The fridge is the enemy. The countertop, however, is your best friend—for the short term. A bowl of potatoes on the kitchen counter looks rustic and lovely, but they’ll sprout within a week if the room gets warm. That’s why your grandmother kept hers in a paper bag in the cellar.
Here’s a fun fact: The average Irish household in the 19th century stored potatoes in a “potato pit” dug into the earth. They didn’t have fridges, but they understood dark, cool, and humid. You can replicate this with a cardboard box in the coolest corner of your pantry.
But what about sweet potatoes? They get their own separate chapter. Sweet potatoes are even more sensitive to cold—they’ll turn hard and develop a weird, bitter core immediately in the fridge. Keep them cozy at room temp, away from onions.
When the Fridge Might Save You
There is one exception: cooked potatoes. Leftover mashed, boiled, or roasted potatoes? Yes, fridge them immediately. Cooked spuds are a different species—they’re moisture-laden and prone to bacteria. Pop them in an airtight container, and they’ll last up to five days.

Another exception: If you live in a tropical climate with no air conditioning, the fridge is the lesser of two evils. Heat and humidity turn potatoes into sprouting science experiments. In that case, cool them down by storing them in the crisper drawer, and use them within two weeks.
And here’s a pro tip: Never store potatoes with apples or onions. Apples release ethylene gas that makes potatoes sprout faster. Onions? They’ll both spoil in a symphony of mush. Give them their own bunk beds.
