Onions are a staple in many kitchens, but they don't last forever. To determine if an onion has gone bad, start by examining its appearance. Fresh onions should have a firm texture and dry, papery skin. If the onion feels soft or has dark spots, it's likely spoiled. A sprouting onion is not necessarily bad, but it could be past its prime. Smell is another crucial indicator; a fresh onion has a mild, earthy aroma, whereas a spoiled onion emits a sharp, unpleasant odor. Check for mold, particularly around the neck and any cuts or bruises. Mold may appear as white, green, or black spots. If you notice a liquid or slimy texture, the onion is no longer good to use. Additionally, cut the onion open; if the flesh is discolored or mushy, discard it. Proper storage is key to extending an onion's shelf life. Store them in a cool, dry place with good air circulation, away from potatoes, which can speed up spoilage. By paying attention to these signs, you can ensure that your onions are fresh and safe to use in your culinary creations.

Onions can actually remain fresh for much longer than one might expect, as long as they are stored correctly. To fully extend the shelf life of onions, it's important to keep them in a cool, dark, and dry environment; a cellar or pantry works best. You can also store onions in the refrigerator or even the freezer for extended preservation.

The key to storing onions is to minimize moisture exposure. Often, the main cause of onion rot is moisture, whether from the surrounding environment or from other produce nearby, like potatoes. The more moisture onions encounter, the faster they tend to become soft.

Regardless of the onion variety, it's advisable to keep them whole to maximize their shelf life, as their skin serves as a natural barrier against moisture. Whole onions should be stored without any wrapping, such as the plastic bags used for transport from the store. However, once onions are cut or peeled, they should be placed in an airtight container to prevent spoilage.
