How long can I keep sauteed onions in the fridge? I'm a working mom, so I'm always trying to find ways to cut down on cooking time. My newest trick is to saute a huge batch of onions and keep it in a container in the fridge, so that I can skip the onion-frying step of recipes. How long can I store sauteed onions in the fridge? I want to freeze any onions that I won't be able to use within a safe period of time, so I'm wondering how long that is.
Stilltasty.com gives you 3-5 days on cooked onions in the fridge - after that, tightly wrapped and airtight into the freezer.
