You reach into the pantry for a potato and find a few pale sprouts pushing out of the skin. It’s tempting to toss the whole bag, but the better question is a smaller one: should you use potatoes that are sprouting? In most cases, yes—if the potatoes are still firm and not green. Sprouting means the potato is doing what potatoes do: waking up to grow. With a little attention at the cutting board, you can usually save them.
Is a Sprouted Potato Safe to Eat?
Potatoes form solanine, a natural compound that protects them from pests. When a potato sprouts, or is exposed to light, solanine levels rise. In large amounts, it can cause stomach upset and a bitter taste. Cooking doesn’t reliably remove solanine, so the safest move is to cut away the parts that contain it: the sprouts, the eyes, and any green patches.
If the potato is firm and smells earthy, the rest of the flesh is fine to eat. If the potato has sprouted substantially and turned soft, wrinkly, or green, the quality has dropped and the whole potato may taste unpleasant. That’s when you should let it go.
When to Use Sprouted Potatoes
Use this quick guide when sorting through a bag:
| What the potato looks like | What to do |
|---|---|
| Firm with small, pale sprouts | Can use. Cut off sprouts with a generous margin, then peel. |
| Firm with a few small green patches | Use if you peel deeply and remove all green flesh. Bitter or green flesh all over? Toss it. |
| Soft, wrinkled, or spongy | Discard. The texture will be past its prime, and the flavor may be off. |
| Many long sprouts or large green areas | Discard. Solanine levels are likely higher, and the taste will be poor. |
How to Prep Sprouted Potatoes
- Scrub the potato well under cool water.
- Use a paring knife to carve out the sprouts and any dimpled eyes, going about 1⁄2 inch beyond each sprout.
- Peel the potato and inspect for green areas under the skin. Cut out every bit of green flesh.
- Cook promptly; boiling, roasting, or mashing all work.
🥔 Note: If a sprouted potato tastes unusually bitter after cooking, stop eating it. Bitterness can signal higher solanine, and it won’t improve with more cooking.
Cut Down on Sprouting
Potatoes sprout fastest in warm, bright places. Store them loose in a paper bag or an open bowl in a cool, dark cabinet or pantry, away from onions and direct sunlight. Buy only what you’ll use in two to three weeks, and check the bag before you shop so you’re not bringing home sprouts from the store.
When you spot a few sprouts on an otherwise firm potato, don’t panic. Cut carefully, trust your senses, and use the good parts for tonight’s dinner. If a potato feels soft, tastes bitter, or looks heavily green, compost it and move on. A little inspection now saves money and keeps your meals safe.
