How to Store Potatoes

Potatoes are a versatile and nutritious vegetable that can be enjoyed in many ways. Whether you like them baked, boiled, roasted, fried, or mashed, potatoes are a staple in many cuisines and diets. However, potatoes can also spoil quickly if not stored properly, leading to waste and loss of quality.

In this article, we will show you how to store potatoes so they can last longer and retain their freshness and flavor. We will also cover the best practices for selecting, preparing, and preserving potatoes.

Why Proper Potato Storage Matters

Potatoes are tubers that grow underground and store energy in the form of starch. When harvested, potatoes are still alive and undergo various physiological changes that affect their quality and shelf life. Some of these changes include sprouting, greening, sweetening, and softening. These changes can make potatoes less appealing, less nutritious, and even toxic in some cases.

Proper potato storage can help prevent or delay these undesirable changes and extend the shelf life of potatoes. By storing potatoes in optimal conditions, you can also preserve their vitamin C content, which is important for immune health and wound healing.

Additionally, proper potato storage can help reduce food waste and save money by avoiding spoilage and discarding of potatoes.

Key Factors Affecting Potato Storage

How to Store Potatoes

There are several factors that affect how long potatoes will last and how well they will maintain their quality. These factors include temperature, light, humidity, ventilation, and ethylene gas. Here is how each factor influences potato storage and what you can do to optimize it.

1. Temperature: Potatoes should be stored in a cool place, but not too cold. The ideal temperature range for potato storage is between 43–50°F (6–10°C). This temperature slows down the rate of sprouting and preserves the vitamin C content of potatoes. Storing potatoes at room temperature or above can accelerate sprouting and cause vitamin C loss. Storing potatoes in the refrigerator or freezer can also harm their quality, as the cold temperature converts the starch into sugar, making potatoes sweeter and altering their texture and color.

2. Light: Potatoes should be stored in a dark place, away from sunlight or artificial light. Exposure to light can cause potatoes to produce chlorophyll, which turns their skin green. While chlorophyll itself is harmless, it also indicates the presence of solanine, a toxic chemical that can cause nausea, vomiting, and diarrhea in high doses. Solanine is mostly concentrated in the peel and the underlying green flesh, so it can be removed by peeling or cutting off the affected parts. However, it is better to prevent greening by storing potatoes in a dark place.

3. Humidity: Potatoes should be stored in a humid place, but not too wet. The ideal humidity level for potato storage is between 80–90%. This humidity prevents potatoes from losing moisture and becoming shriveled or soft. However, too much moisture can promote mold growth and rotting, so potatoes should not be washed or soaked before storage. Potatoes should also be kept dry and free of condensation during storage.

4. Ventilation: Potatoes should be stored in a well-ventilated place, with enough air circulation to prevent heat buildup and gas accumulation. Potatoes should be stored in a cardboard box, paper bag, mesh bag, or basket that allows air to flow through. Plastic bags or containers should be avoided, as they trap moisture and reduce ventilation. Potatoes should also be stored in a single layer or loosely packed, with some space between them to allow air movement.

5. Ethylene gas: Potatoes should be stored away from other fruits and vegetables that produce ethylene gas, such as apples, bananas, onions, and tomatoes. Ethylene gas is a plant hormone that triggers ripening and senescence in fruits and vegetables. Exposure to ethylene gas can cause potatoes to sprout faster and lose their quality. Therefore, potatoes should be stored separately from other produce or in a different room or cabinet.

Best Option For Storing Your Potatoes

How to Store Potatoes

In the previous article, we discussed the general factors that affect potato storage and how to optimize them. In this article, we will explore some specific storage scenarios and their advantages and disadvantages. Depending on your available space, budget, and storage needs, you can choose the best option for storing your potatoes.

1. Pantry or Cabinet

One of the most common and convenient places to store potatoes is in a pantry or cabinet. This is suitable for short-term storage, as it is easy to access and does not require any special equipment or preparation. However, there are some drawbacks to this option, such as:

i. Temperature: Most pantries or cabinets are located in the kitchen, which can be warmer than other parts of the house. This can cause potatoes to sprout faster and lose their quality. To avoid this, you should store potatoes in the coolest part of your pantry or cabinet, away from heat sources and direct sunlight.

ii. Light: Pantries or cabinets may not be completely dark, especially if they have windows or lights. This can cause potatoes to turn green and produce solanine, a toxic chemical. To avoid this, you should store potatoes in a cardboard box, paper bag, or basket that blocks out light. You can also cover them with a cloth or newspaper.

iii. Humidity: Pantries or cabinets may not have the ideal humidity level for potato storage, which is between 80–90%. This can cause potatoes to lose moisture and become shriveled or soft. To avoid this, you should store potatoes in a cardboard box, paper bag, or basket that allows some moisture to escape. You can also place some newspaper or straw at the bottom of the container to absorb excess moisture.

iv. Ventilation: Pantries or cabinets may not have enough ventilation for potato storage, as they are enclosed spaces that can trap heat and gas. This can promote mold growth and rotting, as well as trigger ripening and senescence in other fruits and vegetables. To avoid this, you should store potatoes in a cardboard box, paper bag, mesh bag, or basket that allows air to flow through. You should also store potatoes separately from other produce or in a different room or cabinet.

2. Basement or Root Cellar

One of the best places to store potatoes is in a basement or root cellar. This is ideal for long-term storage, as it provides the optimal conditions for potato storage. A basement or root cellar is usually cool, dark, humid, and well-ventilated, which can extend the shelf life of potatoes and preserve their freshness and flavor. However, there are some challenges to this option, such as:

i. Availability: Not everyone has a basement or root cellar in their house, or enough space to store potatoes. If you do not have such a place, you may need to build one or rent one from someone else. This can be costly and time-consuming, and may not be feasible for everyone.

ii. Accessibility: A basement or root cellar may not be easily accessible, especially if it is located far from the kitchen or outside the house. This can make it inconvenient to check on your potatoes regularly and remove any spoiled ones. It can also make it harder to use your potatoes when you need them, as you may have to go downstairs or outside to get them.

iii. Maintenance: A basement or root cellar may require some maintenance to keep it in good condition for potato storage. You may need to monitor the temperature, light, humidity, and ventilation levels and adjust them as needed. You may also need to clean the place and remove any pests or rodents that may damage your potatoes.

3. Garage

Another possible place to store potatoes is in a garage. This can be a good option if you have enough space and protection from light and temperature fluctuations. However, there are some risks to this option, such as:

i. Temperature: A garage can be subject to extreme temperature changes, depending on the season and the weather. This can cause potatoes to freeze or overheat, which can damage their quality and shelf life. To avoid this, you should store potatoes in a insulated container or box that can regulate the temperature. You should also avoid placing potatoes near the garage door or windows, where they can be exposed to direct sunlight or cold air.

ii. Light: A garage can be exposed to light, especially if it has windows or doors that are not covered. This can cause potatoes to turn green and produce solanine, a toxic chemical. To avoid this, you should store potatoes in a cardboard box, paper bag, or basket that blocks out light. You can also cover them with a cloth or newspaper.

iii. Humidity: A garage may not have the ideal humidity level for potato storage, which is between 80–90%. This can cause potatoes to lose moisture and become shriveled or soft. To avoid this, you should store potatoes in a cardboard box, paper bag, or basket that allows some moisture to escape. You can also place some newspaper or straw at the bottom of the container to absorb excess moisture.

iv. Ventilation: A garage may not have enough ventilation for potato storage, as it is an enclosed space that can trap heat and gas. This can promote mold growth and rotting, as well as trigger ripening and senescence in other fruits and vegetables. To avoid this, you should store potatoes in a cardboard box, paper bag, mesh bag, or basket that allows air to flow through. You should also store potatoes separately from other produce or in a different room or cabinet.

Potatoes are a delicious and nutritious vegetable that can be enjoyed in many ways. However, potatoes can also spoil quickly if not stored properly, resulting in waste and loss of quality. By choosing the best option for storing your potatoes, you can extend their shelf life and preserve their freshness and flavor. Remember to store potatoes in a cool, dark, humid, and well-ventilated place, and check them regularly for signs of spoilage.

How to Store Potatoes

Potatoes are a delicious and nutritious vegetable that can be enjoyed in many ways. However, potatoes can also spoil quickly if not stored properly, resulting in waste and loss of quality.

Therefore, it is important to know how to store potatoes in optimal conditions that can extend their shelf life and preserve their freshness and flavor.

In this section, we will show you the steps for storing potatoes, from choosing a suitable storage location to sorting and inspecting potatoes for any damage or spoilage.

1. Choose a Suitable Storage Location

The first step for storing potatoes is to choose a suitable storage location. The ideal storage location for potatoes is a cool, dark, humid, and well-ventilated place, such as a basement, cellar, garage, or pantry.

The optimal temperature range for potato storage is between 43–50°F (6–10°C). The optimal humidity level for potato storage is between 80–90%. The optimal light level for potato storage is zero or minimal. The optimal ventilation level for potato storage is moderate to high.

These conditions can help prevent or delay the undesirable changes that affect potato quality and shelf life, such as sprouting, greening, sweetening, and softening. These changes can make potatoes less appealing, less nutritious, and even toxic in some cases.

By choosing a suitable storage location, you can also preserve the vitamin C content of potatoes, which is important for immune health and wound healing.

2, Sort and Inspect Potatoes for Any Damage or Spoilage

The second step for storing potatoes is to sort and inspect potatoes for any damage or spoilage. Before storing potatoes, you should remove any dirt or debris from them, but do not wash or soak them, as this can introduce moisture and promote mold growth and rotting.

You should also sort potatoes by size and variety, as different types of potatoes may have different storage requirements and shelf lives.

You should also inspect potatoes for any signs of damage or spoilage, such as cuts, bruises, cracks, sprouts, green spots, mold, rot, or insects.

Damaged or spoiled potatoes can affect the quality and shelf life of the rest of the potatoes, as they can release ethylene gas, which can trigger ripening and senescence in other fruits and vegetables.

They can also spread diseases and infections to other potatoes, such as bacterial soft rot, fusarium dry rot, or potato blight.

Therefore, you should discard any damaged or spoiled potatoes, or use them as soon as possible. You can also peel or cut off the affected parts of the potatoes, if they are not too severe. However, it is better to prevent damage or spoilage by choosing healthy and fresh potatoes in the first place, and handling them gently and carefully during transportation and storage.

3. Place Potatoes in Breathable Containers

The third step for storing potatoes is to place potatoes in breathable containers, such as paper bags, mesh baskets, cardboard boxes, or wooden crates.

These containers can allow air to circulate around the potatoes, which can prevent heat buildup and gas accumulation, and regulate the temperature and humidity levels. They can also block out light, which can prevent greening and solanine production.

You should avoid storing potatoes in plastic bags or containers, as they can trap moisture and reduce ventilation, which can promote mold growth and rotting. You should also avoid storing potatoes in metal containers, as they can react with the acids in the potatoes and cause discoloration and off-flavors.

You should store potatoes in a single layer or loosely packed, with some space between them to allow air movement. You should not stack potatoes too high or too tight, as this can cause pressure and damage to the potatoes. You should also check the containers regularly and remove any potatoes that show signs of spoilage.

4. Store Potatoes Away from Other Fruits and Vegetables

The fourth step for storing potatoes is to store potatoes away from other fruits and vegetables, especially those that produce ethylene gas, such as apples, bananas, onions, and tomatoes.

Ethylene gas is a plant hormone that triggers ripening and senescence in fruits and vegetables. Exposure to ethylene gas can cause potatoes to sprout faster and lose their quality.

Therefore, you should store potatoes separately from other produce or in a different room or cabinet. You should also avoid storing potatoes near sources of heat, such as stoves, ovens, radiators, or heaters.

You should also avoid storing potatoes near sources of moisture, such as sinks, faucets, or humidifiers.

Tips for Maintaining Potato Freshness

Potatoes are a versatile and nutritious vegetable that can be used in many dishes. However, they can also spoil quickly if not stored properly. To keep your potatoes fresh and tasty for longer, follow these simple tips:

1. Avoid washing potatoes until ready to use. Washing potatoes can remove some of the protective layer that prevents moisture loss and bacterial growth. Instead, store your potatoes in a cool, dark, and dry place, such as a pantry or a cellar. Avoid exposing them to sunlight, heat, or humidity, as these can cause them to sprout or rot faster.

2. Check on your potatoes regularly for any signs of spoilage. Potatoes can develop soft spots, mold, or a foul smell if they are past their prime. If you notice any of these signs, discard the affected potatoes immediately and check the rest for any damage. Do not eat potatoes that have a greenish hue, as this indicates the presence of a toxic substance called solanine, which can cause nausea, vomiting, and diarrhea.

3. Remove any sprouts or green spots before cooking. Sprouts and green spots are also signs of solanine production, and they can make your potatoes bitter and unpalatable. To remove them, simply cut them off with a sharp knife and discard them. You can still use the rest of the potato, as long as it is firm and odorless. However, if more than half of the potato is sprouted or green, it is better to throw it away and use a fresh one.

By following these tips, you can ensure that your potatoes stay fresh and delicious for longer. Potatoes are a great source of carbohydrates, fiber, vitamin C, and potassium, and they can be enjoyed in many ways. Whether you like them mashed, baked, roasted, or fried, potatoes are a staple food that you can always rely on.

In this article, we have discussed the best practices for storing potatoes to keep them fresh and tasty for longer. We have also provided some tips for selecting, preparing, and cooking potatoes for various dishes. Here is a summary of the main points and recommendations:

1. Potatoes are a nutritious and versatile food that can be enjoyed in many ways. They are rich in carbohydrates, fiber, potassium, vitamin C, and other phytochemicals that have health benefits.

2. Potatoes should be stored in a cool, dark, and well-ventilated place, such as a pantry, cellar, basement, or garage. The ideal temperature range is 45–50°F (6–10°C). Avoid storing potatoes in the refrigerator, as this can cause them to turn sweet and lose their flavor and texture.

3. Potatoes should be kept away from light, moisture, and other produce, especially onions. Exposure to light can cause potatoes to turn green and produce solanine, a toxic compound that can cause nausea, vomiting, and diarrhea. Moisture can lead to mold and rot, while other produce can emit gases that can accelerate sprouting and spoilage.

4. Potatoes should be inspected regularly and any damaged, rotten, or sprouted ones should be removed or used as soon as possible. Sprouted potatoes are still edible if they are firm and the sprouts are removed. Damaged or rotten potatoes can contaminate the rest of the batch and reduce their shelf life.

5. Potatoes should not be washed before storage, as this can increase the moisture level and promote decay. Potatoes should be washed only before cooking or eating. Scrub them gently under running water and pat them dry. Peel off any green or bruised areas.


6. Potatoes can be prepared in many ways, such as baking, boiling, roasting, frying, or dehydrating. Different types of potatoes have different characteristics and are suitable for different methods of cooking. For example, russet potatoes are starchy and fluffy, making them ideal for baking, mashing, or frying. Yukon gold potatoes are buttery and creamy, making them perfect for roasting, grilling, or mashing. Red potatoes are waxy and firm, making them great for salads, soups, or stews.
