, using a ratio of ½ cup lemon juice to a quart of water.
How to freeze sweet potatoes?
Cook sweet potatoes according to desired method (bake, steam, or boil). To freeze cubed sweet potatoes, strain the sweet potatoes then allow to cool on paper towels. Dry the potato cubes, then place the cooled sweet potato cubes on a baking sheet and place in the freezer for about 20 minutes, or until the cubes are hard to the touch. This will help avoid having the cubes stick together during freezing. Place cubes in freezer bags, leaving a little bit of headroom in each bag. Squeeze out excess air and seal. Label and date bags, and store in the coldest part of the freezer. Sweet potatoes can be frozen indefinitely.
To freeze mashed sweet potatoes, puree cooked sweet potato cubes with 2 tablespoons of lemon juice to prevent darkening. It’s recommended to mash sweet potatoes without any additional ingredients. Add extra seasonings after the mixture has been thawed. Scoop pureed sweet potatoes into freezer bags, allowing for a bit of headroom. Smooth bags flat and seal them, removing as much of the air as possible. Label and date freezer bags, and store stacked in the coldest part of the freezer.
To thaw frozen sweet potatoes, remove the freezer bag from the freezer and place in the refrigerator for several hours, until thawed completely. Frozen sweet potatoes can also be thawed by placing the freezer bags under running water. Mashed sweet potatoes should be mixed again to return them to their thicker consistency. Cubed and pureed sweet potatoes can also be added directly from the freezer to recipes that will be cooked through. Previously frozen sweet potatoes should not be refrozen. Thawed sweet potatoes should be eaten within 2-3 days of being thawed.
