Can Thawed Chicken Nuggets Be Refrozen. But pay attention to the way you thaw and, conversely, the way you freeze. Most foods previously frozen, thawed and then cooked can be refrozen as long as they have not been sitting at room temperature for more than two hours.
It takes about a full day to completely thaw a pound of boneless chicken. The problem is that because they have already been cooked, they will be dry when you thaw and cook them again. You can refreeze cooked meat and fish once, as long as they have been cooled before going into the freezer.
