Storing cut up potatoes (chips/fries) I have fallen into a slump at the minute where i just don't feel like preparing food when i get home from work, and i would prefer to cut up a larger batch of potatoes in one go and store them in the fridge/freezer in the correct portion sizes, so when i get home i can just throw them into the oven.

The problem i have had with this up to now is, if i put them into the freezer and then try to cook them, the defrosting process turns them to mush. If i put them in the fridge, they have gone off by morning.

Is there a better way to store potatoes that have been cut up?
You can store your cut potatoes in the fridge. Place them in container(s) and cover them completely with plain, unsalted water. They should be fine for at least 2 or 3 days.

I don't know that it's necessary, but I usually drain and rinse them before use.

Alternatively, as you are cooking them in the oven, you could cook a large batch and then store your preferred portion sizes in the fridge or freezer, depending on how long you plan to keep them before use.
