Red potatoes-partial cooking, freezing to bake at a later date
They're not going to brown in the freezer. All you have to do is make sure they're not browned before you put them in, and that you cook them reasonably promptly when you take them out.

So if you're shredding a lot, hold them in water til you're ready to cook them. After cooking, rinse to cool them, drain them well and pat them dry before freezing.
