You can sometimes still eat potatoes after they sprout, but only if they meet some strict safety checks and you handle them carefully.

Quick Scoop

  • Sprouted potatoes develop higher levels of natural toxins called glycoalkaloids (especially solanine), which can cause food poisoning if levels get too high.
  • Light sprouting on a firm, non‑green potato can often be made safer by cutting out the sprouts and any green or damaged areas generously.
  • If the potato is very wrinkled, soft, bitter, heavily green, or covered in long sprouts, it is safer to throw it away instead of trying to salvage it.

When It’s Usually Safe

Use these checks before deciding to cook:

  • The potato is still firm and not shriveled or rubbery.
  • Sprouts are small/short, and there aren’t too many of them.
  • There’s little or no green coloring on the skin or flesh.
  • You fully remove:
    • All sprouts (“eyes”)
    • Any green patches
    • Any bruised or damaged areas
      by cutting at least a few millimeters around them.

Even then, some experts recommend avoiding sprouted potatoes altogether because toxin levels are hard to measure at home.

When You Should Toss Them

Definitely do not eat sprouted potatoes if:

  • They are soft, wrinkled, or dried out.
  • The sprouts are long and well developed, or there are many of them.
  • The potato has large areas of green skin or flesh.
  • It smells off or tastes bitter when you cook a small piece (bitterness can signal high glycoalkaloids).

People who are pregnant, young children, and older adults should be extra cautious and avoid sprouted potatoes entirely because they may be more vulnerable to toxin effects.

What Can Go Wrong

Glycoalkaloid poisoning from potatoes is rare but real. Symptoms can include:

  • Nausea, vomiting, and diarrhea
  • Stomach cramps and abdominal pain
  • Headache, dizziness, confusion, fever, low blood pressure, or rapid pulse in severe cases

Symptoms may show up within a few hours or be delayed up to a day after eating.

Smart Storage To Avoid Sprouts

To slow down sprouting and keep future potatoes safer:

  • Store potatoes in a cool, dark, well‑ventilated place (not the fridge, which can affect flavor and sugar content).
  • Keep them away from onions, which can make each other spoil faster.
  • Use older potatoes first and check the bag or basket regularly so they don’t sit for months.

Bottom line: Very lightly sprouted, firm, non‑green potatoes can sometimes be trimmed and eaten, but heavily sprouted, soft, or green potatoes should go straight to the bin for safety.
