Cook the whole bag, then freeze it
A big bag of potatoes going soft in a warm kitchen. Several conversations cook and freeze them. Plus where to keep the rest, and one line on dry beans.
Built from people with a big cheap bag of potatoes and a warm kitchen — thirty conversations, 445 accounts, 2010 to 2025 — and from the four conversations that cook the bag and freeze it, the one account and three-account caution on where to keep the rest, the four that pair it with beans and lentils, the two corrections on dry beans and the one on butter, the five-conversation argument with rice and beans, and the three conversations, one contraindication and one high caution on B12. The bean line, the fridge split and the green-potato line were checked against US and UK food-safety guidance for this page on 2026-09-04.
The bag was the cheapest thing in the shop and now it is the biggest thing in the kitchen, and the third one from the top has a sprout. The people in these conversations are the source here, and several separate conversations arrived at the same fix.
Cook more of it than you can eat tonight, and freeze the rest.
Mashed or baked are the two they name. Mashed and baked are the two the accounts name. Several conversations do the fast version — a potato in a damp paper towel in the microwave — and one caution says times vary, and the wrong minutes burns it. What has not been cooked goes somewhere cool, dark and dry, and not beside the onions or the bananas: one account gives the detail and a caution backed by several accounts rates it high. The fridge is where the accounts and the world part ways, and the second question below gives both sides by name.
Two lines sit above the rest of this page, and both are the accounts’ own before they are anyone else’s. Dry beans — the thing several conversations put with a potato to make it a meal — carry a toxin that only boiling destroys, and one account who suggested a slow cooker came back to say so. Public food-safety guidance names the kidney bean and says boil hard first. And several conversations, a contraindication and a caution rated high say a potato has no vitamin B12: this page is for stretching a bag through a tight month, not for living on one food, and the last question below says where that ends. If the money that brought you here is the real problem, the support pages on this site are for that part.
Common questions
The bag is huge and they are already going soft. What do I do with it this week?
Cook it, and put what you cooked in the freezer. Several separate conversations say the way to get through a bulk bag is to cook a large batch — mashed or baked are the two they name — and freeze it, so the week becomes reheating instead of peeling. The accounts name mashed and baked as the two that freeze well. Several conversations, short of time, use the microwave: wrap the potato in a damp paper towel or part-cook it first, and it is done far faster than an oven — one caution says microwave times vary and the wrong minutes leaves you with a burnt one. Several conversations use the oven at high heat and roast onions alongside for a cheap second dish. On peeling, one exchange across more than one conversation, evenly split, argues whether the tricks — boiling first so the skin slips off — beat a plain peeler; the accounts’ decider is how many potatoes you are doing and what tools you have. Many separate conversations say the point of a potato is that it takes every method — boiled, mashed, baked, fried, stewed — and one account says a pound a day for more than ten years never got dull. Against that, one account says potatoes are harder to cook well than they look: boiled and mashed can come out bland and frying burns them. One account saves the water from boiled potatoes for bread dough, another fries the peels with spices instead of binning them, and one says cooking, cooling and reheating potatoes turns some of the starch into a form the body digests more slowly — a claim the accounts left as one person’s. How long frozen potatoes keep, and how to keep cooked ones for several days in the fridge, are gaps in these conversations — those are gaps this page leaves too.
Where do I keep the ones I have not cooked yet?
Cool, dark, dry, and not next to the fruit — with one honest split about the fridge. One account gives the detail and a caution backed by several accounts rates it high: potatoes want a cool, dark place — a pantry or a basement, around ten degrees Celsius — and a hot room is too warm for them. Sunlight turns them green and then they rot, one caution says, and another says keep them apart from bananas, onions, apples and avocados, which hurry them along. More than one account raises the honest drawback against instant noodles: a bag of potatoes can sprout and mould within a week or so, and one account says how fast they turn is the real drawback if you have no cool, dry, dark corner. On the fridge, one account and one caution say it is too cold for long-term storage. That is where the world has moved, and the two sides are named: this page’s own line, from outside these conversations: US food-safety guidance still says do not refrigerate raw potatoes, because the cold turns some of the starch to sugar and fried potatoes then form more acrylamide; UK food-safety guidance changed in 2023 after its own research and now says the fridge is fine. So if a warm flat is your only option, the UK guidance is the one that permits the fridge, and the US guidance is the one that would rather you did not fry what came out of it. How to stop sprouting and mould, how long a bag lasts, and what to do when no cool space exists are gaps in these conversations; the external line this page adds is that food-safety guidance says to cut away any green or sprouting parts and to throw out a potato that is very green or bitter.
What do I put with it so it is a meal and not just a potato?
Beans or lentils, an egg, a tin of tomatoes, a little fat — and the corrections about butter and about the skin. Several separate conversations say a potato with beans or lentils is a fuller, cheaper meal than a potato alone, and others add eggs, rice, tinned tomatoes, spices and some fat, alternating them across the week so the plate changes. Several conversations bake at high heat and put butter and sour cream on top for staying power; one caution backed by more than one account says the fancy mashed recipe that went round used so much butter it stopped being cheap, and one correction is blunt that butter and potatoes do not make a complete diet. One account buys dry beans because they cost a fraction of tinned, soaks them overnight and boils them — and that account is the one who corrected themselves on the slow cooker, so read the safety line above. Other one-account additions: a bag of frozen mixed vegetables keeps longer than fresh and mixes into many dishes; stock cubes are cheaper than cartons of stock; a single roast chicken becomes several meals and a soup. More than one conversation names lentils, chickpeas, beans and rice as the other cheap staples that reheat well, with one caution backed by several accounts that plain rice tastes of nothing unless you season it — one account adds rinsing it and measuring the water, and another that the fragrant long-grain kind costs more. On the skin: several separate conversations say leave it on — for convenience, flavour and what they believe is the nutrition — and one account with the numbers answers that the skin’s vitamins and minerals are about the same per gram as the flesh, with a little more fibre; so keep it on because it is easier, not because it is where the goodness hides. Corrections for anyone watching blood sugar or kidney stones: sweet potatoes, despite the name, raise blood sugar more slowly than white ones in one account’s tables, and it is sweet potatoes, not white ones, that carry a lot of oxalic acid.
Are potatoes actually the cheapest thing, or should I be buying rice and beans?
The people here argue this in exchange after exchange and never settle it, so here are the splits and their deciders. In one conversation, an even split: potatoes win on cost, filling power and nutrition, against rice and beans winning on keeping longer, on nutrition and on needing no special storage. In another, a close split, the same way; in a third, also close, the bulk-cooking side against the time-poor side, who say that someone with no time will reach for whatever is quick, noodles included, even if it is worse for them; in a fourth, most of it for lentils and rice; and in a fifth, most of it for lentils on protein. The accounts’ deciders are the same each time: do you have somewhere cool and dark to keep a bag; do you have the time and a hob; and what will you actually eat without grumbling. Several separate conversations say potatoes come out cheaper per calorie than instant noodles, and in the same breath that local prices swing enough to reverse it — one account’s shop had potatoes dearer. More than one conversation defends the noodles: for time-poor working people the quick meal has a place, valued for speed rather than taste, and one account says some of the people eating instant noodles do it because they like them, not because they are broke. Cautions cut the other way: bulk buying needs money up front that you may not have this week, and storing bulk dry goods needs containers. One exchange, evenly split, is worth carrying whole: one says if you are living on potatoes you need real help, not a vegetable tip, and the other says it is still a useful tip — this page holds both, and if the first one is you, the support pages on this site are there for the help part.
Could I just live on potatoes for a while? People say you can.
For a while, some of the people here did — and the same conversations say where it ends. More than one account got through months on potatoes alone, and one lived largely on potatoes, rice and beans for nearly a decade after a spell of homelessness. More than one conversation says a white potato carries all nine essential amino acids and can keep a person going alongside a multivitamin; one exchange, evenly split, argues whether that is survival or a diet, and the accounts’ decider is whether the goal is calories to get through the month or meeting what the guidance says a body needs. Then the limit, from several separate conversations, a contraindication and a caution rated high: potatoes have no vitamin B12, and living on them alone for long enough ends in deficiency and real illness — the accounts name yeast extract, seaweed, eggs, dairy or a supplement as the way B12 gets in, and standard nutrition guidance in the UK and the US says the same about plant foods. One caution says the protein is a little short for keeping muscle over the long run; one says eating only potatoes brings a nausea and an aversion that makes the next one hard to face; one says a lot of butter and salt is not a healthy way to make them bearable, though one account with low blood pressure found the salt helped. One exchange, evenly split, has potatoes and good butter covering every need against the arithmetic of how much butter that would take — the accounts score the arithmetic better evidenced, and so does this page. The long-term health of a potato-heavy diet beyond the vitamin line is a question the accounts raised and left open. If your money has you here, this page is for stretching the bag; the support pages on this site are for the rest.
