Keep an eye out for mold, off smells, or sliminess. If you spot any of these red flags, it’s time to bid adieu to those onions and toss them in the compost bin. Remember, when in doubt, throw it out!

Extra tip: To prevent your caramelized onions from going bad too soon, try adding a splash of vinegar before storing them. The acidity can help preserve them for a bit longer. Happy cooking!

Proper Storage Methods

When it comes to extending the freshness of caramelized onions, proper storage is key. Once cooled to room temperature, store them in an airtight container in the refrigerator. This will help prevent any moisture from seeping in and causing them to spoil quickly. Properly stored caramelized onions can last up to 1 week in the fridge. Remember to always use a clean utensil when scooping them out to avoid introducing any bacteria.
