Do you need to blanch potatoes before freezing?

Yes, you should blanch (or partially cook) potatoes before freezing; skipping this step leads to discoloration (turning black/gray) and poor texture (mushy) due to enzymes and ice crystals damaging cell walls, but a quick blanch or parboil inactivates enzymes and helps preserve quality for later use, explains this Facebook post, this NIH article, and this Reddit thread. Blanching (briefly boiling) followed by an ice bath stops enzyme action, keeping color and flavor intact for when you're ready to cook them fully, notes this Facebook post and this YouTube video.

No, blanching is not the same as boiling; blanching uses boiling water but is a specific, short-duration technique that involves a quick plunge into boiling water and then an immediate transfer to an ice bath (shocking) to stop cooking, while boiling is a longer cooking process for full doneness, often without the shock step, focusing on softening or fully cooking food. The key difference is the short time and the ice bath in blanching, which preserves color, texture, and stops enzyme activity, whereas boiling cooks food thoroughly.
