We’ll show you exactly what to do next.
Storing Potatoes Correctly
So, the big question is, are potatoes supposed to be refrigerated? The short answer is generally no, but there are some important details to consider. Potatoes are root vegetables, and their ideal storage conditions are quite different from many other produce items you might put in your fridge.
Putting them in the wrong place can actually make them go bad faster or change their taste and texture for the worse.
Why Refrigeration Isn’t Usually Best
Refrigerators are cold and often humid. This environment can cause starch in potatoes to convert into sugar. When this happens, the potatoes can develop a slightly sweet taste.
More importantly, when you cook these sugary potatoes, the sugar can turn into acrylamide. This is a chemical that some studies suggest could be harmful if consumed in large amounts over time. While the risk is generally considered low for typical consumption, it’s a good reason to avoid refrigerating potatoes.
Also, the cold can affect the texture, making them watery or mushy when cooked.
The Ideal Storage Spot
The best place for potatoes is somewhere cool, dark, and dry. Think of a pantry, a basement, or a cool cupboard. The temperature should ideally be between 45-55 degrees Fahrenheit (7-13 degrees Celsius).
This range helps to slow down sprouting and spoilage without causing the negative effects of refrigeration.
Light Exposure
Direct sunlight or even bright indoor light is not good for potatoes. Light exposure can cause them to turn green. This green color indicates the presence of solanine, a natural toxin.
While you can usually cut away small green spots, large areas of green mean the potato is best discarded. Keeping potatoes in a dark place prevents this from happening.
Humidity Matters
Too much humidity can encourage mold and rot. Too little can cause them to dry out and become shriveled. The perfect spot will have moderate humidity, which is why a dark cupboard or pantry often works well.
Avoid storing them in plastic bags, as these trap moisture. Burlap sacks or paper bags are much better choices.
Proper Preparation for Storage
Before you store your potatoes, make sure they are dry. If you wash them before storing, you might introduce too much moisture. It’s usually best to brush off any excess dirt with a dry cloth or a soft brush.
If they are very dirty, you can rinse them quickly and then dry them thoroughly before storing. However, for most situations, brushing off dirt is sufficient.
What About Cut Potatoes?
If you have cut potatoes, the storage rules change. Once a potato is cut, its protective skin is gone. Cut potatoes should be stored in the refrigerator.
Place them in an airtight container or a resealable plastic bag. It’s a good idea to cover them with water to prevent them from drying out and turning brown. You’ll want to use cut potatoes within a day or two for the best quality.
Tips for Keeping Them Fresh Longer
Here are some easy tips to make your potatoes last longer:
- Store them in a single layer if possible. Overcrowding can lead to poor air circulation and spoilage.
- Keep them away from onions. Onions release gases that can cause potatoes to sprout and rot faster.
- Check them regularly. Remove any potatoes that show signs of sprouting or rot to prevent it from spreading to others.
- Don’t store them with fruits like apples or bananas, as these also release ethylene gas, which can speed up ripening and spoilage.
Sprouted Potatoes: What to Do
If your potatoes start to sprout, don’t panic. Small sprouts can simply be cut off. The potato itself is still good to eat.
However, if the sprouts are long and widespread, and the potato has become soft and shriveled, it’s probably best to discard it. This indicates the potato has used up most of its energy.
Green Potatoes: A Warning
As mentioned before, green spots on potatoes are a sign of solanine. You can cut away small green areas. If a large portion of the potato is green, or if the potato feels soft and has a bitter taste, it’s safer to throw it away.
This is especially important for children, who are more sensitive to solanine.
Can I Refrigerate Cooked Potatoes?
Yes, absolutely. Cooked potatoes, like mashed potatoes, baked potatoes, or potato salad, should always be refrigerated. Store them in an airtight container and consume them within three to four days.
This prevents the growth of bacteria that can cause foodborne illnesses. Reheating cooked potatoes thoroughly is also important.
The Role of Packaging
The type of packaging you use can make a difference. Paper bags or breathable mesh bags are ideal for raw potatoes. They allow for good air circulation, which helps prevent moisture buildup.
Avoid plastic bags, as they trap humidity and can lead to spoilage. If you buy potatoes in a plastic bag, consider transferring them to a more breathable container once you get home.
What About Very Hot Climates?
In very hot climates, a cool pantry might still be too warm. If you don’t have a consistently cool storage spot, you might have to compromise. Some people find that a very cold part of a refrigerator, like a crisper drawer, can work in a pinch, but it’s not ideal.
The key is to minimize the time they spend in less-than-ideal conditions.
Understanding Different Potato Types
While the general rules apply to most common potato varieties like Russets, Yukon Golds, and red potatoes, some very specific types might have slightly different optimal storage needs. However, for everyday home use, the cool, dark, dry storage method remains the most effective for all common types. The main goal is to keep them away from light, heat, and excessive moisture.
When to Discard Potatoes
It’s important to know when a potato has gone too far. Signs that a potato should be discarded include:
- Significant sprouting with soft, shriveled flesh.
- Large areas of greening, especially if accompanied by softness.
- An off smell, such as a strong, musty, or alcoholic odor.
- Visible mold growth.
- The potato feels mushy or slimy.
Making the Most of Your Potatoes
By following these simple storage guidelines, you can enjoy fresh, delicious potatoes for weeks. Proper storage not only saves you money by reducing waste but also ensures that your potatoes are safe and healthy to eat. It’s a small change that makes a big difference in your kitchen.
Frequently Asked Questions
Question: Should I wash my potatoes before storing them?
Answer: It’s generally best not to wash raw potatoes before storing them unless they are extremely dirty. Washing introduces moisture, which can speed up spoilage. Brush off excess dirt with a dry cloth instead.
If you must wash them, dry them thoroughly before storing.
Question: How long can potatoes be stored?
Answer: When stored correctly in a cool, dark, and dry place, potatoes can last for several weeks, often up to a month or even longer, depending on the variety and initial freshness.
Question: Can I store potatoes in a plastic bag?
Answer: It’s not recommended to store raw potatoes in plastic bags. Plastic traps moisture, which can lead to mold and spoilage. Breathable bags like paper bags, burlap sacks, or mesh bags are much better for air circulation.
Question: What happens if I store potatoes in the refrigerator?
Answer: Refrigerating potatoes can cause their starch to convert to sugar, leading to a sweet taste. When cooked, these sugars can form acrylamide, a chemical that is best avoided. The cold can also affect their texture, making them watery.
Question: Is it safe to eat potatoes that have started to sprout?
Answer: Yes, it is generally safe to eat potatoes that have sprouted, as long as you cut off the sprouts and any green areas. However, if the potato is very shriveled, soft, or has extensive sprouting, it’s best to discard it.
Final Thoughts
So, are potatoes supposed to be refrigerated? The simple answer is no, not typically. Keep them in a cool, dark, and dry place, away from onions.
This method preserves their taste and texture. Remember to avoid light to prevent greening and cut off sprouts when needed. Cooked potatoes, however, always go in the fridge.
Following these easy steps ensures your potatoes stay fresh and ready for your favorite meals.
