How to Store Potatoes: The Basic Setup
Choose a location that is cool, dark, dry, and ventilated. A pantry, cellar, or cupboard away from appliances can work if it does not become warm or damp. Light can cause potatoes to develop green areas, while moisture encourages decay.
Keep potatoes in a breathable paper bag, mesh bag, basket, or cardboard box with ventilation. Do not seal them in an airtight plastic container because trapped moisture can speed spoilage. Leave enough space for air to move around the potatoes and avoid stacking them under heavy items.
- Keep potatoes out of direct sunlight.
- Keep them away from sinks, steam, and heat-producing appliances.
- Store only dry, intact potatoes in the main storage area.
Sort and Prepare Potatoes Before Storage
Inspect potatoes when you bring them home and separate any that are wet, leaking, moldy, or badly damaged. One deteriorating potato can spread moisture and decay to nearby potatoes. Do not wash whole potatoes until you are ready to prepare them, because extra surface moisture can shorten storage life.
Handle potatoes gently to avoid bruises and cuts. Keep them in a single loose layer when practical, or use a container that lets you check the lower potatoes easily. Review the batch at least weekly and remove anything that has clearly spoiled.
Should Potatoes Go in the Refrigerator?
For best everyday quality, whole potatoes are generally kept in a cool, dark, dry pantry or similar location rather than the refrigerator. Cold storage can change the potato's texture and cooking performance, especially when potatoes are later fried or roasted. Follow package directions for specialty or prepared potato products.
Peeled or cut potatoes are different from whole potatoes because cutting exposes moist surfaces to contamination and quality loss. Refrigerate cut potatoes promptly in a clean, covered container, following FDA guidance for cut produce. Keep refrigerator temperature at 40 degrees Fahrenheit or below, as recommended by FoodSafety.gov.
- Whole and unwashed: cool, dark, dry, ventilated storage.
- Peeled or cut: covered and refrigerated promptly.
- Cooked: refrigerate leftovers promptly and use the USDA FoodKeeper guidance.
Storing Cooked, Peeled, and Cut Potatoes
Place cooked potatoes and potato dishes in shallow, covered containers so they cool promptly in the refrigerator. Refrigerate perishable leftovers within two hours, or within one hour when the surrounding temperature is above 90 degrees Fahrenheit. Label the container with the preparation date so it is easy to use older food first.
Use the USDA FoodKeeper tool for the current recommended storage period for a particular cooked potato dish. Reheat leftovers thoroughly, and discard food that has an unusual odor, appearance, or texture. Do not taste questionable food to decide whether it is safe.
Sprouts, Green Areas, and Spoilage
Sprouting usually signals that a potato is aging and may have declining quality. Small sprouts can be removed along with the surrounding area if the potato is otherwise firm and sound, but a soft, shriveled, moldy, leaking, or strongly bitter potato should be discarded. Avoid eating potatoes with extensive green discoloration or other signs that make their condition uncertain.
Do not rely on a storage date alone to judge a whole potato. Check firmness, moisture, visible mold, damage, and odor each time you prepare one. When in doubt about a questionable potato or dish, follow official food-safety guidance and discard it.
A Simple Potato Rotation Routine
Buy an amount you can use before the potatoes begin to deteriorate, especially if your storage area is warm. Put newer potatoes behind older ones so the oldest usable potatoes are selected first. Keep a small open space around the container so you can inspect the batch without unpacking the whole area.
Once a week, remove damaged potatoes, wipe moisture from the storage container, and check the surrounding area for heat or condensation. Plan a meal around potatoes that are still firm but need to be used soon. Compost or dispose of spoiled potatoes according to your local waste program rather than using them in cooking.

Questions that need a little more context
Can I store potatoes in a plastic bag?
A sealed plastic bag can trap moisture, which may encourage decay. Transfer whole potatoes to a breathable bag, basket, or ventilated container, and keep them away from light and heat.
Should potatoes be stored with onions?
Keep potatoes and onions in separate containers. Both need ventilation, and storing them together can increase exposure to moisture and spoilage gases.
Can I refrigerate whole potatoes?
Whole potatoes are generally better kept in a cool, dark, dry, ventilated pantry for everyday quality. Refrigeration can affect their texture and cooking behavior, so refrigerate cut or cooked potatoes instead.
How should I store leftover mashed or baked potatoes?
Place leftovers in a shallow, covered container and refrigerate them promptly. Use the USDA FoodKeeper tool for the recommended storage period for the specific dish, and discard leftovers that look or smell questionable.
What should I do with a green or badly spoiled potato?
Do not use a potato with extensive green discoloration, mold, leaking, severe softness, or a strong bitter odor or taste. When the condition is uncertain, discard it rather than trying to salvage it.
