Knowing if an onion is bad is key for keeping food safe and tasty. As a chef, I’ve learned to spot visual and sensory signs to check if an onion is bad. These signs help you use only the freshest onions in your cooking.

Texture Changes: Soft Spots and Mushiness

One way to tell an onion is bad is by its texture. Look for soft spots or mushy areas. These can mean the onion is rotting or spoiling. Don’t use onions with soft or mushy spots as they can ruin your dish’s flavor and quality.

Maximizing Onion Shelf Life: Expert Chef Tips

As a professional chef, I’ve learned how to keep onions fresh longer. Keeping onions in the right place is key. Here are my best tips for keeping onions fresh:

Proper Ventilation and Temperature Control

Store whole, uncut onions in a cool, dry spot with good air flow. Put them in a pantry or cabinet away from sunlight and heat. This stops moisture from building up and slows down spoilage. Keep onions at a temperature between 40°F and 50°F to keep them fresh.
