Question: I thawed some frozen chicken breasts for dinner tonight, but now Iâve had a change in plans and donât have time to cook them. Is it okay if I refreeze them? Answer: Itâs fine to refreeze the chicken breasts â as long as you thawed them in the refrigerator and kept them there for no more than two days. If that was the case, you can pop the chicken breasts back into the freezer and theyâll still be safe to eat, says the United States Department of Agriculture. But keep in mind that thawing and refreezing any food will take a toll on its quality.
