Can You Eat Sprouted Potatoes …Here’s What You Need to Know

You’ve probably experienced it before.

You reach into the pantry, grab a potato for dinner, and notice several little “eyes” staring back at you. Tiny sprouts have begun growing from the surface, leaving you with an important question:

Are sprouted potatoes still safe to eat?

The answer isn’t always straightforward.

While potatoes are a kitchen staple that can last for weeks when stored properly, they don’t stay fresh forever. Once sprouts begin to appear, it’s worth taking a closer look before adding them to your next meal.

Here’s what causes potatoes to sprout, whether they’re safe to eat, and how to keep them fresh for longer.

Why Do Potatoes Sprout?

Potatoes are living plant structures, which means they naturally try to grow when conditions are favorable.

Sprouting usually occurs when potatoes are exposed to:

• Light
• Warm temperatures
• Humidity
• Ethylene gas from nearby produce, especially onions

If your potatoes are sitting on the kitchen counter, near a sunny window, or stored alongside onions, they’re more likely to develop sprouts.

Many people assume refrigeration will solve the problem, but surprisingly, storing potatoes in the refrigerator is not recommended.

Cold temperatures can convert some of the potato’s starch into sugar, affecting both flavor and texture when cooked.

Are Sprouted Potatoes Safe to Eat?

The answer depends on how far the sprouting process has progressed.

If the Sprouts Are Small

If the potato is still firm and only has a few small sprouts, you may be able to save it.

Remove:

• The sprouts
• The “eyes”
• Any green areas on the skin

Then peel the potato thoroughly before cooking.

If the Potato Is Wrinkled or Heavily Sprouted

If the potato has:

• Multiple large sprouts
• Wrinkled skin
• A shriveled appearance
• Soft spots

it’s best to throw it away.

At this stage, the potato has begun breaking down and may contain higher concentrations of naturally occurring toxins.

When in doubt, it’s safer to discard it.

The Hidden Toxins in Sprouted Potatoes

All potatoes naturally contain compounds called:

• Solanine
• Chaconine

These substances help protect the potato from insects and disease.

In fresh potatoes, the levels are generally low and not a concern.

However, as potatoes age, sprout, or become exposed to light, these compounds can increase.

The highest concentrations are typically found in:

• Sprouts
• Eyes
• Green portions of the skin

The white flesh of the potato contains much lower levels.

Consuming large amounts of these toxins may lead to symptoms such as:

• Nausea
• Vomiting
• Diarrhea
• Stomach pain
• Headache
• Fever

Most cases are mild, but some individuals may experience more severe reactions.

Does Cooking Destroy the Toxins?

Unfortunately, cooking alone does not completely eliminate solanine and chaconine.

Boiling, baking, frying, or roasting may reduce some toxins, but significant amounts can remain if sprouts and green areas are not removed first.

That’s why proper trimming and peeling are important whenever you choose to use a lightly sprouted potato.

And raw sprouted potatoes should never be eaten.

What About Green Potatoes?

Have you ever noticed a potato turning green?

The green color itself comes from chlorophyll, the pigment plants use during photosynthesis.

Chlorophyll isn’t harmful.

However, green potatoes often contain elevated levels of solanine and chaconine because both develop under similar conditions—primarily exposure to light.

If only a small area is green, you can sometimes cut it away.

If much of the potato is green, it’s safest to throw it out.

How to Prevent Potatoes From Sprouting

Proper storage can significantly extend the life of your potatoes.

Store Them in a Cool, Dark Place

Ideal locations include:

• A pantry
• A cupboard
• A basement storage area

Avoid direct sunlight and excessive heat.

Keep Potatoes Away from Onions

Onions release gases that can speed up sprouting. Store these vegetables separately whenever possible.

Use Breathable Storage Containers

Potatoes need airflow.

Good options include:

• Mesh bags
• Cotton storage bags
• Wire baskets

Avoid sealed plastic bags, which can trap moisture and encourage spoilage.

Buy Only What You’ll Use

While large bags often seem like a bargain, buying more potatoes than you can use increases the chances of spoilage before they’re eaten.

Other Signs a Potato Has Gone Bad

Sprouting isn’t the only warning sign.

Discard potatoes that are:

Soft or Mushy

Fresh potatoes should feel firm and solid.

Deeply Wrinkled

Significant shriveling indicates moisture loss and aging.

Covered in Dark Spots or Mold

Black spots, mold growth, or extensive bruising are signs of deterioration.

Bad-Smelling

Fresh potatoes have a mild, earthy scent.

If you notice a musty, moldy, or unpleasant odor, the potato should be discarded immediately.

Final Thoughts

A few tiny sprouts don’t automatically mean a potato belongs in the trash.

If the potato is still firm and the sprouts are small, carefully removing the sprouts, eyes, and any green areas may make it usable.

However, heavily sprouted, green, wrinkled, or soft potatoes should be discarded to avoid potential exposure to harmful toxins.

The best approach is simple:

When a potato looks questionable, trust your instincts.

A fresh potato is inexpensive to replace, but foodborne illness is far more costly.

Quick Rule of Thumb

✔ Firm potato + small sprouts = usually salvageable after trimming
✔ Large sprouts + wrinkles + green patches = throw it away

When it comes to food safety, it’s always better to be cautious than sorry.
