Are Onions Safe To Eat After They Sprout?
Onions are safe to eat after they sprout, but the flavor may not be as desirable. When onions start to sprout, it indicates that they are starting to break down and become less fresh. The sprouts themselves are not harmful to eat, but they can give the onion a bitter taste.
Instead of using up your sprouted onions right away, you can plant your sprouted onions — these are germinating bulbs from an onion plant. Since sprouting onions do not produce any poisonous substances, you can use them without any problems in your kitchen. An onion that is sprouting may become slightly limp once it has sprouted, but it is not poisonous or toxic, and will not harm you.
An onion that has sprouted is probably pretty old now, and you might need to peel off some of the outer layers which are dried out or squishy. As with sprouted onions, you may want to try peeling off some outer layers to reveal the crisp, fresh layers within, but the older an onion is, the more you will need to remove. If you split off sprouts within onion layers and plant them in potted soil, you will be able to grow new onions.
| Storage | Temperature | Shelf Life |
| Kitchen counter | 60-68°F | 1-2 days |
| Refrigerator | 32-34°F | 1 week |
| Freezer | 0°F | 3 months |
If you find that there is a small, squishy, or brownish area within the onions, you can just cut off this area and eat the rest of the onions. If only there is a tiny little blotch of mold in a section of your sprouting onion, just slice out the nasty, slimy bits and eat the rest. Just chop the sprouts (unless you want to eat them–take a taste and decide), slice the onion in half, and discard whatever remains of the sprouts.
After sending sugar and water into the green sprouts, the onions can have a slightly bitter flavor, and possibly be a bit stringier; you are likely to notice that if you are eating raw onions. If you see powdery green or brown mold on an onion, throw away the onion, as these spores may have found their way into the bulb, even when you have peeled off the outside. The cool air will help prevent mold spreading, but you will want to peel, rinse, and use the remaining onions ASAP.

This should help keep the onions fresh for as long as possible, so that you can use them to their full potential. Sliced onions will also last a shorter period and you will want to aim to use them within 10 days. It is definitely possible to keep onions in the refrigerator for a period of time, but they will not last as long as they will if you store them in the basement. If stored correctly, they will keep cool and edible for up to 3 months, but will mildew in some circumstances.
Onions are fairly tough, and even after you basically tear them up and remove half of the layers, they are likely still going to grow fine. Onions are not meant to be stored in the refrigerator, but you might be okay doing it if you plan on using them fairly soon. Unfortunately, the biggest issue with onions that start to sprout is how much onion you are going to waste.
If your onion is starting to sprout or grow, this may be a sign that you would not be willing to use it anymore in your recipes. If your chopped onion has been stored overnight, it may start to grow bacteria, and you would want to only use it as a cooked onion. On the other hand, it is possible if a peeled or chopped onion is left for a sufficient amount of time, it too can start to grow bacteria and may lead to disease if consumed.

For instance, a chopped onion certainly goes bad in one to two days without refrigeration, but a whole onion is probably okay as long as it is not refrigerated, but kept somewhere dry. Refrigerators are more likely to make the whole onions sprout more quickly because of moisture, and temperatures are also not going to be great.
Warm temperatures are also not great for onions, as this may increase the likelihood of the onion sprouting. If the onion has sprouted long, long ago, then the onion will have visibly exhausted, maybe even smelling. Exposure may make an onion begin to sprout in order to attempt root growth, sometimes onions can even begin to sprout stalks. Once an onion starts growing, take off the plastic bag and put the onion into a clear glass container.
Just cut off the stalk as it starts to form, and keep picking the green onions for cooking. If the onions that are sprouting put out flowers, you can wait for those flowers to fall to the ground, and save the seeds to plant the following season (unlike parent onions, those seeds will grow multiple onions when planted). Sprouts use the sugar stored in the parent onion as a power source, so the onions flesh will lose its sweetness as sprouts grow.
Just be aware that some onions are genetically modified and are not organic; so, they might have chemicals residues on them, or wax, and they may not make viable seeds. Best practices say that you should use cut onions ASAP, as quality and nutritional value deteriorates rapidly, but if they are not slimy to touch or have an off-putting smell, then they should do fine. Cut or chopped onions stored in the fridge last for up to one week, and once Cut or chopped onions are left overnight in the fridge, they should be used for cooking only, and should not be eaten raw.
In sauces or other dishes, you can safely eat leftovers for up to 4 days after they are stored properly, but onions alone tend to turn sloppy in just a few days. While onions can last a long time, they may undergo some changes when aging, which may cause you to hesitate before cooking them.
What to do with onions that have sprouted?
I recommend throwing away any onion that has sprouted, any onion that has black spots, or any onion that has rotten spots on it (even if it is growing). There are some cases where sprouts are just a little mushy, but they are not awful, and if they only have a few brown spots or have a few layers of a mushy or mushy onion, then you are able to replant them as long as they are still firm.
How do you know when an onion goes bad?
Onions that have been spoiled can develop dark spots, which will eventually lead to them growing mold once they have been damaged. As well as that, you should avoid onions that have sprouted because this is an indication that they are starting to go bad, so you should avoid them as well. Check the freshness of your onions by feeling them. It is time to replace onions with mushy or soft spots.
Why are my onions sprouting?
If your kitchen pantry gets too hot, your onions will sprout. If you keep your onions in the fridge for too long, they will become soft and taste strange. A cool room, basement, or a spot in the garage when temperatures are above freezing are all good places to store items.
