The Ultimate Guide to Keep Potatoes Fresh
Potatoes are a pantry staple known for their versatility and long shelf life. However, without proper storage, they can sprout or rot. Understanding how long potatoes last—and the best ways to store them—helps preserve their quality, reduce waste, and keep them ready for all your favorite recipes.
Shelf Life of Potatoes
- At Room Temperature (Pantry):
- Raw, Whole Potatoes: 2-3 months (stored in a cool, dark place)
- New Potatoes (small, thin-skinned): 2-3 weeks
- Sweet Potatoes: 3-5 weeks
- In the Refrigerator:
- Raw Potatoes (not recommended): 2-3 weeks (can affect texture and flavor)
- Cooked Potatoes: 3-5 days (in an airtight container)
- In the Freezer:
- Raw Potatoes (not recommended): Can become grainy when frozen
- Blanched or Cooked Potatoes: 10-12 months
Best Practices for Storing Potatoes
- Store in a Cool, Dark Place – Potatoes last longest when kept in a pantry, cellar, or cupboard at temperatures between 45-55°F (7-13°C). Avoid the fridge.
- Keep Away from Light – Light exposure can cause potatoes to turn green and produce solanine, which can be toxic in large amounts.
- Avoid Storing with Onions – Onions release gases that can cause potatoes to spoil faster.
- Allow for Airflow – Store potatoes in a mesh bag, basket, or paper bag to allow ventilation and prevent moisture buildup.
- Freeze Cooked Potatoes – If you have extra mashed or roasted potatoes, freeze them in airtight containers for long-term use.
Signs Potatoes Are Going Bad
- Soft or Mushy Texture – Indicates rot or excessive moisture.
- Sprouting – Small sprouts are harmless (just cut them off), but heavily sprouted potatoes may taste bitter.
- Green Skin – Caused by light exposure, green potatoes should be peeled or discarded to avoid solanine.
- Mold or Dark Spots – Discard potatoes with visible mold or large black spots.
How to Use Potatoes Before They Spoil
- Mashed Potatoes
- Potato Soups or Stews
- Homemade French Fries or Hash Browns
- Roasted or Baked Potatoes
- Potato Gnocchi or Pancakes
By storing potatoes correctly, you can extend their shelf life and keep them fresh for months. Proper storage ensures you always have this versatile ingredient on hand for quick, delicious meals.
