A: Chopped or sliced onions can be stored in a sealed container in your refrigerator at the proper temperature of 40Â°F or below for 7 to 10 days (Source: USDA). For pre-cut fresh or frozen products, always use and follow manufactures use by dates.
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.
