How to Store Potatoes - Should You Refrigerate

Potatoes are one of the world's most versatile vegetables — and one of the most commonly stored incorrectly. Should you refrigerate potatoes? The short answer is no — but there's more to it. Here's the complete guide to storing potatoes properly.

Should You Refrigerate Potatoes?

No — do not refrigerate raw potatoes. Cold temperatures convert the starch in potatoes to sugar, which causes them to taste overly sweet and turn an unpleasant dark color when cooked (a process called cold-induced sweetening). Refrigeration also causes the texture to become gritty. The ideal storage temperature for potatoes is 45–55°F (7–13°C) — cooler than room temperature but warmer than a refrigerator.

How to Store Potatoes at Room Temperature

1. Store in a cool, dark, dry, well-ventilated spot — A pantry, cellar, or cupboard away from light and heat is ideal. Light causes potatoes to turn green and produce solanine, a mildly toxic compound.
2. Use a paper bag, mesh bag, or open basket — Potatoes need airflow. Never store in a sealed plastic bag — trapped moisture causes rot and mold.
3. Keep away from onions — Onions emit ethylene gas and moisture that cause potatoes to sprout faster. Store in separate locations.
4. Don't wash before storing — Wash only right before cooking.

When Is It Okay to Refrigerate Potatoes?

• Cooked potatoes — Always refrigerate cooked potatoes. Store in a ComSaf Airtight Container and use within 3–5 days.
• Cut raw potatoes — If you've cut potatoes and can't cook them immediately, submerge in cold water in a sealed container and refrigerate. Use within 24 hours. The water prevents browning.

How Long Do Potatoes Last?

• Whole potatoes (cool, dark pantry): 2–3 months
• Whole potatoes (room temperature counter): 1–2 weeks
• Cut raw potatoes (submerged in water, fridge): up to 24 hours
• Cooked potatoes (airtight container, fridge): 3–5 days
• Frozen (cooked): up to 12 months

How to Freeze Potatoes

Raw potatoes don't freeze well — they become watery and grainy. Instead, cook first: blanch cubed potatoes for 3–5 minutes, or fully cook and mash. Cool completely, then store in a SPLF Reusable Freezer Bag. Lasts up to 12 months.

Signs Potatoes Have Gone Bad

• Green skin or flesh (cut away generously — contains solanine)
• Soft, shriveled, or mushy texture throughout
• Mold on the skin
• Foul or earthy-sour smell
• Excessive sprouting (small sprouts are fine to remove — large ones indicate significant quality loss)

Quick Tips Summary

• ✅ Store in a cool, dark, dry, ventilated spot — pantry or cellar is ideal
• ✅ Use a paper bag, mesh bag, or open basket
• ✅ Keep away from onions and light
• ✅ Refrigerate cooked potatoes in an airtight container for 3–5 days
• ❌ Don't refrigerate raw whole potatoes — causes sweetening and gritty texture
• ❌ Don't store near onions — causes faster sprouting
