Tips and Tricks
You can, but I love the flavor of red onions the best. I have found that shallots hold flavor really well, too, if you want a smaller onion for things like salads.
These will last about 2-4 days on average, but even a day or so later, you can still cook up the onions to enjoy or use the marinade.
Marinated red onions are not stored in the fridge. The reason for this is if you are using a good quality olive oil (which you should be), then it will solidify when it's cold; therefore, you are not getting the onions coated in the liquid.
The short answer is it's your preference. I don't typically, but if you want to, you can in to order to keep anything from falling into them as they are out in your kitchen. I would also cover if you live in a warmer climate to help keep them fresher for longer.
