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.
All cut onions that have leftover portions can be wrapped tightly in plastic wrap and stored in the refrigerator for up to 5 days. Store cooked onions in an airtight glass or plastic container. Do not store in a metal container because the metal can discolor the onions.
