I agree compeltely with Glauber Rocha; @Shirley, although you asked about storing in the refrigerator, it is worth noting also that caramelized onions store very well in the freezer, up to six months. â Bruce Goldstein Dec 12 '11 at 16:01.
When I use fresh onions, we store the unused parts for up to a week in our fridge in either a ziploc or a sealable rubbermaid-style container. For particularly pungent onions they go in the crisper drawer to keep the smell from being too strong in the rest of the fridge, but usually they're just on one of the shelves. Stilltasty says 2-3 days but my personal experience says otherwise.
