Choose firm potatoes without soft spots or sprouting eyes. Russet and gold potatoesare great choices.
Clean your potatoes thoroughly. Peeling is optional but recommended for a smoothertexture.
Cut potatoes into 1-inch chunks or your desired shape for uniform cooking andfreezing.
Blanch potato pieces in a 4-quart pot of boiling, unsalted water for 3-5 minutes. This step is crucial to halt enzyme activity that causes spoilage.
Immediately transfer the blanched potatoes into a bowl of ice water which will stop the cooking process.
After cooling, drain and pat the potatoes dry with a paper towel in order to remove excess water.
Arrange the potato pieces on a parchment-lined baking sheet, ensuring they're laid out in a single layer.
Transfer the frozen pieces into airtight storage bags. Remove as much air as possible from the bag to prevent freezer burn.
Mark the bags with the date. Frozen potatoes can last up to 3 months for optimal quality.
