The sauce with meatballs (but without pasta) should freeze without problems. After cooking, chill and chill the meatballs and sauce as quickly as possible (and within 2 hours after preparation) and then transfer them to airtight containers and freeze them for up to 3 months. Most cooked meatballs can be eaten in the freezer after 3 to 4 months. Of course, this assumes that they have been properly stored: cooked meatballs must be placed in an airtight container or bag before freezing.
