Don’t fridge potatoes. But do fridge sweet potatoes? Actually, don’t fridge those either. They get hard and woody inside.
Storing potatoes: how & where - Plantura
What about cooked potatoes? Yes, fridge those immediately. They’re safe for 3–4 days. Cold is great after they’ve been boiled or roasted.
And french fries? Keep them in the freezer, not the fridge. That’s a whole other story.
The Bottom Line
Your fridge is a villain in the potato world. It ruins flavor, causes sprouts, and turns them bitter. But it’s not evil—it’s just misunderstood.
If you must use the fridge (tiny apartment, no pantry), keep them in the crisper drawer. Wrap them in a paper towel to absorb moisture.
Then eat them within a week. And never, ever fry them. Boil or mash them instead—the sugar won’t ruin those dishes as much.
