What Are Sprouted Potatoes?
Sprouted potatoes are those that have begun to grow small shoots, known as sprouts, from the eyes of the potato. This often happens when potatoes are stored in a warm, light, or humid environment for an extended period.
Key Characteristics of Sprouted Potatoes:
– Development of small, white, or greenish shoots on the skin.
– Sometimes have a shriveled appearance due to loss of moisture.
Are Sprouted Potatoes Safe to Eat?
In general, it’s safer to avoid eating sprouted potatoes due to the increased levels of toxic compounds that can develop.
The Science Behind Solanine and Chaconine
Sprouted potatoes contain high levels of solanine and chaconine, glycoalkaloid toxins that are naturally found in nightshade family plants.
Effects of these toxins can include:
– Gastrointestinal distress (vomiting, diarrhea)
– Nervous system issues (headaches, dizziness)
For a detailed breakdown on glycoalkaloids, visit Oregon State University’s page on Potato Science.
Potential Health Risks
Consuming a large amount of sprouted potatoes can result in solanine poisoning, which manifests symptoms such as nausea, cramps, and breathing difficulties. In severe cases, it can be life-threatening.
How to Safely Prepare Sprouted Potatoes
It’s not recommended to eat sprouted potatoes, but if you have no other option, taking certain steps can minimize the risks.
Removing the Sprouts
- Cut off each sprout with a knife.
- Peel the potato skin, where most toxins are concentrated.
Cooking Methods
Cooking potatoes can reduce but not completely eliminate toxins. Proper methods include:
– Boiling
– Baking
– Cooking in high heat which can break down some glycoalkaloids

Preventing Potato Sprouting
Proper storage methods can help prevent sprouting:
- Store in a cool, dark, and dry place (45–50°F or 7–10°C).
- Keep them in a breathable paper or burlap bag, not plastic.
- Regularly check and remove any sprouting potatoes to halt further spread.
Alternatives to Using Sprouted Potatoes
If you’re unsure about sprouted potatoes, other subterranean options include:
- Sweet potatoes
- Turnips
- Rutabagas
- Carrots
These alternatives tend to have a longer shelf life and less risk of harmful toxins upon sprouting.
