How to Store Potatoes the Right Way
The best way to store potatoes is in a cool, dark, dry, and well-ventilated place like a pantry or cellar. Keep them in a paper or mesh bag, not plastic. Never store them in the refrigerator, as this will ruin their taste and texture. Stored correctly, potatoes can last for months.
Potatoes are a pantry all-star—versatile, affordable, and delicious. But they have a few enemies: light, heat, and moisture. Storing them incorrectly can lead to a disappointing bag of sprouted, green, or mushy spuds. And the most common mistake? Putting them in the refrigerator.
Learning **how to store potatoes** correctly is the secret to making them last not just for weeks, but for months. This write-up will cover the simple science behind why potatoes spoil, the ideal conditions for long-term storage, and what to do if your potatoes start to sprout or turn green. Let’s dig in and keep those spuds perfect.
The Science of Spoilage: Sprouting, Greening, and the Fridge Problem
To store potatoes perfectly, you need to understand their three main vulnerabilities.
1. Sprouting (The Problem with Warmth)
Potatoes are living tubers, and their natural goal is to grow into a new plant. Warmth and light act as a signal for them to wake up from dormancy and start sprouting. While a potato with small sprouts is still safe to eat (just remove the sprouts), it’s a sign that the potato is converting its starches into sugars to fuel the new growth, which can affect its texture.
2. Greening (The Problem with Light)
When potatoes are exposed to light, they produce chlorophyll, which turns their skin green. This isn’t the main problem. The real issue is that light also triggers the production of a bitter-tasting, toxic compound called **solanine**. While you’d have to eat a lot of green potatoes to get seriously ill, it’s best to avoid it. The FDA advises cutting away any green parts of the potato before cooking and discarding any that are heavily greened.
3. Sweetness (The Problem with the Fridge)
The cold temperature of the refrigerator causes a potato’s starches to convert into sugars. This results in an unpleasantly sweet flavor and a waxy, discolored texture when cooked. Furthermore, these higher sugar levels can lead to increased levels of a chemical called acrylamide when the potatoes are fried, roasted, or baked at high temperatures, a concern highlighted by food safety agencies like the CDC.

Where you store your potatoes has a massive impact on how long they last. This chart shows what you can expect from each environment.
The Ideal Storage Environment for Potatoes
The perfect home for a potato mimics the conditions of an old-fashioned root cellar. You’re aiming for four things: **cool, dark, dry, and well-ventilated.**
- Find a Cool, Dark Spot: The ideal temperature is between 45-55°F (7-13°C). For most people, this means the coolest, darkest corner of a pantry, a basement, or even a garage.
- Provide Good Airflow: Potatoes need to breathe to prevent moisture buildup, which leads to rot. Never store them in a sealed plastic bag. Instead, keep them in the mesh or paper bag they came in, or transfer them to a burlap sack, a cardboard box with holes, or a wire basket.
- Keep Them Away from Onions: This is a classic mistake! Onions release ethylene gas, which will cause your potatoes to sprout prematurely. Store them in separate areas. This is a key tip we emphasize in our broader look at vegetable storage.

How to Freeze Potatoes (The Right Way)
While you can’t freeze a raw potato, you can absolutely freeze them after a quick pre-cooking step called blanching. This is the best answer for **how to store potatoes long term** if you don’t have a cool pantry.
The Blanching and Freezing Process
- Prep the Potatoes: Wash, peel, and cut your potatoes into your desired shape (cubes for hash browns, sticks for fries, etc.).
- Blanch Them: Drop the cut potatoes into a pot of boiling water for 3-5 minutes, depending on the size of the pieces. This step deactivates the enzymes that cause discoloration and texture loss.
- Shock in Ice Water: Immediately transfer the blanched potatoes to a large bowl of ice water. This stops the cooking process instantly.
- Dry and Flash Freeze: Drain the potatoes and pat them completely dry. Spread them in a single layer on a baking sheet and freeze until solid (about 1-2 hours).
- Package and Store: Transfer the frozen potatoes to a freezer bag or airtight container. They will last for 8-12 months. This method is a food preservation staple, endorsed by authorities like the National Center for Home Food Preservation.
Your Potato Storage Questions, Answered
What is the best way to store potatoes?
The best way to store potatoes is in a cool, dark, and well-ventilated place, such as a pantry, cellar, or a dark corner of your kitchen. Keep them in a paper bag, cardboard box, or mesh bag. Do not store them in the refrigerator.
How do you keep potatoes from sprouting?
To keep potatoes from sprouting, store them in a cool, dark place. Light and warmth are the main triggers for sprouting. Also, keep them away from onions, as the gases they release can accelerate sprouting.
Why shouldn’t you store potatoes in the fridge?
Storing potatoes in the fridge causes their starch to convert into sugar. This gives them an unpleasantly sweet taste and a gritty texture when cooked. It can also cause them to form higher levels of acrylamide when fried or roasted.
How long can you store potatoes?
When stored under ideal cool, dark conditions, raw potatoes can last for several months. At a typical room temperature, they will last for 1 to 2 weeks.
Is it safe to eat potatoes that have sprouted or turned green?
You can eat potatoes that have small sprouts by simply removing the sprouts. However, the green skin contains a toxin called solanine. You should peel away all green parts before cooking. If a potato is very green or shriveled, it’s best to discard it.

Our Process & Sources
This information was compiled using best practices from agricultural experts and food safety recommendations from organizations like the FDA to provide the most reliable advice for your kitchen.
Potatoes last 3 to 5 weeks in a cool, dark pantry at 45 to 55°F and should never go in the fridge because cold converts their starch to sugar, changing the taste. Sweet potatoes look similar but need even warmer storage conditions, ideally above 55°F, and last 3 to 5 weeks in the same pantry spot. Garlic is a classic pantry companion to potatoes but should never be stored in the same bag because the moisture garlic releases causes potatoes to sprout faster. Root vegetables like beets are the opposite and prefer the fridge, lasting up to 3 weeks in the crisper.
