As I mentioned, this meatball recipe produces more meatballs than you may need in a single sitting. This makes them perfect for freezing and saving for later! u003cbr/u003eu003cbr/u003eThey last about three months in the freezer. When you are ready to serve the remaining meatballs, place them in the refrigerator overnight to defrost. Then, reheat them in the oven or stovetop until they are hot all the way through.
