How Long Cut Onions Last in the Fridge: A Detailed Guide
Onions are a staple in many kitchens, adding flavor and nutrition to countless dishes. But what happens when you cut an onion and don’t use it all? How long does it last in the fridge? In this comprehensive guide, we’ll delve into the world of cut onions, exploring their shelf life, storage techniques, and tips for keeping them fresh.
Fresh onions can last for weeks in a cool, dry place, but once they’re cut, their lifespan significantly diminishes. Oxygen and moisture accelerate the spoilage process, causing the onion to lose its flavor and texture.
How to Store Cut Onions
Refrigerator Storage
To maximize the shelf life of cut onions, proper storage is crucial. Here’s how to store cut onions in the fridge:
- Wrap tightly: Wrap the cut onion securely in plastic wrap, aluminum foil, or an airtight container to prevent contact with air and moisture.
- Keep it cold: Place the wrapped onion in the coldest part of the fridge, usually the bottom shelf or produce drawer.
Freezing (Not Recommended)
Freezing onions is not an ideal storage method due to their high water content. Freezing can alter their texture and flavor.
