The telltale signs that caramelized onions have gone bad are a sour smell, moldy patches, or a slimy texture. If you notice any of these, it's time to throw them away. Always trust your senses when it comes to determining the freshness of your ingredients.
Tips for storing Caramelized Onions to extend shelf life
• Always store caramelized onions in a sealed, airtight container. The less air they're exposed to, the longer they'll last.
• Keep them in the refrigerator, not at room temperature.
• If you want to store them even longer, consider freezing your caramelized onions. Be sure to store them in small portions so you can easily remove a portion without defrosting the whole batch. Once frozen, defrost them by moving to the fridge 24 hours before you plan to use them.
• Avoid storing onions near potatoes. Potatoes release gases that can speed up the spoiling process of onions.
