I asked the same question, my hand hovering over the freezer door like I was defusing a bomb. Spoiler alert: Yes, but only if you do it right. Raw potatoes turn into watery, gray-tasting ghosts if you just toss them in. The trick is to blanch them first—a quick boil that stops the enzymes from wrecking your future roasties. Think of it as giving your potatoes a spa day before they hit the deep freeze.
The Science Bit (Made Fun, I Promise)
Potatoes are about 80% water. When you freeze them raw, those water crystals explode the cell walls. You end up with mush. Not the crispy, golden goal. Blanching for 3–4 minutes partially cooks the starch, locking in texture. Then you shock them in ice water to stop the cooking. It sounds fancy, but it’s literally just boiling and dumping.
