Are Potatoes Bad When They Sprout?

Are Potatoes Bad When They Sprout?

Have you reached for the potatoes in your pantry only to discover they have little nodules? Those light-colored arms that are beginning to grow are known as sprouts.

While sprouts may make your potato look scary, don’t toss it just yet!

Can You Eat a Potato That Has Sprouted?

The short answer: Yes, you can remove the sprouts and safely enjoy your potato.

Sprouts contain a high concentration of the glycoalkaloid Solanine. This compound can be toxic if consumed in large amounts. Therefore, the nodes themselves aren’t safe to eat. 

However, you can still salvage your potatoes by removing the nodules. Simply dig the entire sprout out before cooking it. A paring knife is usually the best tool for this job.  

When Should You Throw Them Away?

Sprouts can be removed for safe consumption, but there are a few things to look out for. 

If a potato is soft or shriveled, it’s time to throw it out. 

You may also notice some discoloration or dark spots. These should be cut away and discarded as well.

What if My Potato Has Turned Green?

You might also notice that a sprouted potato has a green hue. The color usually happens when potatoes are exposed to too much light. 

Remember Solanine? It’s also the culprit for that green color on the potato’s skin. 

Solanine is a neurotoxin that can make you sick if consumed in large amounts. Therefore, you should always peel off the green part of your potato and discard it.

What to Look for When Buying Potatoes

When searching for the perfect spud, always check for firmness. You’ll also want to avoid potatoes that have begun to sprout or turn green.

Be sure to store them in a cool, dark, dry place when you get them home. A pantry or cabinet is usually a safe place.
